Wai O Keanalele

“Wai o ke ola! Wai, waiwai nui! Wai, nā mea a pau, ka wai, waiwai no kēlā!”  (Water is life! Water is of great value! Water, the water is that which is of value for all things!) (Joe Rosa; Maly)

Water was so valuable to Hawaiians that they used the word “wai” to indicate wealth. Thus, to signify abundance and prosperity, Hawaiians would say waiwai.

“Kekaha wai ‘ole na Kona” (“waterless Kekaha of the Kona district”) speaks of Kekaha, the portion of North Kona extending north of Kailua Bay from Honokōhau to ʻAnaehoʻomalu.  It is described as “a dry, sun-baked land.”)

Kamakau notes during the 1770s, “Kekaha and the lands of that section” were held by descendants of the Nahulu line, Kameʻeiamoku (living at Kaʻūpūlehu) and Kamanawa (at Kīholo,) the twin half-brothers of Keʻeaumoku, the Hawai‘i island chief.

It is the home of Kamanawa, at Kīholo, and its fresh water resources that we look at today.

Situated within the ahupuaʻa of Puʻuwaʻawaʻa, this area has ancient to relatively recent (1801 Hualālai eruption and the 1859 Pu‘u Anahulu eruption.)

Kīholo (lit. the Fishhook) refers to the legend which describes how in 1859 the goddess Pele, hungry for the ‘awa and mullet, or ʻanae, which grew there in the great fishpond constructed by Kamehameha I, sent down a destructive lava flow, grasping at the fish she desired.  (DLNR)

This place name may have been selected as a word descriptive of the coastline along that part of the island where the east-west coast meets the north-south coast and forms a bend similar to the angle between the point and the shank of a large fishhook.

There is no confirmation for this theory, except for our knowledge that Hawaiian place names have a strong tendency to be descriptive.  (Kelly)

While only a handful of houses are here today, in ancient times, there was a village that with many more that called Kiholo home.

“This village exhibits another monument of the genius of Tamehameha (Kamehameha I.) A small bay, perhaps half a mile across, runs inland for a considerable distance. From one side to the other of this bay, Tamehameha built a strong stone wall, six feet high in some places, and twenty feet wide, by which he had an excellent fish-pond that is not less than two miles in circumference.”

“There were several arches in the wall, which were guarded by strong stakes driven into the ground so far apart as to admit the water of the sea; yet sufficiently close to prevent the fish from escaping. It was well stocked with fish, and water-fowl were seen swimming on its surface.” (Ellis, 1823)

Where it was feasible, sometimes in small embayments, and other times directly on the coastal reefs, Hawaiians built walled ponds (loko kuapā) by building a stone wall, either in a large semicircle – from the land out onto the reef and, circling around, back again to the land—or to connect the headlands of a bay, they enclosed portions of the coastal waters, often covering many acres.

These ponds provided sanctuaries for many types of herbivorous fish. One or more sluice gates (mākāhā) built into the wall of a pond allowed clean, nutritious ocean water and very young fish to enter the pond. This was the type of fishpond that was reported to have been built at Kīholo by early visitors to the area.  (Kelly)

While Ellis credits Kamehameha with building Ka Loko o Kīholo (The Pond of Kīholo,) it is more likely that the fishpond was built in the fifteenth to the early part of the seventh centuries and that Kamehameha later repaired and rebuilt it.  (Kelly)

It was in operation well after that.  “Took the road from Kapalaoa to Kailua on foot. Passed the great fish pond at Kīholo, one of the artificial wonders of Hawaiʻi; an immense work! A prodigious wall run through a portion of the ocean, a channel for the water etc. Half of Hawaii worked on it in the days of Kamehameha.”  (Lorenzo Lyons, August, 8, 1843; Maly)

Fishing and fish from the pond provided much of the food for the villagers.  In addition, due to the limited rainfall and no surface streams, they also planted sweet potatoes, at least seasonally (probably just before the winter rains were expected, whatever soil was available was piled in heaps and nourished with leaves and other vegetable matter.)  (Kelly)

Kīholo and other ponds (ie Pā‘aiea (once where the Kona Airport is situated)) would have supplied food for Kamehameha’s warriors when they sailed off in the great canoe fleet to conquer the chiefs on the Islands of Maui, Moloka‘i and O‘ahu in 1794 and 1795. (Kelly)

“The natives of this district (also produced) large quantities of salt, by evaporating sea water. We saw a number of their pans, in the disposition of which they display great ingenuity. They have generally one large pond near the sea, into which the water flows by a channel cut through the rocks, or is carried thither by the natives in large calabashes.”  (Ellis, 1823)

“After remaining there some time, it is conducted into a number of smaller pans about six or eight inches in depth, which are made with great care, and frequently lined with large evergreen leaves, in order to prevent absorption. Along the narrow banks or partitions between the different pans, we saw a number of large evergreen leaves placed.”

“They were tied up at each end, so as to resemble a shallow dish, and filled with sea water, in which the crystals of salt were abundant. … it has ever been an essential article with the Sandwich Islanders, who eat it very freely with their food, and use large quantities in preserving their fish.”  (Ellis, 1823)

“Salt was one of the necessaries and was a condiment used with fish and meat, also as a relish with fresh food. Salt was manufactured only in certain places. The women brought sea water in calabashes or conducted it in ditches to natural holes, hollows, and shallow ponds (kaheka) on the sea coast, where it soon became strong brine from evaporation. Thence it was transferred to another hollow, or shallow vat, where crystallization into salt was completed.”  (Malo)

The 1850s saw several outbreaks of lava from Mauna Loa: in August 1851; in February 1852 (it came within a few hundred yards of Hilo;) and in August 1855, when it flowed for 16-months.

Then, in 1859, activity shifted to the northwestern side of the mountain. A flow started on January 23rd at an elevation of 10,500 feet; it came down to the sea on the northwest coast in two branches, at a point just north of Kīholo. On January 31st the stream had reached the sea, more than thirty-three miles in a direct line from its source – the first eruption in historic times from a high altitude to accomplish the extraordinary feat.  (Bryan, 1915)

The 1859 flow basically destroyed Kīholo and transformed it from a former residence of chiefs to a sparsely populated fishing village.  In the early 20th century, Kīholo became the port for Puʻuwaʻawaʻa Ranch, some 10 miles inland near Puʻuanahulu. Cattle were shipped from Kīholo to Honolulu until 1958. The construction of Queen Kaʻahumanu Highway in 1975 ended Kīholo’s former isolation.  (Kona Historical Society)

What about the water?

Today, evidence remains of the fresh groundwater flow through subterranean lava tubes and chambers out into the bay.   There is a series of caves in Puʻuwaʻawaʻa that was formed from lava tubes. The ceilings of lava tubes often collapsed in some places and were left intact in others, forming caves with relatively easy access through the collapsed areas.

Such caves were used for shelters by Hawaiians, perhaps during the summer months when they came to gather salt or to fish. The place name Keanalele (the discontinuous cave) is descriptive of caves found just inland of the coast in the ahupua‘a of Pu‘uwa‘awa‘a between Kīholo and Luahinewai (more on this in another post.)

Some of the caves contain fresh or brackish water, particularly those located toward the makai (seaward) end of the cave series. Caves that contained water were precious to the inhabitants of the area, even if the water in them was slightly brackish.  (Kelly)  One of these is identified as Wai O Keanalele, with three feet of almost fresh water..

On January 25, 2002 the Board of Land and Natural Resources transferred responsibility for State-managed lands within the ahupua‘a of Pu‘uwa‘awa‘a and Pu‘u Anahulu from its Land Division to the Divisions of Forestry and Wildlife (DOFAW) and State Parks.

The portion that was made the responsibility of the Division of State Parks was designated the Kīholo State Park Reserve.  The Kīholo State Park Reserve is comprised of 4,362 acres and includes an 8-mile long wild coastline along the Kona Coast of the Island of Hawai‘i (bounded by Queen Kaʻahumanu Highway on the east, the Pu‘uwa‘awa‘a/Kaʻupulehu district boundary on the south, the shoreline on the west and the Pu‘u Anahulu/ʻAnaehoʻomalu ahupua‘a boundary on the north.)

Kaloko-Honokōhau National Historical Park (KAHO)

Kaloko-Honokōhau National Historical Park (KAHO) was established in the Kekaha region of North Kona (Kailua to Kalaoa) in 1978 in order to preserve and protect traditional native Hawaiian culture and cultural sites.

The park is the site of an ancient Hawaiian settlement and is considered a locale of considerable cultural and historical significance. Cultural resources include fishponds, petroglyphs and a heiau (temple.)

The physical location of Kaloko-Honokōhau made the settlement easy to manage. Situated on the lower portions of a sloping terrain, the settlement’s activities were directed by kahuna chiefs, from a vantage point, such as the bluff overlooking the fishpond of ʻAimakapā, where a commanding view of Kaloko-Honokōhau was available.

“In ancient times, the chiefs would regularly live along the shore, that is, the chiefs of Kaloko and Honokōhau. At the place called Ahauhale, is where the chiefs of Kaloko lived. The place called Waihalulu, is where the chiefs of Honokōhau lived.”  (“Ka Wai o Kahinihini‘ula” (1923) Kumu Pono)

“There were men, women, and children, the houses were filled with large families. Truly there were many people (in Kekaha.) …  The lands of Honokōhau were filled with people in those days, there were many women and children with whom I traveled with joy in the days of my youth.  Kaloko was the same … Those families are all gone, and the land is quiet. There are no people, only the rocks remain, and a few scattered trees growing, and only occasionally does one meet with a man today”.  (“Na Hoonanea o ka Manawa” (1924) Kumu Pono)

The two dominant features in the Kaloko-Honokōhau National Park are Kaloko and ʻAimakapā Ponds.  (Prior to conversion and utilization as ponds, they were originally inland bays.)

The two ponds are different types of Hawaiian fishponds.  Kaloko is a loko kuapā (what we consider the typical coastal fishpond, artificially enclosed by an arc-shaped seawall (or in this case a seawall enclosing the mouth of a small bay) and containing at least one sluice gate (mākāhā.))

ʻAimakapā is a loko puʻuone (an shore fishpond containing either brackish or a mixture of brackish and fresh water, formed by development of a barrier beach paralleling the coast and connected to the ocean by a channel or ditch.)

Nearby (also in the Park) are the remnants of the ʻAiʻōpio fishtrap.  An opening in the trap to the sea enabled fish to enter, and the walled sections of the trap allowed fish to be stored until needed.

At high tide, fish entered the trap by swimming through the seaward opening or over the submerged walls.  At low tide, the fish were trapped in the enclosure and were easily netted.  Fishtraps differ from fishponds in that the fish are trapped and caught, but not raised.

The 1,160 acre park, a landscape of rugged lava rock, was at one time a thriving ancient Hawaiian settlement. More than 200 archeological sites document the Hawaiian’s use of the area over time.

The Hawaiians of this ancient settlement harvested fish from the sea and from fishponds they constructed. They grew coconuts, sweet potatoes and gourds and raised chickens and pigs.

Those living closest to the shore harvested fish and other food from the sea, while others living within the ahupuaʻa (sea to mountain land division) grew staple resources such as taro, breadfruit, paper mulberry, wood, and fiber for clothing. To ensure everyone’s survival, they would trade these items with one another.

Archeological resources at Kaloko-Honokōhau National Historical Park also include kahua (ancient house site platforms), heiau (temples,) a holua (toboggan slide), kiʻi pōhaku (petroglyphs), papamu (kokane game boards), stone enclosures, ahus (stone mounds that serve as altars, shrines, or security mounds), lava tube shelters and parts of the Māmalahoa Trail (Kings trail.)

Of all the Aliʻi associated with Kaloko-Honokōhau, the most famous is Kamehameha l, who settled and established his Royal Center at Kamakahonu in Kailua-Kona.  (Some believe Kamehameha was buried at Kaloko.  Kaloko is also believed to be the resting place of King Kahekili from Maui.)

Hale Ho’okipa Visitor Center, the Hawaii Pacific Parks Association store, and the adjoining parking area are open from 8:30 am to 4:00 PM daily.  (The Kaloko road gate is open from 8:00 am to 5:00 PM daily.)  Admission to the park is Free.

Luahinewai

“Kekaha wai ‘ole na Kona” (“waterless Kekaha of the Kona district”) speaks of Kekaha, the portion of North Kona extending north of Kailua Bay from Honokōhau to ʻAnaehoʻomalu.  It is described as “a dry, sun-baked land.”

Here is Kīholo, situated within the ahupuaʻa of Puʻuwaʻawaʻa.  Kīholo (lit. the Fishhook) refers to the legend which describes how in 1859 the goddess Pele, hungry for the ‘awa and mullet, or ʻanae, which grew there in the great fishpond constructed by Kamehameha I, sent down a destructive lava flow, grasping at the fish she desired.  (DLNR)

This place name may have been selected as a word descriptive of the coastline along that part of the island where the east-west coast meets the north-south coast and forms a bend similar to the angle between the point and the shank of a large fishhook. There is no confirmation for this theory, except for our knowledge that Hawaiian place names have a strong tendency to be descriptive.  (Kelly)

While only a handful of houses are here today, in ancient times, there was a fishing village with many more that called Kīholo home.

Here, too, is Luahinewai, an anchialine pond/pool – (these are shoreline pools without surface connection to the sea, having waters of varying salinity and showing tidal rhythms (Brock.))  Luahinewai (old lady’s water) is said to refer to a water-formed supernatural moʻo (lizard) that lived there.

Of Luahinewai, JWHI Kihe writes (in Ka Hoku o Hawaiʻi; Maly:)
“There is a large pond near Kīholo and Laemanō; it is a famous bathing place of the chiefs of ancient times. The water there is cold, and causes the skin to tingle. Because it is so cold, it is like ice water.”

“It is said that there is an opening in this pond by which an old woman (luahine) enters. And there below the pond, are said to be laid out the bones of the chiefs of ancient times.”

“This pond is about five fathoms deep at its deepest point near the center of the pond. That too, is where the water is coldest. And if you should dive in and pass this area, you will find the cold water and not be able to stay there long. You will quickly retreat and wrap yourself up with a cloth.”

“The one who dives into it at its deepest point, will also see that his/her skin will turn red like the red coral. There are also pebbles at the bottoms of this pond, and it is a good thing, as you will not strike your foot upon any rocks.”

“The chiefs and fearless warriors of ancient times have passed from this side of the dark waters of death, and the bathing pool of Luahine Wai remains with its beauty, playing in the ocean mist and the gentle blowing of the breezes. This generation too, shall pass, and the next generation that follows, but Luahinewai shall remain as was found in the beginning.”

Luahinewai was a famous rest stop during canoe voyages along the coast.  (Ulukau) “… the ship sailed, pausing at Luahinewai to bathe and visit with that strange water in the lava.  After an enjoyable stop at the water with the pretty pebbles, they again sailed.”  (ʻĪʻi)

In 1790, Kamehameha I and his chiefs were living at Kawaihae. Following advice of a priest from Kaua‘i, Kamehameha undertook the reconstruction of the heiau Pu‘u Koholā, to dedicate it as a house for his god Kūkaʻilimoku.  During this time, “thousands of people were encamped on the neighboring hillsides.”

According to Kamakau, Kamehameha “… summoned his counselors and younger brothers, chiefs of the family and chiefs of the guard, all the chiefs, lesser chiefs, and commoners of the whole district. Not one was allowed to be absent except for the women, because it was tabu to offer a woman upon the altar; a man alone could furnish such a sacrifice.”

“The building of the heiau of Pu‘u Koholā was, as in ancient times, directed by an expert—not in oratory, genealogy, or the prophetic art, but by a member of the class called hulihonua who knew the configuration of the earth (called kuhikuhi pu‘uone.)”

“Their knowledge was like that of the navigator who knows the latitude and longitude of each land, where the rocks are, the deep places, and the shallow, where it is cold and where warm, and can tell without mistake the degrees, east or west, north or south. Such knowledge, taught on Kauai, one could apply anywhere in the world; so Kapoukahi had instructed Ha‘alo‘u (a chiefess relative of Kamehameha’s) to the letter.”

“As soon as the heiau was completed, just before it was declared free, Kamehameha’s two counselors, Keaweaheulu and Kamanawa (who resided at Kīholo,) were sent to fetch Keōua, ruling chief of the eastern end of the island of Hawaiʻi”

“Keōua was living in Kaʻū mauka in Kahuku with his chiefs and warriors of his guard. Keaweaheulu and his companion landed at Ka‘iliki‘i and began the ascent to Kahehawahawa … Close to the extreme edge of the tabu enclosure of Keōua’s place the two … messengers rolled along in the dirt until they came to the place where Keōua was sitting, when they grasped his feet and wept.”

“We have come to fetch you, the son of our lord’s older brother, and to take you with us to Kona to meet your younger cousin, and you two to be our chiefs and we to be your uncles. So then let war cease between you.”

Keōua agreed to accompany his uncles. Some of the party traveled by foot overland, while Keōua and some of his trusted counselors and guards traveled with the messengers by canoe.

“They left Kailua and went as far as Luahinewai at Kekaha, where they landed the canoes. Keōua went to bathe, and after bathing he cut off the end of his penis (ʻomuʻo), an act which believers in sorcery call “the death of Uli,” and which was a certain sign that he knew he was about to die.

(“The death of Uli” refers to death caused by the vengeance of the sorcerer, since Uli is the goddess worshipped by Sorcerers. The part cut off is used for the purpose of sorcery so that those who do a man to death may themselves be discovered and punished.)  (DLNR)

They kept on their course until near Mailekini, when Keʻeaumoku and some others carrying spears, muskets, and other weapons broke through the formation of the fleet, surrounding the canoes of Keōua, separating them from those of Keaweaheulu and his followers and calling to Kamanawa to paddle ahead.

Keōua rose and called to Kamehameha, “Here I am!” Kamehameha called back, “Stand up and come forward that we may greet each other.” Keōua rose again, intending to spring ashore, when Keʻeaumoku thrust a spear at him, which Keōua dodged, snatched, and thrust back at Keʻeaumoku, who snatched it away. Keōua and all those who were with him on the canoe were killed… By the death of Keōua, Kuʻahuʻula and his placing in the heiau of Pu‘u Kohola the whole island of Hawaii became Kamehameha’s.”

Mānā, Kauaʻi

Mānā is a coastal plain with an ancient sea cliff at its inner edge, which extends from Waimea in the south to Barking Sands in the north on the western shores of Kauaʻi.

This region has been identified as a leina-a-ka-uhane (paths-for-leaping-by-the-spirit). These were almost always on bluffs looking westward over the ocean, from which the spirits of the dead were believed to plunge in order to enter the spiritual realm.

Throughout prehistory, large areas of the Mānā Plain were covered by the great Mānā swamp, allowing the ancients to canoe as far south as Waimea.

Up until the mid-1880s, the great Mānā swamp, east of the plain, covered large areas of the lowlands.  Approximately 1,700-acres of permanent, semi-permanent and seasonal wetlands were present on the Mānā Plain.

It is believed that these wet conditions encouraged the independent invention of aquaculture on Kauaʻi and the construction of stone and earthen ponds for growing staples such as taro, yam and sweet potatoes.

Historically, native Hawaiians constructed four different types of fishponds – freshwater taro ponds, other freshwater ponds, brackish water ponds and seawater ponds.

Aquaculture was employed to supplement their other fishing activities, and permanent fishponds guaranteed a stable food supply for populations in lean times.  Tended ponds provided fish without requiring fishing expertise, and harvesting the pond, unlike fishing at sea, was not weather dependent.

Evidence suggests that Hawaiian fishponds were constructed as early as AD 1000, if not earlier, and continued to be built until the 1820s.

After the arrival of Europeans to the island, aquaculture transitioned to agriculture through the eventual draining of the swamp and the cultivation of sugar cane and rice.

The first successful sugar plantation to export from the islands was established at Kōloa in 1835, and by the 1930s, nearly all of the Mānā swamp had been filled to produce this crop.

Up until the mid-1880s, the great Mānā swamp covered large areas of the lowlands.  One of the first European settlers, Valdemar Knudsen, drained a portion of the Mānā swamp be excavating a ditch through to the ocean at Waiele.  The first sugarcane was planted in Kekaha in 1878.

Hans Peter (HP) Faye was a Norwegian immigrant (arriving in 1880) who started a small plantation at Mānā and eventually helped form Kekaha Sugar, incorporated 1898, and became its first manager.

It was his vision that created the Kekaha and Kokeʻe Ditch Systems and the intricate drainage canals that drain the large swamps of Mānā.

To keep the groundwater table below the root zone of the sugar cane, thousands of feet of canals were excavated to drain excess water from the soil.  The water is then pumped into canals such as the Nohili Ditch for release into the ocean.

The drainage system, with two pumps at the Kawaiele and Nohili pumping stations, was constantly running to lower the groundwater table, which made possible for sugarcane cultivation.

Rice was planted in the drained swamplands from the mid-1860s to 1922.  By the 1930s, nearly all of the Mānā swamp had been filled in and planted in sugarcane.

The need to keep the area drained continues today.  These pumping stations must continue running to keep the groundwater table from rising too high, which could result in root rots and hence low crop yields. During storm season, with five inches of rain in one day would result in flooding.

Nearby wetlands form the Kawaiele Sand Mine Sanctuary (a State Waterbird Refuge for Hawaii’s four endangered waterbird species – Hawaiian duck, coot, stilt and moorhen;) this was created during a sand removal program.

When I was at DLNR, we authorized the sale of sand licenses to allow contractors to remove sand for construction projects (golf courses, concrete mix and beach replenishment) within the waterbird sanctuary that, in turn, created a beneficial mixed terrain and expanded the waterbird habitat.

The map is a portion of a 1910 USGS quadrant map noting Mānā and the inland wetlands.  In addition, I have added other related images in a folder of like name in the Photos section on my Facebook and Google+ pages.

Telling Time

Does anybody really know what time it is?  Does anybody really care?

The answer to both is Yes … and Kauaʻi, Hawaiʻi has the distinction of being one of only two official Time broadcast points in the United States (the other is in Fort Collins, Colorado.)

At first, I thought “Time” was a pretty simple thing.  Oh yeah, every now and then we need to mentally add or subtract an extra hour between points on the continent – and most folks there need to adjust for “Daylight” or not – but in looking into the Kauaʻi operation, I quickly learned that there are many variables of “Time.”

OK, let’s fast forward past the daylight-darkness, sundial, wind-up and quartz watch timing eras … nowadays, transportation, communication, financial transactions, manufacturing, electric power and many other technologies have become dependent on accurate clocks; folks need to be more accurate than being “about” a certain time.

In addition, some folks need time referenced to the Earth’s rotation for applications such as celestial navigation, satellite observations of the Earth and some types of surveying.  For those folks, Time relative to the motion of the Earth is more important than the accuracy of the atomic clock (even though Earth time fluctuates by a few thousandths of a second a day.)

For the rest of us, highly accurate atomic clocks and the agreement in 1967 on what a “second” is (the duration of 9,192,631,770 cycles of the radiation associated with a specified transition of the cesium atom) led to a compromise time scale of the Coordinated Universal Time (UTC.)

The National Institute of Standards and Technology (NIST – an agency of the US Department of Commerce) laboratories in Boulder, Colorado does the computing for us and even broadcasts the UTC(NIST) via various means.  (UTC(NIST) is the US national standard for measurements of time-of-day, time interval and frequency.

Here’s the official statement on what they do: “UTC(NIST) is the coordinated universal time scale maintained at NIST. The UTC(NIST) time scale comprises an ensemble of cesium beam and hydrogen maser atomic clocks, which are regularly calibrated by the NIST primary frequency standard. The number of clocks in the time scale varies, but is typically around ten.”

“The outputs of the clocks are combined into a single signal by using a weighted average. The most stable clocks are assigned the most weight. The clocks in the UTC(NIST) time scale also contribute to the International Atomic Time (TAI) and Coordinated Universal Time (UTC).”

“UTC(NIST) serves as a national standard for frequency time interval, and time-of-day. It is distributed through the NIST time and frequency services and continuously compared to the time and frequency standards located around the world.”

Whoa, that’s waaay more information than I needed; … and, I think you are confusing me with someone who cares.  (Short answer, those guys “keep” the time.)  OK, let’s move on.

If you really want to know what Time it is, go to http://nist.time.gov , select your desired time zone in the US and the time will be displayed for you.

Or, call to hear the “Time” broadcasts by dialing (303) 499-7111 for WWV (Colorado) and (808) 335-4363 for WWVH (Hawaiʻi).

These are not toll-free numbers; callers outside the local calling area are charged for the call at regular long-distance rates.  The telephone time-of-day service is used to synchronize clocks and watches and for the calibration of stopwatches and timers. It receives about 2,000 calls per day.

OK, back to Kauaʻi.

At Kokole Point at Mānā, Kauaʻi, the NIST radio station WWVH broadcasts time and frequency information 24 hours per day, 7 days per week to listeners worldwide.  (These are the guys who “tell” the time.)

The information broadcast by WWVH includes time announcements, standard time intervals, standard frequencies, UT1 time corrections (time derived by astronomers who monitor the speed of the Earth’s rotation,) a BCD time code (time data is coded binary coded decimal (BCD) digits in the form HH:MM:SS:FF,) geophysical alerts, marine storm warnings and Global Positioning System (GPS) status reports.

Voice announcements are made from WWVH once every minute.  The announced time is “Coordinated Universal Time” (UTC).   Coordination with the international UTC time scale keeps NIST time signals in close agreement with signals from other time and frequency stations throughout the world.

UTC differs from local time by the number of time zones between your location and the zero meridian (which passes through Greenwich, England.) (In Hawaiʻi, it’s UTC – 10 (the online and telephone time broadcasts are calibrated for Hawaiʻi.))

UTC is a 24-hour clock system.  When local time changes from Daylight Saving to Standard Time, or vice versa, UTC does not change. However, the difference between UTC and local time may change by 1-hour.  UTC runs at an almost perfectly constant rate, since its rate is based on cesium atomic frequency standards.

In addition to the time-related data, NOAA uses WWVH to broadcast geophysical alert messages that provide information about solar terrestrial conditions. Marine storm warnings are broadcast for the Atlantic and Pacific oceans and the Gulf of Mexico. The National Weather Service provides the storm warning information.  (This information is broadcast at specific time intervals in each hour.)

Another critical function of the WWV system (especially for Hawaiʻi) is keeping the clocks on the GPS satellites in sync.  GPS technology requires very accurate timekeeping as the difference in radio signal arrival is a big part of fixing your location.  Without WWVH, the GPS system would drift off and lots of transportation and related functions would be affected (airplanes, ships, self-driving cars, etc.)

WWVH began operation on November 22, 1948 at Kihei on the island of Maui (the site now houses the Hawaiian Islands Humpback Whale National Marine Sanctuary offices.)   In July 1971, the station moved to its current location, near Kekaha, Kauaʻi.

For those wondering why these two facilities, that are west of the Mississippi River, have call signs that start with “W” (typically, station call signs west of the Mississippi start with “K” and those east start with “W,”) the time station’s early location was in Washington, DC (May 1920) – when it moved to Fort Collins (1966,) it kept the call sign.  For consistency, Kauaʻi followed the call sign pattern.

The image shows the WWVH facility on Kauaʻi; in addition, I have added other related images in a folder of like name in the Photos section on my Facebook and Google+ pages.
