Station HYPO , also known as Fleet Radio Unit Pacific ( FRUPAC ), was the United States Navy signals monitoring and cryptographic intelligence unit in Hawaii during World War II . It was one of two major Allied signals intelligence units, called Fleet Radio Units in the Pacific theaters , along with FRUMEL in Melbourne , Australia . The station took its initial name from the phonetic code at the time for "H" for Heʻeia, Hawaii radio tower. The precise importance and role of HYPO in penetrating the Japanese naval codes has been the subject of considerable controversy, reflecting internal tensions amongst US Navy cryptographic stations.
65-534: Wilfred J. " Jasper " Holmes (April 4, 1900 – January 7, 1986) was a US Naval officer, one of the Station HYPO staff, who had the idea of faking a water supply failure on Midway Island in 1942. He suggested using an unencrypted emergency warning, in the hope of provoking a Japanese response, thus establishing whether Midway was a target. Born in Stockport, New York , Holmes was the son of Johan Erik Jonasson Holmes,

325-459: A machine on site in Hawaii has long been seen by conspiracy theorists as a reason for US unpreparedness in Hawaii, and/or to be evidence of a conspiracy by high level officials to deprive Pearl Harbor of intelligence known to Washington. However, no hard evidence for any such conspiracy exists. HYPO was assigned responsibility for work on Japanese Navy systems, and after an agreement with Australia ,
390-556: A new offensive operation being planned against a target only identified as AF. LCDR Wilfred J. Holmes at HYPO was responsible for the ruse which identified AF: a false report of a fresh water shortage on Midway was radioed in clear , evoking an encrypted Japanese response noting that AF was reporting water troubles; AF had to be Midway. As mid-1942 approached, HYPO was under high pressure, and there are tales of 36-hour stints, of Rochefort working in his bathrobe and appearing for briefings late and disheveled besides. This effort climaxed in
455-409: A prior passing encounter, and non-support from his immediate supervisors, led King to deny the award. Nimitz, when he learned of Rochefort's treatment some years later, was quite displeased. Rochefort was posthumously awarded the medal after a campaign by his intelligence officers galvanized Admiral D. "Mac" Showers and eventually CIA head William Casey to rectify the oversight. Having commandeered
520-503: A total volume of 26.5 cubic miles (110 km ) at mean high water. The average volume of water flowing in and out of Puget Sound during each tide is 1.26 cubic miles (5.3 km ). The maximum tidal currents, in the range of 9 to 10 knots , occurs at Deception Pass. Water flow through Deception Pass is approximately equal to 2% of the total tidal exchange between Puget Sound and the Strait of Juan de Fuca. The size of Puget Sound's watershed
585-590: Is 12,138 sq mi (31,440 km ). "Northern Puget Sound" is frequently considered part of the Puget Sound watershed, which enlarges its size to 13,700 sq mi (35,000 km ). The USGS uses the name "Puget Sound" for its hydrologic unit subregion 1711, which includes areas draining to Puget Sound proper as well as the Strait of Juan de Fuca, the Strait of Georgia, and the Fraser River . Significant rivers that drain to "Northern Puget Sound" include

Because of this population decline, there have been changes to the fishery practices, and an increase in petitioning to add species to the Endangered Species Act . There has also been an increase in recovery and management plans for many different area species. The causes of these environmental issues are toxic contamination, eutrophication (low oxygen due to excess nutrients), and near shore habitat changes. On May 22, 1978,

Furthermore, decrypts from PURPLE, eventually called MAGIC , were poorly distributed and used in Washington. SIS was able to build several PURPLE machine equivalents. One was sent to CAST, but as HYPO's assigned responsibility did not include PURPLE traffic, no PURPLE machine was ever sent there. The absence of such
845-656: The Kitsap Peninsula , Whidbey Basin, east of Whidbey Island, South Sound , south of the Tacoma Narrows , and the Main Basin , which is further subdivided into Admiralty Inlet and the Central Basin. Puget Sound's sills, a kind of submarine terminal moraine , separate the basins from one another, and Puget Sound from the Strait of Juan de Fuca. Three sills are particularly significant—the one at Admiralty Inlet which checks

Continuing to work at Station HYPO, Holmes was promoted to commander on May 8, 1943, and then to captain on December 19, 1944. Holmes became chairman of the department of engineering and mathematics at the University of Hawaii after the war, then Dean of Engineering, Dean of Administration, and Vice President, retiring from
1625-530: The Japanese had made use of the idea from "Rendezvous" when planning the operation. Holmes retired from the Navy in 1936 because of arthritis of the spine, and joined the faculty of the University of Hawaii. In 1941, Lieutenant Holmes was recalled to duty and assigned to Station HYPO , which was breaking Japanese codes, especially their naval cipher JN-25 . He was promoted to lieutenant commander on February 25, 1942. By May 1942, US Naval Intelligence knew that

Holmes had the idea of faking a water supply failure on Midway. He suggested using an unencrypted emergency warning, in the hope of provoking a Japanese response, thus establishing whether AF was Midway. Holmes' ruse worked and led to

It is defined as bounded to the north by the international boundary with Canada, and to the west by a line running north from the mouth of the Sekiu River on the Olympic Peninsula. Under this definition, significant parts of the Strait of Juan de Fuca and the Strait of Georgia are included in Puget Sound, with
2340-528: The United States, which both claimed the Oregon Country , agreed to "joint occupancy", deferring resolution of the Oregon boundary dispute until the 1846 Oregon Treaty . Puget Sound was part of the disputed region until 1846, after which it became US territory. American maritime fur traders visited Puget Sound in the early 19th century. An Hudson's Bay Company expedition led by James McMillan in late 1824
2405-571: The Vashon glacier receded a series of proglacial lakes formed, filling the main trough of Puget Sound and inundating the southern lowlands. Glacial Lake Russell was the first such large recessional lake. From the vicinity of Seattle in the north the lake extended south to the Black Hills , where it drained south into the Chehalis River . Sediments from Lake Russell form the blue-gray clay identified as
2470-584: The Vashon ice sheet extended south of Olympia to near Tenino , and covered the lowlands between the Olympic and Cascade mountain ranges. About 14,000 years ago the ice began to retreat. By 11,000 years ago it survived only north of the Canada–US border. The melting retreat of the Vashon Glaciation eroded the land, creating a drumlin field of hundreds of aligned drumlin hills. Lake Washington and Lake Sammamish (which are ribbon lakes ), Hood Canal , and

Sometimes the terms "Puget Sound" and "Puget Sound and adjacent waters" are used for not only Puget Sound proper but also for waters to the north, such as Bellingham Bay and the San Juan Islands region. The term "Puget Sound" is used not just for the body of water but also the Puget Sound region centered on

Other sills that present less of a barrier include the ones at Blake Island , Agate Pass , Rich Passage , and Hammersley Inlet . The depth of the basins is a result of
2795-529: The former, "Rendezvous", imagined an air raid in which flying boats were refueled by submarines at a Pacific atoll, allowing them to reach targets which would normally be well outside their range. This scenario later played out in real life in the form of Operation K , a March 1942 attack by Japanese H8Ks on Pearl Harbor. Unlike the massive carrier-based surprise attack three months earlier, this only involved two aircraft and failed due to bad weather. Naval Intelligence chief Edwin T. Layton later concluded that
2860-740: The fracturing of stressed oceanic rocks as they are subducted, still cause great damage. The Seattle Fault cuts across Puget Sound, crossing the southern tip of Bainbridge Island and under Elliott Bay . To the south, the existence of a second fault, the Tacoma Fault , has buckled the intervening strata in the Seattle Uplift. Typical Puget Sound profiles of dense glacial till overlying permeable glacial outwash of gravels above an impermeable bed of silty clay may become unstable after periods of unusually wet weather and slump in landslides. The United States Geological Survey (USGS) defines Puget Sound as
2925-459: The glacier, their embedded gravels and boulders were deposited in the chaotic mix of unsorted till geologists call glaciomarine drift. Many beaches about the Sound display glacial erratics , rendered more prominent than those in coastal woodland solely by their exposed position; submerged glacial erratics sometimes cause hazards to navigation. The sheer weight of glacial-age ice depressed the landforms, which experienced post-glacial rebound after
2990-433: The ice sheets had retreated. Because the rate of rebound was not synchronous with the post-ice age rise in sea levels, the bed of what is now Puget Sound filled alternately with fresh and with sea water. The upper level of the lake-sediment Lawton Clay now lies about 120 feet (37 m) above sea level. The Puget Sound system consists of four deep basins connected by shallower sills. The four basins are Hood Canal , west of

According to Arthur Kruckeberg, the term "Puget Sound" is sometimes used for waters north of Admiralty Inlet and Deception Pass, especially for areas along the north coast of Washington and the San Juan Islands, essentially equivalent to NOAA's "Northern Puget Sound" subdivision described above. Kruckeberg uses the term "Puget Sound and adjacent waters". Kruckeberg's 1991 text, however, does not reflect

This allowed Admiral Nimitz to gamble on the ambush that resulted in the Battle of Midway , the loss of four Japanese carriers and many naval aviators for much lower Allied losses, and what is generally agreed to have been the turning point of the Pacific War. In October 1942, after Midway, power struggles within

Wilford in his Decoding Pearl Harbor: USN Cryptanalysis and the Challenge of JN-25B in 1941, suggests that this view is now untenable and that the JN-25 codes were readable to a great extent and hence, lends "support to the revisionist theories of Toland and Stinnett". After the attack on Pearl Harbor, there was considerably more JN-25 traffic as the Japanese Navy operational tempo increased and geographically expanded, which helped progress against it. Hong Kong's contribution stopped until
3250-540: The main Puget Sound basin were altered by glacial forces. These glacial forces are not specifically "carving", as in cutting into the landscape via the mechanics of ice/glaciers, but rather eroding the landscape from melt water of the Vashon Glacier creating the drumlin field. As the ice retreated, vast amounts of glacial till were deposited throughout the Puget Sound region. The soils of the region, less than ten thousand years old, are still characterized as immature. As
3315-1265: The marine mammals species found in Puget Sound are harbor seals ( Phoca vitulina ). Orca ( Orcinus orca ), or "killer whales" are famous throughout the Sound, and are a large tourist attraction. Although orca are sometimes seen in Puget Sound proper they are far more prevalent around the San Juan Islands north of Puget Sound. Many fish species occur in Puget Sound. The various salmonid species, including salmon , trout , and char are particularly well-known and studied. Salmonid species of Puget Sound include chinook salmon ( Oncorhynchus tshawytscha ), chum salmon ( O. keta ), coho salmon ( O. kisutch ), pink salmon ( O. gorbuscha ), sockeye salmon ( O. nerka ), sea-run coastal cutthroat trout ( O. clarki clarki ), steelhead ( O. mykiss irideus ), sea-run bull trout ( Salvelinus confluentus ), and Dolly Varden trout ( Salvelinus malma malma ). Common forage fishes found in Puget Sound include Pacific herring ( Clupea pallasii ), surf smelt ( Hypomesus pretiosus ), and Pacific sand lance ( Ammodytes hexapterus ). Important benthopelagic fish of Puget Sound include North Pacific hake ( Merluccius productus ), Pacific cod ( Gadus macrocelhalus ), walleye pollock ( Theragra chalcogramma ), and
