Kamaʻehuakanaloa Seamount is an active submarine volcano about 22 mi (35 km) off the southeast coast of the island of Hawaii. The top of the seamount is about 3,200 ft (975 m) below sea level. This seamount is on the flank of Mauna Loa, the largest active subaerial shield volcano on Earth. Kamaʻehuakanaloa is the newest volcano in the Hawaiian–Emperor seamount chain, a string of volcanoes that stretches about 3,900 mi (6,200 km) northwest of Kamaʻehuakanaloa. Unlike most active volcanoes in the Pacific Ocean that make up the active plate margins on the Pacific Ring of Fire, Kamaʻehuakanaloa and the other volcanoes of the Hawaiian–Emperor seamount chain are hotspot volcanoes and formed well away from the nearest plate boundary. Volcanoes in the Hawaiian Islands arise from the Hawaii hotspot, and as the youngest volcano in the chain, Kamaʻehuakanaloa is the only Hawaiian volcano in the deep submarine preshield stage of development.
The National Ocean Service (NOS) is an office within the U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA). It is the responsible for preserving and enhancing the nation's coastal resources and ecosystems along approximately 95,000 miles (153,000 km) of shoreline, that is bordering 3,500,000 square miles (9,100,000 km2) of coastal, Great Lakes, and ocean waters. Its mission is to "provide science-based solutions through collaborative partnerships to address the evolving economic, environmental, and social pressures on our oceans and coasts." Its projects focus on working to ensure the safe and efficient marine transportation, promoting the protection of coastal communities, conserving marine and coastal places. NOS employs 1,700 scientists, natural resource managers, and specialists in many different fields. The National Ocean Service was previously also known as the National Ocean Survey until it was renamed in 1983.
Monterey Bay National Marine Sanctuary (MBNMS) is a federally protected marine area offshore of California's Big Sur and central coast in the United States. It is one of the largest US national marine sanctuaries and has a shoreline length of 276 miles (444 km) stretching from just north of the Golden Gate Bridge at San Francisco to Cambria in San Luis Obispo County. Supporting one of the world's most diverse marine ecosystems, it is home to numerous mammals, seabirds, fishes, invertebrates and algae in a remarkably productive coastal environment. MBNMS was designated on September 18, 1992, for the purpose of resource protection, research, education, and compatible public use.
USS Flamingo (AM-32) was a Lapwing-class minesweeper built for the United States Navy near the end of World War I. After service overseas clearing mines after the Armistice, the ship was laid up until 1922 when she was transferred to the United States Department of Commerce for use by the United States Coast and Geodetic Survey. Renamed USC&GS Guide, the ship operated as a survey vessel along the West Coast of the United States for 17 years, making significant contributions to navigation, hydrographic surveying, and oceanography. In June 1941, Guide was transferred back to the Navy, converted into a salvage ship, and renamed USS Viking (ARS-1). As Viking, she worked primarily from bases in California until 1953, when she was sold for scrapping.
Cobb Seamount is a seamount and guyot located 500 km (310 mi) west of Grays Harbor, Washington, United States. Cobb Seamount is one of the seamounts in the Cobb–Eickelberg Seamount chain, a chain of underwater volcanoes created by the Cobb hotspot that terminates near the coast of Alaska. It lies just west of the Cascadia subduction zone, and was discovered in August 1950 by the U.S. Fish and Wildlife Service fisheries research vessel R/V John N. Cobb. By 1967, over 927 km (576 mi) of soundings and dozens of samples from the seamount had been collected.
The Hawaiʻi hotspot is a volcanic hotspot located near the namesake Hawaiian Islands, in the northern Pacific Ocean. One of the best known and intensively studied hotspots in the world, the Hawaii plume is responsible for the creation of the Hawaiian–Emperor seamount chain, a 6,200-kilometer (3,900 mi) mostly undersea volcanic mountain range. Four of these volcanoes are active, two are dormant; more than 123 are extinct, most now preserved as atolls or seamounts. The chain extends from south of the island of Hawaiʻi to the edge of the Aleutian Trench, near the eastern coast of Russia.
Davidson Seamount is a seamount located off the coast of Central California, 80 mi (129 km) southwest of Monterey and 75 mi (121 km) west of San Simeon. At 26 mi (42 km) long and 8 mi (13 km) wide, it is one of the largest known seamounts in the world. From base to crest, the seamount is 7,480 ft (2,280 m) tall, yet its summit is still 4,101 ft (1,250 m) below the sea surface. The seamount is biologically diverse, with 237 species and 27 types of deep-sea coral having been identified.
George Davidson was a geodesist, astronomer, geographer, surveyor and engineer in the United States.
The United States Coast and Geodetic Survey was the first scientific agency of the United States Government. It existed from 1807 to 1970, and throughout its history was responsible for mapping and charting the coast of the United States, and later the coasts of U.S. territories. In 1871, it gained the additional responsibility of surveying the interior of the United States and geodesy became a more important part of its work, leading to it being renamed the U.S. Coast and Geodetic Survey in 1878.
The following outline is provided as an overview of and introduction to Oceanography.
USS Mobjack (AVP-27/AGP-7) was a motor torpedo boat tender in commission in the United States Navy from 1943 to 1946. She saw service in the Pacific theater during the latter portion of World War II.
USC&GS Pioneer was a survey ship that served in the United States Coast and Geodetic Survey from 1922 to 1941. She was the first ship of the Coast and Geodetic Survey to bear the name.
NOAA Ship Surveyor was an oceanographic survey ship in commission in the National Oceanic and Atmospheric Administration (NOAA) from 1970 until 1995. Prior to her NOAA career, she was in commission in the United States Coast and Geodetic Survey from 1960 to 1970 as USC&GS Surveyor. She was the second and last Coast and Geodetic Survey ship named Surveyor and has been the only NOAA ship thus far to bear the name.
The second USC&GS Fathomer was a steamer that served as a survey ship in the United States Coast and Geodetic Survey from 1905 to 1942.
The President Jackson Seamounts are a series of seamounts located on the Pacific Plate, off of California. It consists of 8 seamounts, 4 independent and 4 morpohologically fused, just west of the northern Gorda Ridge. They are generally very small, and arranged linearly.
Patton Seamount is a prominent seamount in the Cobb–Eickelberg Seamount chain in the Gulf of Alaska. Located 166 nmi east of Kodiak Island and reaching to within 160 m (520 ft) of the ocean surface, Patton is one of the largest seamounts in the Cobb–Eickelberg Seamount chain. It was originally created near the coast of Oregon by the Cobb hotspot 33 million years ago and was moved to its present location by tectonic plate movement. Patton is one of the most well-understood seamounts, as a major expedition using DSV Alvin in 1999 and another in 2002 helped define the scope of the seamount's biological community. Like other large seamounts, Patton acts as an ecological hub for sea life. Dives have revealed that the volcano is heavily encrusted in sea life of various forms, including sea stars, corals, king crabs, demersal rockfish, and other species.
The Blake Plateau lies in the western Atlantic Ocean off the coasts of North Carolina, South Carolina, Georgia, and Florida in the southeastern United States. The Blake Plateau lies between the North American continental shelf and the deep ocean basin extending about 145 kilometers east and west by 170 kilometers north and south, with a depth of about 500 meters inshore sloping to about 1,000 meters about 375 kilometers off shore, where the Blake Escarpment drops steeply to the deep basin. The Blake Plateau and the associated Blake Ridge and Blake Basin are named for the United States Coast and Geodetic Survey steamer USC&GS George S. Blake, in service from 1874 to 1905, which was the first ship to use steel cable for oceanographic operations and pioneered deep ocean and Gulf Stream exploration. George S. Blake′s hydrographic survey lines first defined the plateau that now bears the ship's name.
Rear Admiral Harley Dean Nygren was an American military officer who served in the United States Coast and Geodetic Survey Corps, its successor, the Environmental Science Services Administration Corps, and the ESSA Corps's successor, the National Oceanic and Atmospheric Administration Commissioned Officer Corps. He served as the first Director of the NOAA Corps.
