(June - October) A team explored and studied the communities of animals found around deep-sea oil seeps to improve our understanding of the lush habitats that thrive in the absence of sunlight.
(August - September) An international team explored the frigid depths of the remote Canada Basin, located in the Arctic Ocean. Due to the region's heavy year-round ice cover, this expedition was the first one of its kind.
(August - September) An exploration team mapped a significant portion of the slope and rise to the east and west of the Hudson Canyon, off New York and New Jersey.
(September - November) A team of scientists traveled to the Northwestern Hawaiian Islands, a remote chain of small islands and atolls, to view unexplored seamounts and map pristine coral reefs.
(August) Tribal Journeys was an event among many in a cultural resurgence among Northwest Coast Native Americans and First Nations. Staff from NOAA’s Olympic Coast National Marine Sanctuary played a small role in helping and documenting the journey as a gift to the Tribes and Nations.
The Census of Marine Life is an international research effort to assess and explain the diversity, distribution, and abundance of marine organisms throughout the world’s oceans. Read about some of these efforts.
(August) Based on the exciting results of the 2001 mission to Heceta Bank, an exploration team used modern tools to study the submerged ancient shorelines of the U.S. northwest coast.
(July - August) Sustainable Seas was a five-year project of underwater exploration and discovery of the marine world with special emphasis on the national marine sanctuaries of the United States.
Located 20 meters beneath the surface of the Atlantic Ocean, next to deep coral reefs in the Florida Keys, Aquarius is the world’s only undersea laboratory. Read about an essay contest and a Girl Scout project to visit the underwater habitat.
(May - June) Scientists sailed on the French research vessel Le Suroit to deploy six continuously recording hydrophones around the Mid-Atlantic Ridge north of the Azores.
(Spring) The Link Project fostered collaboration between ocean and space scientists and engineers and promoted the benefits to humankind of ocean and space exploration, research, and related technology development.
(April - October) This exploration focused on the mid-summer recovery of the Monitor's engine, a key step toward recovering of the ship's central turret. This is part of a multi-year project designed to preserve this historic Civil War vessel for future generations.
(May - August) Scientists explored coral reef and hard-bottom communities throughout the Gulf of Mexico. A special focus was the effects of currents on the life cycles and migration patterns of various species.
(June - July) A team mapped the Columbia River's offshore canyon and characterized its physical and biological systems. Astoria Canyon, the westernmost portion of the river's drainage system, is a virtually unexplored biological haven.
(August) A team improved our understanding of the sources of ocean noise by installing a vertical hydrophone array off the coast of central California.
(September) A team characterized deep-sea ecosystems from New England to Georgia with a manned submersible. The three target areas included Georges Bank Canyons, Hudson Canyon, and Blake Ridge.
(November) Laser Line Scan (LLS) is an electro-optic imaging technique designed to provide the efficiency and spatial coverage of a remote survey system, at an image resolution approaching that of visual observations. During this exploration, LLS was field tested off the California coast.
(July) The exact location of the lost Navy submarine, USS S-5, was discovered during this exploration.
(June - July) Scientists used an experimental system which was, at the time, one of only three in the world, to characterize very small-scale environments in Alaska.
(June) During this project, scientists used a new side-scan sonar system to identify shipwrecks in the historic area that became the 13th U.S. National Marine Sanctuary. More than 100 vessels are believed to rest here, but only 40 had been located prior to this mission.
