Jun 10, 2024 · Another subpolar gyre, the only one centered on a landmass, circles Antarctica driven by the near-constant westerly winds that blow over the Southern Ocean, unimpeded by land. Boundary Currents The subtropical gyres are surrounded by four linked currents: two boundary currents oriented roughly north-south at their eastern and western edges and ...

May 8, 2023 · The recent documented state of the gyre “does not represent a return to the initial condition of 2003 when the gyre was weak and located partially in the southeastern basin. Instead, under the strengthened wind stress curl, the gyre has continuously intensified even though it has contracted, and it has maintained its excess freshwater storage ...

Aug 25, 2022 · Le Bras: The gyre sets the ocean temperature and salinity over a large portion of the Arctic, which impacts how the ocean and atmosphere interact with each other. In turn, that influences the overall climate. The Beaufort Gyre also impacts how freshwater moves from place to place within the ocean, which can affect ocean currents across the globe.

Jul 19, 2016 · The gyre corrals this pool of ice and fresh water, preventing it from flowing southward into the North Atlantic Ocean. (Illustration by Eric S. Taylor, Woods Hole Oceanographic Institution) During the low-pressure phase in the Arctic, cyclonic storm systems that form in the North Atlantic move up into the Arctic, bringing heat and moisture.

Feb 21, 2019 · Beaufort Gyre Exploration Project Woods Hole Oceanographic Institution is the world's leading non-profit oceanographic research organization. Our mission is to explore and understand the ocean and to educate scientists, students, decision-makers, and the public.

An important feature of Beaufort Gyre is the low salinity lens that has formed at the surface due to the anticyclonic (clockwise) wind stress on the ocean that drives convergent surface water flow and in turn, the anticyclonic Beaufort Gyre.

Beaufort Gyre Observing System are three deep-ocean bottom-tethered moorings with CTD and velocity profilers, upward looking sonars for ice draft measurements, and bottom pressure recorders. A major goal of this project is to investigate basin-scale mechanisms regulating freshwater and heat content in the Arctic Ocean and particularly

Jan 25, 2006 · The gyre accumulates fresh water created when ice melts. More fresh water drains into it from big northern rivers. Winds typically corral this huge freshwater reservoir, but when they periodically diminish, the gyre weakens, vast volumes of trapped fresh water leak out, and climate conditions shift.

The Beaufort Gyre Freshwater Experiment (BGFE) observational program was designed to measure the freshwater content of the upper ocean and sea ice in the Beaufort Gyre of the Arctic Ocean using bottom-tethered moorings, drifting buoys, and hydrographic stations. The mooring

Jan 8, 2020 · North Pacific Gyre Oscillation (NPGO) One of the most recent oscillations to be described, the North Pacific Gyre Oscillation (NPGO) affects the height of the sea surface in the Northeast Pacific. This, in turn, affects the intensity of the central and eastern branches of the North Pacific gyre—a major ocean circulation pattern in the North ...
