Currents, Gyres, & Eddies - Woods Hole Oceanographic Institution
2024年6月10日 · Eddies are smaller, temporary loops of swirling water that can travel long distances before dissipating. Wind, Currents and Coriolis Wind is the primary force that creates and moves surface currents; Earth's rotation plays an important role in …
ticyclonic eddies to be an important dynamical feature of the halocline. This is the first study of eddies in the central Canada Basin that extends as far north as 79°N, and it reveals shallower eddies likely having different origins than the more southern eddies of past studies. The eddies are characterized by local minima in tem-

The Oceans Have Their Own Weather Systems
2006年4月13日 · The Eddies Dynamics, Mixing, Export, and Species composition (EDDIES) project was born. Into the eye of the oceanic storm “Dennis has wanted to do this experiment since he was a graduate student,” said Dave Siegel, a longtime collaborator with McGillicuddy and an oceanographer from the University of California, Santa Barbara (UCSB).
Five big discoveries from WHOI’s Ocean Twilight Zone Project
2024年5月16日 · Eddies—circular currents the size of a city—regularly develop in ocean waters around the globe. The oceanic equivalent of an atmospheric storm, eddies of warm water provide pathways for large ocean predators to reach the twilight zone. Sharks, tuna, and other fish use their environment to regulate body temperature, which limits their ...
A Warm Eddy Swirling in the Cold Labrador Sea
2007年9月24日 · Eddies can maintain their integrity for long distances—in this case, carrying cargoes of warm water from a warm current flowing around Greenland into the cold Labrador Sea. We know very little about these eddies, but we think they play an important role in the circulation of the Labrador Sea, and perhaps the whole Atlantic Ocean.

The number of eddies with reliable physical property estimates was sufficient to generate meaningful statistics of eddy size, strength, and vertical structure . The majority of center depths were between 90 and 160~m and the mean vertical extent was 130~m. Thus, eddies were found predominantly within the cold halocline.
Gulf Stream eddies that this same air-sea interaction also occurs over mesoscale eddies in association with eddy-induced perturbations of the SST field. In a companion paper, we show that SST-induced Ekman pumping occurs globally within mesoscale eddies but that this SST influence is usually secondary to the effects of surface currents on ...
The trajectories of mesoscale eddies ( 18)in the SEP are shown in Fig. 1A. Compared with eddies observed globally in the latitude range 15° to 25°, their mean amplitude is smaller (3.2 cm versus 6.2 cm) but their mean radius is the same (110 km). Because U is approximately propor-tional to eddy amplitude, eddies in the SEP are
Eddies Found to be Deep, Powerful Modes of Ocean Transport
2011年4月28日 · Researchers from Woods Hole Oceanographic Institution (WHOI) and their colleagues have discovered that massive, swirling ocean eddies known to be up to 500 kilometers across at the surface can reach all the way to the ocean bottom at mid-ocean ridges, some 2,500 meters deep, transporting tiny sea creatures, chemicals, and heat from…
