Record-high Arctic freshwater marine environment Atlantic Ocean currents
2021/3/19
Freshwater is accumulating in the Arctic Ocean. The Beaufort Sea, which is the largest Arctic Ocean freshwater reservoir, has increased its freshwater content by 40% over the past two decades. How and...

Scientists investigate marine heatwaves shifting ocean currents
2020/10/10
North America experienced a series of dangerous heatwaves during the summer of 2020, breaking records from coast to coast.In the ocean, extreme warming conditions are also becoming more frequent and i...

2019/10/28
A new study by NSF-funded scientists at the Woods Hole Oceanographic Institution clarifies the influence of major currents in the North Atlantic Ocean on sea level along the coast of the northeastern ...
Mapping Surface Currents in Monterey Bay With CODAR-Type HF Radar
Mapping Surface Currents Monterey Bay CODAR-Type HF Radar
2015/8/10
High-frequency (HF) radar measurements have been employed around Monterey Bay, CA, to measure ocean surface currents since February 1992. The first array consisted of two older-generation CODAR instru...
The Coastal Jet:Observations of Surface Currents Over the Oregon Continental Shelf From HF Radar
Coastal Jet Surface Currents Oregon Continental Shelf HF Radar
2015/8/10
The ocean circulation over the Oregon shelf during spring and summer is dominated by the effects of coastal upwelling. Equatorward winds drive an offshore Ekman transport in the surface layer, which p...
Internal Wave-Driven Surface Currents From HF Radar
Internal Wave-Driven Surface Currents HF Radar
2015/8/10
Surface current observations from high-frequency (HF) radar have revealed that not only are the low-frequency and tidal currents resolved by the measurement, higher-frequency motions are also containe...
Two important aspects of tidal currents are (1) their temporal coherence and (2) their constancy (over centuries). The first rigorous evaluation of an Ocean Surface Current Radar (OSCR) system exploit...
Shipboard Deployment of a VHF OSCR System for Measuring Offshore Currents
Shipboard Deploymen VHF OSCR System Measuring Offshore Currents
2015/8/10
In July 1994, an OSCR unit was deployed aboard the R/V Columbus Iselin to explore the feasibility of obtaining offshore, vector surface currents from a single platform. The concept is straightforward....
Satellites Reveal the Influence of Equatorial Currents and Tropical Instability Waves on the Drift of the Kon-Tiki in the Pacific
Equatorial Currents Tropical Instability Waves
2015/7/29
A raft drifting on the ocean is at the mercy of the elements. When a sailor describes this experience, one begins to understand the meaning of "in situ," of being in touch with the water. The senses f...
Currents, Eddies, and a "Fish Story" in the Southwestern Japan/East Sea
East Sea Fish Story
2015/7/24
As part of the Japan/East Sea (JES) initiative supported by the U.S. Office of Naval Research, we conducted an observational experiment to understand the physics of the mesoscale circulation in the Ul...
Currents Through the Korea/Tsushima Strait: A Review of LINKS Observations
LINKS Observations Tsushima
2015/7/24
The Korea/Tsushima, Tsugaru, Soya, and Tatar Straits connect the Japan/East Sea (JES) with adjacent seas. Of the four straits, the Korea/Tsushima Strait (KTS) provides the vast majority of inflow into...
A Laboratory Demonstration of Coriolis Effects on Wind-Driven Ocean Currents
Wind-Driven Ocean Currents Coriolis Effects
2015/7/20
Here we study the mechanism by which the wind drives ocean circulation. We induce cyclonic and anticyclonic circulation by blowing air over the surface of a rotating tank of water using fans co-rotati...
Mediterranean Surface Currents Measured with Drifters: From Basin to Subinertial Scales
Surface Currents Measured Subinertial Scales
2015/7/16
Drifter observations in the Mediterranean Sea between 1986 and 2012 have allowed study of important aspects of the surface dynamics in most areas of this marginal sea, including: interannual and seaso...

drifter buoys Lagrangian trajectory applications ocean circulation and dynamics
2014/4/1
Surface currents in oceanic environments are of crucial importance because they transport momentum, heat, salt, and tracers over large distances that regulate both the local and large-scale climate co...
