Moored observations of shelfbreak processes at the inflow to and outflow from the Arctic Ocean
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2013-02)
Two high-resolution mooring arrays extending from the outer shelf to the mid continental slope are used to elucidate shelf-basin exchange at the inflow to and the outflow from the Arctic Ocean. Pacific Water entering the ...
Internal waves and turbulence in the Antarctic Circumpolar Current
(American Meteorological Society, 2013-02)
This study reports on observations of turbulent dissipation and internal wave-scale flow properties in a standing meander of the Antarctic Circumpolar Current (ACC) north of the Kerguelen Plateau. The authors characterize ...
Measurements of shoaling internal waves and turbulence in an estuary
(John Wiley & Sons, 2013-01-30)
The shoaling of horizontally propagating internal waves may represent an important source of mixing and transport in estuaries and coastal seas. Including such effects in numerical models demands improvements in the ...
Turbulence and diapycnal mixing in Drake Passage
(American Meteorological Society, 2012-12)
Direct measurements of turbulence levels in the Drake Passage region of the Southern Ocean show a marked enhancement over the Phoenix Ridge. At this site, the Antarctic Circumpolar Current (ACC) is constricted in its flow ...
Horizontal scales of variability over the Middle Atlantic Bight shelf break and continental rise from finescale observations
(American Meteorological Society, 2013-01)
Observations with fine horizontal resolution are used to identify the horizontal scales of variability over the Middle Atlantic Bight (MAB) shelf break and continental rise. Spray gliders collected observations along two ...
Constraining the North Atlantic circulation with transient tracer observations
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2003-02)
The capability of transient tracers to constrain the ocean circulation in the North Atlantic is explored. Study of an idealized tracer shows that inferences of circulation properties from transient state distributions ...
Is biological productivity enhanced at the New England shelfbreak front?
(John Wiley & Sons, 2013-01-31)
A two-dimensional (cross-shelf) numerical model of the mean seasonal circulation offshore of southern New England predicts upwelling at the shelfbreak front. Expected ramifications of this upwelling include enhancement of ...
Local and remote wind stress forcing of the seasonal variability of the Atlantic Meridional Overturning Circulation (AMOC) transport at 26.5°N
(John Wiley & Sons, 2015-04-02)
The transport of the Atlantic Meridional Overturning Circulation (AMOC) varies considerably on the seasonal time scale at 26.5°N, according to observations made at the RAPID-MOCHA array. Previous studies indicate that the ...
Rapid injection of near-inertial shear into the stratified upper ocean at an Antarctic Circumpolar Current front
(John Wiley & Sons, 2015-05-07)
The impact on the upper ocean of the passage of a short, intense storm over a Southern Ocean site, in proximity to an Antarctic Circumpolar Current front, is characterized. The storm causes a wind-induced deepening of the ...
SPURS : Salinity Processes in the Upper-ocean Regional Study— the North Atlantic Experiment
