The marine geochemistry of the rare earth elements
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1983-09)
Novel methods were developed for the determination of 12 of the 14 Rare Earth Elements (REE) in seawater. Initial extractions of the REE by chelating ion exchange chromatography is followed by cation exchange for removal ...
Mixing variability in the Southern Ocean
(American Meteorological Society, 2015-04)
A key remaining challenge in oceanography is the understanding and parameterization of small-scale mixing. Evidence suggests that topographic features play a significant role in enhancing mixing in the Southern Ocean. This ...
Anomalous porosity preservation and preferential accumulation of gas hydrate in the Andaman accretionary wedge, NGHP-01 site 17A
In addition to well established properties that control the presence or absence of the hydrate stability zone, such as pressure, temperature, and salinity, additional parameters appear to influence the concentration of gas ...
Experimental and numerical studies of sound propagation over a submarine canyon northeast of Taiwan
A study of sound propagation over a submarine canyon northeast of Taiwan was made using mobile acoustic sources during a joint ocean acoustic and physical oceanographic experiment in 2009. The acoustic signal levels ...
Anomalous chlorofluorocarbon uptake by mesoscale eddies in the Drake Passage region
(John Wiley & Sons, 2015-02-23)
The role of mesoscale eddies in the uptake of anthropogenic chlorofluorocarbon-11 (CFC-11) gas is investigated with a 1/20° eddy-resolving numerical ocean model of a region of the Southern Ocean. With a relatively fast ...
Pathways and mechanisms of offshore water intrusions on the Espírito Santo Basin shelf (18°S–22°S, Brazil)
(John Wiley & Sons, 2016-07-30)
The pathways and physical mechanisms associated with intrusions of cold, nutrient-rich South Atlantic Central Water (SACW) on the continental shelf of the Espírito Santo Basin (ESB), off southeast Brazil (18°S–22°S), are ...
Global distribution of the decay timescale of mixed layer inertial motions observed by satellite-tracked drifters
(American Geophysical Union, 2009-11-05)
The decay timescale of mixed layer inertial amplitudes has been estimated from satellite tracked drifter trajectories from 1990 to 2004 as the e-folding timescale of the temporal correlation functions. The decay timescales ...
From salty to fresh—salinity processes in the Upper-ocean Regional Study-2 (SPURS-2) : diagnosing the physics of a rainfall-dominated salinity minimum
(The Oceanography Society, 2015-03)
One of the notable features of the global ocean is that the salinity of the North Atlantic is about 1 psu higher than that of the North Pacific. This contrast is thought to be due to one of the large asymmetries in the ...
Ceratoscopelus maderensis : pecular sound-scattering layer identified with this myctophid fish
(Woods Hole Oceanographic Institution, 1968-10)
A sound- scattering layer, composed of discrete hyperbolic echo-sequences and apparently restricted to the Slope Water region of the western North Atlantic, has been identified from the Deep Submergence Research Vehicle ...
