Direct interaction between the Gulf Stream and the shelfbreak south of New England
(Nature Publishing Group, 2012-08-02)
Sea surface temperature imagery, satellite altimetry, and a surface drifter track reveal an unusual tilt in the Gulf Stream path that brought the Gulf Stream to 39.9°N near the Middle Atlantic Bight shelfbreak—200 km north ...
Expectation-maximization analysis of spatial time series
(Copernicus Publications on behalf of the European Geosciences Union and the American Geophysical Union, 2007-02-01)
Expectation maximization (EM) is used to estimate the parameters of a Gaussian Mixture Model for spatial time series data. The method is presented as an alternative and complement to Empirical Orthogonal Function (EOF) ...
South China Sea hydrological changes and Pacific Walker Circulation variations over the last millennium
(Nature Publishing Group, 2011-04-26)
The relative importance of north–south migrations of the intertropical convergence zone (ITCZ) versus El Niño-Southern Oscillation and its associated Pacific Walker Circulation (PWC) variability for past hydrological change ...

Sound Cut, Record Number 84020001
(Woods Hole Oceanographic Institution, 1994-07-12)
Recording of 5 sperm whales made by Ithaco 602M108 hydrophones, Ithaco 450 amplifiers, WHOI/PEMTEK tape recorders. E Array recording, cow and small calf in the area.
A 2-D tomographic model of the Juan de Fuca plate from accretion at axial seamount to subduction at the Cascadia margin from an active source ocean bottom seismometer survey
(John Wiley & Sons, 2016-08-14)
We report results from a wide-angle controlled source seismic experiment across the Juan de Fuca plate designed to investigate the evolution of the plate from accretion at the Juan de Fuca ridge to subduction at the Cascadia ...
Frequency-dependent two-sex models : a new approach to sex ratio evolution with multiple maternal conditions
(John Wiley & Sons, 2016-09-07)
Mothers that experience different individual or environmental conditions may produce different proportions of male to female offspring. The Trivers-Willard hypothesis, for instance, suggests that mothers with different ...
Experimental evidence for melt partitioning between olivine and orthopyroxene in partially molten harzburgite
(John Wiley & Sons, 2016-08-31)
Observations of dunite channels in ophiolites and uranium series disequilibria in mid-ocean ridge basalt suggest that melt transport in the upper mantle beneath mid-ocean ridges is strongly channelized. We present experimental ...
Short-term dispersal of Fukushima-derived radionuclides off Japan : modeling efforts and model-data intercomparison
(Copernicus Publications on behalf of the European Geosciences Union, 2013-07-24)
The Great East Japan Earthquake and tsunami that caused a loss of power at the Fukushima nuclear power plants (FNPP) resulted in emission of radioactive isotopes into the atmosphere and the ocean. In June of 2011, an ...
Climate forcing for dynamics of dissolved inorganic nutrients at Palmer Station, Antarctica : an interdecadal (1993–2013) analysis
(John Wiley & Sons, 2016-09-17)
We analyzed 20 years (1993–2013) of observations of dissolved inorganic macronutrients (nitrate, N; phosphate, P; and silicate, Si) and chlorophyll a (Chl) at Palmer Station, Antarctica (64.8°S, 64.1°W) to elucidate how ...
