Grounding-zone wedges and mega-scale glacial lineations in the Mertz Trough, East Antarctica
Glacial erosion and deposition have shaped the Mertz Trough, East Antarctica, where seafloor grounding-zone wedges (GZWs) are associated with mega-scale glacial lineations (MSGLs) (McMullen et al. 2006). GZWs form along ...
Sound Cut, Record Number 66038Ahi1_01
(Woods Hole Oceanographic Institution, 2007-08-14)
Recording of unknown number of Bearded seals.
Geomorphology and Neogene tectonic evolution of the Palomares continental margin (Western Mediterranean)
The Palomares continental margin is located in the southeastern part of Spain. The margin main structure was formed during Miocene times, and it is currently part of the wide deformation zone characterizing the region ...
Segment-scale variations in seafloor volcanic and tectonic processes from multibeam sonar imaging, Mid-Atlantic Ridge Rainbow region (35°45′–36°35′N)
(John Wiley & Sons, 2016-09-07)
Along-axis variations in melt supply and thermal structure can lead to significant variations in the mode of crustal accretion at mid-ocean ridges. We examine variations in seafloor volcanic and tectonic processes on the ...
Antarctic intermediate water circulation in the South Atlantic over the past 25,000 years
(John Wiley & Sons, 2016-10-05)
Antarctic Intermediate Water is an essential limb of the Atlantic meridional overturning circulation that redistributes heat and nutrients within the Atlantic Ocean. Existing reconstructions have yielded conflicting results ...
Mesoscale modulation of air-sea CO2 flux in Drake Passage
(John Wiley & Sons, 2016-09-10)
We investigate the role of mesoscale eddies in modulating air-sea CO2 flux and associated biogeochemical fields in Drake Passage using in situ observations and an eddy-resolving numerical model. Both observations and model ...
The Atlantic Water boundary current in the Nansen Basin : transport and mechanisms of lateral exchange
(John Wiley & Sons, 2016-09-22)
Data from a shipboard hydrographic survey near 30°E in the Nansen Basin of the Arctic Ocean are used to investigate the structure and transport of the Atlantic Water boundary current. Two high-resolution synoptic crossings ...
Atmospheric forcing during active convection in the Labrador Sea and its impact on mixed-layer depth
(John Wiley & Sons, 2016-09-22)
Hydrographic data from the Labrador Sea collected in February–March 1997, together with atmospheric reanalysis fields, are used to explore relationships between the air-sea fluxes and the observed mixed-layer depths. The ...
Description of surface transport in the region of the Belizean Barrier Reef based on observations and alternative high-resolution models
The gains from implementing high-resolution versus less costly low-resolution models to describe coastal circulation are not always clear, often lacking statistical evaluation. Here we construct a hierarchy of ocean-atmosphere ...
Fractionation of the methane isotopologues 13CH4, 12CH3D, and 13CH3D during aerobic oxidation of methane by Methylococcus capsulatus (Bath)
Aerobic oxidation of methane plays a major role in reducing the amount of methane emitted to the atmosphere from freshwater and marine settings. We cultured an aerobic methanotroph, Methylococcus capsulatus (Bath) at 30 ...
