Climate change has had profound effects upon marine ecosystems, impacting across all trophic levels from plankton to apex predators. Determining the impacts of climate change on marine ecosystems requires understanding the direct effects on all trophic levels as well as indirect effects mediated by trophic coupling. The aim of this study was to investigate the effects of climate change on the p...

Abstract The near-bottom mixing that allows abyssal waters to upwell tilts isopycnals and spins up flow over the flanks of mid-ocean ridges. Meso- large-scale currents along sloping topography are subjected a delicate balance Ekman arrest spin down. These two seemingly disparate oceanographic phenomena share common theory, which is based on one-dimensional model rotating, stratified sloping, in...

Signal transmission loss and spatial coherence data for source-receiver separations between 100 and 250 km were acquired in the Gulf of Mexico with a calibrated seismic measurement system (400 m deep), a towed projector (100 m deep) which emitted 67 and 173 Hz tones, and a moored Webb sound source at 988 m depth driven at 175 Hz. Environmental data such as the range dependent bathymetry and sou...

More than 100 circular, elongate or crescent-shaped very large seafloor depressions were found on the southern Namibian continental margin in water depths between 900 and 1700 m. These show extraordinary sizes of up to 3 km diameter 180 m depth. Multichannel seismic bathymetric data influence bottom currents their morphology through prograding infills upcurrent erosion downcurrent flanks, thus ...

in the nighttime, drainage flow occurs along the basin sideslope and advects cold air to the boundary layer over the basin bottom (bbl), intensifying the cooling rate of the layer. a nocturnal cold air lake develops in the basin, attaining a depth nearly equal to the topographical depth of the basin. heat budget analysis of the whole basin surface shows that net radiative flux closely balances ...
