Contourites and associated sediments controlled by deep-water circulation processes: State-of-the-art and future considerations
Abstract The contourite paradigm was conceived a few decades ago, yet there remains a need to establish a sound connection between contourite deposits, basin evolution and oceanographic processes.Expand
Inflow of Warm Circumpolar Deep Water in the Central Amundsen Shelf
The thinning and acceleration of the West Antarctic Ice Sheet has been attributed to basal melting induced by intrusions of relatively warm salty water across the continental shelf. A hydrographicExpand
State of the Climate in 2014
Editors note: For easy download the posted pdf of the State of the Climate for 2014 is a very low-resolution file. A high-resolution copy of the report is available by clicking here. Please beExpand
State of the Climate in 2016
In 2016, the dominant greenhouse gases released into Earth's atmosphere-carbon dioxide, methane, and nitrous oxide-continued to increase and reach new record highs. The 3.5 +/- 0.1 ppm rise in globExpand
Persistent inflow of warm water onto the central Amundsen shelf
The West Antarctic Ice Sheet is sensitive to ocean warming and contains enough ice to significantly raise sea level. Direct oceanographic measurements in the Amundsen Sea during 2010 show continuousExpand
Variability of Warm Deep Water Inflow in a Submarine Trough on the Amundsen Sea Shelf
The ice shelves in the Amundsen Sea are thinning rapidly, and the main reason for their decline appears to be warm ocean currents circulating below the ice shelves and melting these from below.Expand
Downward flow of dense water leaning on a submarine ridge
Large-scale dense bottom currents are geostrophic to leading order, with the main flow direction along the continental slope. Bottom friction makes the water descend to greater depths, but only at aExpand
Topographic steering of dense currents with application to submarine canyons
The influence of a submarine canyon on a dense bottom current flowing along the continental shelf is considered. It is shown that the front of the current moves forward with the Nof velocity,Expand
Circulation and Modification of Warm Deep Water on the Central Amundsen Shelf
AbstractThe circulation pathways and subsurface cooling and freshening of warm deep water on the central Amundsen Sea shelf are deduced from hydrographic transects and four subsurface moorings. TheExpand
Influence of the Coriolis force on the velocity structure of gravity currents in straight submarine channel systems
[1] Large-scale turbidity currents in submarine channels often show a significant asymmetry in the heights of their levee banks. In the Northern Hemisphere, there are many observations of theExpand
