The Weddell Gyre heat budget associated with the Warm Deep Water circulation derived from Argo floats Open
The Weddell Gyre plays an important role in the global climate system by supplying heat to underneath the ice shelves and in the formation of deep and bottom water masses, which have been subject to widespread warming over past decades. In…

The Weddell Gyre: what drives a long-term increase in surface nutrients? Open
The Weddell Gyre plays a role in connecting the deep ocean to the surface through upwelling, and also in feeding heat towards the Antarctic ice shelves, regulating the density of water masses that feed the deepest limb of the global overtu…

How does the Weddell Gyre circulation influence long-term trends in nutrient concentrations? Open
<p>The large-scale mean horizontal circulation of the Weddell Gyre was determined solely from Argo floats drifting throughout the gyre since 2002. The circulation describes an elongated, double-celled gyre, where the eastern sub-gyre…

Coherent Seasonal Acceleration of the Weddell Sea Boundary Current System Driven by Upstream Winds Open
The Weddell Sea is of global importance in the formation of dense bottom waters associated with sea ice formation and ocean‐ice sheet interaction occurring on the shelf areas. In this context, the Weddell Sea boundary current system (BCS) …

Multidecadal Warming and Density Loss in the Deep Weddell Sea, Antarctica Open
The World Ocean is estimated to store more than 90% of the excess energy resulting from man-made greenhouse gas–driven radiative forcing as heat. Uncertainties of this estimate are related to undersampling of the subpolar and polar regions…

High Resolution Water Column Phytoplankton Composition Across the Atlantic Ocean From Ship-Towed Vertical Undulating Radiometry Open
Different phytoplankton groups dominate ocean biomes and they drive differently the marine food web and the biogeochemical cycles. However, their distribution over most parts of the global ocean remains uncertain due to limitations in the …

The horizontal circulation, upwelling and heat budget of the Weddell Gyre: an observation perspective Open
<p>The Weddell Gyre is an important region in that it feeds source water masses (and thus heat) toward the ice-shelves, and exports locally and remotely formed dense water masses to the global abyssal ocean. Argo float profiles and t…

High-resolution physical–biogeochemical structure of a filament and an eddy of upwelled water off northwest Africa Open
Nutrient-rich water upwells offshore of northwest Africa and is subsequently advected westwards. There it forms eddies and filaments with a rich spatial structure of physical and biological/biogeochemical properties. Here we present a high…

The Weddell Gyre, Southern Ocean: Present Knowledge and Future Challenges Open
The Weddell Gyre (WG) is one of the main oceanographic features of the Southern Ocean south of the Antarctic Circumpolar Current which plays an influential role in global ocean circulation as well as gas exchange with the atmosphere. We re…

On the Reliability of Surface Current Measurements by X-Band Marine Radar Open
Real-time quality-controlled surface current data derived from X-Band marine radar (MR) measurements were evaluated to estimate their operational reliability. The presented data were acquired by the standard commercial off-the-shelf MR-bas…

Horizontal circulation and volume transports in the Weddell Gyre derived from Argo float data Open
Argo floats provide both hydrographic and trajectory data, affording the opportunity to investigate surface to mid-depth ocean dynamics. Here, Argo float data are used to determine the absolute geostrophic velocity field of the upper 50–20…

Cyclonic eddies and upper thermocline fine-scale structures in the Antarctic Circumpolar Current Open
Mesoscale eddies in the open ocean are mostly formed by baroclinic instability, in which the available potential energy from the large-scale slope of the isopycnals is converted into the kinetic energy of the flow around the eddy. As a per…
