The Deep‐Water Plume in the Northwestern Weddell Sea, Antarctica: Mean State, Seasonal Cycle and Interannual Variability Influenced by Climate Modes Open
We provide an updated estimate of the annual‐mean, seasonal cycle and interannual variability of the transports and properties of the Weddell Sea Bottom Water (WSBW) plume in the northwestern Weddell Sea. For this we used a densely instrum…

Direct measurements of heat and mass transports through Fram Strait Open
To determine volume and heat transports through Fram Strait, an array of current meter moorings was maintained in the Strait between 1997 and 2001, with annual redeployments. The transports obtained by averaging the monthly means from the …

The influence of tides on the marine carbonate chemistry of a coastal polynya in the south-eastern Weddell Sea Open
Tides significantly affect polar coastlines by modulating ice shelf melt and modifying shelf water properties through transport and mixing. However, the effect of tides on the marine carbonate chemistry in such regions, especially around A…

The role of tides on the carbonate chemistry of a coastal polynya in the south-eastern Weddell Sea Open
<p>Tides have a large impact on coastal polynyas around Antarctica. We investigate the effect of semi-diurnal tidal cycles on the seawater carbonate chemistry in a coastal polynya hugging the Ekstr&#246;m Ice Shelf in the south-e…

Continuous thermosalinograph oceanography along Heincke cruise HE547 Open
Data obtained by a thermosalinograph (SBE21, SeaBird GmbH) and an external temperature sensor (SBE38, Sea-Bird GmbH) were processed to receive a validated data set of temperature and salinity on board RV Heincke during cruise HE547. Unvali…

FISP/FISS Filcher Ronne Ice Shelf cavity (Southern Weddell Sea, Antartcica) oceanographic mooring and ice shelf basal melt rate radar data from 2015 to 2019, processed and low-pass filtered Open
Time series of multi-annual (2015-2019) in-situ measurements of ocean hydrography (temperature, salinity) and ocean current velocities from five hot-water borehole deployed moorings inside the Filchner Ronne Ice Shelf cavity (Southern Wedd…

Continuous thermosalinograph oceanography along RV POLARSTERN cruise track PS122/1 Open
Raw data acquired by two thermosalinographs (SBE21, SeaBird GmbH) on board RV Polarstern were processed to yield a calibrated and validated data set of temperature, conductivity and salinity during expedition PS122/1. Both sensors were equ…

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…
