Bottom marine heatwaves along the continental shelves of North America [PDF]

Nature Communications, 2023
The authors investigate marine heatwaves on the ocean bottom in the shallow waters surrounding North America. Relative to their surface counterparts, bottom marine heatwaves are often more intense, more persistent, and can occur independently.

Explicit representation and parametrised impacts of under ice shelf seas in the z^∗ coordinate ocean model NEMO 3.6 [PDF]

Geoscientific Model Development, 2017
Ice-shelf–ocean interactions are a major source of freshwater on the Antarctic continental shelf and have a strong impact on ocean properties, ocean circulation and sea ice.

Large-scale groundwater flow and sedimentary diagenesis in continental shelves influence marine chemical budgets [PDF]

Nature Communications
The major ion chemistry of the ocean has been assumed to be controlled by river input, hydrothermal circulation at mid-ocean ridges, carbonate production, and low-temperature alteration of seafloor basalt, but marine chemical budgets remain difficult to ...

Continental shelves as potential resource of rare earth elements [PDF]

Scientific Reports, 2017
The results of this study allow the reassessment of the rare earth elements (REE) external cycle. Indeed, the river input to the oceans has relatively flat REE patterns without cerium (Ce) anomalies, whereas oceanic REE patterns exhibit strong negative ...

Continental shelves as a variable but increasing global sink for atmospheric carbon dioxide [PDF]

Nature Communications, 2018
It remains unclear whether surface water partial pressure of CO2 (pCO2) in continental shelves tracks with increasing atmospheric pCO2. Here, the authors show that pCO2 in shelf waters lags behind rising atmospheric CO2 in a number of shelf regions ...

Bottom trawl fishing footprints on the world's continental shelves. [PDF]

Proc Natl Acad Sci U S A, 2018
Significance We conducted a systematic, high-resolution analysis of bottom trawl fishing footprints for 24 regions on continental shelves and slopes of five continents and New Zealand. The proportion of seabed trawled varied >200-fold among regions (from 0.4 to 80.7% of area to a depth of 1,000 m).

Influence of the grounding zone on the internal structure of ice shelves [PDF]

Nature Communications
Antarctic ice shelves typically comprise continental meteoric ice, in situ-accumulated meteoric ice, and marine ice accumulated at the shelf base. Using borehole optical televiewer logs from across Larsen C Ice Shelf, Antarctic Peninsula, we identify and

Future Response of Antarctic Continental Shelf Temperatures to Ice Shelf Basal Melting and Calving

Geophysical Research Letters, 2023
We investigate feedbacks between subsurface continental shelf ocean temperatures and Antarctic glacial melt using a coupled climate model. The model was forced with SSP5‐8.5 and an uncoupled projection of basal melt and calving fluxes.

Projected sea level rise on the continental shelves of the China Seas and the dominance of mass contribution

Environmental Research Letters, 2021
We analyze the projected sea level rise (SLR) for the 21st century for the China Seas (the Bohai Sea, Yellow Sea, East China Sea, and South China Sea) using the Coupled Model Intercomparison Project Phase 5 dataset.

Modeling intensive ocean–cryosphere interactions in Lützow-Holm Bay, East Antarctica [PDF]

The Cryosphere, 2021
Basal melting of Antarctic ice shelves accounts for more than half of the mass loss from the Antarctic ice sheet. Many studies have focused on active basal melting at ice shelves in the Amundsen–Bellingshausen seas and the Totten ice shelf, East ...
