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.

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 detrital mixers: U–Pb and Lu–Hf detrital zircon provenance of the Pleistocene–Holocene Bering Sea and its margins

Depositional Record, 2022
Continental shelves serve as critical transfer zones in sediment routing systems, linking the terrestrial erosional and deep‐water depositional domains.

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).

Growth of Continental Shelves at Salt Margins

Frontiers in Earth Science, 2018
Whereas, salt margins are rather common, the growth of continental shelves on top of salt margins is a topic that has seldom been considered. In such settings, the sediments coming from the nearby continental areas are deposited on a viscous substratum ...

Oceanic Routing of Wind-Sourced Energy Along the Arctic Continental Shelves

Frontiers in Marine Science, 2020
Data from coastal tide gauges, oceanographic moorings, and a numerical model show that Arctic storm surges force continental shelf waves (CSWs) that dynamically link the circumpolar Arctic continental shelf system. These trains of barotropic disturbances

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

Diversity and ecological potential of sediment viruses from Chinese continental shelf seas [PDF]

npj Biofilms and Microbiomes
Continental shelves are important areas for global biogeochemical cycling, yet the roles of sediment viruses in these areas remain poorly understood. Here, 48 surface sediment samples from the Chinese continental shelf were analyzed, and 12,540 viral ...
