Evidence for influx of Atlantic water masses to the Labrador Sea during the Last Glacial Maximum [PDF]

Scientific Reports, 2021
The Last Glacial Maximum (LGM, 23–19,000 year BP) designates a period of extensive glacial extent and very cold conditions on the Northern Hemisphere. The strength of ocean circulation during this period has been highly debated.

Co-ordinated shifts in deep-water formation and Gulf Stream migration during abrupt climate changes [PDF]

Nature Communications
Theory and models suggest the Gulf Stream may shift northwards under projected Atlantic Meridional Overturning Circulation weakening. Yet Gulf Stream behaviour during past abrupt cold events remains poorly constrained.

Atlantic water recirculation in the northern Barents Sea affects winter sea ice extent [PDF]

Nature Communications
Over the past 50 years, Arctic sea ice has declined in all seasons, with particularly pronounced winter reductions in the Barents Sea. While temperature changes in the Atlantic Water inflow and atmospheric-driven melt have been identified as key drivers ...

Mixing and air–sea buoyancy fluxes set the time-mean overturning circulation in the subpolar North Atlantic and Nordic Seas [PDF]

Ocean Science, 2023
The overturning streamfunction as measured at the OSNAP (Overturning in the Subpolar North Atlantic Program) mooring array represents the transformation of warm, salty Atlantic Water into cold, fresh North Atlantic Deep Water (NADW). The magnitude of the

Determination of Recharge Areas That Supply Decades Old Groundwater to Creeks Inhabited by the Threatened Okaloosa Darter

Hydrology, 2022
The Okaloosa darter (Etheostoma okaloosae) is a diminutive, perch-like, benthic fish that inhabits only six small, clear, and shallow creek systems that flow almost entirely within Eglin Air Force Base in the panhandle of northwest Florida.

Feral swine as sources of fecal contamination in recreational waters

Scientific Reports, 2021
Recreational waters are primary attractions at many national and state parks where feral swine populations are established, and thus are possible hotspots for visitor exposure to feral swine contaminants.

Water masses in the Atlantic Ocean: characteristics and distributions [PDF]

Ocean Science, 2021
A large number of water masses are presented in the Atlantic Ocean, and knowledge of their distributions and properties is important for understanding and monitoring of a range of oceanographic phenomena.

Circulation timescales of Atlantic Water in the Arctic Ocean determined from anthropogenic radionuclides [PDF]

Ocean Science, 2021
The inflow of Atlantic Water to the Arctic Ocean is a crucial determinant for the future trajectory of this ocean basin with regard to warming, loss of sea ice, and ocean acidification.

Transport Structure of the South Atlantic Ocean Derived From a High-Resolution Numerical Model and Observations

Frontiers in Marine Science, 2022
The South Atlantic Ocean plays an important role in the Atlantic meridional overturning circulation (AMOC), connecting it to the Indian and Pacific Oceans as part of the global overturning circulation system. Yet, there are still open questions regarding

Is There the Equatorial Water Mass in the Atlantic Ocean?

Geophysical Research Letters, 2023
Using temperature and salinity profiles from the Argo data repository, a detailed volumetric temperature‐salinity diagram is compiled for the upper 2,000 m layer of the Atlantic Ocean.
