The Satellite Passive-Microwave Record of Sea Ice in the Ross Sea Since Late 1978 [PDF]

, 2009
Satellites have provided us with a remarkable ability to monitor many aspects of the globe day-in and day-out and sea ice is one of numerous variables that by now have quite substantial satellite records.

Sea-ice production and air/ice/ocean/biogeochemistry interactions in the Ross Sea during the PIPERS 2017 autumn field campaign

Annals of Glaciology, 2020
The Ross Sea is known for showing the greatest sea-ice increase, as observed globally, particularly from 1979 to 2015. However, corresponding changes in sea-ice thickness and production in the Ross Sea are not known, nor how these changes have impacted ...

An Unprecedented Sea Ice Retreat in the Weddell Sea Driving an Overall Decrease of the Antarctic Sea‐Ice Extent Over the 20th Century

Geophysical Research Letters, 2023
Sea‐ice extent is predicted to decrease in a warming climate. However, despite global warming over the past century, total Antarctic sea ice remained relatively stable from 1979 until 2015, before strongly melting.

Energetic plumes over the western Ross Sea continental slope [PDF]

, 2004
Rapid descent of dense Drygalski Trough (western Ross Sea, Antarctica) shelf water over the continental slope, within 100 to 250 m thick benthic plumes, is described. Speeds of up to 1.0 m/s are recorded flowing at an average angle of 35° to the isobaths,

Persistent organic pollutants (POPs) at Ross Sea (Antarctica) [PDF]

Microchemical Journal, 2009
The most significant findings on the presence of persistent organic pollutants (POPs) in the marine ecosystem at Ross Sea are presented. Seawater samples were collected in many sampling sites located in a large area of the Ross Sea during various Italian expeditions in Antarctica.

Impact of Ross Gyre on surface circulation in the Amundsen Sea, Antarctica

Environmental Research Communications
The east limb of the Ross Gyre approaches the western Amundsen Sea, thereby exerting an influence on the surface circulation dynamics. This study investigates the impact of the zonal movement of the eastern boundary of the Ross Gyre on the surrounding ...

Sea ice and the ocean mixed layer over the Antarctic shelf seas [PDF]

, 2013
An ocean mixed-layer model has been incorporated into the Los Alamos sea ice model CICE to investigate regional variations in the surface-driven formation of Antarctic shelf waters.

M₂ tidal dynamics in the Ross Sea [PDF]

Antarctic Science, 2003
In certain regions of the Southern Ocean, tidal energy is believed to foster the mixing of different water masses, which eventually contribute to the formation of deep and bottom waters. The Ross Sea is one of the major ventilation sites of the global ocean abyss and a region of sparse tidal observations.

Reversal of Ross Sea shelf water freshening is linked to a persistent decline in Antarctic sea ice since the mid-2010s

Environmental Research Letters
Since the mid-2010s, a sharp rebound in dense shelf water (DSW) salinity has been observed in the Ross Sea, coinciding with a persistent decline in sea ice around Antarctica. Despite extensive scientific study and significant attention given to these two

New data on Weddell seal (Leptonychotes weddellii) colonies: A genetic analysis of a top predator from the Ross Sea, Antarctica.

PLoS ONE, 2017
In this paper, we studied the genetic variability in Weddell seal from colonies in Terra Nova Bay and Wood Bay, both sites located in the Ross Sea area, Antarctica.
