Projections of winter polynyas and their biophysical impacts in the Ross Sea Antarctica
This study investigates winter polynyas in the southern Ross Sea, Antarctica where several polynyas are known to form. Coastal polynyas are areas of...

Effect of Mantle Viscosity Structures on Simulations of Geoid Anomalies in the Ross Sea Area
The effect of mantle viscosity structures on numerical simulations of geoid anomalies in the Ross Sea is investigated. Four relatively new S-wave...

Representation of sea ice regimes in the Western Ross Sea, Antarctica, based on satellite imagery and AMPS wind data
Sea ice drift data at high spatial resolution and surface wind model output are used to explore atmosphere-sea ice interactions in the Western Ross...

Gravity data fusion using wavelet transform and window weighting: a case study in the Ross Sea of Antarctica
Satellite gravity anomaly data are characterized with wide coverage and high overall normalized quality, and these data can be used in large-scale...

Bottom Simulating Reflector in the Western Ross Sea, Antarctica
Seismic evidence of gas hydrates and free gas in the western Ross Sea (Antarctica) is inferred from the occurrence of a bottom simulating reflector....
-
The Processes-Based Attributes of Four Major Surface Melting Events over the Antarctic Ross Ice Shelf
The Ross-Amundsen sector is experiencing an accelerating warming trend and a more intensive advective influx of marine air streams. As a result,...

Recent recovery of Antarctic Bottom Water formation in the Ross Sea driven by climate anomalies
Antarctic Bottom Water (AABW) supplies the lower limb of the global overturning circulation, ventilates the abyssal ocean and sequesters heat and...
-
An Amundsen Sea source of decadal temperature changes on the Antarctic continental shelf
Mass loss from the Antarctic Ice Sheet is dominated by basal melting–induced warm ocean water. Ice-sheet mass loss and thinning of buttressing ice...

Weakened relationship between ENSO and Antarctic sea ice in recent decades
The dominant mode of interannual variability in the Antarctic sea ice is presented by a significant seesaw structure with an out-of-phase...

Dynamic linkage between the interannual variability of the spring Ross Ice Shelf Polynya and the atmospheric circulation anomalies
We investigate the spatio-temporal characteristics of the austral spring Ross Ice Shelf Polynya (RISP) and its relationship with atmospheric...

Sea surface temperature anomalies related to the Antarctic sea ice extent variability in the past four decades
The Antarctic sea ice extent, though varying considerably with season and region, had been on a slight increasing trend from late 1970s until...

Spatial variations of authigenic beryllium isotopes in surface sediments of the Antarctic oceans: a proxy for sea ice dynamics and sedimentary environments
This study documents spatial variations in authigenic 9 Be and 10 Be concentrations and 10 Be/ 9 Be ratios in different glacial settings in the Weddell...

The role of large-scale drivers in the Amundsen Sea Low variability and associated changes in water isotopes from the Roosevelt Island ice core, Antarctica
Here we examine the water stable-isotope data from the Roosevelt Island Climate Evolution (RICE) ice core. Roosevelt Island is an independent ice...

Impacts of the long-term atmospheric trend on the seasonality of Antarctic sea ice
The sea ice cover has experienced substantial changes in Antarctica in the past decades, yet its responses to the long-term trend of the local...

Retrieval of Antarctic sea ice freeboard and thickness from HY-2B satellite altimeter data
Antarctic sea ice is an important part of the Earth’s atmospheric system, and satellite remote sensing is an important technology for observing...

Contraction and warming of Antarctic Bottom Water in the Amundsen Sea
Antarctic Bottom Water (AABW) plays an important role in the meridional overturning circulation and contributes significantly to global heat...

Retrieval of snow depth on Antarctic sea ice from the FY-3D MWRI data
The snow depth on sea ice is an extremely critical part of the cryosphere. Monitoring and understanding changes of snow depth on Antarctic sea ice is...

Southern Ocean sea ice concentration budgets of five ocean-sea ice reanalyses
In this study, sea ice concentration (SIC) budgets were calculated for five ocean-sea ice reanalyses (CFSR, C-GLORSv7, GLORYS12v1, NEMO-EnKF and...

Interannual variability of air temperature inversions in ice-free area of northern James Ross Island, Antarctica
Air temperature inversions are common features in Antarctica, especially in the interior where they are observed nearly year-round. Large temporal...
