Ice sheet record of recent sea-ice behavior and polynya variability in the Amundsen Sea, West Antarctica
[1] Our understanding of past sea-ice variability is limited by the short length of satellite and instrumental records. Proxy records can extend these observations but require further development and validation. We compare methanesulfonic acid (MSA) and chloride (Cl) concentrations from a new firn core from coastal West Antarctica with satellite-derived observations of regional sea-ice concentr...
متن کاملLead Sources to the Amundsen Sea, West Antarctica.
The global prevalence of industrial lead (Pb) contamination was exemplified decades ago by the predominance of anthropogenic Pb in samples of Antarctic surface ice and in Southern Ocean surface waters. Decreases in environmental Pb contamination corresponding with the near-global phase-out of leaded automobile gasoline beginning in the 1970s have since been observed. Measurements of Pb concentr...
متن کاملTropical forcing of Circumpolar Deep Water Inflow and outlet glacier thinning in the Amundsen Sea Embayment, West Antarctica
Outlet glaciers draining the Antarctic Ice Sheet into the Amundsen Sea 1 Embayment (ASE) have accelerated in recent decades, most likely as a result of increased 2 melting of their ice shelf termini by warm Circumpolar Deep Water (CDW). An ocean 3 model forced with climate reanalysis data shows that, beginning in the early 1990s, an 4 increase in westerly wind stress over the continental shelf ...
متن کاملLate Quaternary ice sheet dynamics and deglaciation history of the West Antarctic Ice Sheet in the Amundsen Sea Embayment: Preliminary results from recent research cruises
Late Quaternary ice sheet dynamics and deglaciation history of the West Antarctic Ice Sheet in the Amundsen Sea Embayment: Preliminary results from recent research cruises" (2007). Related Publications from ANDRILL Affiliates. Paper 8. Summary The threat, in terms of sea level rise, posed by the potential rapid deglaciation of West Antarctica means there is an urgent need to know more about the...
متن کاملSpatial Patterns in Mass Balance of the Siple Coast and Amundsen Sea Sectors, West Antarctica
Local rates of change in ice-sheet thickness were calculated at 15 sites in West Antarctica using the submergence velocity technique. This method entails a comparison of the vertical velocity of the ice sheet, measured using repeat global positioning system surveys of markers, and local long-term rates of snow accumulation obtained using firn-core stratigraphy. Any significant difference betwee...
