An emerging technique: multi-ice-core multi-parameter correlations with Antarctic sea-ice extent
Using results stemming from the International Trans-Antarctic Scientific Expedition (ITASE) ice-core array plus data from ice cores from the South Pole and Siple Dome we investigate the use of sodium (Na), non-sea-salt sulfate (nssSO4 ) and methylsulfonate (MS) as proxies for Antarctic sea-ice extent (SIE). Maximum and mean annual chemistry concentrations for these three species correlate signi...

متن کاملSources of multi-decadal variability in Arctic sea ice extent
The observed dramatic decrease in September sea ice extent (SIE) has been widely discussed in the scientific literature. Though there is qualitative agreement between observations and ensemble members of the Third Coupled Model Intercomparison Project (CMIP3), it is concerning that the observed trend (1979–2010) is not captured by any ensemble member. The potential sources of this discrepancy i...
متن کاملIterative Estimation of Antarctic Sea Ice Extent Using SeaWinds Data
Polar sea ice extent is an important input to global climate models and is considered to be a sensitive indicator of climate change. An algorithm has previously been developed for sea ice extent detection using data from the NASA scatterometer (NSCAT). This paper discusses the extension of that algorithm to data from SeaWinds on QuikSCAT. Due to differences in the two instruments, several modif...
