Abstract |
Abstract. Current Volcanic Reconstructions Based On Ice Core Analysis Have Significantly Improved Over The Past Few Decades By Incorporating Multiple-core Analyses With A High Temporal Resolution From Different Parts Of The Polar Regions Into A Composite Common Volcanic Eruption Record. Regional Patterns Of Volcanic Deposition Are Based On Composite Records, Built From Cores Taken At Both Poles. However, In Many Cases Only A Single Record At A Given Site Is Used For These Reconstructions. This Assumes That Transport And Regional Meteorological Patterns Are The Only Source Of The Dispersion Of The Volcanic Products. Here We Evaluate The Local-scale Variability Of A Sulfate Profile In A Low-accumulation Site (Dome C, Antarctica), In Order To Assess The Representativeness Of One Core For Such A Reconstruction. We Evaluate The Variability With Depth, Statistical Occurrence, And Sulfate Flux Deposition Variability Of Volcanic Eruptions Detected In Five Ice Cores, Drilled 1 M Apart From Each Other. Local-scale Variability, Essentially Attributed To Snow Drift And Surface Roughness At Dome C, Can Lead To A Non-exhaustive Record Of Volcanic Events When A Single Core Is Used As The Site Reference, With A Bulk Probability Of 30 % Of Missing Volcanic Events And Close To 65 % Uncertainty On One Volcanic Flux Measurement (Based On The Standard Deviation Obtained From A Five-core Comparison). Averaging N Records Reduces The Uncertainty Of The Deposited Flux Mean Significantly (By A Factor 1∕ √ N); In The Case Of Five Cores, The Uncertainty Of The Mean Flux Can Therefore Be Reduced To 29 %. |

Abstract |
Contrasting regional changes in Southern Ocean sea ice have occurred over the last 30 years with distinct regional effects on ecosystem structure and function. Quantifying how Antarctic predators respond to such changes provides the context for predicting how climate variability/change will affect these assemblages into the future. Over an 11-year time-series, we examine how inter-annual variability in sea ice concentration and advance affect the foraging behaviour of a top Antarctic predator, the southern elephant seal. Females foraged longer in pack ice in years with greatest sea ice concentration and earliest sea ice advance, while males foraged longer in polynyas in years of lowest sea ice concentration. There was a positive relationship between near-surface meridional wind anomalies and female foraging effort, but not for males. This study reveals the complexities of foraging responses to climate forcing by a poleward migratory predator through varying sea ice property and dynamic anomalies. |
