Antarctic datasets

The following is a list of publically available Antarctic datasets. These datasets are often freely accessible, usually providing that you cite the source and often a relevant paper. Do not use data without correct attribution. Many of these datasets have been used in the creation of figures on this website, and I thank all the …

Sea level rise over the next 2000 years

A new paper by Levermann et al. in PNAS uses the record of past rates of sea level rise from palaeo archives and numerical computer models to understand how much sea level rise we can expect per degree of warming in the future. These data suggest that we can expect a global sea level rise …

West Antarctic Ice Sheet

Introduction | Topography | Oceanography | Ice streams and ice shelves | References | Comments | Introduction The West Antarctic Ice Sheet (the WAIS) is capable of rapid change as it is a marine ice sheet and therefore could be unstable. It has the potential to raise global sea level by 3.3 m[1] over a …

Marine ice sheet instability

Introduction | Past evidence of ice sheet collapse | Hypothesis of marine ice sheet instability | References | Comments | Introduction In 1978, Mercer was one of the first to identify that rising temperatures could have catastrophic consequences in West Antarctica, triggering a collapse of the West Antarctic Ice Sheet[1]. This is because much of …

Ice shelf collapse

What is an ice shelf? | Ice shelf collapse | Mechanisms of ice shelf collapse | Ice shelf buttressing | References | Comments What is an ice shelf? Ice shelves are floating tongues of ice that extend from grounded glaciers on land. Snow falls on glaciers, which flow downstream under gravity. Ice shelves are common …
