Abstract. Landfast sea ice (fast ice) is an important component of the Antarctic nearshore marine environment, where it strongly modulates ice sheet-ocean-atmosphere interactions and biological and biogeochemical processes, forms a key habitat, and affects logistical operations. Given the wide-ranging importance of Antarctic fast ice and its sensitivity to climate change, improved knowledge of its distribution (and change and variability therein) is a high priority. Antarctic fast-ice mapping to date has been limited to regional studies and a time series covering East Antarctica from 2000 to 2008. Here, we present the first continuous, high spatiotemporal resolution (1 km, 15 day) time series of circum-Antarctic fast ice extent; this covers the period March 2000 to March 2018, with future updates planned. This dataset was derived by compositing cloud-free satellite visible-thermal infrared imagery using an existing methodology, modified to enhance automation and reduce subjectivity in defining the fast ice edge. This ground-breaking new dataset (Fraser et al., 2020) has wide applicability, and is available at The new algorithm presented here will enable continuous large-scale fast ice mapping and monitoring into the future.

Short summary
Landfast ice, or fast ice, is a form of sea ice which is mechanically fastened to stationary parts of the coast. Long-term and accurate knowledge of its extent around Antarctica is critical for understanding a number of important Antarctic coastal processes, yet no accurate, large-scale, long-term dataset of of its extent has been available. We address this data gap with this new dataset compiled from satellite imagery, containing high-resolution maps of Antarctic fast ice from 2000 to 2018.
