Title: Observational Approaches for Seasonal Sea Ice Environments

Abstract: Melting summer Arctic sea ice is one of the most visible indicators of climate change. Ice that grows out of open water, increasingly common in the modern Arctic, presents particular challenges for observation. This presentation covers two remote sensing methods developed to study first-year ice environments. The first uses an ice-tracking algorithm to trace ice floes backwards through the winter from an end-of-season ice thickness measurement to the time and location of freeze-up. The second method addresses a remote sensing gap: persistent monitoring of ice conditions on coastlines. Initial validation against Alaska Native community records show that this approach can detect freeze-up events and seasonal breakup. This data product will provide a more complete estimate of sea ice extent in the Arctic and will be a tool for operational ice centers that require sea ice information near shorelines.

Bio: Alice Bradley is a postdoctoral researcher at Dartmouth College. She develops methods for observing coastal sea ice, including instrumented buoys and remote sensing techniques. She completed her PhD at the University of Colorado Boulder in 2016 with a dissertation on observed over-winter feedback processes in the Arctic seasonal ice zones. Alice was President APECS in 2016-7 and is now an IASC Fellow for the Cryosphere Working Group.
