The Arctic Ocean is a rapidly changing environment, and a key observational system for monitoring climate change. The Arctic is going under a rapid transition from thicker, multi-year ice, to thinner first-year ice, that may have many potential consequences. As first year Arctic sea ice begins to retreat in the spring and early summer, melting snow and ice form ponds on the surface- “melt ponds”. These melt ponds increase light transmission to the water column, resulting in warming and increased primary production under the ice. Recent advances in high resolution satellite imagery now allow us to monitor the development and propagation of melt ponds from space. 14 Worldview images (privately owned) of first year ice in the Chukchi Sea with sub-meter scale spatial resolution were recorded from June and July 2018 and classified into 4 distinct classes- Un-ponded Ice, Dark Melt Pond, Light Melt Pond, and Open Water.
