9 New MEaSURES Copernicus-1 ice sheet mosaic dataset These mosaics were generated through a grant from the NASA MEaSUREs program. Contains modified Copernicus Sentinel data ( ), acquired by the European Space Agency, distributed through the Alaska Satellite Facility, and processed by Joughin, I. Courtesy I. Joughin / NASA, MEaSURES The WMO Polar Space Task Group is acknowledged for its role in coordinating the routine Copernicus Sentinel-1 Greenland acquisition plans.

10 Ice Shelf calving and fracturing events (1 of 2) Larsen-C and Pine Island Glacier calving events, and Brunt Ice Shelf fracture propagation monitored by ESA-developed EU Copernicus Sentinel missions: Copernicus Sentinel-3 gives large view of the Antarctic Peninsula and Larsen-C A68 iceberg Copernicus Sentinel-1 indicating Halloween crack extension in Brunt Ice Shelf; darker area in Weddell Sea shows a polynya. BAS decision taken not to overwinter in 2018 based on latest November 2017 situation observed here 19 October, 2017 Copernicus Sentinel-2 image of Pine Island Glacier B-44 iceberg break-up, after calving ESA UNCLASSIFIED - For Official Use Mark Drinkwater 03/09/2017 Slide 10

11 Brunt ice shelf fracture propagation 10 Nov., 2017 Copernicus Sentinel-2 images of Brunt Ice shelf showing chasms threatening Halley VI research base. In right panel (stretched image brightness scale) one can identify the old and new Halley VI location, and the tractor tracks along which the buildings were moved during the austral summer 2016/17 (prior to summer closure). The Halloween Crack discovered on 31 October, 2016 (visible at upper left), has extended up-glacier during 2017 threatening the long-term stability of the ice shelf.

New Polar Dataset: Proba-V Antarctic acquisitions By request from the user community, Proba-V satellite to acquire images over Antarctica from November 2017 to February km, 300 m and 100 m products will be processed up to L2A and provided in a polar stereographic projection. Products will be made available online through the regular product distribution portal and the Proba-V Mission Exploitation Platform (MEP). An announcement will be made when these products are available to download. In the figure below, the small image on the left shows the planned orbit acquisitions to capture the total land mass of Antarctica in 1 km or 300 m resolution. The image on the right shows the result of a seamless mosaic of these orbits, projected and cropped to the land borders.
