The earlier era moved ice between regions; since 2015 every sector has lost ice-covered months. https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/39065877-21d8-48a3-9aff-c0efaa995966/03_antarctic_peninsula_preview.jpg Cartographic and Science Visualization Products Antarctic Peninsula: a reference map of the Peninsula, extended south to the head of the Weddell Sea.

This figure from a 2026 proposal to NASA explores whether satellite images could help researchers find seals across a wider area and tell species apart. (a–b) Gold marks existing WorldView-3 imagery in Alaska’s Kotzebue Sound and Beaufort Sea. Blue shows where spring ice stays attached to shore longest in Kotzebue Sound. (c–e, i) Two satellite images show the same patch of Beaufort Sea ice. Individual floes come into focus in the finer Landsat image, where 185 floes range from about 200 meters to several kilometers across. (f–h) A NOAA aircraft photo shows a bearded seal (red box) beside a smaller ringed seal (blue box). Both remain visible when the photo is reduced to WorldView-3’s 31-centimeter pixels, though a real satellite image would look softer. (j) In the aircraft survey, bearded seals measured about 2.2 meters long and ringed seals about 1.3 meters. At satellite resolution, that’s roughly seven pixels versus four, a potential clue to species identity. https://www.michaeljwethington.com/software daily 0.75 2026-11-06 https://www.michaeljwethington.com/work-1 daily 1.0 2026-11-06 https://www.michaeljwethington.com/work-1/project-four-ejbcj monthly 0.5 2024-06-01 https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/dcd341db-8a85-4be7-bdec-8b9f6fc5fdfb/Wethington+et+al.+-+2024+-+Seal+Occupancy+Patterns_Figure01.jpg https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/c3f2cd43-e068-4604-8cae-cfd66c20ad86/Wethington+et+al.+-+2024+-+Seal+Occupancy+Patterns_Figure02.jpg https://www.michaeljwethington.com/work-1/project-one-hw2h8 monthly 0.5 2024-06-01 https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/ab222604-9167-41ca-978b-f634bb63918a/Wethington+et+al.+-+2023+-+Ad%C3%A9lie+penguins+north+and+east+of+the+%E2%80%98Ad%C3%A9lie+gap%E2%80%99_Page_01.png https://www.michaeljwethington.com/work-1/project-three-fgghs monthly 0.5 2024-06-08 https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/e05c9c2a-6995-45a0-a364-b285cd09f1a3/Wethington+et+al.+-+2024+-+Species+classification+of+Antarctic+pack%E2%80%90ice+seals_Page_01.png https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/337f4bfb-08cb-4f5f-85ce-d889b0a8965d/Wethington+et+al.+-+2024+-+Species+classification+of+Antarctic+pack%E2%80%90ice+seals_Figure.png https://www.michaeljwethington.com/work-1/project-two-lsjrl monthly 0.5 2026-11-06 https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/6d4c01ed-9451-4139-a8cb-e118d2341113/IMG_8775.JPEG https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/926793b1-2790-4ed9-aa5b-6b0539c91ec5/01_elephant_island_colonies.jpg https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/74e0ea3b-4727-4d08-beed-f53dcb9c5c8f/IMG_8687.JPEG https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/e63dbf7c-2187-4943-97ee-2541acff21db/F8QVSVbaYAAC4PD.jpg https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/e15a7e4d-2903-4ca1-ae2f-ef9bbaa01344/IMG_2299.JPEG
