Each circle is scaled to the most recent survey estimate at that site and colored by the species holding the most nests there. https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/8a2f9e2a-5906-46b7-aca4-1bd09f34c0ab/02_elephant_island_place_names.jpg Maps Elephant Island place names: the same terrain with the colony layer removed, naming 48 capes, points, beaches, bays, glaciers, ridges and offshore islands from the Composite Gazetteer of Antarctica. https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/ed6ed4c0-9b9f-44ec-a510-11d3469d53ee/03_antarctic_peninsula_reference.jpg Maps Antarctic Peninsula reference map: a locator sheet that follows the frame of the British Antarctic Survey’s Peninsula overview and extends it south to the head of the Weddell embayment. https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/703a4ca1-4b42-47bb-af27-6e149866c0b2/04_antarctic_sea_ice_record.jpg Maps The Antarctic sea ice record, 1979 to 2026, from the NOAA and NSIDC Sea Ice Index. Antarctic sea ice rose slowly until about 2014 and has fallen since. https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/c8e9f594-36ae-46f8-a10f-9eb52121564c/05_antarctic_sea_ice_extent_2016_2025.jpg Maps Antarctic sea ice extent: median September and February extent in 2016 to 2025 compared with the 1981 to 2010 reference period, with the continent drawn in relief from the Reference Elevation Model of Antarctica. https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/287a1bb4-faa8-4bf4-840b-4d09537a5a8e/06_antarctic_sea_ice_change.jpg Maps Antarctic sea ice change: the same comparison drawn as change, red where the earlier period had ice and the recent one does not, blue where the reverse holds. https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/69e62344-61a0-4ab0-8de9-b83d1851e7fe/07_antarctic_sea_ice_two_eras.jpg Maps Change in Antarctic sea ice season length across the growth era (1979 to 2014) and the loss era (2015 to 2025). The earlier era moved ice between regions; since 2015 every sector has lost ice-covered months. https://www.michaeljwethington.com/work-1 daily 1.0 2026-10-16 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 2024-06-08 https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/6d4c01ed-9451-4139-a8cb-e118d2341113/IMG_8775.JPEG https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/e92f8788-6a02-4dec-986f-8b12ea70e74c/ElephantIsland_Figure2_SidebySide_2020Oct28.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/v1/6659dbf075f73d3b9f96ec62/047281ca-8b7b-4b81-804e-d467bfae0d8a/1-s2.0-S0278434321002284-gr6.jpg https://images.squarespace-cdn.com/content/v1/6659dbf075f73d3b9f96ec62/e15a7e4d-2903-4ca1-ae2f-ef9bbaa01344/IMG_2299.JPEG
