Antarctic total ozone longitude–latitude dependence on sudden stratospheric warmings EGU General Assembly 2024, Vienna, Austria, 14–19 Apr 2024, 2024 (Ref: 17160)
Category 3: Abstract

We use Multi-Sensor Reanalysis and ground-based total ozone content (TOC) data to study total ozone variations in Antarctica near the dates of sudden stratospheric warmings (SSW). Three events were analyzed, including the warmings in 1988, 2002 (major warming), and 2019.

Using telemetry data and the sea ice satellite record to identify vulnerabilities in critical moult habitat for emperor penguins in West Antarctica. Polar Biology, 2024 (Ref: 17087)
Category 1: Peer-reviewed literature

We tracked adult emperor penguins from Rothschild Island, west Antarctic Peninsula in 2015/2016 during a summer with extensive sea ice of long duration, contrasting with past years of reduced sea ice extent associated with the recent, rapid, warming trend across the region.
