Historical remote sensing highlights long‐term persistence of Emperor Penguin (Aptenodytes forsteri) colonies

Remote Sensing in Ecology and Conservation, EarlyView.
Remote sensing can reveal population dynamics of Antarctic penguin colonies. In this study, we analyze emperor penguin (Aptenodytes forsteri) guano stains in remote sensing imagery and discover colony presence predating known records for 18 colonies across Antarctica.

ICE-SHELF RESPONSE TO ICE-STREAM DISCHARGE FLUCTUATIONS: 11. IDEAL RECTANGULAR ICE SHELF

, 2014
. Ice-shelf thickness and velocity anomalies resulting from ice-stream discharge fluctuations are calculated for an ideal ice shelf fed by a single ice stream and confined within a rectangular coastal geometry.

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Tracking Wintertime Behaviour of Emperor Penguins Using High‐Resolution Synthetic Aperture Radar Imagery

Remote Sensing in Ecology and Conservation, EarlyView.
Using 25–30 cm Umbra synthetic aperture radar (SAR) imagery combined with ground validation of our observations, we introduce a method to track the phenology of emperor penguins during the Antarctic winter. We successfully identified events in the breeding cycle, which were previously impossible to observe during the complete darkness of Antarctic ...
