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 ...

Remote Sensing in Ecology and Conservation, EarlyView.Autonomous fixed‐wing drones operating beyond visual line of sight of the pilot were used to conduct the first aerial, multi‐species baseline reference survey at the sub‐Antarctic island of South Georgia. Long‐term population monitoring in this remote, challenging environment has historically proved difficult, with terrestrial monitoring generally ...

Remote Sensing in Ecology and Conservation, EarlyView.Adélie penguins gather in colonies as standing or prone adults, individual chicks, and chick crèches. From drone images, we distinguish adults and chicks by their plumage, identify adult postures by body shape, and estimate the size of chick groups from the area they occupy. We map these groups and measure how closely penguins live together.

Gravity analyses for the crustal structure and subglacial geology of West Antarctica, particularly beneath Thwaites Glacier [PDF]
, 2008 textThe West Antarctic Ice Sheet (WAIS) is mostly grounded in broad, deep basins (down to 2.5 km below sea level) that are stretched between five crustal blocks. The geometry of the bedrock, being mostly below sea level, induces a fundamental instability

Геологія і корисні копалини Світового океану, 2019 It is shown that the continent of Antarctica, where the South Geographical Pole of the Earth is located, is the geodynamic center of formation of the primary crust of the planet. It is in the southern region of the planet, in accordance with the rules of

Unraveling the impact of dog‐friendly spaces on urban–wildland pumas and other wildlife
Wildlife Biology, EarlyView.As the most widespread large carnivore on the planet, domestic dogs Canis lupus familiaris can pose a major threat to wildlife, even within protected areas (PAs). Growing human presence in PAs, coupled with increasing pet dog ownership underscores the urgency to understand the influence of dogs on wildlife activity and health.

Critical constraints to ecological buffering in a rapidly changing Arctic: A long‐term seabird study
Journal of Animal Ecology, EarlyView.Drawing on two decades of research in East Greenland, this study shows that little auks, key seabird indicators of Arctic ecosystem health, can adapt to rapid environmental change through behavioural flexibility. However, increasing storms and mercury pollution are pushing resilience to its limits, providing an early warning of broader Arctic ...

Archiving the History of Environmentalism: Insights from Academia and Practice
History, EarlyView.Abstract This Forum considers the current state of archiving for the environmental movement at local, national and international levels. It responds to a gap that researchers of environmentalism have long been aware of, but one that is poorly understood from the perspective of records management and collections development practice.
