Airborne environmental DNA (airborne eDNA) analysis leverages the globally ubiquitous medium of air to deliver broad species distribution data and support ecosystem monitoring across diverse environments. As this emerging technology matures…
Like many polar animals, emperor penguin populations are challenging to monitor because of the species' life history and remoteness. Consequently, it has been difficult to establish its global status, a subject important to resolve as polar environments change.
Antarctic ice core records offer a key resource for understanding late Holocene climate … in the high latitude Southern Hemisphere, and potentially beyond.
Our aim was to estimate the population of emperor penguins (Aptenodytes fosteri) using a single synoptic survey. We examined the whole continental coastline of Antarctica using a combination of medium resolution and Very High Resolution (VHR)…
Sea ice plays an important role in ocean–atmosphere heat exchange, global albedo and the marine ecosystem. Knowledge of variation in sea-ice extent is essential in order to understand past climates, and to model possible future climate scenarios.
The Agreement on the Conservation of Albatrosses and Petrels (ACAP) is a newly-constituted international treaty that as yet may be little … known to marine ornithologists around the world. We outline the rationale for the existence of the Agreement, the history of its development…
ABSTRACT. The Committee for Environmental Protection (CEP) was established under the Protocol on … Environmental Protection to the Antarctic Treaty to advise the Antarctic Treaty Consultative Meeting (ATCM) on … matters relating to protection of the Antarctic environment.
Conventionally the source of sea salt in the Antarctica was considered to be the ocean … surface. In simple terms, sea salt is ejected into the atmosphere as sea spray droplets, mixed … in the atmosphere, and transported to Antarctica via storm activity. Recently, however…
This paper provides the first evidence to relate Leopard Seal numbers with sea-ice … concentrations in a region of the Eastern Antarctic pack ice and to propose a biological … mechanism (krill availability) to link the two. Leopard seals have been periodic, and sometimes numerous…
