Résumé:
Dynamic climate changes have become noticeable in recent decades, especially in the vulnerable region of Western Antarctic. It is widely assumed that Antarctic biota are sensitive to environmental changes. Admiralty Bay (King George Island, South Shetland Islands, Antarctic Peninsula) has been the site of comprehensive environmental studies over the last 30 years and existing data sets provide Read More

UAV for monitoring environmental changes on King George Island (South Shetland Islands) Antarctica: preliminary study on wildlife disturbance A. Kidawa, M. Korczak-Abshire, A. Zmarz, R. Storvold, M. Rodzewicz, K. Chwedorzewska, S-R. Karlsen and A. Znój (Poland)
Résumé:
The importance of Unmanned Aerial Vehicles (UAVs) in remote sensing is rapidly growing. However, knowledge about their potential impact on wildlife is scant, especially in the Antarctic, where they are a new tool used in ecological research and monitoring.
In this preliminary study we investigate potential effects of wildlife disturbance by UAVs. In austral summer 2014-2015 UAV Read More

Résumé:
An integrated assessment model for Antarctic krill in FAO Subarea 48.1 that incorporates catch and length-composition data from the krill fishery with biomass indices and length-compositions from research surveys has been developed. The model uses statistical fits to these data to estimate the effects of the fishery on the krill population. The model estimates parameters representing krill Read More

Résumé:
We present definitive evidence, derived from two independent methods (satellite tagging and photo-identification), that TCKW undergo long-distance travel from the southern Ross Sea to New Zealand waters and into subtropical regions (31°-35°S). This not only establishes ecosystem connectivity between the Ross Sea and New Zealand, but also emphasises the urgent need to re-evaluate the profile of Read More

Résumé:
Annual acoustic trawl surveys for krill monitoring have been carried out by the Institute of Marine research, Norway near the South Orkney Islands since 2011. The survey has been conducted early in the fishing season (January/February), using two different krill fishing vessels as platforms.

Résumé:
In this paper, we develop a candidate management system for the krill fishery suitable for achieving objectives for krill and its predators in local areas. We also indicate how this management system can be made operational in the early phases of a fishery in a local area, which can then be enhanced as the fishery develops, including testing future management procedures and in adapting them to Read More

Résumé:
Antarctic ecosystems are dynamic and characterized by physically forced variability caused e.g. by fronts, eddies and ice. This creates a challenging dynamics for scientific sampling and monitoring. Realistic understanding of what can and cannot be achieved with the available sampling techniques and strategies is essential.

Résumé:
VHF radiotelemetry data has been used for over thirty years to monitor the behavior patterns of otariid seals. These data have been used in a wide variety of ways, from characterizing the reproductive and foraging ecology of these species to inferring ecosystem changes based on variation in attendance patterns. Yet the accuracy of VHF data has never been appropriately evaluated. Our study Read More

Résumé:
Quantifying the distribution and abundance of predators is integral to many ecological studies, but can be difficult in remote settings such as Antarctica. Recent advances in the development of unmanned aerial systems (UAS), particularly vertical takeoff and landing (VTOL) aircraft, have provided a new tool for studying the distribution and abundance of predator populations.
