Distribution and Abundance of Breeding Birds at Deception Island, South Shetland Islands, Antarctica, February to April 2000

Distribution and abundance of breeding birds at Deception Island, South Shetland Islands, Antarctica, February to April 2000. Marine Ornithology 29: 39–42. A survey of breeding birds during the brooding stage was carried out from February to April 2000 in the southern portion of Deception Island, South Shetland Islands, Antarctica. This island supports two Sites of Special Scien- tific Interest (SSSI Nos. 21 and 27). Nine species were found breeding in the study area: Chinstrap Penguin Pygoscelis antarctica (an estimated 6820 breeding pairs at two colonies surveyed), Pintado or Cape Petrel Daption capense (36), Wilson’s Storm Petrel Oceanites oceanicus (3), Antarctic Cormorant Phalacrocorax atriceps bransfieldensis (9), Greater Sheathbill Chionis alba (2), Subantarctic Skua Catharacta antarctica (4), South Polar Skua C. maccormicki (11), Kelp Gull Larus dominicanus (49) and Antarctic Tern Sterna vittata (5). Due to the increasing tourist activity at Deception Island, better information on the location and size of breeding populations is a particular requirement if effective precautionary conservation actions are to be taken.

Bransfield Basin Fine-Grained Sediments: Late-Holocene
The Holocene 10,6 (2000) pp. 703–718 Bransfield Basin fine-grained sediments: late-Holocene sedimentary processes and Antarctic oceanographic conditions J. Fabre´s,1 A. Calafat,1* M. Canals,1 M.A. Ba´rcena2 and J.A. Flores2 (1G.R.C. Geocie`ncies Marines, Departament d’Estratigrafia i Paleontologia, Universitat de Barcelona, Campus Universitari de Pebralbes, E-08028 Barcelona, Spain; 2Departamento de Geologı´a, Facultad de Ciencias, Universidad de Salamanca, E-37008 Salamanca, Spain) Received 28 July 1999; revised manuscript accepted 24 February 2000 Abstract: The Antarctic Peninsula is sensitive to climatic change due to its northerly position and to the relatively reduced volume and character of its ice cover. High-resolution palaeoclimatic records from the Ant- arctic Peninsula ice cores extend back only 500 years. A climatic record of 2850 years in the Bransfield Basin is investigated through the analysis of sediment gravity cores from the floor of the central subbasin (core GEBRA-1) and the slope of the eastern subbasin (core GEBRA-2). Sedimentological, mineralogical and geo- chemical properties have been systematically measured, together with Accelerator Mass Spectrometry (AMS) radiocarbon dating. The fine-grained sediments result from two main processes: hemipelagic settling from resuspensions and primary productivity, and turbidity currents. Hemipelagic sediments were selected to investi- gate the oceanographic and climatic conditions of the northern Antarctic Peninsula region during the last three millennia. Cold climatic periods are characterized by millimetric laminations and/or black layers with higher organic carbon, nitrogen and opal contents. Warm periods are recorded as massive to diffuse laminated facies with lower biogenic contents. -
Antarctica 14Th February – 3Rd March 2019
An Ultimate Invitation: Antarctica 14th February – 3rd March 2019 Hosted by Nick and Iris Van Gruisen With Guest Lecturers Dr Huw Lewis Jones, Kari Herbert and Nigel and Shane Winser. The Ultimate Travel Company Escorted Tours Map count Introduction There is nothing on this earth that can quite compare with the awesome beauty of Antarctica, and few of us have not dreamed of following Scott, Shackleton and Amundsen to these frozen wastelands at the bottom of the world. So why not turn those dreams into reality and join us on a very special journey to the Great White Continent? Here, in this world of perpetual snow and ice below the 60th parallel, some of the world’s most enchanting creatures survive to bring colour and sound to an otherwise harsh and silent environment. Beaches resound to the raucous bellows of elephant, fur and leopard seals, Humpback and Minke whales glide effortlessly through the still, near-frozen waters, and colonies of Adelie, Chinstrap, Gentoo and King Penguin congregate in huge numbers on the vast snow plains. The RCGS Resolute is the ideal vessel for such an expedition with her unsurpassed ice classification, her excellent manoeuvrability and large indoor and outdoor viewing platforms. She is also extremely comfortable with all cabins with en suite facilities and excellent public areas. She has 146 berths, but we will be limiting numbers to around 90 to ensure even more personal service and space. Lastly, we have been fortunate enough to negotiate an excellent rate so the expedition offers excellent value, especially the Single Supplement. Zodiacs are used for the daily on-shore excursions and for the more adventurous the Kayak is also available (limited numbers) and maybe even a chance to spend a night on the ice-shelf. -
