Today, the krill fishery operates mostly in the waters around the Antarctic Peninsula. CCAMLR manages the fishery by imposing catch limits that are allocated across designated subareas of the Southern Ocean. Antarctic krill is the base of the food web in the region and provides protein for many key predators, including penguins. Although fishery management measures have been effective in regulating krill catches, they have not adequately accounted for the foraging needs of penguins and other predators that depend on krill for food. In addition to the impact of concentrated fishing, climate change is reducing the availability of krill in the foraging areas of species such as chinstrap and Adélie penguins, especially near the coast of the Antarctic Peninsula. Declines of this integral forage species could create a ripple effect throughout the Antarctic food web and cause imbalances in key predator-prey relationships. CCAMLR has a mandate to protect all biodiversity within Antarctic waters. It must protect the Southern Ocean by protecting the base of the food web—krill.

Joint Conference of the History EG and Humanities and Social Sciences
Joint conference of the History EG and Humanities and Social Sciences EG "Antarctic Wilderness: Perspectives from History, the Humanities and the Social Sciences" Colorado State University, Fort Collins (USA), 20 - 23 May 2015 A joint conference of the History Expert Group and the Humanities and Social Sciences Expert Group on "Antarctic Wilderness: Perspectives from History, the Humanities and the Social Sciences" was held at Colorado State University in Fort Collins (USA) on 20-23 May 2015. On Wednesday (20 May) we started with an excursion to the Rocky Mountain National Park close to Estes. A hike of two hours took us along a former golf course that had been remodelled as a natural plain, and served as a fitting site for a discussion with park staff on “comparative wilderness” given the different connotations of that term in isolated Antarctica and comparatively accessible Colorado. After our return to Fort Collins we met a group of members of APECS (Association of Polar Early Career Scientists), with whom we had a tour through the New Belgium Brewery. The evening concluded with a screening of the film “Nightfall on Gaia” by the anthropologist Juan Francisco Salazar (Australia), which provides an insight into current social interactions on King George Island and connections to the natural and political complexities of the sixth continent. The conference itself was opened by on Thursday (21 May) by Diana Wall, head of the School of Global Environmental Sustainability at the Colorado State University (CSU). Andres Zarankin (Brazil) opened the first session on narratives and counter narratives from Antarctica with his talk on sealers, marginality, and official narratives in Antarctic history.

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.

Bridging the Krill Divide: Understanding Cross-Sector Objectives for Krill Fishing and Conservation
Bridging the Krill Divide: Understanding Cross-Sector Objectives for Krill Fishing and Conservation Report of an ICED-BAS-WWF workshop on UNDERSTANDING THE OBJECTIVES FOR KRILL FISHING AND CONSERVATION IN THE SCOTIA SEA AND ANTARCTIC PENINSULA REGION held at WWF’s Living Planet Centre, Woking, UK on 9th & 10th June 2014 Report compiled and edited by: Simeon Hill, Rachel Cavanagh, Cheryl Knowland, Susie Grant and Rod Downie Integrating Climate and Ecosystem Dynamics in the Southern Ocean Bridging the Krill Divide: Understanding Cross-Sector Objectives for Krill Fishing and Conservation SUMMARY In June 2014, the ICED programme, the British need to increase catch limits. Participants also agreed Antarctic Survey and WWF co-hosted a two day that the objectives of management must include a workshop entitled “Understanding the objectives for healthy krill stock and a healthy ecosystem. However, krill fishing and conservation in the Scotia Sea and they were not able to define ecosystem states that Antarctic Peninsula region” which involved participants are desirable or healthy. This reflects the gaps in the from the science, conservation, and fishing industry currently available information and the indirect nature sectors. The workshop used structured dialogue, led of the links between the krill-based ecosystem and by an independent facilitator, to explore each sector’s human well being. The workshop produced a range of objectives and information requirements for the krill- recommendations including the need to articulate a based ecosystem and to identify constructive ways for clear research and development strategy to support the three sectors to work together. The issue of krill progress in the management of the krill fishery, and fishing has previously provoked passionate debate but to improve communication between the Commission participants in this workshop showed broad cross- for the Conservation of Antarctic Marine Living sector accord.

The glaciers on the Antarctic Peninsula (AP) potentially make a large contribution to sea level rise. However, this contribution has been difficult to estimate since no complete glacier inventory (outlines, attributes, separation from the ice sheet) is available. This work fills the gap and presents a new glacier inventory of the AP north of 70◦ S, based on digitally combining preexisting data sets with geographic information system (GIS) techniques. Rock outcrops have been removed from the glacier basin outlines of Cook et al. (2014) by inter- section with the latest layer of the Antarctic Digital Database (Burton-Johnson et al., 2016). Glacier-specific topographic parameters (e.g., mean elevation, slope and aspect) as well as hypsometry have been calculated from the DEM of Cook et al. (2012). We also assigned connectivity levels to all glaciers following the concept by Rastner et al.

Living and Working at USAP Facilities
Chapter 6: Living and Working at USAP Facilities CHAPTER 6: Living and Working at USAP Facilities McMurdo Station is the largest station in Antarctica and the southermost point to which a ship can sail. This photo faces south, with sea ice in front of the station, Observation Hill to the left (with White Island behind it), Minna Bluff and Black Island in the distance to the right, and the McMurdo Ice Shelf in between. Photo by Elaine Hood. USAP participants are required to put safety and environmental protection first while living and working in Antarctica. Extra individual responsibility for personal behavior is also expected. This chapter contains general information that applies to all Antarctic locations, as well as information specific to each station and research vessel. WORK REQUIREMENT At Antarctic stations and field camps, the work week is 54 hours (nine hours per day, Monday through Saturday). Aboard the research vessels, the work week is 84 hours (12 hours per day, Monday through Sunday). At times, everyone may be expected to work more hours, assist others in the performance of their duties, and/or assume community-related job responsibilities, such as washing dishes or cleaning the bathrooms. Due to the challenges of working in Antarctica, no guarantee can be made regarding the duties, location, or duration of work. The objective is to support science, maintain the station, and ensure the well-being of all station personnel. SAFETY The USAP is committed to safe work practices and safe work environments. There is no operation, activity, or research worth the loss of life or limb, no matter how important the future discovery may be, and all proactive safety measures shall be taken to ensure the protection of participants.

Improving Monitoring and Control of the Krill Fishery
CCAMLR-XXV/BG xx October 2006 Original: English Agenda Item 4, 7 & 10 IMPROVING MONITORING AND CONTROL OF THE KRILL FISHERY THE ANTARCTIC AND SOUTHERN OCEAN COALITION (ASOC) _______________ This paper is presented for consideration by CCAMLR and may contain unpublished data, analyses, and/or conclusions subject to change. Data contained in this paper should not be cited or used for purposes other than the work of the CCAMLR Commission, Scientific Committee, or their subsidiary bodies without the permission of the originators/owners of the data. IMPROVING MONITORING AND CONTROL OF THE KRILL FISHERY I. Introduction – CCAMLR and krill Ecosystem management of Antarctic krill (Euphausia superba) is a central task for CCAMLR. The Scientific Committee, through its Working Group on Ecosystem Monitoring and Management (WG- EMM), is developing management procedures on krill aimed at ensuring that ecological relationships between harvested, dependent and related populations are maintained, according to Article II 3 (b) of the Convention. In addition, CCAMLR’s Ecosystem Monitoring Program (CEMP) provides information on the status of the different components of the ecosystem to be incorporated into these management procedures. Regrettably, the quality and magnitude of CCAMLR’s scientific work on krill is rarely matched by action at the Commission level to provide the necessary tools to allow adequate monitoring and control of the fishery. A review of the reports of the Scientific Committee and the Commission from the past thirteen years has been recently conducted in order to assess the profile of krill-related discussions in their respective agendas. Discussions of krill and toothfish (Dissostichus spp.), currently the highest profile species under CCAMLR management, were compared.

Public Information Leaflet HISTORY.Indd
British Antarctic Survey History The United Kingdom has a long and distinguished record of scientific exploration in Antarctica. Before the creation of the British Antarctic Survey (BAS), there were many surveying and scientific expeditions that laid the foundations for modern polar science. These ranged from Captain Cook’s naval voyages of the 18th century, to the famous expeditions led by Scott and Shackleton, to a secret wartime operation to secure British interests in Antarctica. Today, BAS is a world leader in polar science, maintaining the UK’s long history of Antarctic discovery and scientific endeavour. The early years Britain’s interests in Antarctica started with the first circumnavigation of the Antarctic continent by Captain James Cook during his voyage of 1772-75. Cook sailed his two ships, HMS Resolution and HMS Adventure, into the pack ice reaching as far as 71°10' south and crossing the Antarctic Circle for the first time. He discovered South Georgia and the South Sandwich Islands although he did not set eyes on the Antarctic continent itself. His reports of fur seals led many sealers from Britain and the United States to head to the Antarctic to begin a long and unsustainable exploitation of the Southern Ocean. Image: Unloading cargo for the construction of ‘Base A’ on Goudier Island, Antarctic Peninsula (1944). During the late 18th and early 19th centuries, interest in Antarctica was largely focused on the exploitation of its surrounding waters by sealers and whalers. The discovery of the South Shetland Islands is attributed to Captain William Smith who was blown off course when sailing around Cape Horn in 1819.
