Abstract: The Retrospective Analysis of Antarctic Tracking Data (RAATD) is a Scientific Committee for Antarctic Research project led jointly by the Expert Groups on Birds and Marine Mammals and Antarctic Biodiversity Informatics, and endorsed by the Commission for the Conservation of Antarctic Marine Living Resources. RAATD consolidated tracking data for multiple species of Antarctic meso- and top-predators to identify Areas of Ecological Significance. These datasets and accompanying syntheses provide a greater understanding of fundamental ecosystem processes in the Southern Ocean, support modelling of predator distributions under future climate scenarios and create inputs that can be incorporated into decision making processes by management authorities. In this data paper, we present the compiled tracking data from research groups that have worked in the Antarctic since the 1990s. The data are publicly available through biodiversity.aq and the Ocean Biogeographic Information System. The archive includes tracking data from over 70 contributors across 12 national Antarctic programs, and includes data from 17 predator species, 4060 individual animals, and over 2.9 million observed locations.

The Future of Penguins Depends on Proactive Management of Current and Expected Threats (Vol. 6). Bachelor's thesis, , .
Abstract: Penguins face a wide range of threats. Most observed population changes have been negative and have happened over the last 60 years. Today, populations of 11 of the 18 penguin species are decreasing. Here we present a review that synthesizes details of threats faced by the world’s 18 species of penguins. We discuss alterations to their environment at both breeding sites on land and at sea where they forage. The major drivers of change appear to be climate, and food web alterations by marine fisheries. In addition, we also consider other critical and/or emerging threats, namely human disturbance near nesting sites, pollution due to oil, plastics and chemicals such as mercury and persistent organic compounds. Finally, we assess the importance of emerging pathogens and diseases on the health of penguins. We suggest that in the context of climate change, habitat degradation, introduced exotic species and resource competition with fisheries, successful conservation outcomes will require new and unprecedented levels of science and advocacy. Successful conservation stories of penguin species across their geographical range have occurred where there has been concerted effort across local, national and international boundaries to implement effective conservation planning.

Two Recent Massive Breeding Failures in an Adélie Penguin Colony Call for the Creation of a Marine Protected Area in D'Urville Sea/Mertz (Vol. 5). Bachelor's thesis, , .
Abstract: In the d’Urville Sea in East Antarctica, a population of roughly 20,000 pairs of Adélie penguins of Iles des Pétrels (Terre Adélie) has experienced two massive breeding failures, with no chick surviving the 2013-14 and 2015-16 breeding seasons. In both seasons the extent of sea ice in front of the colony persisted throughout the breeding cycle of the birds. The timing of sea-ice recession differed greatly between seasons and the absence of polynya in a crucial phase of the cycle were paramount in driving these failures. The change in the icescape in front of Ile des Pétrels following the calving of the Mertz glacier in 2010, together with increase in precipitations and changes in sea-ice firmness explain this situation and are discussed in the present manuscript. To prevent additional future impacts on this colony, like competition with fisheries for instance, we strongly support a scientific research zone in the d'Urville Sea – Mertz area, one of the three zones of proposed Marine Protected Area in East Antarctica to the Commission for the Conservation of Antarctic Marine Living Resources.

Yan Axel Gómez Coutouly, Kelly E. Graf, Angela K. Gore, Ted Goebel. (2019). Little Panguingue Creek: A c. 9600-Year-Old Prehistoric Knapping Workshop in the Nenana Valley, Central Alaska (Vol. 5). Bachelor's thesis, , .
Abstract: The Nenana Valley near Healy, Alaska, has been the site of many decades of prehistoric archaeological research focused on the late Pleistocene and early Holocene records. New research at the Little Panguingue Creek (LPC) site (HEA-038) provides us with important information about Pleistocene–Holocene human activities in the Nenana Valley foothills. This multi-component site is located on a Healy-aged glacial-outwash terrace, overlooking LPC. A new multi-year excavation program, begun in 2015, revealed a c. 9600 cal yr BP knapping workshop (hammerstones, cores, preforms, cortical spalls, tools, debitage, etc.) with a major microblade component dating from the final phase of the Denali complex, along with an older component dating to c. 11,150 cal yr BP. On-going research at the site will further our understanding of human technological, subsistence, and settlement organization in the Nenana Valley (and beyond) during the Pleistocene/Holocene transition. Here we present preliminary results of work accomplished so far.

Abstract: In Beringia, as in many other parts of the world, stone tools are the main diagnostic cultural artifact for understanding prehistoric societies. The analysis of lithic assemblages is the basis for establishing connections between sites and techno-complexes. Through highlighting major technological trends, archaeologists are able to interpret processes such as cultural continuity and migrations. Here we present a fine-grained analysis of two assemblages to perceive in detail the individuals behind the lithic productions, more specifically apprentice knappers. Although recognition of apprenticeship in a prehistoric context is not new, this is the first such study for Alaska and Beringia. We focus on two distinct assemblages with microblade technology: the late Pleistocene component of Swan Point CZ4b (Tanana valley) and the early Holocene component of Little Panguingue Creek C2 (Nenana valley), both in central Alaska.
