Skeletal measurements from fossil seals from the western Ross Sea, Antarctica Dataset Description: <p><strong>These data are published and discussed in:</strong><br />
Brault, E. (2017). An Examination of the Ecological and Oceanographic Effects of Mid-to-Late Holocene Climate Changes on the Ross Sea Ecosystem. UC Santa Cruz. ProQuest ID: Brault_ucsc_0036E_11435. Merritt ID: ark:/13030/m5dg1n5d. Retrieved from&nbsp;<a href="https://escholarship.org/uc/item/99s5j3fk" target="_blank">https://escholarship.org/uc/item/99s5j3fk</a></p> Methods and Sampling: <p><strong>Sample collection:</strong><br />
Fossil seal samples were collected during the austral summers of 2005/06, 2006/07, 2012/13, and 2013/14 in Antarctica in the Dry Valleys and along the Victoria Land Coast (especially Inexpressible Island on Terra Nova Bay), Antarctica. Since this region experiences unusually dry and cold conditions, carcasses and bones are well-preserved, potentially for several thousand years, and therefore have unchanged isotopic compositions in most cases. The sampled species were crabeater, Weddell, leopard, and southern elephant seals. Latitude and longitude of each specimen was recorded and several photographs were taken of each specimen. Bone and carcass weathering states were determined. Several samples were gathered from the specimens. Most commonly, bone was collected, followed by skin and fur; nails, teeth, and whiskers were not frequently available for sampling, but taken when possible. Samples were collected with ethanol-cleaned tools, stored in Whirl-Pak bags, and refrigerated (~4 °C) when we returned from the field.</p>
<p><strong>Species identification and radiocarbon analysis:</strong><br />
When possible, species identification of each specimen was conducted in the field via examination of teeth or bones with features unique to the four pinniped species. Additionally, the team at the University of Durham in the United Kingdom extracted and analyzed DNA from many specimens (described in <a href="https://www.bco-dmo.org/dataset/732524" target="_blank">Fossil Seal Bulk Isotopes 14C</a>) to confirm or establish the species identification. Full details on radiocarbon dating are supplied in that sheet as well.</p>
<p>Most skeletal measurement were made in the field with a steel tape measure or calipers (for tooth row length). In many cases, parts of bones were obscured by tissue, so measurements are approximate. Refer to the <a href="http://datadocs.bco-dmo.org/docs/Southern_Ocean_Pinnipeds/data_docs/732661/1/Bone_Measurement_Guide.pdf">Bone Measurment Guide</a> (PDF).</p>

Collaborative Research: Exploring the Vulnerability of Southern Ocean Pinnipeds to Climate Change - An Integrated Approach
<p><em>NSF abstract:</em><br />
Building on previously funded NSF research, the use of paleobiological and paleogenetic data from mummified elephant seal carcasses found along the Dry Valleys and Victoria Land Coast in areas that today are too cold to support seal colonies (Mirougina leonina; southern elephant seals; SES) supports the former existence of these seals in this region. The occurrence and then subsequent disappearance of these SES colonies is consistent with major shifts in the Holocene climate to much colder conditions at the last ~1000 years BCE).</p>
<p>Further analysis of the preserved remains of three other abundant pinnipeds ? crabeater (Lobodon carciophagus), Weddell (Leptonychotes weddelli) and leopard (Hydrurga leptonyx) will be studied to track changes in their population size (revealed by DNA analysis) and their diet (studied via stable isotope analysis). Combined with known differences in life history, preferred ice habitat and ecosystem sensitivity among these species, this paleoclimate proxy data will be used to assess their exposure and sensitivity to climate change in the Ross Sea region during the past ~1-2,000 years</p>

<p><strong>Sample collection:</strong><br />
Fossil seal samples were collected during the austral summers of 2005/06, 2006/07, 2012/13, and 2013/14 in Antarctica in the Dry Valleys and along the Victoria Land Coast (especially Inexpressible Island on Terra Nova Bay), Antarctica. Since this region experiences unusually dry and cold conditions, carcasses and bones are well-preserved, potentially for several thousand years, and therefore have unchanged isotopic compositions in most cases. The sampled species were crabeater, Weddell, leopard, and southern elephant seals. Latitude and longitude of each specimen was recorded and several photographs were taken of each specimen. Bone and carcass weathering states were determined. Several samples were gathered from the specimens. Most commonly, bone was collected, followed by skin and fur; nails, teeth, and whiskers were not frequently available for sampling, but taken when possible. Samples were collected with ethanol-cleaned tools, stored in Whirl-Pak bags, and refrigerated (~4 °C) when we returned from the field.</p>
<p><strong>Species identification and radiocarbon analysis:</strong><br />
When possible, species identification of each specimen was conducted in the field via examination of teeth or bones with features unique to the four pinniped species. Additionally, the team at the University of Durham in the United Kingdom extracted and analyzed DNA from many specimens (described in <a href="https://www.bco-dmo.org/dataset/732524" target="_blank">Fossil Seal Bulk Isotopes 14C</a>) to confirm or establish the species identification. Full details on radiocarbon dating are supplied in that sheet as well.</p>
<p>Most skeletal measurement were made in the field with a steel tape measure or calipers (for tooth row length). In many cases, parts of bones were obscured by tissue, so measurements are approximate. Refer to the <a href="http://datadocs.bco-dmo.org/docs/Southern_Ocean_Pinnipeds/data_docs/732661/1/Bone_Measurement_Guide.pdf">Bone Measurment Guide</a> (PDF).</p>

PI Supplied Instrument Name: steel tape measure or calipers PI Supplied Instrument Description:Most skeletal measurement were made in the field with a steel tape measure or calipers (for tooth row length). In many cases, parts of bones were obscured by tissue, so measurements are approximate. Instrument Name: Measuring Tape Instrument Short Name: Instrument Description: A tape measure or measuring tape is a flexible ruler. It consists of a ribbon of cloth, plastic, fibre glass, or metal strip with linear-measurement markings. It is a common tool for measuring distance or length.
