It spends about four and half months per annum deep in Antarctic pack ice away from shore and stations, and thus is largely unavailable for study. This time includes preparation for the molt, and travel to the colony to breed, a time period in which great swings in body weight occur. This study will fill an important gap in what we know about the biology of the annual cycle of the emperor by examining the molt-post molt period. The P.I. proposes to traverse the Amundsen and Bellingshausen seas on the Oden, to locate and tag emperor penguins during the molt season. The objectives are to (1) Place satellite tags on 20 adult post molt birds to determine their route, rate of travel, and diving behavior as they return back to their breeding colonies, (2) Obtain an index of body condition, (3) Collect guano to determine the type of food consumed by emperor penguins in the region, (4) Conduct shipboard surveys to sight and plot the location and abundance of adult and juvenile birds on the ship\u0027s track. The PI hypothesizes that bird dives will be shallow during the initial post-molt phase, and that food will consist primarily of krill; that there will be differential dispersal of birds from the Ross Sea vs. Marie Byrd Land, with Ross Sea birds traveling farther; and that the greatest adult mortality occurs during the molt and early post molt period. Broader impacts include training of a post doc, a graduate student, and an aquarium volunteer. The P.I. also will present findings through a website, through public lectures, and in collaboration with the Birch aquarium.\n", "east": -155.296, "geometry": ["POINT(-163.969 -75.1715)"], "keywords": "Amundsen Sea; Biota; Oceans; Penguin; Sample/collection Description; Sample/Collection Description; Southern Ocean", "locations": "Amundsen Sea; Southern Ocean", "north": -72.55, "nsf_funding_programs": null, "persons": "Kooyman, Gerald", "project_titles": "Pre and post molt biology of emperor penguins - Oden trans - Ross / Amundsen Sea cruise", "projects": [{"proj_uid": "p0000325", "repository": "USAP-DC", "title": "Pre and post molt biology of emperor penguins - Oden trans - Ross / Amundsen Sea cruise"}], "repo": "USAP-DC", "repositories": "USAP-DC", "science_programs": null, "south": -77.793, "title": "Pre and Post Molt Biology of Emperor Penguins - Oden Trans - Ross / Amundsen Sea Cruise", "uid": "600149", "west": -172.642}, {"awards": "0528728 Vernet, Maria", "bounds_geometry": ["POLYGON((-69.08 -64.8,-68.632 -64.8,-68.184 -64.8,-67.736 -64.8,-67.288 -64.8,-66.84 -64.8,-66.392 -64.8,-65.944 -64.8,-65.496 -64.8,-65.048 -64.8,-64.6 -64.8,-64.6 -65.121,-64.6 -65.442,-64.6 -65.763,-64.6 -66.084,-64.6 -66.405,-64.6 -66.726,-64.6 -67.047,-64.6 -67.368,-64.6 -67.689,-64.6 -68.01,-65.048 -68.01,-65.496 -68.01,-65.944 -68.01,-66.392 -68.01,-66.84 -68.01,-67.288 -68.01,-67.736 -68.01,-68.184 -68.01,-68.632 -68.01,-69.08 -68.01,-69.08 -67.689,-69.08 -67.368,-69.08 -67.047,-69.08 -66.726,-69.08 -66.405,-69.08 -66.084,-69.08 -65.763,-69.08 -65.442,-69.08 -65.121,-69.08 -64.8))"], "date_created": "Sat, 01 Jan 2011 00:00:00 GMT", "description": "This collaborative study between the Desert Research Institute, the University of California, Santa Barbara (0529087; Robin Ross), and the University of California, San Diego (0528728; Maria Vernet) will examine the relationship between sea ice extent along the Antarctic Peninsula and the life history of krill (Euphausia superba), by developing, refining, and linking diagnostic datasets and models of phytoplankton decreases in the fall, phytoplankton biomass incorporation into sea ice, sea ice growth dynamics, sea ice algal production and biomass accumulation, and larval krill energetics, condition, and survival.

While this is true of all marine mammals, variation in the physical and biological environmental is particularly profound in the Southern Ocean. A basic understanding of the foraging behavior and habitat utilization of pelagic predators requires knowledge of this spatial and temporal variation, coupled with information of how they respond to these changes. Current understanding of these associations is primarily limited to population level studies where animal abundance has been correlated with oceanography. Although these studies are informative, they cannot provide insights into the strategies employed by individual animals nor can they provide insights into the spatial or temporal course of these interactions. Recent technological advances in instrumentation make it possible to extend an understanding beyond the simple linkage of prey and predator distributions with environmental features. The key to understanding the processes that lead to high predator abundance is the identification of the specific foraging behaviors associated with different features of the water column. This study will accomplish these objectives by combining accurate positional data, measures of diving and foraging behavior, animal-derived water-column temperature and salinity data, and available oceanographic data. This project will examine the foraging behavior and habitat utilization of two species of contrasting foraging ecology, the southern elephant seal, Mirounga leonina, and the crabeater seal, Lobodon carcinophagus in the Western Antarctic Peninsula, a region of strong environmental gradients. Although these two species are phylogenetically related, they utilize substantially different but adjacent habitat types. Southern elephant seals are predominantly pelagic, moving throughout the southern ocean, venturing occasionally into the seasonal pack ice whereas crabeater seals range throughout the seasonal pack ice, venturing occasionally into open water. The relationship of specific foraging behaviors and animal movement patterns to oceanographic and bathymetric features develop and test models of the importance of these features in defining habitat use will be determined along with a comparison of how individuals of each species respond to annual variability in the marine environment. The physical oceanography of the Southern Ocean is inherently complex as are the biological processes that are intrinsically linked to oceanographic processes. Significant resources are currently being directed toward developing mathematical models of physical oceanographic processes with the goals of better understanding the role that the Southern Ocean plays in global climate processes, predicting the responses of ocean and global scale processes to climate change, and understanding the linkages between physical and biological oceanographic processes. These efforts have been limited by the scarcity of oceanographic data in the region, especially at high latitudes in the winter months. This study will provide new and significant oceanographic data on temperature and salinity profiles in to further the understanding of the dynamics of the upper water column of west Antarctic Peninsula continental shelf waters.
