This project will quantify the impact of the climate warming on seabirds. The study area is in South Georgia in the South Atlantic with the largest and most diverse seabird colonies in the world. Detecting and understanding how physics and biology interact to bring positive or negative population changes to seabirds has long challenged scientists. The team in this project hypothesizes that 1) Cold water seabird species decline while warm water species increase due to ocean warming observed in the last 30 years; 2) All species decrease with ocean warming, affecting how they interact with each other and in doing so, decreasing their chances of survival; and 3) Species profiles can be predicted using multiple environmental variables and models. To collect present-day data to compare with observations done in 1985, 1991 and 1993, 2 cruises are planned in the austral winter; the personnel will include the three Principal Investigators, all experienced with sampling of seabirds, plankton and oceanography, with 2 graduate and 5 undergraduate students. Models will be developed based on the cruise data and the environmental change experienced in the last 30 years. The research will improve our understanding of seabird and marine mammal winter ecology, and how they interact with the environment. This project benefits NSF\u0027s goals to expand the fundamental knowledge of Antarctic systems, biota, and processes. The project will provide an exceptional opportunity to teach polar field skills to undergraduates by bringing 5 students to engage in the research cruises. To further increase polar literacy training and educational impacts, broader impacts include the production of an educational documentary that will be coupled to field surveys to assess public perceptions about climate change. \r\n\r\nPart II: Technical description: \r\nOcean warming in the western Antarctic Peninsula and Scotia Sea in winter is among the highest worldwide. Based on previous work, the Principal Investigators in this project want to test the hypothesis that warming would have decreased seabird abundance and species associations in the South Georgia region of the South Atlantic. A main premise of this proposal is that because of marine environmental change, the structure of the seabird communities has also changed, and potentially in a manner that has diminished the mutually beneficial dynamics of positive interactions, with subsequent consequences to fitness and population trends. The study is structured by 3 main objectives: 1) identify changes in krill, bird and mammal abundance that have occurred from previous sampling off both ends of South Georgia during winter in 1985, 1991 and 1993, 2) identify pairings of species that benefit each other in searching for prey, and quantify how such relationships have changed since 1985, and 3) make predictions about how these changes in species pairing might continue given predicted future changes in climate. The novelty of the approach is the conceptual model that inter-species associations inform birds of food availability and that the associations decrease if bird abundance decreases, thus warming could decrease overall population fitness. These studies will be essential to establish if behavioral patterns in seabird modulate their response to climate change.

Help on the Results MapX
This window can be dragged by its header, and can be resized from the bottom right corner.
Clicking the Layers button - the blue square in the top left of the Results Map - will display a list of map layers you can add or remove
from the currently displayed map view.
The Results Map and the Results Table
- The Results Map displays the centroids of the geographic bounds of all the results returned by the search.
- Results that are displayed in the current map view will be highlighted in blue and brought to the top of the Results Table.
- As the map is panned or zoomed, the highlighted rows in the table will update.
- If you click on a centroid on the map, it will turn yellow and display a popup with details for that project/dataset - including a link to the landing page. The bounds for the project(s)/dataset(s) selected will be displayed in red. The selected result(s) will be highlighted in red and brought to the top of the table.
- The default table sorting order is: Selected, Visible, Date (descending), but this can be changed by clicking on column headers in the table.
- Selecting Show on Map for an individual row will both display the geographic bounds for that result on a mini map, and also display the bounds and highlight the centroid on the Results Map.
- Clicking the 'Show boundaries' checkbox at the top of the Results Map will display all the bounds for the filtered results.
Defining a search area on the Results Map
- If you click on the Rectangle or Polygon icons in the top right of the Results Map, you can define a search area which will be added to any other search criteria already selected.
- After you have drawn a polygon, you can edit it using the Edit Geometry dropdown in the search form at the top.
- Clicking Clear in the map will clear any drawn polygon.
- Clicking Search in the map, or Search on the form will have the same effect.
- The returned results will be any projects/datasets with bounds that intersect the polygon.
- Use the Exclude project/datasets checkbox to exclude any projects/datasets that cover the whole Antarctic region.
