[ Update this Record ]

Summary

Abstract: A vegetation/land cover raster digital data set for the entire
National Petroleum Reserve in Alaska (NPR-A) was generated from
Landsat multispectral data sets. Included are eleven categories
of vegetation and land cover which are derived from all or
portions of 10 Landsat MSS scenes. The data set covers all or
part of thirteen 1:250,000-scale topographic ...

Taken from the 2009-2010 Progress Report:
Variations to work plan or objectives:
An aerial survey of the Vestfold Hills ... and Rauer Islands was conducted in November 2009 to collect data on the distribution and abundance of Adelie penguins in the areas around Davis. This supports one of the projects stated goals of expanding the spatial scale of monitoring, and involved taking photographs from a helicopter along pre-defined transects. Counts from aerial photographs will enable an assessment of the current distribution of colonies throughout the Vestfold Hills and Rauer Islands. Density and abundance will also be assessed providing population estimates. Current estimates will be compared with aerial photography through the same region in previous decades, enabling an assessment of changes in the distribution and abundance of the meta-population. Planned ground surveys of islands off Davis were performed in November 2009 (Gardener Island). Aerial photography of the Adelie penguin colonies surveyed from the ground in a small section of Gardner island enabled an assessment of the accuracy of counts gained from both survey methods. Preliminary results from this small trial indicate considerable undercounting from aerial photos, and further assessment of bias may be needed in 2010/11.

We propose to expand the snow petrel monitoring program to include (1) measurement of breeding success from mountain sites inland from Mawson, (2) a regional survey of the snow petrel population across the islands in the Kista Strait off Mawson, (3) modifying existing methods of nest checking for improved measurement of breeding success, and (4) identifying the relationship between parental quality and habitat quality.

Field work:
This season we performed a count of Adelie penguin sub-colonies on Gardener Island off Davis to ground truth aerial photography surveys. Ground surveys were also performed at a number of islands within the Rookeries group to the west of Mawson, and at the Robinson Islands the east of Mawson, to estimate population size and contribute to an assessment of temporal variation in abundance. Local islands around Mawson (Verner, Welch, Petersen and Klung) were also visited to count adults and / or chicks, and to maintain and download the automatic cameras installed on each island. The detailed monitoring program of Adelie penguins at Bechervaise Island, a CEMP long-term monitoring site, was continued and achieved all planned objectives. These included arrival counts, male and female attendance counts, as well as egg and chick counts to estimate hatching and breeding success. Satellite transmitters were deployed on 15 fledging Adelie penguins to track their winter foraging range.

Work on flying seabirds included surveys on numerous islands within the Kista Strait off Mawson, and the Robinson group east of Mawson. Double-observer surveys were performed at all visited sites to assess the detectability of crevice nesting species (snow petrels and Wilson's storm petrels). Regular checks of a large sample of snow petrel nest on Bechervaise island provided data on the proportion of nests occupied, nest attendance rates, hatching success and breeding success.

Laboratory activity/analysis:
CCAMLR monitoring data are processed and submitted to CCAMLR in the winter following each field season. Analysis of population survey, breeding success, foraging and survival data is continually underway as evidenced by the many recent publications.
