  • The exact location of an Emperor Penguin Colony on Peterson Bank continually changes due to the changing ice conditions of where the colony is situated. The location confirmed on the 3rd of November 1994 on fast ice at Peterson Bank was 65.9333 S, 110.2 E, 41km NNW of Australia's Casey Station. The location was recorded by Ward Bremmers during a helicopter flight involved in the resupply operations from an ice-bound ship to Casey Station. The presence of chicks was confirmed on landing and an approximate count estimated chick numbers at 2000 with at least 1000 adults present. Many foraging animals were also observed in transit in the surrounding area. Approximately 100 dead chicks, ranging in age from a few weeks to 3 months old, were observed during a casual check in the immediate vicinity. The colony lies on fast ice amid grounded bergs in Peterson Bank. The surrounding icebergs are widely spaced (1-2km), so the colony site is relatively unsheltered from the prevailing easterly gales. The sea-ice thickness at the colony sites was 7-8m, suggesting the ice had been stable for the previous three or our seasons. However, during a second visit to the site on 24 December 1994, the ice at the colony site was breaking up, and 200 chicks in the process of moulting were observed drifting on a large ice floe. On the 24 of April in 1995, a large group of Adults on new ice amid grounded bergs in the Peterson Bank was sighted, suggesting that the colony was reforming.

  • Long term data sets are useful for identifying temporal changes in the abundance of breeding populations of Antarctic seabirds. This data set is one of only two long term data sets existing for Snow Petrels. The data set comprises records of snow petrel activity for up to 109 nests clearly marked on the colony of Reeve Hill (near Casey station)between 1984 and 2003. A map of the exact nests locations is available as Arcview shapefile. In the database, the following information was recorded in an Excel worksheet: - For each colony check: observer(s) name(s), date and time of the nests check, weather before and during observations - For each nest: 1/nests condition (whether filled with ice/snow or (partially) accessible) 2/activity level in the nests: presence/absence of birds, what sex if known, other signs of activity (footprints, guano, stomach oil) 3/presence of an egg or chick, live or failed 4/presence of old remnants in the nest(egg, chicks) 5/Any specific comments No data are available for years 1987-1988 and 1988-1989. Data are only available for the early part of the breeding season for 1991-1992, 1992-1993 and 1999-2000. The fields in this dataset are: Field Season Date Type of Observation Time start Nest Number Nest condition Old Remnants Activity Egg/Chick Comments
