addemog lterpal9899 13oct98 - 23feb99 Adelie Penguin demography during the 98-99 season. Data files record breeding population size and overwinter survival, all sightings of previously flipper banded penguins, and the number and sequence of flipper bands applied each season. censusxx.dat year/month/day, island, colony, number of breeding pairs, seenxx.dat year/month/day, island, colony number, band number, breeding status, position within colony, sex, bandsxx.dat year/month/day, island, colony number, band number, Unless prevented by weather, data on sightings of banded penguins are based on sampling every two days. Data in the other files are based on single sampling events (censuses) at specific times during the season. Data are obtained in accordance with the CEMP Standard Methods (CCAMLR 1992), noting the following exceptions: Censuses to determine breeding population size are done as close to peak egg laying as possible in accordance with the protocol, but only incubating birds are censused. The application of new bands is annually limited to 500 rather than 1500 chicks. The search effort to detect returning, previously banded penguins is standardized by involving two people that search every colony on Humble Island every two days during the entire length of the field season. The experimental design is based on the CEMP Standard Methods (CCAMLR 1992) for determining breeding population size and annual survival and recruitment.

Key to acronyms and abbreviations used in pal-lter seabird databases. All data are initially recorded in field notebooks. Quality assurance is determined during two subsequent stages. The first is when data are moved from field notebooks to data sheets; the second is when data are moved from data sheets to databases. Core measurments available two years after the season.
