    Abstract

    A suite of CEMP and non-CEMP parameters collected at Admiralty Bay and Cape Shirreff, South Shetland Islands, Antarctica were analysed to assess the characteristics of the individual parameters, and their relationships to krill abundance and ice cover indices for the period 1978-2003. Results of the analyses are presented in a series of 6 Tables, following the outline of a Draft paper by K.Reid for similar analyses at South Georgia. The tabular data include:
    1. Table 1. A list of the penguin performance indices collected at the two sites
    2. Table 2. Data on annual variability in krill biomass density, annual sea ice cover and the relationship between these two measures for the period 1992-2002.
    3. Table 3. Characteristics of the predator performance indices.
    4. Table 4. A linear regression of the relationships between predator indices and ice cover
    5. Table 5. The relationships between predator indices and krill biomass presented as a linear regression for both Admiralty Bay and Cape Shirreff and as an exponential regression for the longer Admiralty Bay time series data.
    6. Table 6. A summary of the R2 values for all indices by seasons and species
