CCAMLR Ecosystem Monitoring Program (CEMP) at Admiralty Bay (ADB) for Adelie (PYD), chinstrap (PYN) and gentoo (PYP) penguins

Admiralty Bay is located on the eastern side of King George Island in the South Shetland Islands (Subarea 48.1). The USA has a long-term research program in this area and operates the Pieter J. Lenie Field Station (also known as Copacabana). Adelie, chinstrap and gentoo penguins have been monitored here and data has been collected on the following parameters for each species:

**Adelie**:

Breeding population size

Duration of incubation shift

Duration of foraging

Breeding success

Chick weight at fledging

Chick diet

Breeding chronology

**Chinstrap**:

Breeding population size

Duration of incubation shift

Breeding success

Chick weight at fledging

Chick diet

**Gentoo**:

Breeding population size

Duration of foraging

Breeding success

Chick weight at fledging

Chick diet

Breeding chronology

The data collected varies between years but monitoring for each species has been carried out almost every year since 1978.

**Purpose of CEMP:**
In order to provide information of the effects of fishing on dependent species, CCAMLR set up the CCAMLR Ecosystem Monitoring Program (CEMP) in 1989. The two aims of CEMP are to:

1) Detect and record significant changes in critical components of the marine ecosystem within the Convention Area, to serve as a basis for the conservation of Antarctic marine living resources.

2) Distinguish between changes due to harvesting of commercial species and changes due to environmental variability, both physical and biological.
