CCAMLR Ecosystem Monitoring Program (CEMP) at Esperanza Station (ESP) for Adelie penguins (PYD)

It is located on the north of the Antarctic Peninsula at Hope Bay, Trinity Peninsula (Subarea 48.1). A large **Adelie penguin** colony has been monitored since 1994, and data has been collected on the following parameters: Adult weight on arrival Duration of incubation shift Breeding population size Breeding success Chick weight at fledging Chick diet **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.
