PRELIMINARY ESTIMATION OF PENGUIN BREEDING ABUNDANCE AT SPATIAL-SCALES OF RELEVANCE TO CCAMLR: INCORPORATING UNCERTAINTY IN COUNT DATA
Abstract: One recommendation from the Predator Survey workshop was the undertaking of some ... immediate inter-sessional work to be reported to WG-EMM-08. The work to be undertaken included preliminary ... Antarctic data for Adélie penguins. It was recognised that the abundance estimates would not be corrected ... for availability (e.g. nest failure) and hence would to some extent be biased estimates of the ...

An attempt to derive a composite index of abundance from acoustic surveys and fishery data
Abstract: Maps of krill (Euphausia superba) density derived from acoustic survey data and the ... distribution of fishing effort in the Chilean krill fishery indicate an area of high krill density wrapping ... around the northwestern end of Elephant Island during the austral summer of 1992. In this area, the ... operations are limited by processing efficiency rather than availability of krill. Analysis of the acoustic ...
