California Seabird Ecology Study. Volume 1. Feeding Ecology of California Nesting Seabirds

摘要

The studies comprise three elements designed to augment MMS' ability to predict impacts to nesting seabirds that might result from exploration and production of oil and gas on the California Outer Continental Shelf. The first element consisted of a synthesis of existing literature and an analysis of several unpublished sources of information on the feeding ecology of ten seabird species whose aggregate nesting populations at Castle Rock, the Farallon Islands, or the Channel Islands exceeded 2,000 individuals. Analyses of satellite images of ocean surface temperature and color to determine recurrence, persistence, and other aspects of coastal upwelling formed the second element. Based on these studies, the third element, a field study of feeding ecology of Common Murres and Cassin's Auklets in central California, was conducted in 1985. The present volume brings together the findings of the first and third elements, while the companion volume presents results of studies of satellite imagery.
