Early conservation benefits of a de facto marine protected area at San Clemente Island, California

Marine Conservation in the Azores: Evaluating Marine Protected Area Development in a Remote Island Context

In the Archipelago of the Azores, over 110,000 km2 of marine areas presently benefit from some form of protection, including a suite of coastal habitats, offshore areas, seamounts, hydrothermal vents, and large parcels of mid-ocean ridge. These areas are integrated in the recently established network of marine protected areas (MPAs), which stands as the cornerstone of Azorean marine conservatio...

Dietary Overlap of an Alien and Native Carnivore on San Clemente Island, California

Uranium-series age of the Eel Point terrace, San Clemente Island, California

Uranium-series analysis of the coral Allopora californica Verrill from the 2nd, 32-m Eel Point terrace on San Clemente Island, California, has yielded an age of 127,000 k 7,000 yr. The Eel Point terrace is thus correlative with numerous terrace localities on the southern California mainland, with coral reefs on Barbados and New Guinea dated about 120,000 yr, and with substage 5e of the marine o...

A 50 year comparison of ambient ocean noise near San Clemente Island: a bathymetrically complex coastal region off Southern California.

Repeated ocean ambient noise measurements at a shallow water (110 m) site near San Clemente Island reveal little increase in noise levels in the absence of local ships. Navy reports document ambient noise levels at this site in 1958-1959 and 1963-1964 and a seafloor recorder documents noise during 2005-2006. When noise from local ships was excluded from the 2005-2006 recordings, median sound le...

Seasonal Changes of Bioluminescence in Photosynthetic and Heterotrophic Dinoflagellates at San Clemente Island

A significant portion of bioluminescence in all oceans is produced by dinoflagellates. Numerous studies have documented the ubiquitous distribution of bioluminescent dinoflagellates in near surface waters (Seliger et al., 1961; Yentsch and Laird 1968; Tett 1971; Tett and Kelly 1973). The number of bioluminescent species and their relative abundance change temporally, with depth, and geographica...
