Airborne dust transport to the eastern Pacific Ocean off southern California: Evidence from San Clemente Island

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...

Increases in deep ocean ambient noise in the Northeast Pacific west of San Nicolas Island, California.

Recent measurement at a previously studied location illustrates the magnitude of increases in ocean ambient noise in the Northeast Pacific over the past four decades. Continuous measurements west of San Nicolas Island, California, over 138 days, spanning 2003-2004 are compared to measurements made during the 1960s at the same site. Ambient noise levels at 30-50 Hz were 10-12 dB higher (95% CI =...

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...

Seasonal Variations of Upper Ocean Transport from the Pacific to the Indian Ocean via Indonesian Straits*

Seasonal variations of upper-ocean mass transport between the Pacific and Indian Oceans via the Indonesian Throughflow (ITF) are examined using numerical experiments with a 11⁄2-layer, reduced-gravity model forced with specific climatological winds. The model ITF transport, computed as a sum of through-strait transport, has an annual range of more than 8 Sv (an annual harmonic of amplitude 4.2 ...
