Coastal Transport Processes Affecting Inner-Shelf Ecosystems in the California Current System
California Current System Processes Affecting Inner-Shelf Ecosystems
2015/7/16
Wind-driven upwelling is weak and intermittent in the Southern California Bight, a region sheltered from the strong, prevailing equatorward winds typical of most of the California Current System. Thus...

15-year analysis of blue whale range off California finds conflict with shipping lanes
15-year analysis blue whale range California finds conflict shipping lanes
2014/8/14
A comprehensive 15-year analysis of the movements of satellite-tagged blue whales off the West Coast of the United States found that their favored feeding areas are bisected by heavily used shipping l...
Gill surface area and metabolic enzyme activities of demersal fishes associated with the oxygen minimum zone off California
Gill surface area metabolic enzyme activities demersal fishes associated oxygen minimum zone California
2014/4/2
Metabolic enzyme activities and gill surface areas were measured across 10 species of demersal fishes from Monterey Canyon, California, which features a prominent oxygen minimum zone (OMZ). Comparison...

Turbulent mixing induced by nonlinear internal waves in Mono Lake, California
Turbulent mixing induced nonlinear internal waves Mono Lake California
2014/4/17
Describing the spatial and temporal occurrence of turbulent mixing and the mechanisms of turbulence production are fundamental problems in physical limnology and oceanography. Here we present results ...
Role of oxidative stress in seasonal and daily vertical migration of three krill species in the Gulf of California
Role of oxidative stress seasonal
2014/4/17
Vertical distribution and abundance of three numerically dominant krill species (Nyctiphanes simplex,
Nematoscelis difficilis, and Euphausia eximia) were surveyed in the Gulf of California to underst...
The response of giant kelp (Macrocystis pyrifera) in southern California to low-frequency climate forcing
giant kelp southern California
2014/4/17
The nutrient climate on the inner shelf off southern California changed markedly across the 1976–1977 North
Pacific climate regime shift. With respect to giant kelp (Macrocystis pyrifera) canopies of...
Inorganic carbon and biological oceanography above a shallow oxygen minimum in the entrance to the Gulf of California in the Mexican Pacific
oxygen minimum Inorganic carbon
2014/4/16
The eastern Pacific intermediate oxygen minimum layer (OML) is particularly well-developed and shoals close
to the Mexican coast. We obtained hydrographic profiles including oxygen concentration [O],...
Population connectivity of the Olympia oyster in Southern California
Population connectivity the Olympia oyster Southern California
2014/4/16
The Olympia oyster is a useful model to study the population connectivity of estuarine invertebrates because it incorporates chemical information about the natal site into its shell before dispersal. ...

Upwelling systems natural acidity the ocean surface carbonate mineral aragonite sea water carbon dioxide ocean acidification
2015/7/6
Eastern boundary upwelling systems (EBUS) are naturally more acidic than most of the rest of the surface ocean. Observations of EBUS already show pH values and saturation states with regard to the car...
Multi-decadal shoaling of the euphotic zone in the southern sector of the California Current System
