Latitudinal and archipelago effect on the composition, distribution, and abundance of zooplanktonic organisms in the Gulf of California

open access: yesOceanologia, 2023
The upper Gulf of California is one of the most energetic regions owing to its tidal range and strong tidal currents, making the upper gulf and the archipelago zone highly turbulent regions; the abundance of zooplankton should be associated with mixing ...

Three-dimensional connectivity during summer in the northern Gulf of California

open access: yesScientia Marina, 2016
Connectivity studies in the Gulf of California are an important tool for improving the use and management of the gulf’s natural resources. The goal of this work was to study the three-dimensional connectivity in the northern Gulf of California during two

Bathymetry and active geological structures in the Upper Gulf of California

open access: yesBoletín de la Sociedad Geológica Mexicana, 2009
Bathymetric surveys made between 1994 and 1998 in the Upper Gulf of California revealed that the bottom relief is dominated by narrow, up to 50 km long, tidal ridges and intervening troughs. These sedimentary linear features are oriented NW-SE, and run across the shallow shelf to the edge of Wagner Basin.

Upper-ocean circulation patterns in the northern Gulf of California, expressed in Ers-2 Synthetic Aperture Radar Imagery

open access: yesCiencias Marinas, 2001
ERS-2 Synthetic Aperture Radar (SAR) frames were collected over the northern Gulf of California during winter 1999. The frames, presented here as a single composite image (100 x 300 km), express a mesoscale meander or eddy-like feature, approximately 80

Barotropic background currents in the Gulf of California

open access: yesCiencias Marinas, 2003
 A field of barotropic background currents (BC) in the Gulf of California is constructed numerically. The definition of BC used here is based on suppositions about (i) the horizontal homogenization of potential vorticity in large-scale gyres, and (ii ...

Analysis of the corvina gulf fishery as a function of management actions in the Upper Gulf of California, Mexico

open access: yesLatin American Journal of Aquatic Research, 2017
The gulf corvina (Cynoscion othonopterus), is an endemic species of the Gulf of California, and its fishery is one of the most important in the Upper Gulf of California. Two dynamic biomass models (Schaefer & Pella-Tomlinson), were used to assess the state of the stock due to the lack of enough age data for a reliable full age-structured stock ...

Spatial segregation in eastern North Pacific skate assemblages. [PDF]

open access: yesPLoS ONE, 2014
Skates (Rajiformes: Rajoidei) are common mesopredators in marine benthic communities. The spatial associations of individual species and the structure of assemblages are of considerable importance for effective monitoring and management of exploited ...
