The Estero de Punta Banda, B.C., Mexico as a link in the "Pacific Flyway": Abundance of shorebirds

open access: yesCiencias Marinas, 2021
Thirteen shorebird species and 5683 individuals were recorded at Estero Punta Banda from October 1988 to April 1989 in three soft-bottom habitats bordering the northern tip of the sand bar (open beach; terminal beach; mud-flats) and a semi-protected ...

Numerical modeling of seasonal and mesoscale hydrography and circulation in the Mexican Central Pacific

open access: yesCiencias Marinas, 2012
Based on results from a ROMS numerical model, the dynamics of the Mexican Central Pacific was studied during three years (2003–2005). The model reproduces the mean and seasonal variability of sea surface temperature, as well as mesoscale eddies and ...

Genetic connectivity of the endangered brown sea cucumber Isostichopus fuscus in the northern Gulf of California revealed by novel microsatellite markers

open access: yesRevista Mexicana de Biodiversidad, 2018
Isostichopus fuscus is an economically important sea cucumber that has been highly exploited along its distribution range in the eastern Pacific. The significant population decline is responsible for its listing as endangered in the IUCN Red List ...

The Gulf of California is a source of carbon dioxide to the atmosphere

open access: yesCiencias Marinas, 2013
Water exchange between the Gulf of California and the Pacific Ocean has a significant vertical component (VCWE). Surface (0–200 m) gulf water flows out into the Pacific Ocean and deep (200–600 m) water flows into the gulf.

Annual and semiannual variations of phytoplankton biomass and production in the central Gulf of California estimated from satellite data

open access: yesCiencias Marinas, 2013
Surface waters of the Midriff Islands region of the Gulf of California persistently have the lowest temperatures (SST) and the highest nutrient concentrations of all surface waters of the gulf. The purpose of this work was to characterize the annual and

Temperature, salinity, nutrients and chlorophyll a in coastal waters of the Southern California Bight

open access: yesCiencias Marinas, 2001
The seasonal variability of dissolved inorganic nutrients (phosphates, PO–34; nitrates, NO–3; nitrites, NO–2) and chlorophyll a was studied during five surveys in nearshore waters of the southern region of the Southern California Bight (SCB).

Micromollusk families in 2 contrasting seasons in Bahia de los Angeles, Gulf of California, Mexico

open access: yesCiencias Marinas, 2023
Marine mollusks provide important ecosystem services. They create habitats for benthic organisms, filter water, biodeposit organic carbon in the seafloor, and serve as food sources for other organisms. Studies of mollusk diversity require time-consuming

Effect of the oxygen minimum zone on the second chlorophyll maximum

open access: yesCiencias Marinas, 2009
Field data collected during June 2005 were used to determine the relationship between the second fluorescence maximum (FMax), the top of the oxygen minimum zone (OMZ), and physical processes (coastal currents, eddies, and upwelling) in the northern ...

Mitochondrial variability of dolphinfish Coryphaena hippurus populations in the Pacific Ocean

open access: yesCiencias Marinas, 2006
Patterns of genetic structure among marine populations involve a variety of dispersal mechanisms and spatial scales. Pelagic species, such as the dolphinfish Coryphaena hippurus, epitomize the open and continuous nature of the marine environment due to ...
