Abstract The differential distribution of diatoms and dinoflagellates in the Bay La Paz, Gulf California, Mexico, was analyzed summer 2009, when a cyclonic eddy confined bay dominated circulation. An uplift nutricline drove high concentrations nutrients to euphotic layer. A phytoplankton observed be associated with eddy: there an abundance close center eddy, whereas were more abundant at periphery. significant inverse correlation (R = −0.62, p < 0.002) found between temperature 25 m depth...
This study examines the vertical assemblages of holoplanktonic mollusks (Pteropoda and Pterotracheoidea) in Campeche Canyon, southern Gulf Mexico, during a “Nortes” season (February 21–28, 2011) explores their relationship with hydrography geostrophic circulation pattern. High-resolution hydrographic data were acquired multidisciplinary research cruise 48 stations. Zooplankton samples collected at 24 stations from four depths (10, 50, 100, 200 m) using multiple open/closed net system. The...
Physical and biological data were gathered over the Campeche Canyon area, Gulf of Mexico, in summer 1999. These include hydrographical meteorological parameters, oxygen content, as well as, at some oceanographic stations, suspended particulate matter (SPM), chlorophyll‐ a , vivo natural fluorescence profiles. Dry air from east set up latent heat flux that ranged 50 to 300 Wm −2 . The wind mixed layer (ML) was isothermal averaged 40 m thick, but with noticeable increase supersaturation toward...
During 2015–2016, a strong El Niño event, nicknamed the "Godzilla Niño," occurred in Pacific Ocean. Using satellite imagery, this article we assess impacts of event on sea-surface temperature and chlorophyll-a concentrations southern Gulf California. Daily images temperatures were obtained by from Moderate Resolution Imaging Spectroradiometer for period January 2013 to December 2017. A circular area ≈ 46.8 km diameter central part gulf was selected evaluate monthly variation both parameters....
This study evaluated the ingestion of microplastics (MP) by copepods in Terminos Lagoon (TL), a RAMSAR-listed site southern Gulf Mexico. The evaluation was carried out two contrasting seasons 2022, as follows: dry (April) and rainy (October). Copepods were collected using conical plankton net (mesh size 200 μm). In laboratory, pool all pelagic adult copepod taxa picked, MP inside organisms extracted, classified, photographed traditional optical scanning electron microscopy. A total 268...
La simulación de la circulación dentro Bahía Campeche es efectuada mediante un modelo hidrodinámico no lineal gravedad reducida. Las ecuaciones son resueltas numéricamente sobre una malla espacial uniforme, descentrada y 30 km resolución. fuentes perturbadoras los flujos a través del canal Yucatán Estrecho Florida. Los resultados indican presencia giros ciclónicos en cuales se desplazan hacia el oeste.
Environmental characteristics of the fluvial–deltaic–lagoon–estuarine system Palizada River were determined by assessment physical, environmental and hydrological variability. information comprised daily time series precipitation (1971–85), Usumacinta discharge (1948–94), sea level (1956–91) wind patterns (1984–87). Hydrology was studied weekly measurement salinity, transparency,temperature, dissolved oxygen pH at 18 stations during 19 months (September 1985 to March 1987). Water temperature...
Eddies and fronts created by geostrophic balance between counter-rotating currents are hydrodynamic processes that concentrate or dilute plankton suspended material physical of accumulation, retention, dispersion. Over Campeche Canyon, in the southern Gulf Mexico, observations revealed an anticyclonic eddy, a cyclonic current off continental shelf, associated thermal front their common boundary. Along this there was high Trichodesmium spp. occurrence. Three water masses were found upper 120...
This paper reports the temperature, salinity and sigma-t distributions at surface, 10 30 m depth, derived from data obtained in autumn of 1987 southern part Bay Campeche, as well density distribution along two cross sections which intersect near most important river system region. Based on field data, driven currents vertical stratification were estimated, latter by means potential energy anomaly. A strong haline gradient, that dominates is associated with discharge rivers region, was...
The sediment distribution in the southern Bay of Campeche is mainly governed by wind-induced currents and mesoscale cyclonic eddies. An increase grain size toward sea attributed to presence a convergence zone that sorts sediments from heavier lighter. A small anticyclonic eddy near coast leads concentration westward Grijalva-Usumacinta River. We combined current profiles charts magnetic susceptibility within with hydrodynamic numerical model elucidate major sedimentary units Southern...
The present study assesses the impact of a dipole on abundance and distribution phytoplankton groups as well chlorophyll-a concentration in Bay La Paz, Gulf California, Mexico. Based situ observations obtained multidisciplinary research cruise during summer 2008, mesoscale (cyclone-anticyclone) was observed; cyclone had ∼25 km diameter tangential speed ∼45 cm s−1, while anticyclone ∼15 ∼40 s−1. Strong gradients conservative temperature density were observed between both structures,...
