Abstract The past 2000 years have been crucial to evaluating climate models and their projections. We explored an artificial neural network (ANN) reconstruct (the 600 years) model the for coming decades. For reconstruction of air temperature (AT) sea surface (SST), time series instrumental data diatoms fluxes, contemporaneous preserved in a laminated sediment core from Alfonso Basin, were used train feedforward ANN (6 neurons AT 14, 14 SST). demonstrated that ANNs advantage simplifying...
Quantification of photosynthetic efficiency and productive capacity the phytoplankton community was objective surveys that were conducted in December 2005, May August 2006; February, November 2007 Bahía de La Paz (Cuenca Alfonso).Samples water collected from 7 levels surface irradiance (100, 55, 33, 10, 3, 1 0.1%), euphotic zone (Z eu ).In situ primary production estimations performed by 14C assimilation methodology.There 2 basic ratios patterns; one with subsurface maxima during February...
Abstract We conducted a study from January 2002 to February 2008 on silicoflagellate fluxes in Alfonso Basin at the entrance Gulf of California. Thirteen taxa were identified sediment trap samples, with Octactis pulchra as dominant species. Total flux climatology reached maximum value 5×10 6 skeletons m -2 day -1 December and then sharply decreased minimum (2.3×10 3 ) concurrently climatological sea surface temperature (SST) minimum. Subsequently, there was positive trend second relative...
Understanding the susceptibility of coastal ecosystems to nutrient loads from anthropogenic sources and extent eutrophication in subtropical tropical estuaries is still a challenge. This study assessed Guaymas Bay, lagoon that receives nutrient-rich urban wastewater discharges. Eutrophication was evaluated by means Assessment Estuarine Trophic Status model. Our results showed trophic status Bay “good.” It important consider that: (1) dissolved oxygen chlorophyll levels observed are...

As part of an ongoing monitoring study phytoplankton in coastal lagoons on the east side Gulf California, Pyrodinium bahamense Plate, 1906 var. was collected Topolobampo–Santa Maria–Ohuira lagoon system California May 2005. Average concentrations P. were 100 cells liter−1. This finding is first observation vegetative this tropical species and represents its northernmost occurrence to date.
Resumen.-Se determinó la respuesta fisiológica del fitoplancton en zona
The lagoon is a component of coastal zones, whose populations autotrophic picoplankton (APP) remain largely unstudied. These lagoons display high-nutrient productivity and additionally may also be subjected to anthropogenic activities. This study selected Laguna Macapule, located on the eastern shore in mid-region Gulf California, due fact that drainage network servicing surrounding agricultural region (>230,000 hectares under cultivation) directs irrigation runoff, shrimp farm effluents,...
Nitrogen-fixation (FBN) rates were determined for the first time in euphotic zone (0-43 m) and at 150 m depth using high-sensitive 15 N 2 tracer method Alfonso Basin, Gulf of California, during May 2012.In this study, high (437 mol -2 d -1 integrated 0-150 estimated under conditions nutrient enrichment expansion hypoxic relative to other observations restricted systems Eastern North Pacific.These data support previous affirmations about significant FBN regulation pathway on nitrogen...
Seasonal changes in the spatial distribution of phytoplankton community were determined inBahía Concepción, B.C.S., from 1991 to 1993. The total abundance and seasonal variations size fractions (nanno microphytoplankton) as well its structure determined. A 235 taxa identified. Diatoms best represented group due their high species richness (131). most important genera Chaetoceros, Rhizosolenia Nitzschia. second dinoflagellates (92 species), mainly by Protoperidinium, Ceratium Prorocentrum....
