The use of satellite images for the observation and measurement of marine turbidity has been developed mainly with ocean colour sensors, such as MODIS. These images have a maximum spatial resolution of 250 m in their visible and infrared bands. In th

We estimated phytoplankton primary productivity (PP) in the euphotic zone of the California Current System using chlorophyll concentration (Chl) from CZCS imagery. The area was divided into two regions, Southern California (SC) and Baja California (B

The Mexican Tropical Pacific has oligotrophic characteristics; however, it sustains an abundant biodiversity, mainly because of upwelling promoted by its relatively shallow thermocline, strong winds and mesoscale eddies. These features, together with

The construction of major dams in the Colorado River has produced a drastic effect on the amount of fresh water entering the Colorado River Delta. After 1935 there was a dramatic decrease in fresh-water input, causing ecological impacts and a decreas

In order to estimate primary productivity of the phytoplankton using the dissolved oxygen (ΔO2) method with different incubation times and to compare it with that estimated using the carbon fourteen (14C) method, simultaneous primary productivity ex

Most coastal lagoons that present high tide intervals and high turbulent kinetic energy have high turbidity and, therefore, light is a limiting factor for primary productivity. The Colorado River Delta has been reported with high turbidity values. Ou

In order to observe the effect of turbulent kinetic energy (TKE) on the spatial distribution of chlorophyll a, four spatial variations were analysed (two during high and two during low tide) on 15 and 16 April, 1989 in Puerto Don Juan. Observations w

In order to study the photosynthetic quotient variability (PQ = O2/14CO2) and to infer the relative contribution of new production in the Gulf of California, simultaneous determinations of photosynthesis were made using the 14C and oxygen techniques.

Tintinnids from Todos Santos Bay, Baja California (Mexico), were collected from 1980 to 1985 by means of 83 horizontal surface tows with a standard No. 20 net (75 µm mesh size). Based on lorica morphology, 66 species and 30 genera were identified. T
