Mathematical algorithms relate satellite data of ocean color with the surface Chlorophyll-a concentration (Chl-a), a proxy of phytoplankton biomass. These mathematical tools work best when they are adapted to the unique bio-optical properties of a pa

The influence of easterly and northeasterly dry and warm Santa Ana winds (SAw) on the surface circulation of Todos Santos Bay, Mexico, is studied from surface currents and wind data measured during the most extreme periods of activity (autumn-winter

Based on the linearized shallow water equations with no rotation and no viscosity, in a rectangular channel with topography, the analytical solution for elevation and velocity was obtained. The bathymetry of the rectangular channel is described by a

Vertical distribution of chlorophyll a (Chla) in the euphotic zone has been described and modeled by a Gaussian curve representing those cases where there is a single Chla maximum (surface or subsurface). This has led to the rejection of profiles wit

Phytoplankton phenology and primary production were examined in the Iceland–Faroe region through synthesis of all available data, both in situ and remotely sensed. In the Arctic water, the early onset of stratification in spring gave rise to the ra

An inexpensive and easily implemented device to measure wind velocity is proposed. This prototype has the advantage of being able to measure both the speed and the direction of the wind in two dimensions. The device utilizes a computational interface
