Las tendencias de los últimos 20 años indican a nivel mundial un aumento de la contaminación marina, una aceleración de la destrucción de los hábitats marino-costeros y, en muchas áreas una menor captura de especies marinas afectadas por la pesca excesiva y la contaminación. Se estudiaron (1995-1996) los patrones de transporte de nutrientes, la estacionalidad del oxígeno y de los nutrientes disueltos; la escorrentía de los principales ríos, su aporte de nutrientes y su contribución sobre los niveles de clorofila-a (como aproximación a biomasa de fitoplankton); distribución de metales pesados en los sedimentos y el contenido de metales de la biota como posibles bioindicadores; el modelaje hidrodinámico de los procesos de transporte y circulación de las aguas en el Golfo de Nicoya, así como el modelaje parcial de la dinámica de los nutrientes.
The trends of the last 20 years indicate a worldwide increase in marine pollution, an acceleration of the destruction of marine-coastal habitats and, in many areas, a lower capture of marine species affected by excessive fishing and pollution. The patterns of nutrient transport, the seasonality of oxygen and dissolved nutrients were studied (1995-1996); the runoff from the main rivers, their contribution of nutrients and their contribution to the levels of chlorophyll-a (as an approximation to phytoplankton biomass); heavy metal distribution in sediments and biota metal content as potential bioindicators; the hydrodynamic modeling of the transport and circulation processes of water in the Gulf of Nicoya, as well as the partial modeling of the nutrient dynamics.
