Abstract: | In October 1992, the Oceanographic Centre of Málaga of the Spanish Oceanographical Institute (IEO) started a monitoring project,Ecomálaga, which collects physical, chemical, biological and sedimentological data from the Alborán Sea shelf. The project is coordinated
with similar projects in the Atlantic and Mediterranean Centres of IEO. The ultimate objective is to, understand the long-term
changes of the essential marine-environmental parameters.
So far, nine quarterly surveys have been carried out—from October 1992 to December 1994. The following variables were registered:abiotic: location weather, water temperature, salinity, pH, dissolved oxygen, chlorophyll a, nitrate, nitrite, phosphate, silicate,biotic: zooplankton biomass and species composition, and ichthyoplankton. The granulometric composition and organic matter content
of sediments are also included.
Data are stored in a computerized data base named Ecomálaga Data Base, with contributions from geology, physics, plankton
biology and marine chemistry. The data base not only contains separate files for each research topic, but also allows for
interchange between these files, resulting in a synoptic data output. It offers the users an output in the form of synthetic
records of each station sampled.
The analysis of the data indicates seasonal influences and ainshore-offshore gradient, as well as an Atlantic influence on
the stations located in the transect closest to the Strait of Gibraltar. |
