Abstract
El registro sedimentario reciente en la bahía de Pasaia ha sido estudiado
mediante 3 sondeos submareales. Los testigos muestran un sedimento de grano
fino, unos valores muy elevados de contaminantes metálicos y una presencia
muy escasa de microfauna, sugiriendo malas condiciones ambientales que han
sido persistentes durante al menos las últimas 6 décadas. Estas circunstancias
son decisivas para desarrollar una adecuada gestión de este medio estuarino
The recent sedimentary record of the Pasaia bay has been analysed using 3 subtidal cores. These contain fine-grained sediments, very high metallic pollutants and very scarce microfauna. They are indicative of negative environmental conditions that have been persistent in this area at least during the last 6 decades. These characteristics are decisive in order to perform an adequate management of this estuarine setting
