          Abstract

          La isla Malpelo conforma la ecorregión insular del Pacífico colombiano y contiene un mosaico de ecosistemas terrestres, litorales y submareales únicos. Considerando su carácter insular es de esperar que las características oceanográficas en esta localidad se encuentren influenciadas por la dinámica física y química del Pacífico Oriental Tropical (POT), siendo moduladas por las condiciones propias de la Cuenca Oceánica del Pacífico Colombiano (COPC). En este trabajo, se utilizó información in situ para describir las condiciones termohalinas de la columna de agua en la isla Malpelo e identificar las masas de agua dominantes durante los dos períodos hidroclimatológicos característicos de la COPC. Adicionalmente, se analizó la variabilidad térmica y halina en el COPC y se definió el campo de circulación geostrófico superficial a partir de información oceanográfica in situ durante los mismos períodos de tiempo con el propósito de evaluar su efecto sobre las condiciones oceanográficas en el ambiente pelágico de la isla Malpelo.

          Malpelo Island forms the insular ecoregion of the Colombian Pacific, and is composed by a mosaic of terrestrial ecosystems, and unique coastal and shallow subtidal systems. Considering its insular nature, the oceanographic features of this locality are expected to be related with the physical and chemical dynamics of the Eastern Tropical Pacific (ETP) and be modulated by the regional dynamic of the Colombian Pacific Oceanic Basin (COPC in Spanish). In this work, in situ data was used to describe the thermohaline conditions in the water column in Malpelo Island and identify key water mass during the two contrasting hydro-meteorological periods of the COPC. Furthermore, we analyzed the thermal and haline variability in the COPC and defined the surface geostrophic flow from in situ oceanographic data during the same time in order to evaluate its effect on the oceanographic conditions in the pelagic environment off Malpelo Island.

            New paradigms for supporting the resilience of marine ecosystems.

            Resource managers and scientists from disparate disciplines are rising to the challenge of understanding and moderating human impacts on marine ecosystems. Traditional barriers to communication between marine ecologists, fisheries biologists, social scientists and economists are beginning to break down, and the distinction between applied and basic research is fading. These ongoing trends arise, in part, from an increasing awareness of the profound influence of people on the functioning of all marine ecosystems, an increased focus on spatial and temporal scale, and a renewed assessment of the role of biodiversity in the sustainability of ecosystem goods and services upon which human societies depend. Here, we highlight the emergence of a complex systems approach for sustaining and repairing marine ecosystems, linking ecological resilience to governance structures, economics and society.
