Abstract:
Seamounts are of great interest to science, industry and conservation because of their potential role as 'stirring rods' of the oceans, their enhanced productivity, their high local biodiversity, and the growing exploitation of their natural resources. This is accompanied by rising concern about the threats to seamount ecosystems, e.g. through over-fishing and the impact of trawling.
OASIS described the functioning characteristics of seamount ecosystems. OASIS' integrated hydrographic, biogeochemical and biological information. Based on two case studies. The scientific results, condensed in conceptual and mass balanced ecosystem models, were applied to outline a model management plan as well as site-specific management plans for the seamounts investigated.
OASIS addressed five main objectives:
Objective 1: To identify and describe the physical forcing mechanisms effecting seamount systems
Objective 2: To assess the origin, quality and dynamics of particulate organic material within the water column and surface sediment at seamounts.
Objective 3: To describe aspects of the biodiversity and the ecology of seamount biota, to assess their dynamics and the maintenance of their production.
Objective 4: Modelling the trophic ecology of seamount ecosystems.
Objective 5: Application of scientific knowledge to practical conservation.
