Canary Islands Azores Gibraltar Observation

Exploitable results

Summary: Seasonal particle flux was investigated along a productivity gradient reaching from the NW African upwelling margin to the oligotrophic gyre region. Particle flux maxima along the gradient were related to the winter bloom at all stations and were higher close to shore. Deep particle advection plays an important role in determining magnitude and timing of particle flux along the entire transect as shown by increasing particle fluxes with depth. Spatial and temporal variability of environmental processes in the Canary Islands region was investigated on surface sediments and sediment cores. The Holecene spatial variability of climate-sensitive parameters (e.g TOC, carbonate, benthic and planktic foraminifera, nitrogen isotopes) in surface sediments mirror the high biomass gradient from the coast to the open ocean. In time-series from sediment cores accumulation rates of climate-sensitive parameters also reflect the productivity gradient. Upwelling and filament production was stronger during glacial times.
