Net hauls have so far provided valuable insights into the gelatinous zooplankton communities along our transect from the Mediterranean Sea into the North Atlantic Ocean. While our sampling sites in the Strait of Gibraltar were mostly populated by pelagic tunicates (salps), several hydromedusae (A. Liriope sp. with abundances of up to 1 ind. m-3), the […]

Catamaran trawl, collecting particles and microplastics from the sea surface in the strait of Gibraltar, between the Mediterranean Sea and Atlantic Ocean

We completed our first two stations without a problem. The Alkor crew knows our gear well, and deployment and retrieval are as smooth as the glassy sea surface right now. We’re collecting water and particles from the CTD/Niskin rosette, underway seawater system, and pumps that filter in situ. We use Bongo nets to collect particles […]

The main objective of our study is to unravel how changes in upwelling intensity affect the food web and elemental cycling in the Peruvian upwelling system. Simply speaking, should upwelling intensity decline let’s say by 50% […]
