Submarine groundwater discharge (SGD), the flow of fresh and saline groundwater from the seabed into the coastal ocean, has been intensively investigated in the recent years....

Within the BMBF funded project GENUS (Geochemistry and Ecology of the Namibian Upwelling System) the mole fraction of CO2 (xCO2) was measured in surface waters by using an...

Inversion of estuaries in the dry tropics (i.e. salinity increases upstream) in front of the backdrop of a globally changing climate forces migratory clupeid fish species to...

In 1982 and 1983, sheltered upper intertidal and supratidal habitats on Sylt island were quantitatively studied for meiofauna, with special emphasis on platyhelminths. This...

Denitrification on continental margins and in coastal sediments is a major sink of reactive N in the present nitrogen cycle and a major ecosystem service of eutrophied coastal...

Coccolithophores are unicellular pelagic algae, capable of calcification. In the Mediterranean Sea, several species have a well-known haplo-diploid life cycle, alternating the...

In order to log the temporal development of macrozoobenthos populations, three coastal areas of the North Sea and the Wadden Sea near Sylt were sampled at least once a year in...

Ocean warming and acidification may substantially affect the reproduction of keystone species such as Fucus vesiculosus (Phaeophyceae). In four consecutive benthic mesocosm...

In september 2010 bulk soil samples were taken from 82 plots in the Jena Experiment main experiment. Per plot 5 cores of 15 cm depth were taken, pooled and sieved. From the...

Data on kinematics of swimming behavior of Atlantic herring larvae cultured in the laboratory under three pCO2 conditions (control - 370, medium - 1800, and high - 4200 µatm)...

Marine copepods provide the major food-web link between primary producers and higher trophic levels, and their feeding ecology is of acute interest in light of global change...

Climate change and species introductions strongly changed macrobenthic community composition in the North Sea during past decades. To find out whether there was a similar change...

To study the response of the smaller benthic biota to larger food-falls and their possible effects on the biodiversity at the deep seafloor, we deployed the halves of a...

Background: Evolutionary shifts in bacterial virulence are often associated with a third biological player, for instance temperate phages, that can act as hyperparasites. By...

The transition from benthos to plankton requires multiple adaptations, yet so far it remains unclear how these are acquired in the course of the transition. To investigate this...

Species with wide dispersal are expected to have little empty habitat. This was tested by analysing habitat use in the Wadden Sea near the island of Sylt (North Sea). Sampling...

Habitat stratification by abiotic and biotic factors initiates divergence of populations and leads to ecological speciation. In contrast to fully marine waters, the Baltic Sea...

As the determinant of solute and particle fluxes through sediments, quantifying sediment permeability is vital step in understanding of the exchange phenomena between the water...

Using outdoor mesocosms we investigated the relative importance of the direct and indirect (here: altered grazing) effects of seawater warming on benthic microalgae in a Baltic...

Diurnal variation of net community production (NEP) and net community calcification (NEC) were measured in coral reef and seagrass biomes during October 2012 in the lower...
