Frequency of algae along a transect at the island of Helgoland in 2005
A sublittoral transect (P3) in the North of Helgoland that had been investigated ~40 years earlier by Lüning (1970) was traversed again. Scuba dives were carried out between... -

Experiment: Combined effects of CO2, temperature, irradiance and time on the ...
In natural environments, marine biotas are exposed to a variety of simultaneously acting abiotic factors. Among these, temperature, irradiance and CO2 availability are major... -
Experiment: Competition between calcifying and noncalcifying temperate marine...
Since pre-industrial times, uptake of anthropogenic CO2 by surface ocean waters has caused a documented change of 0.1 pH units. Calcifying organisms are sensitive to elevated... -
