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... -
Seawater carbonate chemistry and the net calcification and photosynthesis rat...
In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2016) was used to compute a complete and consistent set of... -
Seawater carbonate chemistry and primary production, respiration, calcificati...
Rising levels of anthropogenic carbon dioxide (CO2) in the atmosphere over the past several decades has resulted in a changing climate and is projected to further fuel global... -
Experiment: Elevated CO2 levels affect the activity of nitrate reductase and ...
The concentration of CO2 in global surface ocean waters is increasing due to rising atmospheric CO2 emissions, resulting in lower pH and a lower saturation state of carbonate... -
Experiment: Physiological responses of the calcifying rhodophyte, Corallina o...
Future atmospheric CO2 levels will most likely have complex consequences for marine organisms, particulary photosynthetic calcifying organisms. Corallina officinalis L. is an... -
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... -
Seawater carbonate chemistry, gross photosynthesis and metabolically induced ...
Ocean acidification (OA) is a reduction in oceanic pH due to increased absorption of anthropogenically produced CO2. This change alters the seawater concentrations of inorganic... -
