MEDUSA-2.0: an intermediate complexity biogeochemical model of the marine carbon cycle for climate change and ocean acidification studies
MEDUSA-2.0 intermediate complexity biogeochemical model marine carbon cycle climate change ocean acidification studies
2014/12/12
MEDUSA-1.0 (Model of Ecosystem Dynamics, nutrient Utilisation, Sequestration and Acidification) was developed as an "intermediate complexity" plankton ecosystem model to study the biogeochemical respo...
Near-future levels of ocean acidification do not affect sperm motility and fertilization kinetics in the oyster Crassostrea gigas
Near-future levels ocean acidification sperm motility and fertilization kinetics the oyster Crassostrea gigas
2010/1/21
An increasing number of studies are now reporting the effects of ocean acidification on a broad range of marine species, processes and systems. Many of these are investigating the sensitive early life...
Rate of Iceland Sea acidification from time series measurements
Rate Iceland Sea acidification time series measurements
2010/1/21
The Iceland Sea is one part of the Nordic Seas. Cold Arctic Water prevails there and the deep-water is an important source of North Atlantic Deep Water. We have evaluated time series observations of m...
From laboratory manipulations to Earth system models:scaling calcification impacts of ocean acidification
laboratory manipulations Earth system models calcification impacts ocean acidification
2010/1/21
The observed variation in the calcification responses of coccolithophores to changes in carbonate chemistry paints a highly incoherent picture, particularly for the most commonly cultured "species", E...
The Arctic Ocean marine carbon cycle:evaluation of air-sea CO2 exchanges,ocean acidification impacts and potential feedbacks
Arctic Ocean marine carbon cycle evaluation air-sea CO2 exchanges ocean acidification impacts
2010/1/21
At present, although seasonal sea-ice cover mitigates atmosphere-ocean gas exchange, the Arctic Ocean takes up carbon dioxide (CO2) on the order of ?66 to ?199 Tg C year?1 (1012 g C), contributing 5–1...
Impact of anthropogenic ocean acidification on thermal tolerance of the spider crab Hyas araneus
anthropogenic ocean acidification thermal tolerance spider crab Hyas araneus
2010/1/21
Future scenarios for the oceans project combined developments of CO2 accumulation and global warming and their impact on marine ecosystems. The synergistic impact of both factors was addressed by stud...
Technical Note:Approaches and software tools to investigate the impact of ocean acidification
Approaches software tools impact ocean acidification
2010/1/21
Although future changes in the seawater carbonate chemistry are well constrained, their impact on marine organisms and ecosystems remains poorly known. The biological response to ocean acidification i...
The influence of hypercapnia and the infaunal brittlestar Amphiura filiformis on sediment nutrient flux – will ocean acidification affect nutrient exchange?
hypercapnia brittlestar Amphiura filiformis sediment nutrient flux ocean acidification
2010/1/21
Rising levels of atmospheric carbon dioxide and the concomitant increased uptake of this by the oceans is resulting in hypercapnia-related reduction of ocean pH. Research focussed on the direct effect...
Planktic foraminiferal shell thinning in the Arabian Sea due to anthropogenic ocean acidification?
Planktic foraminiferal shell thinning Arabian Sea anthropogenic ocean acidification
2010/1/21
About one third of the anthropogenic carbon dioxide (CO2) released into the atmosphere in the past two centuries has been taken up by the ocean. As CO2 invades the surface ocean, carbonate ion concent...

Impact ocean acidification key Arctic pelagic mollusc
2010/1/21
Thecosome pteropods (shelled pelagic molluscs) can play an important role in the food web of various ecosystems and play a key role in the cycling of carbon and carbonate. Since they harbor an aragoni...
Net Loss of CaCO3 from a subtropical calcifying community due to seawater acidification:mesocosm-scale experimental evidence

CO2-related acidification larval development European lobster
2010/1/20
Oceanic uptake of anthropogenic CO2 results in a reduction in pH termed "Ocean Acidification" (OA). Comparatively little attention has been given to the effect of OA on the early life history stages o...
