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...
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...
Imminent ocean acidification in the Arctic projected with the NCAR global coupled carbon cycle-climate model
ocean acidification Arctic NCAR global coupled carbon cycle-climate model
2010/1/19
Ocean acidification from the uptake of anthropogenic carbon is simulated for the industrial period and IPCC SRES emission scenarios A2 and B1 with a global coupled carbon cycle-climate model. Earlier ...
Evidence for a multi-species coccolith volume change over the past two centuries:understanding a potential ocean acidification response
multi-species coccolith volume change potential ocean acidification response
2010/1/18
Major questions surround the species-specific nature of coccolithophore calcification in response to rising atmospheric CO2 levels. Here we present CaCO3 particle volume distribution data from the coc...
