Increased CO2 modifies the carbon balance and the photosynthetic yield of two...
Ocean acidification affects with special intensity Arctic ecosystems, being marine photosynthetic organisms a primary target, although the consequences of this process in the... -
Effect of acidification on an Arctic phytoplankton community from Disko Bay, ...
Long-term measurements (i.e. months) of in situ pH have not previously been reported from the Arctic; this study shows fluctuations between pH 7.5 and 8.3 during the spring... -
Mesozooplankton community development at elevated CO2
The increasing CO2 concentration in the atmosphere caused by burning fossil fuels leads to increasing pCO2 and decreasing pH in the world ocean. These changes may have severe... -
Gene expression profiling in gills of the great spider crab Hyas araneus in r...
In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Lavigne et al, 2014) was used to compute a complete and consistent set of... -
Sensitivity to ocean acidification parallels natural pCO2 gradients experienc...
The Arctic Ocean is a bellwether for ocean acidification, yet few direct Arctic studies have been carried out and limited observations exist, especially in winter. We present... -
Impacts of ocean acidification on sediment processes in shallow waters of the...
Despite the important roles of shallow-water sediments in global biogeochemical cycling, the effects of ocean acidification on sedimentary processes have received relatively... -
Performance of the Arctic calanoid copepods Calanus glacialis and C. hyperbor...
The sensitivity of copepods to ocean acidification (OA) and warming may increase with time, however, studies >10 days and on synergistic effects are rare. We therefore... -
CO2-induced fertilization impairment in Strongylocentrotus droebachiensis col...
Fertilization depends on distribution and aggregation patterns of sea urchins which influence gamete contact time and may potentially enhance their vulnerability to ocean... -
Effects of pre-hatching pCO2 on development and survival of zoea stages of Ar...
Sensitivity of marine crustaceans to anthropogenic CO2 emissions and the associated acidification of the oceans may be less than that of other, especially lower, invertebrates.... -
Effects of ocean acidification on respiration, growth and C:N ratio of arctic...
Early life stages of marine crustaceans respond sensitively to elevated seawater PCO2. However, the underlying physiological mechanisms have not been studied well. We therefore... -
Seawater carbonate chemistry, survival rate, shell size, calcification rate o...
The present study investigated the effects of ocean acidification and temperature increase on Neogloboquadrina pachyderma (sinistral), the dominant planktonic foraminifer in the... -
Effects of ocean acidification on overwintering juvenile Arctic pteropods Lim...
Pteropods are planktonic mollusks that play an important role in the food web of various ecosystems, particularly at high latitudes. Because they produce an aragonitic shell,... -
The synergistic effects of increasing temperature and CO2 levels on activity ...
In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Lavigne and Gattuso, 2011) was used to compute a complete and consistent... -
EPOCA Svalbard 2009 benthic experiment: Serripes study, 2009
Ocean acidification influences sediment/water nitrogen fluxes, possibly by impacting on the microbial process of ammonia oxidation. To investigate this further, undisturbed... -
Surface seawater carbonate chemistry, nutrients and phytoplankton community c...
This data was collected during the 'ICE CHASER' cruise from the southern North Sea to the Arctic (Svalbard) in July-Aug 2008. This data consists of coccolithophore abundance,... -
Seawater carbonate chemistry and biological processes of Limacina helicina du...
Due to their aragonitic shell, thecosome pteropods may be particularly vulnerable to ocean acidification driven by anthropogenic CO2 emissions. This applies specifically to... -
Seawater carbonate chemistry and biological processes during experiments with...
The Arctic Ocean and its associated ecosystems face numerous challenges over the coming century. Increasing atmospheric CO2 is causing increasing warming and ice melting as well... -
Seawater carbonate chemistry, shell linear extension and calcification during...
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... -
Replication Data for: Phthalate contamination in marine mammals off the Norwe...
Phthalates are used in plastics, found throughout the marine environment and have the potential to cause adverse health effects. In the present study, we quantified blubber... -
UHH Sea Ice Area Product
Abstract: This data set comprises time series of the monthly sea-ice area (SIA) in the Northern Hemisphere (1 file) and in the Southern Hemisphere (1 file). SIA is derived from...
