High tolerance of microzooplankton to ocean acidification in an Arctic coastal plankton community
Impacts of ocean acidification (OA) on marine biota have been observed in a wide range of marine systems. We used a mesocosm approach to study the response of a high Arctic coastal microzooplankton community during the post-bloom period in Kongsfjorden (Svalbard) to direct and indirect effects of high pCO2/low pH. We found almost no direct effects of OA on microzooplankton composition and diver...
متن کاملEffects of ocean acidification on primary production in a coastal North Sea phytoplankton community
We studied the effect of ocean acidification (OA) on a coastal North Sea plankton community in a long-term mesocosm CO2-enrichment experiment (BIOACID II long-term mesocosm study). From March to July 2013, 10 mesocosms of 19 m length with a volume of 47.5 to 55.9 m3 were deployed in the Gullmar Fjord, Sweden. CO2 concentrations were enriched in five mesocosms to reach average CO2 partial pressu...
متن کاملNo observed effect of ocean acidification on nitrogen biogeochemistry in a summer Baltic Sea plankton community
Nitrogen fixation by filamentous cyanobacteria supplies significant amounts of new nitrogen (N) to the Baltic Sea. This balances N loss processes such as denitrification and anammox, and forms an important N source supporting primary and secondary production in N-limited postspring bloom plankton communities. Laboratory studies suggest that filamentous diazotrophic cyanobacteria growth and N2-f...
متن کاملOcean acidification reduces transfer of essential biomolecules in a natural plankton community
Ocean acidification (OA), a process of increasing seawater acidity caused by the uptake of anthropogenic carbon dioxide (CO2) by the ocean, is expected to change surface ocean pH to levels unprecedented for millions of years, affecting marine food web structures and trophic interactions. Using an in situ mesocosm approach we investigated effects of OA on community composition and trophic transf...
متن کاملEffect of ocean acidification on the fatty acid composition of a natural plankton community
The effect of ocean acidification on the fatty acid composition of a natural plankton community in the Arctic was studied in a large-scale mesocosm experiment, carried out in Kongsfjorden (Svalbard, Norway) at 79°N. Nine mesocosms of ∼50 m3 each were exposed to 8 different pCO2 levels (from natural background conditions to ∼1420 μatm), yielding pH values (on the total scale) from ∼8.3 to 7.5. I...
