Three decades of sea water abstraction by Kapar power plant (Malaysia): What impacts on tropical zooplankton community?

Zooplankton samples collected before (1985–86) and after (2013–14) the establishment of Kapar power station (KPS) were examined to test the hypothesis that increased sea surface temperature (SST) and other water quality changes have altered the zooplankton community structure. 151 more words


Shifts in the microbial community in the Baltic Sea with increasing CO2

Ocean acidification, due to dissolution of anthropogenically produced carbon dioxide is considered a major threat to marine ecosystems. The Baltic Sea, with extremely low salinity and thus low pH buffering capacity, is likely to experience stronger variation in pH than the open ocean with increasing atmospheric carbon dioxide. 229 more words


Effect of ocean acidification on the structure and fatty acid composition of a natural plankton community in the Baltic Sea

Increasing atmospheric carbon dioxide (CO2) is changing seawater chemistry towards reduced pH, which consequently affects various properties of marine organisms. Coastal and brackish water communities are expected to be less affected by ocean acidification (OA) as these communities are typically adapted to high fluctuations in CO2 and pH. 217 more words


Basking Shark Facts

The Basking shark (Cetorhinus maximus) is the Britain’s largest fish and the world’s second largest fish, after the Whale Shark (Rhincodon typus), and like the whale shark, it too feeds on some of the smallest creatures in the ocean; plankton. 395 more words


Direct and indirect impact of near-future pCO2 levels on zooplankton dynamics

Ocean acidification has direct physiological effects on organisms by, for example, dissolving the calcium carbonate structures of calcifying species. However, non-calcifiers may also be affected by changes in seawater chemistry. 202 more words


Carbon-13 labelling shows no effect of ocean acidification on carbon transfer in Mediterranean plankton communities

Despite an increasing number of experiments, no consensus has emerged on the effect of ocean acidification on plankton communities and carbon flow. During two experiments, performed in the Bay of Calvi (France, Corsica; summer 2012) and the Bay of Villefranche (France; winter 2013), nine off-shore mesocosms (∼50 m3) were deployed among which three served as controls and six were enriched with CO2 to reach partial pressure of CO2 (pCO2) levels from 450 to 1350 μatm and 350 to 1250 μatm in the Bay of Calvi and the Bay of Villefranche, respectively. 191 more words


Ocean acidification does not alter grazing in the calanoid copepods Calanus finmarchicus and Calanus glacialis

It is currently under debate whether organisms that regulate their acid–base status under environmental hypercapnia demand additional energy. This could impair animal fitness, but might be compensated for via increased ingestion rates when food is available. 182 more words
