Effects of seawater pCO2 and temperature on shell growth, shell stability,...

Acidification of the World’s oceans may directly impact reproduction, performance and shell formation of marine calcifying organisms. In addition, since shell production is costly and stress in general...

Modelling the dissolved inorganic carbon system in the Baltic Sea

Oceans are capable of storing part of the emitted anthropogenic carbon dioxide (CO2) due to the formation of carbonic acid and subsequent dissociation. CO2 is also assimilated by biota and the...

Projected marine climate change: effects on copepod oxidative status and...

Zooplankton are an important link between primary producers and fish. Therefore, it is crucial to address their responses when predicting effects of climate change on pelagic ecosystems. For realistic...

Impact of CO2 enrichment on organic matter dynamics during nutrient induced...

A mesocosm experiment was conducted to investigate the impact of rising fCO2 on the build-up and decline of organic matter during coastal phytoplankton blooms. Five mesocosms (∼38 m³ each) were...

Effect on pCO2 by phytoplankton uptake of dissolved organic nutrients in the...

Dissolved organic matter (DOM) has been added to an existing biogeochemical model and the phytoplankton were allowed to utilize the dissolved organic nutrients for primary production. The results show...
