15N nitrate uptake assays were conducted using tracer additions of highly enriched (98%) 15N-labeled nitrate for four Arctic-adapted strains of Thalassiosira gravida and three...

This dataset presents the results of temperature performance curve (TPC) experiments conducted on Arctic and temperate diatom species to investigate their thermal adaptation....

This dataset encompasses maximum growth rates derived from photoperiod reaction norm experiments conducted on Arctic and temperate strains of the diatoms Thalassiosira gravida...

The dataset includes recordings from laser strainmeters, a weather station and several groundwater monitoring wells from Moxa Geodynamic Observatory, located in central Germany....

Here, we investigatethe impacts of moderate (~700 μmol/kg) and high (~2700 μmol/kg) limestone-inspired alkalinity additionson two biogeochemically and ecologically important...

On board microscopic analyses of live net tow (vertical net tows of the upper water column from 30 m depth with a 20 µm mesh-size phytoplankton net) and rosette water samples...

We studied responses to simulated ocean acidification in three strains of the mixotrophic chrysophyte Ochromonas (CCMP1391, CCMP2951, and CCMP1393). After acclimatization of the...

This experiment aimed to understand a the high plasticity of Arctic diatoms towards ocean warming, with a special regard to regulatory mechanisms of photosynthetic and...

This study was conducted in autumn/winter 2021/2022 at the laboratory of the Alfred-Wegener-Institute Bremerhaven. To assess temperature response patterns of various functional...

We tested the antagonistic effects of three strains of the dinoflagellate HAB species Alexandrium catenella on three target species (the chlorophyte Tetraselmis sp., the...

We conducted a full-factorial lab experiment to study the individual and combined effects of temperature (18°C and 21°C), pCO2 (400 and 1000 ppm), and dissolved N:P ratio (16...

We assessed the responses of solitary cells of Arctic Isochrysis sp. grown under a matrix of temperature (2°C vs. 6°C), light intensity (55 vs. 160 μmol photons m-2 s-1) and CO2...

Although coccolithophore physiological responses to CO2-induced changes in seawater carbonate chemistry have been widely studied in the past, there is limited knowledge on the...

Phaeodactylum tricornutum strain CCAP 1052/1A was cultivated at 6°C and 15°C under controlled conditions (32 salinity, F/2 medium, 400 µatm pCO2, 100 µmol photons m-2 s-2 light...

Ocean acidification (OA) has important effects on the intrinsic phenotypic characteristics of many marine organisms. Concomitantly, OA can alter the extended phenotypes of these...

Many microbial photoautotrophs depend on heterotrophic bacteria for accomplishing essential functions. Environmental changes, however, could alter or eliminate such...

Coccolithophorid algae are microscopic but prolific calcifiers in modern and ancient oceans. When the pH of seawater is modified, as may occur in the future due to ocean...

We conducted a full-factorial lab experiment to study the individual and combined effects of temperature (18°C and 21°C), pCO2 (400 and 1000 ppm), and dissolved N:P ratio (16...

Increased carbon dioxide levels (CO2) in the atmosphere triggered a cascade of physical and chemical changes in the ocean surface. Marine organisms producing carbonate shells...

This paper present the effects of ocean acidification on growth and domoic acid (DA) content of several strains of the toxic Pseudo-nitzschia australis and the non-toxic P....
