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...

We assessed the responses of solitary cells of Arctic Isochrysis sp. (Strain PS78) grown under a matrix of temperature (2°C vs. 6°C), light intensity (55 vs. 160 μmol photons...

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...

This study highlights the importance of manganese (Mn) next to iron (Fe) for the growth of specific Southern Ocean phytoplankton groups with important implications for primary...

We conducted a multiple-stressor experiment to evaluate the response of the still poorly studied key Antarctic cryptophyte species Geminigera cryophila (CCMP 2564, isolated from...

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...

Nodularia spumigena is a toxic, filamentous cyanobacterium capable to fix atmospheric nitrogen, which is often dominating cyanobacterial bloom events in the Baltic Sea and other...

Ecophysiological studies on Antarctic cryptophytes to assess whether climatic changes such as ocean acidification and enhanced stratification affect their growth in Antarctic...

The Arctic is one area that has been affected by rising temperatures, leading to an increase in meltwater in the water column. During the months of June/July 2019, fronds of the...

Temperature, salinity, oxygen, pH, and light intensity were measured daily, while nutrients (NO₂⁻, NO₃⁻, NH₄⁺, PO₄³⁻, Mg, Ca) were tested twice weekly. Xenia umbellata...

The genus Ulva, described as a good source of antioxidants known for its antibacterial properties and associated with the capacity to adapt to different environments and high...

Kelps (Phaeophyceae, Laminariales) function as ecosystem engineers along many Arctic rocky shores. With ongoing climate change, the frequency and intensity of marine heatwaves...

This dataset presents the number of germinated individuals that originated from protoplasts from Ulva lacinulata and Ulva compressa. The individuals are separated into different...

This dataset presents the diameter of the larger green cells found in the thalli of Ulva lacinulata and Ulva compressa that became protoplasts after being released to the water.

This dataset presents the fresh weight of U. lacinulata's biomass during the degradation experiment. This allowed the calculation of relative growth rates (RGR).

This dataset presents the number of protoplasts collected during the degradation experiment with Ulva lacinulata and Ulva compressa. This allowed the calculation of protoplast...

This dataset presents the diameter of the discs grown from protoplasts of Ulva lacinulata at the end of the germination experiment.

In the exponential growth phase, electron transport rates irradiance curves were conducted applying 10 irradiances from 0 up to ~1900 μmol photons m-2 s-1 for 5 min for each...

The effect of different light intensities (20, 100 and 200 μmol photons m-2 s-1) on the growth response, toxin/pigment/nutrient content and photophysiology of Alexandrium...
