    Description: Contrasting models predict two different climate change scenarios for the Southern Ocean (SO), forecasting either less or stronger vertical mixing of the water column. To investigate the responses of SO phytoplankton to these future conditions, we sampled a natural diatom dominated (63%) community from today's relatively moderately mixed Drake Passage waters with both low availabilities of iron (Fe) and light. The phytoplankton community was then incubated at these ambient open ocean conditions (low Fe and low light, moderate mixing treatment), representing a control treatment. In addition, the phytoplankton was grown under two future mixing scenarios based on current climate model predictions. Mixing was simulated by changes in light and Fe availabilities. The two future scenarios consisted of a low mixing scenario (low Fe and higher light, low mixing treatment) and a strong mixing scenario (high Fe and low light, strong mixing treatment). In addition, communities of each mixing scenario were exposed to ambient and low pH, the latter simulating ocean acidification (OA). The effects of the scenarios on particulate organic carbon (POC) production, trace metal to carbon ratios, photophysiology and the relative numerical contribution of diatoms and nanoflagellates were assessed. During the first growth phase, at ambient pH both future mixing scenarios promoted the numerical abundance of diatoms (~75%) relative to nanoflagellates. This positive effect, however, vanished in response to OA in the communities of both future mixing scenarios (~65%), with different effects for their productivity. At the end of the experiment, diatoms remained numerically the most abundant phytoplankton group across all treatments (~80%). In addition, POC production was increased in the two future mixing scenarios under OA. Overall, this study suggests a continued numerical dominance of diatoms as well as higher carbon fixation in response to both future mixing scenarios under OA, irrespective of different changes in light and Fe availability.

    Description: Two Fe-Mn bottle amendment experiments with two natural phytoplankton communities were performed during Polarstern expedition PS97 in 2016 in the Drake Passage. At two locations, sea water was pumped (using trace metals clean techniques) from 25m depth and used to fill polycarbonate bottles after having passed through a cleaned 200 μm mesh (removing large grazers). The Control treatment was the sampled seawater without any trace metals addition while the other three treatments were enriched with either FeCl3 alone (0.5 nM; +Fe treatment) or MnCl2 alone (1 nM; +Mn treatment) or both trace metals together (+FeMn treatment). All treatments were done in triplicate 2,5L PC bottles. All incubation bottles were maintained at 30 μmol photons m-2 s-1 under a 16:8 (light:dark) hour cycle at 1 ̊C. Autotrophic picoeukaryotes were analyzed via flow cytometry. At the start and the end of the experiments, samples were preserved with 10% buffered formalin, flash-frozen in liquid nitrogen, and analyzed flow cytometrically to assess picoplankton densities. Before running the samples, 2 μL beads (Sperotech - Rainbow Fluorescent Particles (RFPs) - 2.11 μm) were added to each treatment as a size and fluorescence reference. Then picoeukaryotes were identified based on side scatter versus FL-3. Three P subgroups (0.2 – 2 μm) were differentiated according to their size : small (P1), medium (P2) and large (P3), according to sub-cluster of events.

To determine the effects of the different treatments on the microplankton composition for the two Fe-Mn enrichment experiments, unfiltered seawater was collected at the start and the end of both experiments for later analysis via light microscopy in the home laboratory. Briefly, samples were fixed with hexamine-buffered formalin solution (2% final concentration) and Lugol's solution (1% final concentration) and stored at 2 °C in the dark until taxonomic analysis. All samples were allowed to settle in Utermöhl sedimentation chambers for at least 24 hours and were analyzed on an inverted light microscope, according to the method of Utermöhl (1958). Species were counted and identified according to taxonomic literature. Each aliquot was examined until at least 400 cells had been counted.

    Description: The data set was acquired during the PHYCOB cruise in the frame of the Eurofleets+ programme (https://www.eurofleets.eu/2021/10/22/phycob-an-international-oceanographic-expedition-into-the-western-black-sea-coordinated-by-the-alfred-wegner-institut-helmholtz-zentrum-fur-polar-und-meeresforschung-awi/) within the Regional call in the territorrial waters of Romania and Bulgaria in the Western Baltic Sea from 11th to 17th September 2021. The aim of the cruise was to assess the occurrence of potentially harmfal algae and their associated phycotoxins in the Black Sea and the accompanying environmental parameters. Sampling was performed by CTD casts and Rosette water sampling in addition to vertical phytoplankton net hauls from 30 m depth to surface. The determined parameters include the following: Quantitative phytoplankton cell counts in water samples, qulitative determination of toxigenic species next generation sequencing data in plankton net concentrates, monoclonanal cultures established from water sample isolates, phycotoxins in plankton net concentrates, inorganic nitruinets (nitrate/nitrite, phosphate, silicate) , vitamin B12, particulate organic carbon, particulate organic nitrogen, flowcytometry data, and CTD data (temperature, salinity, chlorophyll-a, oxygen, turbidity, radiance).

    Description: Samples for biological and chemical parameters were collected at the surface (3m), pyrocline, and the deep chlorophyll a maximum using the CTD (Conductivity, Temperature, and Depth) rosette outfitted with Niskin bottles. Nitrite and nitrate (NO3-+NO2-) referred to as Nox, ortho-phosphate as phosphorus (o-PO43-) and silica (SiO2) were analysed using a QuAAtro39 Continuous Segmented Flow Analyzer. Size fractionated chlorophyll a was collected by filtering water through 0.2 µm and 2 µm polycarbonate filters and frozen on board to be analysed later in the lab using standard fluorometric techniques. Duplicate particulate organic carbon and nitrogen (POC and PON) samples were collected on pre- combusted GF/F glass fiber filters, and stored frozen at -20°C until subsequent analysis on anelemental analyser in the lab. Whole water samples were preserved with 10% buffered formalin (1 % v/v final) and analyzed by flow cytometry to assess picoplankton densities. Abundance of heterotrophic bacteria (stained with SYBR Green I), phycoerythrin-containing picocyanobacteria, and photosynthetic picoeukaryotes were quantified using a Beckson Dickson Accuri C6 Flowcytometer using fluorescence patterns and particle size from side angle light scatter.

    Description: The dataset shows the orginal data based on which grazing rates of micro- and nanozooplankton and the growth rates of their prey, in austral autumn (April) close to the Antarctic Peninsula in the SO, were calculated in Böckmann et al. (2024). The data was measured by dilution experiments. Besides the, in such experiments classically investigated chlorophyll a, particulate organic carbon, particulate organic nitrogen, abundances of picoplankton and nanoplankton as well as bacterial abundances were measured at three stations in the Bransfield Strait, Drake Passage and Scotia Sea. Samples were taken during PS112 from a depth of 25 meters, using a polyethylene line connected to an ALMATEC membrane pump, by careful (laminar flow, 3-6 liters per minute, bubble free bottle filling) and trace metal clean techniques, successfully used since 2014. The data was collected to investigate the importance that nano- and microzooplankton grazers have for the carbon cycle in the Southern Ocean.
