    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: Data presented here were collected during the cruise UT2020-01 (Project HAB DK/Limfjord, 'Harmful Algae Blooms in Danisch waters') with the RV Uthörn from Bremerhaven to Bremerhaven (13.08. - 21.08. 2020 and 21.09. - 27.09.2020) , with station work in the German Bight and the Limfjord. In total, 34 vertical CTD-hauls were conducted. The CTD system used was a Sea-Bird Electronics Inc. SBE 19plus, attached to a SBE 55 Carousel Water Sampler containing 6 x 4-liter bottles. The system was equipped with: single temperature and conductivity probe (SBE 7245), a pressure sensor (Digiquartz), a fluoroscence sensor (Turner Scufa) and an oyxgen probe (Aanderaa optode, SN 1542). The sensors were pre-calibrated by the manufacturers. The data were recorded with the Seasave (V 7.26.7.107) software and processed using SeaBird SBE Data Processing software (V 7.26.7.1, DataConversion, Filter, LoopEdit, Bin Average) and visually checked. The ship position was derived from the shipboard GPS-system. The time zone is given in UTC.

    Description: 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 light level.

    Description: Harmful Algae Blooms pose an increasing threat to the public health and economic stability of Southern Chile, particularly to the aquaculture industries. This fieldwork performed during the PROFAN expedition from 12th to 22nd November 2019 extends the knowledge on the distribution of marine toxin-producing species in the difficult to access Última Esperanza Province in the Magallanes Region. Paralytic Shellfish Poisoning toxins with high relative abundances of saxitoxin and lipophilic toxins dominated by yessotoxins, pectenotoxins and domoic acid were detected at nearly each sampling station. The respective toxin-producing organisms are mainly from the genus Alexandrium and Dinophysis. Furthermore, the first detection of pinnatoxin-G (PnTx-G) in Chilean waters strongly indicates the presence of the dinoflagellate Vulcanodinium rugosum.
