    Physical oceanography during UTHÖRN cruise UT2020-01 (HAB-DK/Limfjord) (2023)
    PANGAEA
    Details
    Publication Date: 2024-01-31
    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.

    Defining planktonic protist functional groups on mechanisms for energy and nutrient acquisition : incorporation of diverse mixotrophic strategies (2016)

    Description: Arranging organisms into functional groups aids ecological research by grouping organisms (irrespective of phylogenetic origin) that interact with environmental factors in similar ways. Planktonic protists traditionally have been split between photoautotrophic “phytoplankton” and phagotrophic “microzooplankton”. However, there is a growing recognition of the importance of mixotrophy in euphotic aquatic systems, where many protists often combine photoautotrophic and phagotrophic modes of nutrition. Such organisms do not align with the traditional dichotomy of phytoplankton and microzooplankton. To reflect this understanding, we propose a new functional grouping of planktonic protists in an eco-physiological context: (i) phagoheterotrophs lacking phototrophic capacity, (ii) photoautotrophs lacking phagotrophic capacity, (iii) constitutive mixotrophs (CMs) as phagotrophs with an inherent capacity for phototrophy, and (iv) non-constitutive mixotrophs (NCMs) that acquire their phototrophic capacity by ingesting specific (SNCM) or general non-specific (GNCM) prey. For the first time, we incorporate these functional groups within a foodweb structure and show, using model outputs, that there is scope for significant changes in trophic dynamics depending on the protist functional type description. Accordingly, to better reflect the role of mixotrophy, we recommend that as important tools for explanatory and predictive research, aquatic food-web and biogeochemical models need to redefine the protist groups within their frameworks.
