    In:  Supplement to: Lebrato, Mario; Mendes, Pedro André; Steinberg, Deborah K; Birsa, Laura M; Benavides, Mar; Oschlies, Andreas (2013): Jelly biomass sinking speed reveals a fast carbon export mechanism. Limnology and Oceanography, 58(3), 1113-1122, https://doi.org/10.4319/lo.2013.58.3.1113

    Description: Sinking of gelatinous zooplankton biomass is an important component of the biological pump removing carbon from the upper ocean. The export efficiency, e.g., how much biomass reaches the ocean interior sequestering carbon, is poorly known because of the absence of reliable sinking speed data. We measured sinking rates of gelatinous particulate organic matter (jelly-POM) from different species of scyphozoans, ctenophores, thaliaceans, and pteropods, both in the field and in the laboratory in vertical columns filled with seawater using high-quality video. Using these data, we determined taxon-specific jelly-POM export efficiencies using equations that integrate biomass decay rate, seawater temperature, and sinking speed. Two depth scenarios in several environments were considered, with jelly-POM sinking from 200 and 600 m in temperate, tropical, and polar regions. Jelly-POM sank on average between 850 and 1500 m/d (salps: 800-1200 m/d; ctenophores: 1200-1500 m/d; scyphozoans: 1000-1100 m d; pyrosomes: 1300 m/d). High latitudes represent a fast-sinking and low-remineralization corridor, regardless of species. In tropical and temperate regions, significant decomposition takes place above 1500 m unless jelly-POM sinks below the permanent thermocline. Sinking jelly-POM sequesters carbon to the deep ocean faster than anticipated, and should be incorporated into biogeochemical and modeling studies to provide more realistic quantification of export via the biological carbon pump worldwide.

    In:  Supplement to: Neuer, Susanne; Davenport, Robert; Freudenthal, Tim; Wefer, Gerold; Llinás, Octavio; Rueda, Mariá-José; Steinberg, Deborah K; Karl, David Michael (2002): Differences in the biological carbon pump at three subtropical ocean sites. Geophysical Research Letters, 29(18), 1885, https://doi.org/10.1029/2002GL015393
    Publication Date: 2024-02-17
    Description: We report primary production of organic matter and organic carbon removal from three subtropical open ocean time-series stations, two located in the Atlantic and one in the Pacific, to quantify the biological components of the oceanic carbon pump. We find that within subtropical gyres, export production varies considerably despite similar phytoplankton biomass and productivity. We provide evidence that the removal of organic carbon is linked to differences in nutrient input into the mixed layer, both from eddy induced mixing and dinitrogen fixation. These findings contribute to our knowledge of the spatial heterogeneity of the subtropical oceans, which make up more than 50% of all ocean area and are thought to spread in the course of CO2- induced global warming.

    Description: Although the oceanic widespread pelagic tunicate Soestia zonaria has been studied for more than a century, little ecological information exists. Soestia primarily occurs in tropical to warm-temperate regions. Soestia specimens were collected in 2008 and 2021 during two research expeditions (EXPORTS cruise to the Northeast Atlantic and TAN0806 over the Chatham Rise, New Zealand) using MOCNESS-1 net and large midwater trawl with maximum sampling depths of 1000 m. In total, 140 Soestia specimens (oral-atrial length: 7–54 mm) were analysed for biomass parameters (wet weight, dry weight, ash-free dry weight, water content, organic content) and stoichiometry (carbon and nitrogen content, carbon-to-nitrogen ratio).
