    In:  Supplement to: Geibert, Walter; Assmy, Philipp; Bakker, Dorothee C E; Hanfland, Claudia; Hoppema, Mario; Pichevin, Laetitia; Schröder, Michael; Schwarz, Jill Nicola; Stimac, Ingrid; Usbeck, Regina; Webb, Adrian (2010): High productivity in an ice melting hot spot at the eastern boundary of the Weddell Gyre.

    Publication Date: 2023-10-28
    Description: The Southern Ocean (SO) plays a key role in modulating atmospheric CO2 via physical and biological processes. However, over much of the SO, biological activity is iron-limited. New in situ data from the Antarctic zone south of Africa in a region centered at -20°E - 25°E reveal a previously overlooked region of high primary production, comparable in size to the northwest African upwelling region. Here, sea ice together with enclosed icebergs is channeled by prevailing winds to the eastern boundary of the Weddell Gyre, where a sharp transition to warmer waters causes melting. This cumulative melting provides a steady source of iron, fuelling an intense phytoplankton bloom that is not fully captured by monthly satellite production estimates. These findings imply that future changes in sea-ice cover and dynamics could have a significant effect on carbon sequestration in the SO.

    Description: This dataset includes phytoplankton and simplistic protozooplankton analysis on seawater samples from the Chagos Archipelago, tropical Indian Ocean, May 2018. Cells were identified using light microscopy at x400 magnification. Cell dimensions were measured from photographs and biovolume was calculated following Sun & Liu (2003). A full description, including a guide to the data files, is given in file ReadMe.docx. Acknowledgement: Water samples were collected by Guy Stevens and Niv Froman from The Manta Trust, and by Tom Letessier from the Zoological Society of London, with funding from the Bertarelli Foundation as part of the Bertarelli Programme in Marine Science.

    Description: Coloured, dissolved organic matter (CDOM), which represents a fraction of dissolved organic carbon (DOC),contributes strongly to the absorption of blue light in Baltic waters. This makes the Baltic an idealtest site for deriving DOC concentrations from ocean colour imagery. Two hundred and five high resolution(1.3km) SeaWiFS images were processed using SeaDAS v.4.0 and combined into monthly composites of reflectance.A simple, in situ-generated reflectance ratio algorithm was used to derive CDOM absorption at 440nm (ag440),and an algorithm from the literature was applied to derive DOC concentrations, with a constant CDOM spectralslope coefficient of 0.019nm{^-1} to extrapolate to the required DOC-algorithm wavelength. Temporalresolution was restricted by cloud cover and by solar illumination conditions: only monthly composites fromMarch to October were practical. Surface DOC concentrations ranged between 4 and 5mgl^{-1}, with elevatedvalues in the cloudiest months (March and October). An increase in surface DOC lagged behind the annualcyanobacterial bloom, which peaked in July, by one month. Assuming a constant DOC profile, basin-integratedDOC estimates for the Baltic of 0.3{/pm}0.04Tg were obtained. The major contributions to error in thistechnique were evaluated.
