    Multidecadal changes in biology influence the variability of the North Atlantic carbon sink (2022)
    IOP publishing
    Details
    Publication Date: 2024-02-07
    Description: The North Atlantic Ocean is the most intense marine sink for anthropogenic carbon dioxide (CO2) in the world's oceans, showing high variability and substantial changes over recent decades. However, the contribution of biology to the variability and trend of this sink is poorly understood. Here we use in situ plankton measurements, alongside observation-based sea surface CO2 data from 1982 to 2020, to investigate the biological influence on the CO2 sink. Our results demonstrate that long term variability in the CO2 sink in the North Atlantic is associated with changes in phytoplankton abundance and community structure. These data show that within the subpolar regions of the North Atlantic, phytoplankton biomass is increasing, while a decrease is observed in the subtropics, which supports model predictions of climate-driven changes in productivity. These biomass trends are synchronous with increasing temperature, changes in mixing and an increasing uptake of atmospheric CO2 in the subpolar North Atlantic. Our results highlight that phytoplankton play a significant role in the variability as well as the trends of the CO2 uptake from the atmosphere over recent decades.

    Interpolated Global surface ocean carbon dioxide partial pressure and ocean-atmosphere fluxes 1992-2018, corrected for surface temperature deviations (2020)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: The data set consists of interpolated fields of global surface ocean partial pressure of carbon dioxide (pCO2sw) and the flux of CO2 between ocean and atmosphere, on monthly time and 1-degree latitude and longitude, between January 1992 and December 2018. The pCO2sw is interpolated to this grid from the data set of Holding et al: https://doi.org/10.1594/PANGAEA.905316, which is in turn derived from the the SOCATv2019 observational data (https://www.socat.info/) where the observations have been corrected to the surface subskin temperature using satellite-derived surface temperature products. The interpolation uses the neural net technique of Landschützer et al. ( Biogeosciences 10, 7793-7815, doi:10.5194/bg-10-7793-2013 2013). The ocean-atmosphere flux is then calculated, using the gas transfer equation with the gas transfer velocity parameterized as a function of wind speed and atmospheric mixing ratio of CO2, with a further correction for the cool (and salty) surface ocean skin. These corrections for near-surface temperature deviations increase the net negative (e.g. into the ocean) flux. Full details are given in the corresponding article in Nature Communications (doi:10.1038/s41467-020-18203-3) and its accompanying extended data.

    Hydrochemistry of water samples during Maria S. Merian cruise MSM60/1 (2023)
    PANGAEA
    Details
    Publication Date: 2024-05-22
    Description: The Bottle file contains data from the discrete samples taken on CTD casts, including data from the S/T/P/O sensor. Biogeochemical observations during this cruise include discrete measurements of the macronutrients nitrate/nitrite, phosphate and silicate, as well as oxygen by winkler titration.
