Fifty-year changes of the world ocean's surface layer in response to climate change
<p>This object includes two files. One (GlobalML_Trend_1970_2018.mat) contains the 1970-2018 trends of mixed-layer depth, 0-200 stratification, and pycnocline stratification, as described in: Sallée, J.B., Pellichero, V., Akhoudas, C., Pauthenet, E., Vignes, L., Schmidtko, S., Naveira Garabato, A., Sutherland, P., Kuusela, M., 2020, Fifty-year changes of the world ocean’s surface layer in response to climate change, 591, 592–598, https://doi.org/10.1038/s41586-021-03303-x. The second one (<a href="https://zenodo.org/api/files/15c80d5f-a6f9-4b7b-bde1-12de43732195/GlobalML_Climato_1970_2018.mat">GlobalML_Climato_1970_2018.mat</a>) contains a climatology of mixed-layer depth based on the same methodology as in Sallée et al., 2021 (nature; doi:https://doi.org/10.1038/s41586-021-03303-x) but without regressing a trend. The climatological field is therefore different than in the paper; more robust in region where trends are unphysical (e.g. winter high latitude)</p>

Dataset for the submitted manuscript titled 'Response of Southern Ocean Resource Stress in a Changing Climate'
<p>Netcdf output files of Primary Production, carbon export, Fe and Mn limitations, and deficiencies from PISCES-QUOTA model with Mn limitation (described in Anugerahanti and Tagliabue, 2023) forced by historical IPSL CM5A climate model simulation (1850-2005) and RCP8.5 high emission IPSL CM5A simulation (2005-2100) on the ORCA2 grid, as described and discussed in Anugerahanti and Tagliabue, in the manuscript submitted for Geophysical Research Letters. Due to the large size of the files, this has been collated to only contain surface/ upper 100m south of 40S. </p>
Climate transition at the Eocene - Oligocene influenced by bathymetric changes to the Atlantic - Arctic oceanic gateways
<p>This data includes input and output fields of the Norwegian Earth System model simulations targeting the Eocene-Oligocene boundary, and the data accompanies a scientific article with the same name (DOI 10.1073/pnas.2115346119). This data is aimed to provide users enough data to reproduce the figures appearing in the article and to analyze the steady state behavior beyond what is discussed in the article. We also provide the ocean bathymetry and atmospheric topography that allows others to create a model setup similar to what is used in the article.</p> <p>For most files there are two output periods 1450-1500 is a common period for the experiments: Late Eocene and cases 1-5. This period the average over the last 50 years of the experiments that were branched of the common spinup at year 1000. The latter period 2650-2700 includes continuation of the Late Eocene and Case 2 simulations and their lower CO2 counterparts (branched of from their parent simulations at year 2000). For more information of the simulations and the setup, we refer to the parent article.</p> <p>In addition to the output files, we also share the grid files of the ocean model (grid*.nc) and the topography used by the atmospheric model (ATM_TOPO.nc). Note that we did not change the land mask between the experiments which is why there is only one ATM_TOPO, but one grid file per each experiment.</p>

<p>This dataset comprises the output from simulations with the coupled climate model FOCI (Flexible Ocean and Climate Infrastructure, Matthes et al., 2020) used in the analysis presented in the study by Ivanciu et al., 2021 “Twenty-first century Southern Hemisphere impacts of ozone recovery and climate change from the stratosphere to the ocean”. Four ensembles of three simulations each were performed: FixODS (II012, II014, II016), FixGHG (II013, II015, II017), INTERACT_O3 (SW128, II010, II011) and PRESC_O3 (JH027, II037, JH039). A detailed description of the simulations can be found in the above-mentioned manuscript.</p>

Phytoplankton life strategies, phenological shifts and climate change in the North Atlantic Ocean from 1850‐2100
<p>Supporting data for the article entitled 'Phytoplankton life strategies, phenological shifts and climate change in the North Atlantic Ocean from 1850-2100'.</p> <p>Article abstract: Significant phenological shifts induced by climate change are projected within the phytoplankton community. However, projections from current Earth System Models (ESMs) understandably rely on simplified community responses that do not consider evolutionary strategies manifested as various phenotypes and trait groups. Here, we use a species-based modelling approach, combined with large-scale plankton observations, to investigate past, contemporary and future phenological shifts in diatoms (grouped by their morphological traits) and dinoflagellates in three key areas of the North Atlantic Ocean (North Sea, North-East Atlantic and Labrador Sea) from 1850 to 2100. Our study reveals that the three phytoplanktonic groups exhibit coherent and different shifts in phenology and abundance throughout the North Atlantic Ocean. The seasonal duration of large flattened (i.e., oblate) diatoms is predicted to shrink and their abundance to decline, whereas the phenology of slow-sinking elongated (i.e., prolate) diatoms and of dinoflagellates is expected to expand and their abundance to rise, which may alter carbon export in this important sink region. The increase in prolates and dinoflagellates, two groups currently not considered in ESMs, may alleviate the negative influence of global climate change on oblates, which are responsible of massive peaks of biomass and carbon export in spring. We suggest that including prolates and dinoflagellates in models may improve our understanding of the influence of global climate change on the biological carbon cycle in the oceans.</p> <p>The data provided here are the observed and modelled abundances (oblate and prolate diatoms and dinoflagellates), the observed and modelled environmental data (compiled data for sea surface temperature, Surface Downwelling Shortwave Radiation and disolved nitrates concentrations) in the North Sea, the North-East Atlantic and the Labrador Sea, and the phenological indices for the three different phytoplanktonic groups (i.e. oblate and prolate diatoms and dinoflagellates) and the three warming scenarios (the low, the medium and the high warming scenarios; SSP1-1.2.6 SSP2-4.5 and 5-8.5 respectively). The phenological indices are the maximum abundance, the day where the maximum abundance is reached, the day where the seasonal reproductive period is initiated and the day where it is terminated, the seasonal duration and the mean annual abundance. </p>
