2.2.4. Environmental context
For the Tara Oceans samples (Pesant et al., 2015), geo-localization and biogeochemical characteristics of the sampled seawater were obtained from PANGAEA (https://doi.org/10.1594/PANGAEA.875582). The environmental variables provided by OBA (Figure 2) were either classical oceanographic measures obtained in situ (e.g. depth, salinity, temperature, oxygen, chlorophyll a, etc.) or mesoscales features estimated from oceanographic models and remote satellite observations (e.g. nutrient concentration at 5m depth or net primary production). Estimated values are indicated by a star in the drop-down menu of bubble plot panels (Figure 2B and C). Descriptions of the environmental variables available in OBA and corresponding PANGAEA hyperlinks are provided in the OBA user manual hyperlinked from the OBA results page.
For each Malaspina-2010 sample, environmental variables collected as described in (Fernández-Castro et al., 2014; Logares et al., 2020; Salazar et al., 2015) were extracted from the metadata file found at:
