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:
