Fostering the establishment of a global ocean observing system, Walter Munk defined the 20th century as the “century of undersampling”, and this is especially true for marine biogeochemical observations. Biogeochemical Argo is bringing us into a new era that is characterized by an unprecedented availability of high-resolution biogeochemical profiles, delivered throughout the year and globally distributed. Thanks to these observations, the dynamics of ocean carbon, oxygen, nutrients, primary producers, pH, and bio-optical properties can be examined in all three spatial dimensions. The increased availability of these observations allows us to unravel biogeochemical processes and to develop and validate hypotheses across a range of spatial and temporal scales. These new observations will also substantially improve the quality of biogeochemical models by allowing vigorous validation, improved parameterizations, and formal data assimilation.

In this special issue, we welcome contributions leveraging the high data availability provided by BGC-Argo floats combined with theoretical or numerical models, data assimilation, machine learning, multi-platform sensors, or other novel interpretative methodologies that expand the surface view of ocean ecosystem dynamics into the vertical dimension.

The purpose of the special issue is to collect the high-quality contributions presented at the oral and poster sessions entitled “Biogeochemistry in the BGC-Argo Era: From Process Studies to Ecosystem Forecasts” held at Ocean Sciences Meeting 2020 in San Diego. Moreover, the special issue is open to other relevant contributions.
