Southern Ocean Biogeochemical Float Deployment Strategy, With Example From the Greenwich Meridian Line (GO‐SHIP A12)

Abstract: Biogeochemical Argo floats, profiling to 2,000‐m depth, are being deployed throughout the Southern Ocean by the Southern Ocean Carbon and Climate Observations and Modeling program (SOCCOM). The goal is 200 floats by 2020, to provide the first full set of annual cycles of carbon, oxygen, nitrate, and optical properties across multiple oceanographic regimes. Building from no prior coverage to a sparse array, deployments are based on prior knowledge of water mass properties, mean frontal locations, mean circulati… Show more

“…The Southern Ocean is a critical region to the global carbon cycle, but our understanding of the regional carbon cycle is still limited. Observations have been highly seasonal until recently, where autonomous floats are starting to provide continuous coverage (Talley et al, 2019). The Drake Passage is the only region in the Southern Ocean with consistent year‐round sampling, making it an ideal region to investigate pCO 2 seasonality, but numerical models, including ours, still cannot fully reproduce the observed pCO 2 time series.…”

“…This study uses in situ data from autonomous biogeochemical floats deployed by the Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) project (Talley et al, 2019). SOCCOM floats measure temperature, salinity, pressure, dissolved oxygen, nitrate, pH, fluorescence, and backscatter over the top 2,000 m of the water column every 10 days.…”

“…Another promising development is the deployment of Argo floats equipped with ice avoidance software. These floats are also beginning to carry sensors that measure nitrate, oxygen, pH, and fluorescence, and several have already been deployed in the WG (Briggs et al, ; Talley et al, ). Adding the ability to acoustically track the location of these floats when they are under the seasonal ice will improve their utility (Chamberlain et al, ).…”
