Report on the Argo float  deployments of POSEIDON cruise 		1         Report on Argo float deployments of POSEIDON cruise    ARGO ESPAÑA – IEO / 19 – 52  Argo float deployment for WMO 6901257, 6901259, 6901268 and 6901272.   June 19, 2019     A. González-Santana - P. Vélez-Belchí  Instituto Español de Oceanografía    Report on the Argo float  deployments of POSEIDON cruise 		2   1. Deployment design  Following the Argo program goals, the float density criteria demands a coverage distribution of 3º x 3º grid cells (Fig. 1). Due to many causes, there currently are ocean areas with lack of observations, as it happens in the Southern Ocean and South Atlantic Ocean. There are still gaps with 0 observations/month. Argo deployments in areas as the South Atlantic Ocean, become crucial to extend the network and cover this lack of observations. In order to maintain the global Argo network coverage and taking in account the current distribution of the Argo floats, Argo España planned 4 float deployments in the South Atlantic ocean.   Figure 1. Density of Argo observations in the 2019 May vs the Argo 2020 challenge. Deployments in the South Atlantic Ocean are needed if density observations goals want to be reached.  As PI of the POSEIDON cruise, Jesús Arrieta (Spanish Oceanographic Institution - IEO) was requested to lead the Argo deployments planning. The R/V Sarmiento de Gamboa was planned to carry out the research at the South West Atlantic Ocean. The survey included 4 ideal locations to cover the dramatic lack of observations per area, one of them slightly further north of the equator.

Report on the Argo float  deployments of POSEIDON cruise 		10 D. Floats configuration  Floats configuration was set as default by NKE for all the floats. “MC” parameters (table 5) were set according to the scientific requirements and the oceanographic area of study (Atlantic Ocean). The floats will dive up to 2000 m depth carrying out cycles of 10 days, with a parking depth of 1000 m.   Table 5. Configuration sheet for all the floats deployed during POSEIDON cruise.  E. Acknowledgements  Argo España would like to thank Jesús Arrieta, Eugenio Fraile, Alba González and the crew of the R/V Sarmiento de Gamboa, who cooperated for the success of the mission.  These Argo floats have been co - financed by FEDER funds from “Programa Operativo Crecimiento Inteligente 2014 – 2020”.
