González-SantanaSistema de Observación y Predicción Costero de las Illes Balears - InstitutoEspañol de OceanografíaReport on Argo floatWMO 6901281 deployment1. Deployment designFollowing the Argo program goals, the float density criteria demands acoverage distribution of 3º x 3º grid cells (Fig. 1). In order to maintain theglobal Argo network coverage and taking in account the current distribution ofthe Argo floats, Argo España planned 1 float deployment in the Balearic seaarea after some gaps in the network were identified.Figure 1. Density of Argo observations in 2020. Deployments in the South Atlantic Ocean are needed if densityobservations goals want to be reached.As PI of the Canales Autumn 2020 cruise, Inmaculada Ruiz (SOCIB) wasrequested to lead the Argo deployment planning. The R/V SOCIB was plannedto carry out the research in the Balearic Sea, through Denia – Ibiza - Mallorca(Fig.2). Floats deployed at the Balearic Sea are occasionally driven out to shoreland, making this area a di cult region to observe continuously. The surveywas divided in several transects, which includes an ideal location for ArgoEspaña purposes. Station S2_05 was selected for the Argo float deployment.Report on Argo floatWMO 6901281 deploymentFigure 2. Canales Autumn 2020 cruise plan.2. Deployment dataFollowing the Argo program goals, the float density criteria demands acoverage distribution of 3º x 3º grid cells (Fig. 1). In order to maintain theglobal Argo network coverage and taking in account the current distribution ofthe Argo floats, Argo España planned 1 float deployment in the Balearic seaarea after some gaps in the network were identified.Information of the float deployment is shown in this paragraph.WMO 6901281. The following table contains all the data of the WMO6901281 deployment during Canales Autumn 2020 cruise, deployed at S2_05station (Fig. 2). No troubled issues during the deployment were reported. CTDcast is available at the deployment location. Coriolis was notified on Nov 04,2020 and all the information was registered at the Argo Information Centerdatabase. The data is free and publicly available through the Argo data stream:http://www.oceanografia.es/argo/datos/floats/6901281.htmlReport on Argo floatWMO 6901281 deploymentDATE AND TIME 2020 - 11 - 04 / 11:26 UTCDEPLOYMENT LOCATION 39°01.053’ N0°43.149’ EDEPLOYMENT PLATFORM R/V SOCIBCRUISE ID Canales Autumn 2020FLOAT OWNER SOCIBPLATFORM TYPE NKE Arvor - ISERIAL NUMBER AI2600-19EU023TRANSMISSION SYSTEM IRIDIUMPARKING DEPTH (m) 1000PROFILE DEPTH (m) 2000DEPLOYMENT DEPTH (m) 960WEATHER CONDITIONS Wind – rippled surfaceDEPLOYMENT OPERATOR Nikolaus Wirth – Irene Lizarán - LaraDíaz-BarrosoTable 1.
