Report on Argo float WMO 6901250 deploymentARGO ESPAÑA - IEO / 17 - 29Deployment for Argo floatWMO 6901250February 5, 2018A. González-Santana - P. Vélez-Belch́ıInstituto Español de Oceanograf́ıaDeployment DesignTaking into account the distribution of the Argo floats in the western Mediterranean,a gap was identified, south east Menorca island (Balearic archipielago). Thus, Argo Spainand SOCIB worked together to carry out a deployment of an Arvor - I float at the studyarea and thus, extending the coverage of the Argo network in the southern Mediterranean.The float was planned to be deployed on late June but the R/VCatamaran SOCIBbroke down during Canales survey. So, the deployment was carried out during BluefinTuna survey from the R/V Catamaran SOCIB under the supervision of SOCIB teamon July 10, 2017 with no issues. There is no CTD cast at the deployment location.Moreover, Coriolis was notified July 11, 2017 and all the information was registered atArgo Information Center database.

Technical information of the float.The checklist was firstly reviewed, full auto-test done on land and double checkedat the pre-deployment by Irene Lizarrán on land and Francisco Alemany on board.Parameters MC2, MC3, MC11, MC12, MC13, MC14 and MC15 were modified accordingto scientific requirements. The deployment was developed according to the nine dayssurface currents forecast. The estimated deployment position according to the predictionswas set southeast Menorca island as is shown in Figure 1 (yellow color). Deploymentoperator: Francisco Alemany.2Figure 1: Ocean surface currents forecast for WMO 6901250 from the SOCIB modellingfacility.IncidencesAfter the deployment on July 10, ARGO Spain waited some hours to make surethe float was working right. The float was drifting on surface under dangerous conditions(possible cruise crash and extra biodeposition). There was location signal by GPS everyhour but no profiles developed since the deployment. Romain Cancouët from Euro - ArgoERIC was called to give us some help. After some checks using NKE parser, the troublewas identified: ”It seems your float failed during autotest, because of internal vacuum,because the threshold is too low; this happens when the float is started after been exposedin high sun (boxes on the deck). It is in end of life (MC0=0)”. Once the problem wasknown, Arvor - I float was contacted and MC0 parameter was changed from 0 to 300.After this correction, WMO 6901250 developed its first profile on 6 August so far, afteralmost a month drifting on surface.3
