Connecting Glider Data Flows in Europe and Beyond Networking the glider community HCMR’s glider team – Current status and data management scheme Evi Bourma, Leonidas Perivoliotis, Hellenic Centre for Marine Research (HCMR), Athens, Greece Euro. GOOS glider data management task team meeting, th th 18 to 20 of September, Genova, Italy

Status and role of the glider group HCMR role: Operator, Data Assembly Center, Mon.

Status and role of the glider group HCMR role: Operator, Data Assembly Center, Mon. GOOS Regional Data Center Current number of platforms: • 1 Sea. Explorer, maximum depth: 700 m, Scientific payload: CTD, Dissolved Oxygen • 1 Sea. Explorer X 2, maximum depth: 1000 m, Scientific payload: CTD, Dissolved Oxygen Another 1000 m glider equipped with heavier scientific payload (Chlorophyll-A/Turbidity pack, p. CO 2) is expected to be purchased during 2019. Number of people involved in running the system: • 2 engineers (1 dedicated) 4 available pilots • 2 physicists • 2 oceanographers • 1 IT 4 missions in the Cretan Sea since November 2017 (Continuous sampling of the same track in order to establish an endurance line. ) Future plans: North Aegean (trace BSW) Ionian - Possible collaboration with Italian (OGS) team Euro.

Problems or issues identified around glider data flow and management Ø Near real time

Problems or issues identified around glider data flow and management Ø Near real time data flow: gaps to the transmission of RT data due to satellite connection, affected by various factors (e. g. weather, sat trajectory ). Ø Delayed mode data management: Implementation of a robust scheme for data comparison from different sources – Different versions of the same dataset should be available under different level of quality control. Ø Existing tools for glider data management: Complementarity needed between the available tools. Complete process usually requires more than one tool to be used. Ø The release of the glider data in more than one format is necessary in order the maximum compatibility to be ensured (CMEMS- profiles, EGO – Timeseries, etc. ) Euro.
