COSYNA (Coastal Observation System for Northern and Arctic Seas) is an operational coastal monitoring, forecasting and information system for the North Sea composed by fixed platforms, FerryBoxes, gliders and HF-radar systems. It is being developed by institutes of the German Marine Research Consortium (KDM) and collaborating institutions and is operated by the Hereon Research Centre. The infrastructure represents an investment of 9 M €. It was build up since 2007 and is fully operational since 2012.

COSYNA_GL is one of the 2 gliders of the system (TWR Slocum Electric, 100 m) equipped with CTD, Wetlabs ECO puck FLNTU (fluorescence and turbidity) and CDOM fluorescence.

Instrument Measured Parameter(s) Elevation / Depth Sampling Frequency of data recovery
CTD Conductivity, temperature, depth 0-100 m Depth 0.5 Hz Every 3-4 hours
FLNTU Fluorescence, turbidity 0-100 m Depth 1 Hz Every 3-4 hours
BB3SLO Backscatter 440, 532, 680 nm 0-100 m Depth 1 Hz Every 3-4 hours
FLBBCD Fluorescence, backscatter (600nm) and CDOM 0-100 m Depth 1 Hz Every 3-4 hours

  • In person/hands-on: the presence of the user group is required/recommended during the whole operation,
  • Partially remote: the presence of the user group is required at some stage e.g. installing and un-installing user’s equipment.

Unit of access (UA): month (minimum duration).

Hereon provides access to one of the two gliders of the fleet for autonomous operation at sea. Access to the Hereon glider by a user group is treated as a concession granted to use the infrastructure (one glider, prior contact to Hereon required to assure piloting and operation capabilities) in a dedicated experiment to collect specific data following the implementation of an automated measurement programme agreed between the user group and Hereon.

TNA projects supported by JERICO-NEXT:

A support team of technicians and scientists of Hereon will prepare the instrumentation; support operations at sea, including glider deployment; support in processing the data.
