18-Jan-2012 The mooring line has parted and the surface buoy has moved off station. No further data is being transmitted from the subsurface sensors. The surface buoy has been recoverd.

After the retirement of the Station M platform vessel Polar Front at the end of 2009, Station M has metamorphosed into a multidisciplinary mooring. It is now sending data in real time which can be viewed by clicking HERE

Station Mike has been collecting data on seawater temperature, salinity since 1948 and on oxygen concentration since the 1950s. During 2009 metadata describing the data were collated and the data made available through these pages in OceanSITES format. Below are graphs of the data after undertaking some further gross range checks.

EuroSITES funds have supported the development, testing and deployment of a sub-surface mooring equipped with physical measurement sensors (temperature and conductivity) to 2000 m and oxygen optodes at 50 and 2000m. In addition, a new winch was mounted on to Ocean Weather Station Mike to enable a new CTD system to be installed. Further work was also undertaken at Station Mike to provide access to real-time data to EuroSITES.

Unfortunately the funding for the ship Polar Front was withdrawn in 2009 and Polar Front is no longer available as the Station Mike platform. Moorings to replace some of the Station Mike functionality have been designed and the sub-surface element of the observatory was deployed in February 2010. It is planned to deploy a configuration in Spring 2011 which will be full depth and have both a surface buoy carrying a meteorological package and also a lander element on the sea floor.
