Fixed-point time series are an essential element of the global ocean observing system. These Eulerian Observatories are uniquely suited for fully sampling 2 of the 4 dimensions (depth and time), thus complementing other components of the observing system (satellites, floats, ships). They resolve a wide range of temporal variability and sample the water column from the surface to the bottom. Fixed-point stations will resolve multi-disciplinary variability and processes like CO2 uptake, biological productivity, fluxes of heat, freshwater momentum and other properties between the ocean and atmosphere, and seismic and biological activity on the bottom

An International Time Series Science Team has been created. Its membership is multidisciplinary, including geological, biological, chemical, and physical scientists whose interests extend from the ocean bottom to the air-sea interface. They have developed the background for time series as an element of the integrated global ocean observing system and are working on strategic plans to implement this element

While a great part of the network have been operated for a long time, access to data is not easy as they are spread in the different centers contributing to the project. One important task of the project is to improve data access throught GDACS and also to homogeneize QC procedures.



Temperature Timeseries at CIS sites from Sep 2005 to Sep 2006

The products that are available thought this project are:

  • in-situ observations of ocean/climate related quantities at a fixed geographic location/region , sustained and continuous, contributing to a long-term record at the site
  • as an alternate to a mooring, shipboard observations from regular occupation of a site as at Ocean Weather Stations, historical sites or sites where moorings have not been established provide an alternate method


Research & Development

R&D activities are carried out to document and when possible to homogenize quality control procedures among the different sites.
