As one of the four large JGOFS field elements, a network of Long-Term Time Series Observatories has been developed in order to document seasonal to decennal scale variations in key biogeochemical, physical and ecological parameters. Long-term time series measurements are crucial for characterizing the natural variability and secular trends in the ocean carbon cycle and for determining the physical and biological mechanisms controlling the system. Year-to-year variations in physics (e.g., upwelling, downwelling), bulk biological production, and ecological shifts (e.g., community structure) can drive significant changes in ocean carbon cycling and ecology. The biological and chemical responses to natural (e.g., ENSO, dust deposition events) and anthropogenic perturbations are particularly important with regard to evaluating the prognostic models used in future climate projections. Long-term time-series stations are also invaluable for developing and testing autonomous sensors and as focal points for process studies. The main stations are as follows:
|BATS -- Bermuda Atlantic Time-series Study|
DYFAMED -- DYnamique des Flux de mAtière en MEDiterranée
ESTOC -- European Station for Time-Series in the Ocean Canary Islands.
|HOT -- Hawaii Ocean Time series station|
|KERFIX -- Fixed time-series station in the Southern Ocean near the Kerguelen Islands|
|KNOT -- Kyodo North Pacific Ocean Time Series|
|OSP -- Ocean Station Papa|
|SEATS -- South East Asia Time-Series Station|
In addition, some other stations could be of interest to JGOFS scientists, either for their particularities or their historical value:
CARIACO -- Carbon Retention In A Colored Ocean Project
POGO Fixed-Point, Time-Series Initiative (Time Series Working Group)
The Partnership for Observation of the Global Oceans (POGO) is a forum
created by major oceanographic institutions involved in global observations,
scientific research, operational services, education and training and aiming
at the promotion of global oceanography, particularly the implementation of
an international and integrated global ocean observing system.

US NODC Coastal Ocean Time Series Database
The Coastal Ocean Laboratory of the US National Oceanographic Data Center (NODC) has begun a project for developing a prototype coastal ocean time series database (COTSDB). The primary objective of this project is to integrate coastal ocean time series observations from a variety of instruments with different resolution, accuracy and response to spatial and temporal variability into a common database.
