Near-real time measurements from the SmartBuoy

Mooring positions
Deploying the SmartBuoy
These measurements, from site A (near to the Liverpool Bar Light), will be used to assess the nutrient status and ecosystem response as part of the National Monitoring Programme.

The data are also being used for validating and testing ecosystem models.

You can view some of the data in near-real time by using the links below. If you require the data values please click on the CEFAS link.

Isle of Man long term data sets
The timeseries are continuous and ongoing and were initiated at Port Erin Marine Laboratory (formerly Port Erin Marine Biological Station), University of Liverpool.

Since the closure of Port Erin Marine Laboratory during 2006 the continuation of the dataseries has been undertaken by the Government Laboratory, Department of Local Government and the Environment of the Isle of Man Government.

Glider deployment
Glider deployment
Glider experiment, 26 October to 17 November 2005
An autonomous Glider was deployed in the Irish Sea, in an area to the south of the Isle of Man, It was setup to move in both the vertical and horizontal, whilst avoiding fixed objects (e.g. oil and gas rigs) and the major shipping lanes.
