BODC holds sea level data from all over the world in many formats. We are working on this portal, so eventually you will be able to search through all of BODC's sea level data holdings and, where possible, download the data.

There will be a map, so that you can search by geographical location, and a form to fill in, so you can specify the time period, the type of record (e.g. chart, digital) and the sampling interval you are interested in.

For the moment, listed below is information about where digital sea level data can be found on the BODC web site and some information on the analogue records we hold.

Digital data

Request processed data from the last three months (charges may apply)

Download processed data, up until three months ago, to allow for quality control

We also hold records of 1/4 hourly, 1/2 hourly, hourly and three hourly heights and visual observations. For more information on these or any other information not covered here, email the BODC Enquiries Officer.
