Global Sea Levels

Synopsis: To measure mean sea level, the effects of tides and weather must be accurately known and the effects of land movements and ice cover can dominate local measurements. Uncertainties about future rates of rise in sea level are addressed by looking at fluxes of carbon to the deep sea (Joint Global Ocean Flux Study) and by direct monitoring of sea level changes with tidal gauges, bottom pressure recorders and satellite altimentry. It is not yet known if the greenhouse effect is causing sea level to rise more rapidly.

Notes: NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
