Today we deployed a highly sensitive bottom pressure instrument from the Scottish Association of Marine Science (SAMS) that will takes measurements for the next 10 years. This instrument is one of a set of two designed to measure the sea surface height across the North Atlantic.

The difference in sea surface heights across the North Atlantic is currently measured by satellites and is used in the computation of the overall meridional water mass transport. By deploying these new instruments SAMS aims to make more accurate observations of this difference in sea surface heights so that scientists can better estimate the Atlantic circulation.
