Earlier this summer a group of Liverpool Ocean Scientists spent 7 weeks on a research cruise in the sub-tropical North Atlantic Ocean. The focus of the research was on the effect that the steeply-sloping seabed of the mid Atlantic Ridge has on turbulence and mixing in the overlying water. Our hypothesis is that the extra mixing generated by the ridge drives more nutrients from the deep ocean up towards the sea surface, where they can be used by the plankton. In the seminar I will provide the background to why we think that is a reasonable hypothesis, along with some of the preliminary results that indicate we are on the right track. I’ll also spend time explaining more generally about the sorts of measurements we make from research ships, and the challenges of spending that much time at sea.
