They're going to be blogging their way from Britain to the Falkland Islands on the Atlantic coccoliths blog, hosted on the Natural History Museum's website. Here's the blurb at the top of the blog:
This blog follows Museum researchers Martine Couapel and Jeremy Young as they collect minute plant plankton, called coccolithophores, in the Atlantic Ocean. They are taking part in the AMT18 (Atlantic Meridional Transect 18) oceanographic research cruise. It will take them from Britain to the Falkland Islands and will last 5 weeks.
The aim of their research is to build a more complete picture of the current distribution of coccolithophores in the Atlantic. Scientists are interested in finding out how coccoliths will be affected by global warming and by increasing levels of acidity in the ocean. Jeremy and Martine's research will provide baseline information about coccolithophores that future studies can be measured against.
