Microscopic ocean algae called coccolithophores are providing clues about the impact of climate change both now and many millions of years ago. The study found that their response to environmental change varies between species, in terms of how quickly they grow.

Chocolate and diamonds

Diamond

Scientists based at the National Oceanography Centre, Southampton have discovered a previously unrecognised volcanic process, similar to one that is used in chocolate manufacturing, which gives important new insights into the dynamics of volcanic eruptions.

Geoscientists explain differences between large Sumatran earthquakes

Geophysical equipment (‘airguns’) being deployed

University of Southampton scientists based at the National Oceanography Centre, Southampton, along with US and Indonesian collaborators have uncovered clues as to why some undersea earthquakes generate huge tsunamis. Their findings may help explain why the 2004 Sumatra ‘Boxing Day Tsunami’ was so devastating.

Celtic Sea cruise diary

Prof. Jonathan Sharples by the RRS Discovery at the King George V dock, Glasgow

A research cruise to the Celtic Sea sails on Wednesday 2 June 2010. The Celtic Sea is located in the North Atlantic Ocean between southern Ireland and southwest England (between approximately 48° and 51.5°N latitude and 5° and 12°W longitude). Professor Jonathan Sharples of the National Oceanography Centre is on the cruise and will be writing a diary.
