Using sophisticated methods of dating rocks, a team including University of Southampton researchers based at the National Oceanography Centre, Southampton, have pinned down the timing of the start of an episode of an ancient global warming known as the Paleocene-Eocene thermal maximum (PETM), with…

Today’s blog is written by the two other people responsible for measuring seawater carbon chemistry: Cynthia Dumousseaud and Victoire Rerolle from the National Oceanography Centre Southampton.First let’s come back to the chemistry. Carbon is dissolved in seawater in different forms that can…

We will return to yesterday’s theme – carbon chemistry of seawater – tomorrow, but today’s blog is about pteropods.The exciting event today was a chance finding of pteropods in one of the CTD water sampling bottles. When we were filtering the seawater (straining it through an extremely fine mesh to…

A fundamental prerequisite for ocean acidification work is to accurately measure seawater pH and carbon chemistry. The basic objective of ocean acidification research is to work out the impact of inputting extra carbon dioxide into seawater.We want to establish the effect of these chemical changes…

We are now in weather area Rockall, to the west of Ireland. Today has been a gruelling day because, in addition to normal tasks, we also started analysing some of the water we have been carrying with us since Scotland.In Wednesday’s blog the setup of the bioassays was described. On Wednesday, the…

As promised yesterday, today’s entry focuses on cold-water corals and is written by Laura Wicks and Sebastian Hennige, who, together with Murray Roberts (all from Heriot-Watt University), are carrying out the work.Although the mention of coral reefs may conjure up images of tropical seas and sandy…

Today has been a red-letter day in the cruise calendar, with two major activities starting up. Through the first half of the night the ship steamed further north towards the Outer Hebrides, in the weather forecast area “Hebrides”, unsurprisingly. Eventually we arrived at our target site close to…

The Shipping Forecast Cruise?We are almost getting into a routine now as we get through the second cruise day, settle into our scientific nests, complete our fourth CTD station, start preparations for the first deck incubation experiment, and converge on Mingulay for the deep-sea coral reef…

The UK research vessel RRS Discovery left Liverpool yesterday on the first research cruise specifically to study ocean acidification in European waters. Twenty-four scientists from eight different UK institutes, led by the National Oceanography Centre Southampton, will carry out the science.The…

The present rate of greenhouse carbon dioxide emissions through fossil fuel burning is higher than that associated with an ancient episode of severe global warming, according to new research. The findings are published online this week by the journal Nature Geoscience. Around 55.9 million years…

Today we left the dock in Liverpool quite early, at about 8:30. We were delayed slightly as waited to exit through a tidal lock. Then we were on our way, out into the turbid, brown-coloured waters of Liverpool Bay where we carried out our first CTD station at about midday.A CTD station is where the…

On the 6 June 2011, the UK research vessel the RRS Discovery left Liverpool docks to embark on the first research cruise in a large UK programme studying the impacts of ocean acidification.On the cruise, researchers are investigating the impacts of changing seawater chemistry on:marine organisms…
