From plankton to dolphins, CEFAS research cruise scientists encounter it all

Bournemouth University (BU) researchers Dr. Dan Franklin and Deborah Steele have joined forces with scientists from across Europe on a research cruise in the North Sea exploring the abundance and growth of plant cells (phytoplankton).

The research team conducted their study aboard the R.V. Cefas Endeavour, using specialised optical instruments called flow cytometers, which analyse thousands of cells per second.

Using this technology the scientists have built up a comprehensive picture of what grows where and how productive the different cells are.

This data will improve the way plant growth is seen by satellites and will help to map out fish production, which is ultimately dependent on phytoplankton growth.

Dr Franklin, a lecturer in the School of Applied Sciences, said: "We were exceptionally lucky with the weather and enjoyed calm seas throughout the cruise. Our track took us North from Lowestoft, across to the Dogger Bank, east into Dutch coastal waters before returning to Lowestoft via the Greater Gabbard wind farm in the Thames estuary. The fact that we had calm seas made the lab work much easier. I found the habitat complexity and biodiversity of the North Sea a revelation - everywhere was different. When not working long hours in the laboratory, we were fortunate to see plenty of wildlife such as whitebeak dolphins, various seabirds such as gannets and guillemots, and possibly minke whales and orcas."

The research trip was made possible by the generosity of CEFAS, the government laboratory responsible for monitoring fish stocks, promoting the sustainable use of marine resources and improving the marine environment. BU extends thanks to CEFAS for this opportunity.
