We are a group of scientists from different institutions around the UK hoping to combine our knowledge of the biology, chemistry and physics of the Arctic Ocean. Our aim is understand how climate changes in the Arctic will affect the ecosystems that live there.
Here is an introduction to the scientists involved in this cruise:
Dr Robyn Tuerena, marine chemist, University of Edinburgh
Robyn is interested in how life in the ocean is fuelled by the natural fertilizers of the ocean, nutrients. Nutrients are vital for the growth of plants which fuel all life in the ocean. She will be collecting samples to look at how the levels of nutrients vary across the Arctic, with sources from the Pacific, Atlantic and Arctic rivers. She will be investigating how nutrients limit the growth of plants and how this may change in relation to climate change.
Dr Louisa Norman, marine biogeochemist, University of Liverpool
Louisa is the team co-ordinator – and is the most organised member of the team! She is in charge of getting the majority of kit (and people) prepared for a large number of scientific cruises which are taking place in the Arctic over a two year period. She will also be analysing samples of the plants at the base of the food chain to understand more about where plants get their nutrients and carbon from.
Dr Jo Hopkins, marine physicist, National Oceanography Centre
Jo is the resident physicist in a group of scientists which mainly consists of biologists and chemists. She will be looking at data produced on the ship which tells us about the temperature and salt content of the water and therefore its density. Using this information we can look at the currents in the ocean and how they move both in and out of the Arctic from the Atlantic Ocean.
Dr Camille De la Vega, marine biologist, University of Liverpool
Camille will be looking at the Arctic food web from samples of the floating plants in the Arctic (algae), all of the way up the food chain, to seals, some of the top predators in the Arctic. This information will be used to see how the Arctic habitat is responding to climate change, and whether the structure of the Arctic food web is being affected.
Elliott Price, University of Liverpool, PhD student
During his PhD, Elliott will be studying zooplankton, the insects of the sea. He will be collecting samples from the ocean using nets and identifying species using a microscope at sea.
Celeste Kellock, University of Edinburgh, masters student
Celeste will be investigating how the amount of carbon that is dissolved in seawater in the Arctic varies. This can depend on the biological uptake of carbon dioxide by plants, exchange with the atmosphere and the inputs from coastal areas and sea ice.
Emma Burns, University of Manchester, PhD student
Emma is studying the seafloor sediments to look at where the biological material in sediments come from. She will try to work out the origin of organic matter, whether it is from the land or the sea.
