JC31: The 'ingredients' of the Southern ocean


Who's who in the scientific team

Elaine McDonagh

Elaine is a physical oceanographer and Chief Scientist for JC31. She works for the National Oceanography Centre in Southampton and this is her fourth Southern Ocean cruise. Elaine's interest is in ocean circulation. Elaine has coordinated planning and preparations for JC31. At sea she will organise the science and liaise with the technical teams and Captain and crew to ensure the science plan is delivered.

Yueng-Djern Lenn

Dr Yueng-Djern Lenn is currently a Postdoctoral Researcher at the School of Ocean Sciences, Bangor University in Wales. She is an observational oceanographer with an interest in the dynamics of the Polar Oceans and their role in global climate.  Most recently, she has been investigating mixing processes in the Arctic Ocean and shelf
seas, while maintaining an on-going interest in Southern Ocean dynamics.

David Hamersley

David is a recent addition at NOCS.  Having graduated from Swansea University with an MSc in the field of climate change he is now working as a research assistant focusing on aspects of physical oceanography. During the cruise he will be measuring the salinity of the water samples collected from different depths in the water column and also operating the LADCP (Lowered Acoustic Doppler Current Profiler).  This will be his first research cruise, but he will also be taking part in JC32 at 24°S across the South Atlantic when JC31 has finished.  He is really looking forward to this experience despite the fierce reputation of the Southern Ocean.  Hopefully we will get lucky and see some Southern Ocean wildlife and icebergs!

Anastasia Charalampopoulou

Anastasia is a PhD student at National Oceanography centre, Southampton. She is investigating how a more acidic ocean, due to increasing CO2 emissions, might affect coccolithophores – a group of calcifying phytoplankton. This cruise is of particular interest to her, as high latitude regions will be the first to be affected by ocean acidification.

Harry Bryden

Harry Bryden participated in a previous expedition across Drake Passage in 1976 as part of the International Southern Ocean Studies (ISOS) project to measure the flow of the Antarctic Circumpolar Current.  In addition to longstanding interests in the dynamics of the Antarctic Circumpolar Current, he has also worked on the exchange between the Atlantic and Mediterranean through the Strait of Gibraltar and the role of the ocean in global climate and climate change.  He teaches oceanography at the University of Southampton.

Mike Lucas  

Mike graduated with a PhD from the University of Wales (Bangor) in 1979. After a post-doc at Duke Marine Labs in N. Carolina, he spent time at the Plymouth Marine Labs and at the University of Cape Town before joining NOC (SOES, GDD, OBE) in 2001 where he worked on phytoplankton ecology & biogeochemical cycles. He returned to the Zoology Department, University of Cape Town in Jan. 2008 where he pursues similar interests, particularly in the Southern Ocean.  He co-supervises two talented and feisty PhD students who are on this cruise - Ms. Sophie Seeyave and Ms Anastasia Charalampopoulou.  His role on this cruise will be to assist Anastasia with her measurements of calcification rates - and generally do what he’s told!

Jennifer Riley

Jen has just started her PhD at the National Oceanography Centre looking at the effects of changing ocean chemistry and the implications for the biological carbon pump. This will be the first time she has been to the Southern Ocean and she is looking forward to hopefully seeing icebergs, penguins and whales. On the cruise she will be working as part of the UEA team taking measurements of the carbonate chemistry in the waters across the Drake Passage. When not taking chemistry measurements she is hoping to be able to filter for the plankton in the surface ocean contributing to the biological pump.

Sophie Seeyave

Sophie Seeyave is a PhD student at NOCS, studying the nitrogen nutrition of Harmful Algal Blooms, also known as red tides because of the water discolouration they produce. This involved research trips to South Africa and N-W Spain, which are similar systems because they are both
affected by the upwelling of deep, nutrient-rich water to the surface.  Her research interests lie in the physiological adaptations displayed by phytoplankton, with respect to nutrient acquisition and light harvesting, which allow them to thrive in a particular environment and outcompete other species.  On this cruise, she will be measuring the uptake of nutrients and light-harvesting efficiency of phytoplankton in a very different environment to those she is used to!

Karel Castro Morales

Karel is a Mexican oceanographer currently enrolled in the 3rd year of a PhD degree at the University of East Anglia, Norwich, UK.  She is interested in measuring the gases dissolved in the seawater, its role in the oceanic biogeochemical cycles and interaction with the atmosphere. This is the third time she will have been down to Antarctica, but every time she is amazing by what you can see and find in the coldest continent of the world.  

Lesley Allison

Lesley is a PhD student at the University of Reading, and this is her first research cruise. Her thesis looks at the circulation in the Southern Ocean from a theoretical viewpoint, so she thought it was about time that she got out of the office and experienced the real thing!

Dorothee Bakker

Dorothee Bakker is a marine biogeochemist in the School of Environmental Sciences at the University of East Anglia in Norwich. She has a strong interest in the processes affecting the carbon cycle and the air-sea flux of carbon dioxide (CO2) in the Southern Ocean, notably iron limitation, sea ice, ocean physics and ocean acidification. During JC31 Dorothee leads the CO2 team, which determines inorganic carbon parameters across the two Drake Passage sections. Combination of these measurements with other data collected on board will allow quantification of natural and anthropogenic carbon transport across the sections.

Mary Bryden

Mary is a Research Assistant who will be mainly involved with the processing and calibration of the Seabird CTD. She has worked previously at the Woods Hole Oceanographic Institution.

Maria Salta

Maria Salta completed her BSc and MRes in Marine Biology – Oceanography (NOC, UoS). Currently she is a PhD student in the University of Southampton collaborating between nCATS (national Centre for Advanced Tribology, Southampton) and the NOC. She is interested in the antifouling properties found in marine organisms as well as understanding their ecophysiology.


I graduated in Chemistry at Insituto de Química (University of San Paolo)  and PhD in Chemical Oceanography at Insituto Oceanográfico at the same university. My thesis focus on evaluating phosphorus cycle through its chemcal speciation in sediments and relationship with bottom water parametres in shallow subtropical estuaries. Moreover I have done chemical speciation in other ocastal environments, such as Antarctica (Admiralty Bay locatede at King George Island), Southeastern and Sotuh Continental Shelf.

Heiko Moossen

Heiko Moossen is a PhD-student at the University of Glasgow. He is an organic geochemist and is interested in the developement and application of biomarker (molecular fossils)  proxies to use for palaeoclimate reconstruction. On this cruise, which is his first, he will be filtering seawater to obtain particulate organic matter (POM) which is suspended in the water column. He is specifically interested in a group of molecules called Alkenones which are produced by coccolithophores and which can be used to determine changes in palaeo sea surface temperature (SST).

Andrew Brousseau

Andrew Brousseau is a recent graduate of the Univeristy of Massachusetts.  He studied the abiotic and biotic systems and their interactions with the Earth.  He is looking to work on the integration of humans with the environment.  He enjoys being outside as well as inside.

Libby Jones

I'm a third year PhD student in marine biogeochemistry at the University of East Anglia. My research is investigating the marine carbon cycle in the Scotia Sea, Drake Passage and the west Antarctic Peninsula. I am particularly interested in the role of sea ice and ocean acidification in Southern Ocean carbonate chemistry. I love to travel and experience other cultures, landscapes and wildlife, always taking my camera along for the ride!
