Kate Hendry – I’m a geochemist and oceanographer, and my research is geared towards understanding the behaviour of silicon, which is an important – but lesser known – nutrient in seawater. I’m the principal scientist of ICY-LAB, which means I’ll be responsible for the running of the project and the co-ordination of fieldwork. I’m lucky to have an excellent team of people to work with on such an exciting project!
Hong Chin Ng – I am interested in investigating the interplay between the climate system, the ocean system, the biosphere and the cryosphere, and understanding the implications of the current climate change on the other earth systems. Some of the forcing and feedback of these earth systems can be examined through the isotopic analysis of certain chemical elements in the nature, which provide information on natural processes such as biological productivity, continental weathering, and ocean circulation. I recently finished my PhD studies focusing on the analysis of the ratio of two uranium-series isotopes (231Pa/230Th) in the sediment, which is a promising proxy of Atlantic Ocean circulation rate. In the ICY-LAB project, I will be participating in the scheduled cruise work across the Labrador Sea, and planning boat work at coastal fjord system in Greenland. Subsequent isotopic analyses such as the Si isotope ratio (30Si/28Si) and the 230Th isotope (a proxy of sinking particle flux) on the acquired water and sediment samples will allow us to constrain the Si cycle at high latitudes with enhanced meltwater input under the current rapid climate change.
Laura Robinson – I am very excited about the opportunity to work in the ICY-lab team. It is a unique opportunity to explore the current and historic changes in the oceanography of the Labrador Sea. Over the last decade I have been involved in large scale ocean going expeditions to image map, image and collect deep sea corals. My research involves using the carbonate skeletons of these corals to establish how the ocean and climate interact. Previous work in the tropical Atlantic and the Southern Ocean has shown us that the deep interior of the ocean can change very quickly. The Labrador Sea is a location where subsurface waters form today, and there is a lot of debate about how much deep water formed here in the past. On this expedition I hope to be able to collect deep sea corals to explore this important question. You can see more about my research here.
Jemma Wadham – I’m a co-investigator on Project ICY-LAB. I’m a glacial biogeochemist, with an interest in improving our understanding of how glaciers and ice sheets interact with the rest of the planet and how this will change in a warming world. I’ve been working on the Greenland Ice Sheet since 2008, investigating the chemistry and nutrient content of runoff from the ice sheet and its impact upon the marine system. I’ll provide expertise to ICY-LAB regarding potential nutrient (and Silica) fluxes from the land to the ocean around Greenland.
ICY-LAB Cruise Science Partners
Marcus Badger – I’m an organic geochemist and paleoclimate scientist and I study ancient climates using molecular fossils. When an organism dies, often components of the organic remains are preserved in sediments. By analysing molecules characteristic of particular organisms or environmental conditions (“biomarkers”) we can reconstruct ancient environmental parameters. I love being at sea and this will be my third research cruise – and my second with Kate!
Adam Cooper – I’m a chemical oceanographer-in-training, currently completing a Masters degree at Southampton University. I hope to look into how the isotopic composition of phytoplankton is governed by ocean acidification in a warming world, and the related implications for marine communities. I will also assist with the greater water sampling efforts. This will be my third cruise opportunity, and I’m really excited to gain some more sea miles with a great team of scientists!
Sian Henley – I am a marine biogeochemist with a focus on nutrient and carbon cycling in the polar oceans. My role in the ICY-LAB project will be to measure the nitrogen and
oxygen isotope composition of nitrate to examine the supply, uptake and recycling of nitrogen in the Labrador Sea. We will combine our nitrate and silicon isotope results to describe the coupling of the silicon and nitrogen cycles in this dynamic, fast-changing and ecologically important region of the Arctic Ocean.
Veerle Huvenne – I am a marine habitat mapping expert, specialised in complex deep-sea ecosystems such as cold-water coral reefs, submarine canyons and seamounts. Creating reliable maps of biodiversity distribution is the first step towards the sustainable management of our oceans. To achieve this, I make use of the latest (robotic) technologies on offer: Remotely Operated Vehicles, Autonomous Underwater Vehicles, gliders… I use it all, and preferably all at the same time! For the ICY-LAB expedition I have a specific interest in the structure of any sponge communities and coral gardens that may be found on the Labrador seamounts, to compare them to similar habitats we’ve studied elsewhere in the N Atlantic, and to understand what are the environmental drivers that cause one area to be colonised by sponges, and another by corals.
Roo Perkins – I’m a biologist specialising in aquatic photosynthesis, being especially interested in how organisms cope with stress but still maximise productivity. I use variable chlorophyll fluorescence to investigate this and other processes of photochemistry, including photoacclimation and down regulation processes. I’ve worked primarily on microalgae and cyanobacteria, ranging from benthic mudflats, phytoplankton to stromatolites, but also worked on coralline macroalgae and seagrass. I love field work and this will be my fourth cruise, but the other three were all in the Bahamas!
Michelle Taylor – I’m a molecular ecologist and coral geek. I’m interested in how populations of deep-sea organisms are connected and how animals evolve in the deep-sea. Genetics are my tool of choice and I hope to be able to collect some very rare deep-sea corals, perhaps even a few new species too….
Tina van De Flierdt – I’m a geochemist and (palae)oceanographer with a keen interest to unravel past ocean circulation and climate relationships, as well as the history of continental ice sheets and their vulnerability to future climate change. I am excited to work with Kate and her team on ICY-LAB to better our understanding of the modern biogeochemical cycle of one of my pet elements, neodymium.
