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!
Claire Goodwin – I am a marine biologist who specialises in sponges. I’ll be joining the cruise from Canada where I manage a marine research museum (the Atlantic Reference Centre) at the Huntsman Marine Science Centre. Most of my previous survey expeditions have involved much shallower waters and sampling by SCUBA diving so I am looking forward to working in deeper waters with the ROV. Hoping to find lots of lovely sponges – maybe even some species new to science – and looking forward to working with the ICY-LAB team to find out about the role sponges play in the silicon cycle.
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.
Tim Culwick – I am a PhD student at the University of Bristol, supervised by Kate Hendry. My research focused on nutrient cycling by sponges (Porifera) in the deep ocean. I am describing and cataloguing sponges from this summer’s cruise. I will also be creating mathematical models of the sponge’s structure to look at their biomechanics, and the fluid flow around them. I want to find out about the biological and environmental factors limiting growth, body size and morphology.
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.
Steph Bates – I’m a research technician in isotope biogeochemistry – in other words, I get to help with the science fun by supporting other scientists in my research group with laboratory work, archiving and fieldwork preparations. On this expedition, I’ll be working as a laboratory manager, assisting with sample collection and doing titrations to measure how much oxygen is dissolved in the seawater. This will be my second time at sea and I am thrilled to be going back!
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.
Shannon Hoy – I’m a Graduate Student at the University of New Hampshire’s Center for Coastal and Ocean Mapping (CCOM) supervised by Dr. Brian Calder. Here we learn all things mapping from developing acoustic systems to turning the data into nautical charts. My role on the ship will be overseeing the mapping operations (alongside Veerle) to produce maps to be used for scientific operations and interpretation. Though I love all things mapping, I have a Bachelor’s degree in Marine Biology and worked on sediment cores at the U.S. Geological Survey, so I will definitely be getting my hands dirty while on board!
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.
Allison Jacobel – I’m an isotope geochemist who studies paleoclimate. Specifically, I’m interested in the record of past climate preserved in marine sediments and what it can tell us about how the Earth moves between glacial and interglacial climate states. My PhD work focused on using isotopes of uranium (U), thorium (Th), oxygen (O), and carbon (C) to understand the role of the tropical Pacific Ocean in changing climate states and I’m excited to apply some of the same tools (proxies) to study the Labrador Sea. This will be my third cruise and I’m looking forward to reuniting with many of the people who made the last one so much fun!
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!
Rebecca Pickering – I’m a biogeochemistry PhD student at the Dauphin Island Sea Lab and University of South Alabama, supervised by Dr. Jeffrey W. Krause. My dissertation research focuses on biogeochemical silicon cycling at the sediment water interface. Specifically, reverse weathering processes, production and dissolution of biogenic silica, natural abundance and fractionation of silicon isotopes and sediment sorption capacities. On the cruise, I will be measuring biogenic silica production using the radioisotope 32Si, as well as measuring chlorophyll fluorescence. This will be my third cruise this year and I’m looking forward to working outside of the Gulf of Mexico.
George Rowland – I’m a geochemistry PhD student at the University of Bristol, supervised by Kate Hendry and Laura Robinson. My research project focuses on reconstructing the flux of terrestrial material from continents to the oceans over the past ~25,000 years. To do this I look at deep sea sediments, measuring U and Th isotopes, organic molecules derived from terrestrial plants, and a host of other geochemical parameters that can provide insight into the past climate. On the cruise I’ll be helping with the sediment sampling and anything else I can lend a hand to. This will be my very first research cruise so I’m hoping to find out what it’s all about!
Ana Samperiz – I’m an MRes student at the University of Bristol, and my supervisor is Laura Robinson. I find really interesting how ocean and climate systems are connected, and in my research I’m trying to find out whether Stylasterid corals (very understudied but extremely cool and beautiful family of stony corals!) are suitable as paleoceanographic archives. This is going to be my first research cruise experience and I hope to collect more deep-sea corals to expand my research and also to give a hand wherever is needed – and so I’m sure I’ll learn a lot!
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.
James Williams – I’m a geochemist and micropalaeontologist in the first year of my PhD at Cardiff University. My research investigates the spatial and temporal patterns of glacier and ice sheet melting along the Antarctic Peninsula over the last 2,000 years. To do this, I utilise proxy records within marine sediment cores collected from the continental shelf. These include species assemblage counts and stable oxygen isotopes within the biogenic silica of diatoms. My role in ICY-LAB will be to assist with sub-sampling of marine sediment cores and to provide some insight into the phytoplankton of the Labrador Sea. I will also be a helping hand to anyone that needs me. I am itching to get back to sea having sailed before.
