I am an observational biogeochemist with a main focus on the factors that control the downward flux of material from the top of the ocean into the interior and from there to the seabed. Amongst other approaches this involves long term deployments of sediment traps deep in the water column (eg 3000m). A crucial factor is the export flux of material from the upper mixed layer and we have developed a drifting sediment trap which makes direct measurements of this flux, a rate which is notorously difficult to measure. In order the understand the factors that determine the quantity and quality of material mediating this flux, continuous observations are required on a wide range of properties and processes occuring in the upper part of the water column.
I will spend most of my time carrying out and analysing observations of water properties, to provide a context for the biological work on the cruise. In particular I aim to investigate the temperature and saltiness of the water and how turbulent it is.
I am soon to be starting a PhD at NOC and on this cruise I will be looking at particle flux using a marine snow catcher. This is basically a really big bottle to catch the sinking and suspended particles. The particles are collected and measurements made to try and determine how the composition and abundance of particles changes with depth in the water column.
Hi, I'm Kev.
I'm a mechanical engineer at the National Oceanography Centre and one of my long-term projects over the past few years has involved the design and development of free-drifting, neutrally buoyant sediment traps that we call Pelagra. We have six Pelagra sediment traps on board with us and I will be responsible for the set-up, deployment and technical support for them.
I am a physical oceanographer working on the OSMOSIS project (Ocean Surface Mixing, Ocean Sub-Mesoscale Interaction Study). The OSMOSIS project is concerned with physical processes which deepen and shallow the mixed layer. I work with seagliders, which give us physical and biogeochemical data with high spatial and temporal resolution.
I am a zooplankton ecologist, and mostly interested of the role of copepods in food webs and in biogeochemical cycles. I have a special interest on a small copepod called Microsetella norvegica, an abundant but relatively unknown species, which (likely) colonizes and feeds on sinking particles. During the cruise my plan is to study the effect of Microsetella and other copepods on vertical flux, in practice by measuring their individual carbon budgets (feeding, respiration, production and egestion) and their vertical distribution and abundance.
I am from Colombia and I’m a POGO fellow. I started my training one month before the cruise at DTU-Aqua (Denmark) with Marja (Koski) and I’ll help her doing experiments with zooplankton during the cruise. Zooplankton describes very small animals (usually less than 4mm) that live in the water column and are not able to swim again ocean currents. Although they are small and we need a microscope to identify and count them, they are very abundant in the oceans and are an important food source for fish larvae. To collect them we use nets of different mesh sizes (e.g. 200, 300 or 500 µm). During the cruise, I’ll do egg production, hatching success, and grazing experiments with Calanus spp., one of the most abundant copepod taxa in the area. The idea is to make a carbon budget for these species and assess how much they are contributing to the downward carbon flux.
My name is Chris Lindemann and I am a PhD student at DTU Aqua in Denmark. My research interest focuses mainly around modelling bio-physical coupling of phytoplankton. To improve parameter value used in modelling approaches, on this cruise I will measure community oxygen dynamics from different depth and different incubation treatments. By doing so, I hope to get a better understanding of respiratory rates in relation to light and other environmental parameters such as turbulence.
I work as a university teacher and researcher at University of Tromsoe in northern Norway. One of my research interests is the vertical distribution of zooplankton, and what causes the formation of horizontal layers of different species. Some species tend to occur together, while others appear to avoid each other. For this study I use an instrument called an “autonomous digital Video Plankton Recorder”, which collects images of particles and simultanoeus information on salinity, temperature and chlorophyll fluorescence. The instrument is lowered into the water column on a wire at a speed of close to 1 m/s, and then takes 20 images per second, each representing about 25 ml of water with plankton and particles.
I am a PhD student at IMS-METU , department of Physical oceanography, Turkey and my work focuses on the modelling of lower trophic levels in a biogeochemical framework. For this particular cruise I am interested in measuring the nitrogen cycle, specifically nitrogen uptake rates of phytoplankton to be used in marine ecosystem models. Further, measurements of atmospheric dry deposition, like dust, particles and metals, are being taken to investigate the flux from the atmosphere into the ocean.
My research focuses on zooplankton ecology and biological oceanography and the effects of zooplankton on particle repackaging and contribution to the biological pump as well as the impacts of climate variation on zooplankton distribution, abundance, and POC flux through the deep-sea.
On the cruise our group will be collecting zooplankton for biomass, grazing impact, and community analyses. Our group will also be incubating zooplankton to determine fecal pellet production rates.
As a Masters student in Marine Biology I'm very excited about the
chance to study the vertical community structure of mesozooplankton.
This should be an interesting chance to further explore research into
anthropogenic contamination which I did during my undergrad degree.
I study the ecology of mesozooplankton and I am a PhD student at the School of Ocean Sciences, Bangor University.
Hi, I'm Zoe. This is my first 'research cruise' and my first time on the RRS James Cook! Currently studying Ocean Science and will be measuring primary productivity and chlorophyll on this cruise, as well as carbon, phosphorus and nitrate! Definitely looking forward to seeing what it's really like at sea!
I am a PhD student at NOCS, Southampton. My research is related to detecting climate change signals in marine primary productivity. On this cruise I will be analyzing water samples for chlorophyll estimation. I will also be helping in measurement of Particulate Inorganic Carbon (PIC) and Particulate Organic Carbon (POC).
During this cruise I will focus on the underwater blizzard of marine snow. These blizzards are essentially the processes which enable the oceans to take up and store carbon dioxide from the atmosphere. It is therefore important to understand both what makes the marine snow fall and what prevents them from falling. To investigate this we need to catch the marine snow flakes and bring them to the laboratories on the James Cook. To do this we will use snow collectors which are deployed for several days (so called sediment traps) and collectors which are immediately "catching" a large volume of water with its snow flakes (Snow Catcher). In the laboratories, we measure how fast the different types of snow sink and at what rates they are degraded. this indicates the amount of marine snow which reaches the seafloor and thereby remove the carbon dioxide fixed within it from the atmosphere.
I am a Post-Doc at IMS-METU working on modelling biogeocehmical dynamics in the North Atlantic. On this cruise however I will be measuring nitrification rates of heterotrophic bacteria in the euphotic zone, that is the upper part of the ocean which is still penetrated by light. Furthermore I will preform experiment looking at the impact of ocean acidification on the nitrogen cycle for the integration into modelling frameworks.
I am a first year PhD student in the National Oceanography Centre, Southampton, working with biochemical data from autonomous underwater Seagliders.
I am a research technician at NOC where my work involves looking after the day to day running of our groups chemistry labs and running the various chemical analysers that our group has. On this cruise I will be focusing on the analysis of inorganic and organic nutrients and their relation to the marine living environment.
I'm an MSci Oceanography student in Southampton and I'm joining the cruise to help measure nutrient and oxygen concentrations.
I have recently finished my Masters in Oceanography at Southampton and in my final year I focused on the large scale transports of dissolved inorganic and organic nutrients in the North Atlantic. I have previous experience at sea and I have joined this cruise to provide assistance in the collection of data.
My research interest focuses around lipids chemistry. In particular on this cruise I am investigating the lipid composition of particulated organic matter, living and non-living. Because lipids are more stable than other major biogeochemical components, they can be used to trace the degradation of organic matter and its preservation potential. Lipids also can serves as an indicator for environmental conditions, like nutrient availability for plankton growth.
I am just about to finish my undergraduate degree in oceanography. I have focussed on biogeochemistry and in particular iron during my final year and this will be my first offshore cruise.
