Sheri White – Mooring lead (Woods Hole Oceanographic Institute)
The Ocean Observatories Initiative (OOI) is a US National Science Foundation (NSF) funding program to create a permanent long-term presence in the ocean for scientific measurements. OOI consists of a number of arrays of mooring and vehicles – a regional Cabled Array off of the US West Coast, 2 Coastal Arrays off of the US East and West Coasts, and 3 Global Arrays. The Global Arrays are located in the Irminger Sea, south of Greenland, in the Gulf of Alaska, and in the Southern Ocean west of Chile. All of the data collected is made freely available to the public http://oceanobservatories.org/.
The OOI Southern Ocean Array, consisting of 1 Surface Mooring, 3 Subsurface Mooring, and autonomous gliders, was first deployed in March 2015. It was redeployed in December 2015, and November 2016. In 2017, the NSF elected to discontinue operations at the Southern Ocean Array site. However, the recovery cruise in November 2017 was unable to recover all of the moorings due to weather conditions.

On the DY096 CUSTARD Cruise, we have deployed a new Surface Mooring at the Array, integrated with 2 lab-on-a-chip sensors (for nitrate and silicate) developed at the National Oceanography Centre in Southampton. This mooring will collect measurements for a year until we return in January 2020 to recover it.
The OOI Southern Ocean Array location is one characterized by strong air-sea interaction and wintertime water mass formation. It is thus at a location important to understanding the large-scale global thermohaline circulation. It is also an exceptionally data sparse region historically, lacking observations of the surface meteorology, air-sea fluxes, variability of the water column physics, chemistry, and biology.

Steve Caldwell-Surface Mooring Lead, Woods Hole Oceanographic Institute
My name is Steve Caldwell from Woods Hole Oceanographic Institution. I am the Surface mooring lead for OOI (Ocean Observatories Initiative) on this cruise. My role is to ensure the proper operation of the surface mooring. That includes such items as: all CPU’s are operating, all telemetry is operating and calling back to land so that we can provide real time data, all meteorological instrumentation is operating and providing correct readings. I am also in charge of all electrical and mechanical components on the mooring, from the computers that control the instruments and mooring power consumption, to the clamps that retain the instruments, to the proper operation of the IMM wire.

I am super stoked about being able to come back to the Southern Ocean and put the mooring back in. This is a super interesting spot for science and to be a part of the engineering aspect of this project is honestly an honor. Being able to work with the other groups such as yours makes it even more exciting, certainly the ability hear what other science communities think of our program and how much that appears to mean to them gives more fuel to my fire. I personally really appreciate the presentations on CUSTARD’s work that were shared with us the other day. You guys are doing some really cool stuff and it’s great to be a part of it.
Alan Wright – PhD Student (National Oceanography Centre)
On the 28th November 1520 Ferdinand Magellan first passed through the waters below South America, that now bear his name. By some lucky quirk of fate, RRS Discovery was sailing through the Magellan Strait exactly 498 years later.
Magellan was so low on rations that his crew were eating leather by the time he entered the strait. However life on the Discovery could not be more different. At least three fantastic meals a day, each meal consisting of multiple courses keep the scientists and support crew energised and motivated.

Magellan named the Ocean he found to the west of the straits ‘pacific’, meaning peaceful or tranquil, however the Discovery found a different ‘pacific’ …the boat started rolling for the first time and some people new to the ocean paid traditional homage to the sea gods.
Luckily we are still in Chilean national waters and had no real duties to perform. Hopefully all sea legs will have been found by tomorrow.
Eleanor Haigh – Masters Student (University of Southampton)
And we’re off! Discovery set sail for 55oS 90oW at 6am today, with the orange glint of sunrise still cast over Punta Arenas we headed into the Magellan Strait. Our passage here has been lined with snow-capped mountains, blue skies, and a handful of marine mammals, and with a lot of set up already completed many of us were able to enjoy some time taking in the spectacular views. As one of the less experienced members of scientific crew on board, I’ve been warned that this beautiful route is quite an exception, and that I shouldn’t expect the calm waters and warming sunshine to continue for much longer as we head into the Pacific. For now it’s safe to say the obsessive screwing, duct taping, and zip-tying of equipment to our lab benches, which we undertook in the past few days, seems a little excessive, but I have no doubt it will become necessary later in the cruise once the weather picks up.

The next few weeks, for me at least, will be a huge learning curve, as this is my first scientific cruise out to the open ocean. I’ll be working with the team responsible for taking measurements for the calibration of the mooring sensors, and also conducting small scale experiments to contribute towards my dissertation, which so far has been focussed on data from the past four years of the mooring series. Witnessing the immense amount of effort that goes into deploying the mooring and collecting said data has been amazing. From the lead scientists, to the ships cook, or the engineers, to the captain, sitting at my desk in Southampton, working through measurements the mooring has made, I would have never imagined such a busy operation happening every year. With high hopes of initial scientific work starting in a few days, I can’t wait to be a part of it!
Adrian Martin – Principle Scientist for RoSES
It seems like it’s been a long time coming, but we’re finally in Punta Arenas and just a couple of days off sailing, to begin the year-long study of how marine life in the Southern Ocean helps the ocean take up and store carbon dioxide from the atmosphere. Today the last equipment came on board, including the huge buoy and mooring that we will be deploying at 55°S 90°W. Between now and Wednesday we’ll be setting up labs and equipment, making sure they are secure against what the weather might send our way. All the team are now on RRS Discovery, and hopefully you’ll be getting their individual perspectives over the next couple of weeks.

As Principle Scientist my main job at present is not to get in the way, while the specialists get everything in order; filter rigs, oxygen analysis equipment, incubators and gliders to name but a few. Then on Wednesday, we’re due to be off, heading west along Magellan Strait into the Pacific, then southwest into the Southern Ocean, keeping fingers-crossed for the following two days, in the hope that when we finally arrive at our study site the weather lets us get cracking from the off.
Senior Research Associate in Ocean Biogeochemistry (Ref: RA1564) University of East Anglia: Faculty of Science – School of Environmental Sciences – closing date 8 January 2018 (£33,199 – £39,609 per annum, pro rata)
Applications are invited for the post of Senior Research Associate (SRA) to undertake research on the ocean carbon sink and downward carbon transport in sub-polar waters of the Southern Ocean. The SRA will work with Dorothee Bakker on the consortium project CUSTARD (Carbon Uptake and Seasonal Traits of Antarctic Remineralisation Depth, https://roses.ac.uk/custard/, 2018-2022). CUSTARD is part of the National Environment Research Council (NERC) RoSES (Role of the Southern Ocean in the Earth System, https://roses.ac.uk/) research programme.
The Southern Ocean south of 35°S takes up about 40% of the carbon dioxide (CO2 ) emitted by human activity. Much of this uptake occurs north of the Polar Front, in the upper limb of the Southern Ocean overturning circulation. The CUSTARD project aims to quantify the impact of nutrient and iron availability on phytoplankton carbon uptake in these sub-polar waters and the transport of carbon to depth away from atmospheric contact on climatically important timescales, using a combination of numerical and observational (shipboard and autonomous) techniques.
The SRA will participate in the planning and delivery of carbonate system measurements for the full water column on the CUSTARD research cruise (November 2019 to January 2020) and the CUSTARD mooring recovery cruise (January 2020). The SRA will combine these observations with year-round sensor data from the mooring and autonomous robotic gliders and will assist with calibration of sensors on the mooring. The SRA will quantify seasonal CO2 air-sea fluxes and the contribution of the solubility, carbonate and soft tissue carbon pumps to seasonal carbon dynamics and downward carbon transport. The SRA will publish the scientific results in international peer reviewed journals.
The research will be based within the Centre for Ocean and Atmospheric Sciences (COAS) at UEA. It will be carried out in collaboration with CUSTARD scientists and project partners, and where appropriate with other RoSES scientists. The SRA will be expected to participate in the CUSTARD research cruise and the mooring recovery cruise in the remote Southern Ocean, subject to a medical and sea survival training.
You will have a minimum of a PhD in biogeochemical oceanography, environmental, chemistry, chemistry (or equivalent independent research experience) and a scientific publication record showing evidence of international quality. The SRA should have excellent oral and written communication skills, with experience of presenting results at conferences and be able to fulfil all essential elements of the person specification.

We are seeking a talented, strongly numerate scientist to deliver high-impact science as part of a world-leading team focused on the role of marine life in the global carbon cycle. The nature of the work is multi-disciplinary and so we encourage applications not just from marine biogeochemical modellers but also from those in other areas of science who are numerically adept and looking to move into an exciting and important area of environmental research.
The role is based within the Ocean Biogeochemistry and Ecosystems (OBE) team at NOC, one of the world’s leading marine biogeochemistry groups. In particular, OBE has made major contributions to our understanding of the ocean’s Biological Carbon Pump (BCP), the process by which marine life can sequester CO2 away from the atmosphere.
This post will be part of the multi-disciplinary and multi-centre teams for three projects. Its important role in all three is to translate new perspectives on key processes arising from cutting-edge observations into model representations, in order to understand and to explore the global and future consequences. For example, the post will use new observations from the Southern Ocean to explore how nutrient limitation may control how much CO2 is trapped in the global ocean and for how long. To do so the post will make use of a novel means of running global biogeochemical models both faster and more flexibly than conventional approaches.
The role also involves interaction with the UK Earth System Model group: the NEMO physical circulation and MEDUS Biogeochemical model, which will form part of the UK Earth System Model used for future IPCC runs, may be used in this role.
The three large multi-disciplinary projects to which this post will contribute are all led by OBE and are focused on the BCP.
COMICS – (http://www.comics.ac.uk/) is investigating the influence of temperature, oxygen and community structure on the BCP.
GOCART – (https://projects.noc.ac.uk/gocart/) is using gliders to examine daily to seasonal variability in the BCP and its consequences.
CUSTARD – (https://roses.ac.uk/custard/) is part of the NERC Role of the Southern Ocean in the Earth System (RoSES) programme and examines how seasonal changes in surface biogeochemistry and plankton community in the remote Southern Ocean influences the BCP and nutrient cycles globally.
How to apply: All internal and external applications are handled by the UK Shared Business Services Ltd (UK SBS).
