Observational Oceanographer

Biography

I am a physical oceanographer working in the Polar Oceans group at the British Antarctic Survey, where I have been since 2004. During this time I have been involved in a variety of projects, mainly involving observations in the ocean, including long-term sustained observations using moored and profiling instrumentation. In addition to analysing and processing data, I enjoy getting involved with the data acquisition. Since 2000, I have participated in 29 scientific cruises, all but two of them to the polar regions.

Please click the tabs above for information about my current and recent research projects.

Employment:

Aug. 2004–present: Oceanographer at British Antarctic Survey, at UKRI band E / NERC band 5 / Senior Scientific Officer level since 2019.
Mar. 2003–Aug. 2004: Data Manager for MOEN (Meridional Overturning Exchanges in the Nordic Seas), a component of the ASOF (Arctic–Subarctic Ocean Fluxes) project, based at the Bjerknes Centre for Climate Research, Univ. of Bergen.
May–June 2001, 2002, and 2004: Field Instructor on the Air/Sea/Ice interaction course at UNIS, performing oceanographic measurements under sea ice in Fram Strait.

Education:

2004–2012: Ph.D. in Oceanography, studying part-time, University of Southampton

Upcoming projects:

POLOMINTS (Polar Ocean Mixing by Internal Tsunamis), Jan. 2025 – Jan. 2030. More information coming soon!

Current projects:

KANG-GLAC (Assessing ocean-forced, marine-terminating glacier change in Greenland during climatic warm periods and its impact on marine productivity), Apr. 2024 – Dec. 2027. This NERC grant addressing the highlight topic of marine-terminating glaciers, will be looking at the ocean circulation in and around Kangerlussuaq Fjord in East Greenland, linking the present conditions (both physical and biological) to geological records of ice sheet retreat. The first cruise for this project took place on RRS Sir David Attenborough in July-August 2024.
OCEAN:ICE (Ocean-Cryosphere Exchanges in ANtarctica: Impacts on Climate and the Earth System), Nov. 2022 – Oct. 2026. This Horizon Europe/UKRI-funded programme aims to study the interactions between the ice and sea in the Southern Ocean. As part of this project, we will be deploying moored instrumentation in South Sandwich Trench to evaluate the exports from this rarely sampled deep export pathway from the Weddell Sea.
BIOPOLE (Biogeochemical processes and ecosystem functioning in changing polar systems and their global impacts), 2022-2027, is a five-year NERC multi-centre programme investigating changes in the biochemical and physical systems in the Antarctic and Arctic. My involvement is with physical observations using moorings, autonomous vehicles, and oxygen isotope sampling.
Orkney Passage, 2005-present: I have designed, and regularly deploy and service oceanographic moorings in Orkney Passage, as part of BAS’s ongoing Long-term Monitoring and Survey (LTMS) activities in this area, and part of the ORCHESTRA/ENCORE project 2016-2022 and BIOPOLE 2022-2027.
A23, 2013-present: I am currently coordinating BAS’s annual repeats of the northern part of the WOCE A23 hydrographic section from the Weddell Sea to South Georgia. This section has been occupied a total of 15 times since 1995, with BAS cruises taking place most years since 2012. It was incorporated into the ORCHESTRA/ENCORE project in 2016-2022 and BIOPOLE in 2022-2027. The next repeat will hopefully take place around Feb. 2025.
SO-CHIC (Southern Ocean Carbon and Heat Impact on Climate), Nov. 2019 – Oct. 2024. The overall objective of SO-CHIC is to understand and quantify variability of heat and carbon budgets in the Southern Ocean through an investigation of the key processes controlling exchanges between the atmosphere, ocean and sea ice using a combination of observational and modelling approaches. More specifically, I will be working with colleagues from other European and partner nations to draw together our observations from around the Weddell Sea.

Previous projects:

SO-ICE (Southern Ocean – Ice Shelf Interaction), Sep. 2021 – Aug. 2023, is an ESA collaborative research project linking the ESA Polar+ Ice Shelves and 4D Antarctica projects with SO-CHIC, in order to improve understanding of the processes controlling ice-ocean interactions in Antarctica.
ORCHESTRA (Ocean Regulation of Climate through Heat and Carbon Sequestration and Transports), 2016-2021, and its one-year extension ENCORE (‘Encore is the National Capability ORchestra Extension’), 2021-2022. This large NERC cross-centre project studied heat and carbon fluxes in the Southern Ocean. It combined sustained observations in Orkney Passage and along the A23 section with sections across Drake Passage and across the South Atlantic, and remote sensing and computer modelling. My involvement was mainly on the observational side.
DynOPO (Dynamics of the Orkney Passage Outflow), 2014-2018. This project aims to study the processes controlling and affecting the properties and strength of the outflow of Weddell Sea Deep Water through Orkney Passage, a deep channel in the South Scotia Ridge.
iSTAR (NERC’s Ice Sheet Stability programme), 2010-2018. My role has been to coordinate the design, procurement, and deployment of oceanographic moorings in the Amundsen Sea, as well as assisting with project management/coordination and the iSTAR website.
Operation Iceberg, 2012. I participated in the filming of the second episode of BBC documentary Operation Iceberg, looking at the breakup of Petermann Ice Island B-1 in Baffin Bay. While much of the work didn’t go to plan (largely because of bad weather and a glut of polar bears), we did gain some very interesting insights into how icebergs break up.
Arctic Synoptic Basinwide Oceanography (ASBO), 2007-2010. I investigated the freshwater composition and pathways in the Laptev and East Siberian Seas using stable oxygen isotopes (δ18O) and dissolved barium samples.
Oceanographic conditions and processes beneath Ronne Ice Shelf (OPRIS; part of the Autosub Under Ice programme), 2004-2007. I studied the circulation and melt beneath Fimbul Ice Shelf, Antarctica, using data from the Autosub-2 AUV and other nearby measurements, as well as using an ice shelf-enabled Regional Circulation Model, POLAIR. This work formed the basis for my PhD thesis.
