Postdoctoral research assistant in biogeochemistry of calcifying nannoplankton

University of Oxford – Earth Sciences

Earth Sciences, South Parks Road, Oxford

Location: Oxford

Salary: £32,817 – £36,914 p.a, Grade 7

Hours: Full Time

Contract Type: Fixed-Term/Contract

Placed On: 6th May 2021

Closes: 25th June 2021

Job Ref: 150797



Calcifying phytoplankton, such as coccolithophores, are a fundamental component of the marine carbon cycle. Yet, we have little understanding how changing climate affects calcification and how it is going to evolve under the environmental pressure imposed by global warming and ocean acidification. Currently there is little mechanistic understanding of how energy and carbon flow between photosynthesis and calcification in coccolithophores, and how this dynamic coupling is affected by resource limitation and environmental stress. Our knowledge gap on the environmental sensitivity of the coupling between photosynthesis and calcification means that we still do not know whether coccolithophore calcification increases or decreases in response to ocean acidification, despite 20 years of research.

PUCCA (Photosynthetic Underpinnings of Coccolithophore Calcification) will take advantage of advances in cutting-edge techniques that document and mechanistically interrogate the sensitivity of coccolithophore calcification rates to the environment. A new physiological model of carbon isotopic fractionation in coccolithophores allows the reconstruction of species-specific calcification rates from the sedimentary record. Additionally, methods have advanced that can extract and characterise biochemical molecules from fossils over a hundred million years old which will allow the interrogation of controlling environmental parameters.

The successful candidate will be responsible for identifying which environmental parameter(s) drive the highest coccolithophore calcification rates during the Cenozoic, and across the modern ocean. As approaches, they will use ocean sediments as a recorder of coccolithophore stable isotope vital effects, extracted polysaccharides and other organic molecules, as a measure of the physiological sensitivity of calcification to different environmental regimes. They will also document how the sensitivity of calcification rates to environmental parameters is influenced by cellular resource allocation strategies using culture experiments of a range of strains of Emiliania huxleyi subjected to environmental limitation. These experiments will provide the foundation for calibrating organic molecules for the environmental impact on their structure and composition.

The successful candidate will hold, or be close to completion of, a relevant PhD. They will also have experience in stable isotope palaeoceanography and/or nannofossil palaeontology. Familiarity/prior experience with physiology (ideally of coccolithophores), and an understanding of organic/biochemistry, and biomineralisation will be an advantage. They will have the ability to manage their own academic research and associated activities and have excellent communication skills, including the ability to write for publication and present research proposals and results.

For further details of the responsibilities/duties, please see job description. This post is fixed term for 3 years from 06 September 2021 (or as soon as possible after). Candidates should apply online by midday on Friday 25 June 2021. Interviews will be held in mid-July 2021.

Early career (PhD) positions for research into ocean alkalization and CO2 uptake

Join a diverse team studying how the addition of alkalinity, produced during production of clean hydrogen fuel, can enhance the ocean’s uptake of CO2.

We are recruiting a team of early career researchers (including up to 4 PhD positions) with interest in environmental chemistry (#1 and #4 in figure), aquatic biology (#2-4), and marine physics (#3) to work within a unique, multidisciplinary team. The team will investigate the efficacy and impact of adding alkalinity to coastal seawater in order to increase the ocean’s capacity for removing CO2 from the atmosphere. The research will contribute to development of Planetary Hydrogen’s innovative co-production process, which aims to produce H2 as a clean fuel while decarbonizing our economy and contributing to Canada’s greenhouse gas reduction commitments under the Paris Agreement. For more details, please visit the project website ( or contact the entire project team at:


  • Douglas Wallace
  • Hugh MacIntyre
  • Ruth Musgrave
  • Jeff Clements
  • Ramon Filgueira

Project Description and Opportunities

Hydroxide ion, generated as a byproduct of a novel process of hydrogen generation, can be used to increase the ocean’s ability to take up and store atmospheric CO2 in the form of dissolved bicarbonate. This alkalinity addition mimics the natural geochemical weathering reactions that have created the ocean’s massive reservoir of bicarbonate and carbonate ions, and can potentially benefit organisms that are vulnerable to ocean acidification, including commercially important shellfish.

Application for analysis of ocean acidification and multiple stressor extremes

The Atmospheric and Oceanic Sciences Program at Princeton University in cooperation with NOAA’s Geophysical Fluid Dynamics Laboratory (GFDL) seeks a postdoctoral or more senior scientist to identify oceanic areas subject to extremes in individual and multiple biogeochemical stressors (e.g. ocean acidification, temperature, ocean deoxygenation), and evaluate against site-specific observations to help inform requirements for future instrument deployment, as well as the development of sustainable management strategies. The incumbent will leverage GFDL’s existing 1/2 degree fully-coupled Earth System Model (ESM4.1) and an experimental suite including historical, climate change, mitigation, and idealized scenarios to a) conduct time slice model simulations to generate required model output, b) assess global and regional trends and variability of ocean stressor extremes, c) implement a coastal residence time tracer, and d) assess coastal residence times. The incumbent will also conduct place-based analyses of multiple stressor extremes through compiling and assessing NOAA Ocean Acidification Program (OAP) buoy observations for comparison to model data. Lastly, the incumbent will develop a compilation of co-located marine stressors and associated ecosystem metrics for US territorial waters and Marine Protected Areas. Personnel will join an active group at Princeton and GFDL studying the connections between biogeochemistry, ecosystems, and climate (

This is a one-year appointment, renewable each year up to three years pending satisfactory performance and funding. This position is based at GFDL in Princeton, New Jersey. Complete applications, including a cover letter, CV, publication list, a one to two-page statement of research interests and names of at least 3 references in order to solicit letters of recommendation, should be submitted online by May 1, 2021 11:59 p.m. EST for full consideration, though evaluation will be ongoing.

Essential Qualifications: PhD is required. Candidates with quantitative, interdisciplinary knowledge from subsets of fields including climate dynamics, ocean and coastal biogeochemistry, marine ecosystem dynamics, and fisheries science and management are particularly encouraged to apply. Experience analyzing large data sets and/or model output is also critical, as is model development experience for those positions.
