Postdoctoral Position – Global Modeling of Oceanic Nanoplastic Distributions at LOPS
Duration: 20 months
Closing date: 15 November 2024
The selected researcher will join the “Ocean and Climate” team at LOPS in Brest (www.umr-lops.fr). LOPS is a joint laboratory between CNRS, Ifremer, the University of Brest and the Institute of Research for Development. The Ocean and Climate team is leader in high resolution modelling as well as international ocean observation programs.
The postdoctoral researcher will work at LOPS, co-supervised by Christophe Maes (LOPS) and Camille Richon (LEMAR), in close collaboration with the partners of the BubblePLAST project (GET, LCE, IGE). The project will involve interactions with researchers in oceanography, marine ecology, chemistry, atmospheric sciences and biogeochemistry. Travel to consortium meetings and conferences is expected.
The ecological and climatic impacts of nanoplastics are a major concern for environmental research and the management of marine ecosystems. As part of the ANR BubblePLAST project, we are seeking a postdoctoral researcher for a 20-month position. The BubblePLAST project aims to understand the mechanisms of nanoplastic exchange between the ocean and the atmosphere. One of the project's key objectives is to study the transport, accumulation, and degradation of nanoplastics in the ocean, with a particular focus on their interaction with marine biogeochemical processes.
The global NEMO/PISCES-PLASTIC model, a coupled ocean-atmosphere-biogeochemistry model which includes a scheme for microplastics distribution, will be used and further developed during this postdoc to simulate the global distribution of nanoplastics in the oceans. This model will help assess the long-term transport and potential accumulation zones of these particles, considering their sources (through the degradation of microplastics) as well as processes of fragmentation, aggregation, and sedimentation. The results of these simulations will contribute to the development of a coupled ocean-atmosphere model to understand and quantify the mechanisms of nanoplastic emission from the ocean surface into the atmosphere.
The postdoctoral researcher will:
- Develop a nanoplastics module within the NEMO/PISCES-PLASTIC model.
- Conduct numerical simulations to model the global distribution of nanoplastics in the oceans.
- Analyze simulation results in collaboration with project members to study accumulation zones,
interactions with marine ecosystems, and biogeochemical processes.
- Compare model results with available observations and suggest areas for improvement.
- Present the results at international conferences and contribute to scientific publications.

Senior Research Associate at UEA
Duration: 18 months
Closing date: 25 November 2024
Details: https://vacancies.uea.ac.uk/vacancies/1290/senior-research-associate-fixed-term-for-18-months--ra2263.html
An exciting opportunity has arisen for a Senior Research Associate to join the School of Environmental Sciences to conduct studies on marine plankton respiration.
In this role, you will work on a project investigating the role of coccolithophores in marine carbon cycling and how this might change in a warmer ocean.
The post is funded by the Natural Environment Research Council (NERC) as part of its BIO-carbon program, which aims to better understand carbon cycling and the biological carbon pump in the North Atlantic.
As Senior Research Associate you will contribute ideas and/or enhancement of techniques or methodologies. You will analyse and interpret data, write up results and present information on research progress and outcomes. You will also have the opportunity to contribute to grant applications and may be involved in the supervision of researchers and teaching of students within the School.
You will have a PhD level research degree in Biological, Microbiological or Chemical Oceanography, equivalent qualification or experience in a relevant research area. You will also have experience of independent research related to the project, have publications in respected journals or equivalent within the field and be able to work in a proactive and results driven manner in a high paced environment. You will also have strong interpersonal and communication skills, with the ability to analyse and interpret data and work effectively as part of a team. Advanced skills in plankton production or respiration directly related to the research project would be advantageous.
This full-time post is available from 13 January 2025 on a fixed term basis for 18 months.
UEA offers a variety of flexible working options and although this role is advertised on a full-time basis, we encourage applications from individuals who would prefer a flexible working pattern including annualised hours, compressed working hours, part time, job share, term-time only and/or hybrid working. Details of preferred hours should be stated in the personal statement and will be discussed further at interview.

Carbon Flux Postdoc at MBARI
Duration: 3 years
Start date: Flexible, though ideally summer or fall 2025, with major fieldwork starting early 2026.
MBARI’s mission is to advance marine science and engineering to understand our changing ocean. Our work focuses on diverse areas of marine and engineering research—from atoms to ecosystems. MBARI is dedicated to the development of innovative instrumentation, systems, and methods supporting scientific research in the oceans. Teams of scientists and engineers are collaborating to build innovative tools to transform what we know about ocean processes and ocean health. Ongoing programs at MBARI span marine robotics, ocean physics, chemistry, geology, biology, and engineering.
The Carbon Flux Ecology group at MBARI is seeking a postdoctoral fellow to join our team. Our work is guided by a pressing need to better observe carbon export via sinking particles in the ocean and to resolve ecological mechanisms that control this process. The postdoctoral fellow will contribute to a multi-institutional, interdisciplinary project funded by the Schmidt Sciences Ocean Biogeochemistry Virtual Institute (OBVI). This project will study the role of mesopelagic animals, and their gut microbiomes, in transforming organic matter as it transits through the mesopelagic. Our team will be responsible for collecting sinking particles and analyzing their molecular genetic contents. We will collaboratively synthesize these observations with data from animal gut contents concurrently collected by other research groups. We will also observe particles in situ using innovative imaging instruments. The ideal candidate will be able to pursue and explore their own research goals within this framework. While the primary focus of this postdoctoral fellowship will be on the OBVI research program, the fellow will also have the opportunity to participate in other research activities performed by the Carbon Flux Ecology group that primarily occur in Monterey Bay, depending on the specific interests of the candidate.
This project involves two research cruises aboard the R/V Falkor too in the South Atlantic Ocean. The ideal candidate would participate in fieldwork, assist with sediment trap deployments, and lead the molecular analyses of sinking particle samples. This position requires an attention to detail and experience in performing sensitive laboratory techniques. Experience with specific molecular techniques (DNA extraction, PCR, metabarcoding) is a plus, but we also value team members with diverse backgrounds and perspectives working in this highly interdisciplinary field who are motivated to add these attributes to their skillset. For that reason, we will also consider candidates without prior experience but who demonstrate capacity for training in our specific protocols.
Required qualifications:
- PhD must be awarded by start date
- Strong problem-solving skills and scientific integrity
- Demonstrated ability to work both independently and as part of collaborative teams
- Demonstrated experience with sensitive laboratory techniques
- Curiosity about ocean biogeochemistry and ecology
Desirable skills and experience:
- Experience with molecular genetic techniques and analyses
- Previous experience performing data analysis using python or R coding languages
- Previous experience in measuring carbon exported by sinking particles
- Previous experience at sea and/or the desire to work at sea for 1 month at a time
Application requirements:
- A cover letter explaining how this opportunity matches your career goals
- Curriculum vitae
- A list of 3 professional references, including name, email address, and phone number
This postdoc fellow will be mentored by Dr. Colleen Durkin and prospective applicants are encouraged to contact her with questions or for additional information about the position (cdurkin@mbari.org).
