Postdoctoral Position in Biogeochemical Oceanography

A postdoctoral position is available at the Bermuda Institute of Ocean Sciences (BIOS) to work on a project titled “Nitrous oxide reduction in oxygen minimum zones: an understudied but critical loss term in ocean greenhouse gas cycling”. This field-based project will incorporate 15-N tracer measurements of nitrous oxide production and consumption, as well as natural abundance isotope and molecular genetic measurements, to better understand the magnitude of nitrous oxide production and consumption as marine dissolved oxygen concentrations transition from oxic-hypoxic-anoxic conditions. The successful applicant will primarily work with Principal Investigator Dr. Damian Grundle (BIOS) and will contribute to overall project management, conduct international travel for the purpose of participating in field sampling and attending conferences, conduct laboratory measurements, and contribute to data analysis, manuscript writing and preparation of proposals. Opportunities also exist to participate in molecular genetic sampling and analysis with co-PI Dr. Frank Stewart. Drs. Grundle and Stewart will be committed to maximizing the research experience of the postdoc and to ensuring they foster the professional skills required for long-term career success.

Applicants should have a Ph.D. in marine science or similar field, with preference given to those with a background in aquatic biogeochemistry and nitrogen cycling.

The duration of the postdoc is for two years with the potential for extension dependent on performance and available funding. The preferred start date is asap.

Interested applicants should contact Dr. Damian Grundle ( with a cover letter outlining their motivation for applying for this position and relevant experience, and a CV including contact information of three references.

Oceanography Research Technician

The Bermuda Institute of Ocean Sciences (BIOS) is seeking a motivated oceanography research technician to work on the U.S. National Science Foundation funded time-series programs; Bermuda Atlantic Time-series Study (BATS) and Hydrostation ‘S’. These BIOS hosted projects are focused on understanding the processes that influence the variability of the physics and biogeochemistry of the Sargasso Sea and ultimately how these processes interact to regulate the carbon cycle. Both programs have a strong field component requiring a dedicated team of scientists to perform the at-sea data and sample collection, and subsequent shore-side data processing and sample analyses. For this current position we are looking for an individual with at least a B.Sc., though Masters preferable in oceanography/marine science or closely related subject with a focus on chemical or biological oceanography.

Demonstrated experience of analytical work in a laboratory environment using sound practices with a range of chemical instrumentation and the ability to work synergistically in a multidiscipline team of oceanographers are essential requirements for this position. A proven sea going capability and specific experience (one or more years) of elemental analyzers are a distinct advantage. The expected duties are:

  • Perform CHN elemental analyses for POC&N and sediment trap samples
  • Maintain all instrumentation associated with POC&N and sediment trap methods
  • Regular participation on the time-series cruises (~5 to 7 days/month)
  • Perform dissolved oxygen analyses using chemical titration systems
  • Perform bacteria production assays using 3H uptake methods
  • Produce reports on data status in consultation with the P.I.’s
  • Interact with PI’s and other scientists on data synthesis
  • Assist where required to maintain overall project objectives

The position will initially be for 1-year with continuation depending on job performance and starting salary will be in the range of $38,000 to $47,000 commensurate with experience and qualifications. Given the restrictions on sponsored dependents residing in Bermuda set by the Department of Immigration, all applicants are recommended to review Section 5 of the Work Permit Policy. Review of applications will start immediately with the effective starting date of June, 2019, subject to Immigration approval. For further information on this position or to make a formal application (cover letter, CV and contact information of two references) please contact Dr. Rod Johnson ( and state “BATS CHN Research Technician-2021” in subject line for all correspondence relating to this position.

Assistant Scientist in Oceanography (Physical Oceanography/Biogeochemical System Approaches)

The Bermuda Institute of Ocean Sciences (BIOS), an independent U.S. not-for-profit marine research institution based in Bermuda, is seeking an early career candidate for an Assistant Scientist position. We seek applications from current postdoctoral scholars/fellows or recent PhD graduates in oceanography or closely related subjects. We welcome a broad range of potential topics for study, including physical oceanography process studies at all scales, biogeochemical research with practical experimentation, and system modeling with strong integration of data. We seek a candidate who will take advantage of the opportunities and facilities offered at BIOS which include bi-weekly access to the deep ocean, repeat measurements and long-term monitoring of ocean properties, integration of glider observations with traditional ship-based measurements and laboratory access for chemical and biological measurements and experimentation.  The successful candidate will oversee a fleet of autonomous underwater gliders equipped with sensors systems for biogeochemical and physical oceanographic research.

Experience with proposal writing targeted at the US federal agencies (e.g., National Science Foundation, NOAA, NASA) will be an asset. The recipient will receive full salary support for a two-year period, with possibility of extension depending on performance success (e.g., grant funding with the US federal agencies) with the primary emphasis on supporting the individual’s research promise in his/her chosen area of research. Support is also available for startup equipment, relocation, travel to scientific meetings, equipment and supplies.

Scientific activities at BIOS are wide-ranging, collaborative and include oceanographic and atmospheric time-series studies and a broad range of coral reef research. Major long-term initiatives of BIOS include the following: (1) Bermuda Atlantic Time-series Study (BATS); (2) Hydrostation S program; (3) the Oceanic Flux Program; (4) BIOS-SCOPE; and, (5) the M/V Oleander project. The institution supports the operations of the RV Atlantic Explorer, a UNOLS research vessel making 20+ short cruises to the time series stations each year. BIOS also operates three autonomous underwater gliders with near-continuous, year-round occupation at the time series stations (the Mid-Atlantic Glider Initiative and Collaboration (MAGIC). Additional information on BIOS can be found at

Although primarily a research position, opportunities exist for teaching and mentoring at the undergraduate graduate student level (  A Ph.D. or equivalent experience in an appropriate discipline is required.

Qualified candidates should submit their application to include: a cover letter, a statement of research interests, and a curriculum vitae including names of references to: The HR Manager, BIOS, 17 Biological Station, St. Georges, GE01, Bermuda; The position will remain open until filled.
