US GO-SHIP seeking co-chief scientist for 2023 I05 (32S)

We are looking for early career scientists and/or sea-going technicians with experience in physical or chemical oceanography (hydrography) who would be interested in participating as co-Chief Scientist on the decadal re-occupation of the U.S. GO-SHIP hydrographic long-line known as I05 (32°S in the Indian Ocean). This cruise ~8 weeks long (mid-July to mid-September 2023).


  • We will be sailing on the R/V Revelle (
  • Chief Scientist – Brendan Carter
  • 55 Days at Sea (Fremantle, Australia to Cape Town, South Africa)


  • Pre-cruise: Assist Chief Scientist with pre-cruise planning as needed. Attend pre-cruise meeting if feasible. Assisting with the selection of the CTD-watch students.
  • At sea: Co-Chief will be scientist-in-charge of one 12-hour watch, opposite the Chief Scientist with the following responsibilities: ensuring the CTD watch runs the CTD console and completes routine forms and tasks for each station; mentoring students assigned to the watch; deciding sampling levels for each parameter in accordance with the chief scientist; organizing the CTD watch and assisting with water sampling (directing operations (sample cop) and/or obtaining water parameter samples (e.g. salinity, nutrients); and assisting in at-sea data reviews, reports, and documentation.
  • Post-cruise: Assist the Chief Scientist with cruise report finalization and review of data, quality codes, and documentation.

SUPPORT: Salary support for academic co-Chief Scientists will be negotiated, and is typically supplied via sub-awards from UCSD/SIO to the participant’s institution. It typically covers time at-sea, in port, on travel, and about two weeks of salaried time for preparation. Travel will be paid by UCSD/SIO.

WHO CAN APPLY: The co-Chief positions are considered stepping-stones for early career scientists but are also open to higher-level scientists/technicians with graduate degrees or equivalent experience. No at-sea experience is necessary, although it can be a plus. The Chief Scientist will provide training on board. Although preference may be given to those with ongoing research in the Indian Ocean, all are welcome to apply. If there are multiple qualified applicants for these positions, the Chief Scientist in consultation Principal Investigators will provide recommendations to the U.S. GO-SHIP Executive Council who will approve final selection.

HOW TO APPLY: I05 will provide an excellent opportunity to work at sea and the co-Chief Scientist will have the opportunity to become familiar with and/or extend their knowledge of South Indian oceanography. To join us at-sea for some hard work that will lead to a rewarding experience observing the southern subtropical Indian Ocean first hand, email letters of application to Alison Macdonald ( and Brendan Carter ( Please provide your CV, a brief summary of your research interests and experience and include the name, email address and phone number of a reference.
