Microbial eukaryotes (or protists) in marine ecosystems are a link between primary producers and all higher trophic levels, and the rate at which heterotrophic protistan grazers consume microbial prey is a key mechanism for carbon transport and recycling in microbial food webs. At deep-sea hydrothermal vents, chemosynthetic bacteria and archaea form the base of a food web that functions in the absence of sunlight, but the role of protistan grazers in these highly productive ecosystems is largely unexplored. Here, we pair grazing experiments with a molecular survey to quantify protistan grazing and to characterize the composition of vent-associated protists in low-temperature diffuse venting fluids from Gorda Ridge in the northeast Pacific Ocean. Results reveal protists exert higher predation pressure at vents compared to the surrounding deep seawater environment and may account for consuming 28 to 62% of the daily stock of prokaryotic biomass within discharging hydrothermal vent fluids. The vent-associated protistan community was more species rich relative to the background deep sea, and patterns in the distribution and co-occurrence of vent microbes provide additional insights into potential predator–prey interactions. Ciliates, followed by dinoflagellates, Syndiniales, rhizaria, and stramenopiles, dominated the vent protistan community and included bacterivorous species, species known to host symbionts, and parasites. Our findings provide an estimate of protistan grazing pressure within hydrothermal vent food webs, highlighting the important role that diverse protistan communities play in deep-sea carbon cycling.

ECORD Summer School: Downhole Logging for IODP Science (Online), September 13-17, 2021 - NEW!
The ECORD Summer School this year will combine in-person sessions with asynchronous teaching, group activities, and exercises from the International Ocean Discovery Program (IODP) world. The Summer School introduces the interpretation and applications of downhole logs and physical property data primarily from the IODP. The School explores the relevance and unique insights of these data for a range of fields, including paleoclimatology, sedimentology, hydrogeology, and broader geological and ecological processes such as sediment provenance and water column productivity. The Summer School is open to applicants from all career stages and geoscience backgrounds. However, the course is tailored for individuals who are early in their career and/or would like to introduce and make use of more physical properties data in their research and/or; would like to get more involved in IODP in some capacity, either through accessing and using data or sailing on an IODP research expedition. Applications due August 2, 2021.

UNOLS: Council Positions Call for Nominations - NEW!
The University-National Oceanographic Laboratory System (UNOLS) is an organization of academic oceanographic institutions working in cooperation with agencies of the U.S. Federal Government to ensure broad access to modern, well-operated, state-of-the-art research vessels, submersibles, and other facilities required to support a healthy and vigorous research and education program in the ocean sciences. Currently, UNOLS is actively engaged in academic research fleet modernization efforts, COVID-19 response efforts and getting science back to sea, outreach initiatives for early career scientists and underrepresented communities, and efforts to promote a positive work environment at sea. Individuals who wish to contribute to these and other UNOLS efforts are needed to fill three UNOLS Council seats.  The UNOLS Council members represent and act on behalf of the UNOLS membership as the operating and governing body of UNOLS. Nominations are due by August 12, 2021.

CUNY Queens College: Lecturer in the School of Earth and Environmental Sciences
Applications will be reviewed as received until July 20, 2021.

NSF OCE: Marine Geology and Geophysics Program Director (Rotator)
The deadline for applications is August 2, 2021.

UNIL: Postdoctoral Researcher in Microbial Geochemistry - NEW!
We invite applications for a 2-year postdoctoral position in the Microbiogeochemistry Lab at the Institute of Earth Surface Dynamics (IDYST) at the University of Lausanne. The newly launched research group headed by Prof. Berg specializes in the application of interdisciplinary approaches - borrowing methods from the fields of biology, geology and chemistry - to solve complex environmental questions related to biogeochemical cycling. Steady-state concentrations of certain redox species may arise from the balance between continuous oxidation and reduction reactions, and although concentration changes cannot be measured, their rapid turnover can play a key role in the environment and sustain highly active and diverse microbial communities. This project will focus on hidden or "cryptic" microbial processes and their impact on Fe, S, and O cycling on ancient earth to modern-day ecosystems. The deadline for applications is August 20, 2021.
