Synthesizing Multifaceted Data in Chemical Oceanography

July 23-28, 2017, Colby-Sawyer College, New London, NH

Chair: Karen Casciotti

Vice Chair: Mak Saito

Chemical Oceanography is a multidisciplinary science that integrates research across elements, environments, and platforms on a variety of space and time scales using a multitude of approaches. Themes highlighting the fundamentally interdisciplinary nature of the field have remained at the heart of the GRC in Chemical Oceanography for almost 50 years. The meeting in 2017 will advance these themes and highlight synthesis of multifaceted data in Chemical Oceanography. Highlights will include new methods of data collection, visualization, analysis, and modeling that allow novel insights and connections to be made in all phases of interdisciplinary work. Synthesizing data on multiple elements, with different chemical behaviors and controls allows us to understand key processes that the control the distributions of elements in seawater and marine sediments, as well as to understand how shifts in those distributions may reflect changes at the processes level. New advances in integration of a wide array of measurements on a variety of space and time scales allow scaling from detailed regional studies to global processes in the past, present, and future ocean and create an integrative understanding of Chemical Oceanography whose whole is greater than the sum of its parts.

The biennial GRC in Chemical Oceanography seeks to spur discussion and synthesis of ideas at the leading edge of research within Chemical Oceanography, with an emphasis on presentation of new, unpublished data, interpretations, and ideas in a strictly ‘off the record’ format. All attendees are encouraged to present a poster on their work.

New this year, we will offer a ‘Power Hour’ on Monday afternoon. This is an opportunity for attendees to get together in an informal setting to discuss the challenges facing women in science, and to address those challenges through mentoring and open discussion. This discussion is open to all attendees. We are looking for volunteers to help moderate the discussion. If you are interested, please contact the GRC Chair (

Please note that the GRC offers partial support for faculty from predominantly undergraduate institutions (PUI), researchers from developing nations (through the Carl Storm International Diversity Fellowship), and underrepresented minority participants who are US citizens or permanent residents and are attending a GRC or GRS for the first time through the Carl Storm Underrepresented Minority Fellowship Program. We encourage applicants who are eligible to contact the GRC Chair ( for more information.


How Chemistry Gives Insight into Ocean Processes

July 22-23, 2017, Colby-Sawyer College, New London, NH

Chairs: Claire Till and Hilary Palevsky

The Gordon Research Seminar (GRS) on Chemical Oceanography, held in the two days immediately preceding the GRC, is a unique forum for graduate students, postdocs, and other scientists with comparable levels of experience and education to present and exchange new data and cutting-edge ideas. The GRS aims to allow these early career scientists to present and discuss their research with their peers in a GRC-type atmosphere, in the absence of the more senior cadre. The focus of this meeting is chemical tracers providing insight into oceanic processes. Tracers are widely used in both observational and experimental oceanography for exploring many types of processes; we hope that all scientists in chemical oceanography will be able to find this theme applicable to their work. In addition to oral and poster presentations by the early-career participants, the GRS co-chairs have also invited a small panel of speakers to discuss career track and professional development topics pertinent to junior members of the field. Coupling the GRS with the GRC will greatly amplify the educational and professional experience of the students/postdocs, and will likely improve their ability to communicate their research at the subsequent GRC.

The program for the GRS in Chemical Oceanography will be developed by inviting speakers and discussion leaders from abstracts submitted by April 22, so we encourage all graduate students and postdocs planning to attend the GRS to submit an application by this deadline. Some funding will be available for graduate students and postdocs attending both the GRS and GRC. If the meeting cost is a barrier to your attendance, please contact the chairs to request additional need-based support.

Child and Family Care Resources: The Gordon Research Conferences (GRC) provides detailed information for each conference site on the GRC website. Although GRC does not directly provide child care services, attendees are welcome to have guests (including spouses, children, nannies and babysitters) accompany them to the conference. GRC also offers an alternative off-site registration fee at all conferences to accommodate those with special family care needs (the off-site fee includes the conference and all meals but enables attendees to book their own accommodations). The GRC website includes information on nearby off-site accommodations and links to area organizations, that can assist attendees with locating licensed child care providers and daycare services. Please note that Colby Sawyer College also offers a daily recreational camp for children (ages 6-12).

PhD position, EcoLab, Toulouse, France

Gaël Le Roux and François De Vleeschouwer are seeking for an excellent candidate to pursue a PhD at EcoLab, Toulouse, France. The full description is in this document.

The PhD attribution is pending a grant call where our subject has been ranked priority amongst other Earth Science topics. The candidate will have to go through an interview where a jury of the University of Toulouse will select the best candidate+subject combo.

While these grants are generally for French students, we feel that it may interest much more students abroad and that an excellent candidate (ranked first or second of his class) would have all his chance to get a grant.

We are willing to fund the travel expenses linked to the interview.

If you know any excellent candidate, please let her/him know. Please feel free to transfer to any colleague who may be interested.

Any candidate should contact us by email first, before April 25th in order to evaluate his/her dossier first and allocate time to apply further online

Postdoctoral position in elemental medicine, University of Southern California, USA

We invite applications for a postdoctoral position studying the application of stable isotopes to medical research. The candidate will explore a variety of isotope systems including both ‘traditional’ stable isotope systems (e.g. δ13C, δ15N, and δ33S) and non-traditional isotope systems (e.g. δ65Cu, δ56Fe, and δ66Zn). The candidate will be responsible for developing new analytical protocols for work with biological samples, including both fluid and tissue. Experience in some aspect of elemental or stable isotope analytical chemistry is necessary. Experience in ICPMS or similar techniques is desired, particularly experience in multi-collector ICPMS. This interdisciplinary project requires a candidate with an ability to communicate clearly across a wide range of subject areas from isotope geochemistry to medicine, and with a passion for analytical excellence applied to the science of human health.

Departure of the French HERMINE cruise in the Atlantic Ocean

The HERMINE cruise is about to depart from Mindelo (Cape Verde) and return on April 29th in Las Palmas (Gran Canaria). Onboard the French oceanographic research vessel Pourquoi Pas ?, a team of 40 scientists will study the hydrothermal activity around the Trans-Atlantic Geotraverse (TAG) site (see map below).

Indeed, the hydrothermal activity along mid-ocean ridges is a fundamental process controlling the exchances of heat and chemial species between the ocean crust and seawater. Hydrothermal vents can serve as sources or sinks for many trace elements in the ocean. It has long been thought that iron and other trace metals were mostly removed in the vicinity of the vents, being incorporated into iron oxy-hydroxide or sulfide minerals, and thus not exported into the deep ocean. However, recent studies showed that iron can be stabilized in hydrothermal plumes and transported together with other trace metals, far across the ocean, up to thousands kilometers away from the vent source.However, little is known so far on the processes occurring from the fluid exit to the distal far-field non-buoyant plume, particularly in regions where seafloor massive sulfide (SMS) deposits are observed, such as at the vicinity of slow-spreading ridges and back-arc basins.

The Hydrothermal Exploration and Research for Mineralisation In New Environments (HERMINE) GEOTRACES process study (GPrA07) aims to answer at the following questions:

  1. What are the concentrations of metals, their physical (particulate/dissolved) and chemical (redox/organic/inorganic) speciation within the plume?
  2. What role do biogeochemical processes play in controlling trace element and gas distribution in hydrothermal plumes? What are the dispersal and biogeochemical reactivity of these elements?
  3. Can we establish a reliable baseline for the actual hydrothermal plume functioning, using a multiscale chemical and microbial mapping of hydrothermal plumes in order to further assess the potential impact of seabed mining?
