Departure of the French PEACETIME cruise in the Mediterranean Sea

The PEACETIME* cruise will depart on May 10 from La Seyne (France) for a 33 days cruise. Onboard the French oceanographic research vessel Pourquoi Pas ?, there will be a team of 40 scientists who will study the impact of atmospheric deposition on the ocean. This international and multidisciplinary scientific team will travel the central and western Mediterranean in search of atmospheric deposition of Saharan dust. Their aim is to study processes at the interface between the atmosphere and the ocean in this region of the world where atmospheric input plays a key role as a nutrient source for the marine biosphere. This campaign will allow to better understand how atmospheric deposition affects the functioning of the pelagic ecosystem in order to more accurately predict the future of biodiversity in the Mediterranean.

On board, the scientific team will combine in situ observations in the atmosphere and ocean with process studies in the water column. This will allow to characterize the chemical, biological and physical properties of the atmosphere, the marine surface micro-layer, and the deeper layers of the Mediterranean.

In order to optimize the chances of observing a deposition of Saharan dust in situ during the cruise, the cruise track is in a zone where the probability of this type of event is greatest. In the event of such an occurrence, the vessel will be diverted from its original transect to the identified deposit area. Another specific features of this campaign is to embark "climatic reactors" that are devices reproducing on a small scale the air-sea exchanges under current and future environmental conditions (acidification and increase of the temperature of the sea water).

This coordinated multidisciplinary effort will better characterize the impact of atmospheric deposition in the ocean and their feedback to the atmosphere in a nutrient-poor system such as the Mediterranean Sea. PEACETIME is a GEOTRACES Process-study (GApr09).

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).
