Tracers: How Chemistry Gives Insight into Ocean Processes


July 22-23, 2017


Colby-Sawyer College
New London, NH Site Information


Claire P. Till (née Parker) & Hilary I. Palevsky

Application Deadline

Applications for this meeting must be submitted by June 24, 2017. Please apply early, as some meetings become oversubscribed (full) before this deadline. If the meeting is oversubscribed, it will be stated here. Note: Applications for oversubscribed meetings will only be considered by the Conference Chair if more seats become available due to cancellations.

GRS Speaker Abstract Deadline: Although applications will be accepted until the date noted above, any applicants who wish to be considered for an oral presentation should submit their application by April 22, 2017. Please refer to the application instructions in the Meeting Description section below for more details (if available).

Meeting Description


The Gordon Research Seminar on Chemical Oceanography is a unique forum for graduate students, post-docs, 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 invited a small panel of speakers to discuss career track and professional development topics pertinent to junior members of the field. The panelists will be:

  • Lihini Aluhiware - Professor at Scripps Institution of Oceanography
  • David Hastings - Professor of Marine Science & Chemistry at Eckerd College
  • Sherry Lippiatt - California Regional Coordinator for NOAA Marine Debris Program / IMSG

Application Instructions

The meeting will feature approximately 10 talks and 2 poster sessions. All attendees are expected to actively participate in the GRS either by giving an oral presentation or presenting a poster. Therefore, all applications must include an abstract.

The Chairs will select speakers from abstracts submitted by April 22, 2017. Those applicants who are not chosen for talks and those who apply after the deadline to be considered for an oral presentation will be expected to present a poster. In order to participate, you must submit an application by the date indicated in the Application Deadline section above.

Related Meeting

This GRS will be held in conjunction with the "Chemical Oceanography" Gordon Research Conference (GRC). Those interested in attending both meetings must submit an application for the GRC in addition to an application for the GRS. Refer to the associated GRC program page for more information.
