Robert Nelson and Christopher Reddy recognized for pioneering use of GCxGC to track and understand marine pollution

Newswise — Woods Hole, Mass. (February 20, 2026) — Two chemical oceanographers from the Woods Hole Oceanographic Institution (WHOI) are being awarded the 2026 Lifetime Scientific Achievement Award by the International Symposium on Comprehensive Multidimensional Chromatography.

Robert Nelson and Christopher Reddy, both in the Department of Marine Chemistry and Geochemistry, are being recognized for more than 15 years of continuous, high-impact contributions in the field of comprehensive two-dimensional gas chromatography, commonly known as GCxGC

GCxGC is an advanced analytical technique that separates and identifies highly complex mixtures of chemicals with exceptional detail.

With more than 60 years of combined experience, Nelson and Reddy have pioneered the use of this method to analyze pollutants in the ocean, revolutionizing the field of oil-spill forensics. Their work has advanced scientific understanding and informed response strategies for some of the most significant oil spills in recent history, including the 2010 Deepwater Horizon disaster, as well as spills in San Francisco, Massachusetts, Florida, Texas, and California, and internationally in Brazil, Sri Lanka, Mauritius, Korea, and Japan.

“As an oceanographer, I am particularly proud that this award is selected by, and presented to, analytical chemists—a field dedicated to advancing how chemicals are measured,” Reddy said. “It is a tremendous honor to have our work recognized by this community.”

“What is especially meaningful to me is that Chris and I worked so closely together—often on site collecting samples on boats and beaches, analyzing them, and writing about the results,” Nelson added. “This award reflects not just our technical work, but a long-term partnership forged in the field and in the lab.”

The Lifetime Scientific Achievement Award for GCxGC Research is one of the highest honors bestowed by the GCxGC community, recognizing sustained innovation and impact in analytical chemistry and separation science. Nelson and Reddy will receive the award at the 44th International Symposium on Capillary Chromatography & 21st GCxGC Symposium in Riva del Garda, Italy, this spring.

About Woods Hole Oceanographic Institution

The Woods Hole Oceanographic Institution is a private, non-profit organization on Cape Cod, Massachusetts, dedicated to marine research, engineering, and higher education. Established in 1930, its primary mission is to understand the ocean and its interaction with the Earth as a whole, and to communicate an understanding of the ocean’s role in the changing global environment. Top scientists, engineers, and students collaborate on more than 800 concurrent projects worldwide—both above and below the waves—pushing the boundaries of knowledge and possibility.

Newswise — Woods Hole, Mass. (February 4, 2026) – Alan Seltzer, an affiliated scientist at Woods Hole Oceanographic Institution (WHOI), assistant professor at University College Dublin, and former WHOI postdoctoral scholar, has been named the 2026 recipient of the F.G. Houtermans Award by the European Association of Geochemistry (EAG). The award is among the highest international honors recognizing early-career scientists in geochemistry.

Seltzer is being recognized for pioneering the use of dissolved gas isotopes to quantify physical and biogeochemical processes across the Earth system, including exploring the sensitivity of groundwater systems to climate and the dynamics of atmosphere-ocean gas exchange. Much of the work cited by the award committee was conducted at WHOI, where Seltzer was a postdoctoral scholar from 2019 to 2021 and later a member of the scientific staff in the Marine Chemistry and Geochemistry Department, where he established a gas isotope tracer laboratory and developed several new analytical techniques.

His research helped open new pathways for using noble gas and nitrogen isotopes to investigate groundwater, seawater, air, and volcanic gases. Seltzer also helped extend high-precision noble gas isotope techniques to volcanic systems in collaboration with WHOI associate scientist Peter Barry to better understand the origins and transport pathways of volatiles from Earth’s deep interior. He also expanded oceanic applications of noble gas tracers for air-sea interaction and glacial meltwater circulation with WHOI scientists Bill Jenkins and Roo Nicholson, and more recently advanced high-precision tools for quantifying nitrogen cycling in aquatic environments in collaboration with MIT-WHOI Joint Program student Katelyn McPaul and WHOI associate scientist Scott Wankel.

“It is an honor to be recognized with the F.G. Houtermans Award,” Seltzer said. “WHOI has a special culture in which collaboration and high-risk science are celebrated, and without the encouragement and freedom at WHOI to take risks, push analytical limits, and fail a lot along the way, much of my work would not have been possible. I’m deeply grateful for all the support I’ve received from the WHOI community over my career so far.”

Seltzer’s selection continues a notable streak for WHOI’s Marine Chemistry and Geochemistry Department. Former WHOI postdoctoral scholar David Bekaert received the Houtermans Award in 2025, marking back-to-back years in which the honor has gone to WHOI-trained scientists—a rare distinction that highlights the strength and impact of the Institution’s postdoctoral program.

The 2026 F.G. Houtermans Award will be formally presented at the Goldschmidt Conference in July.
