Ricardo M Letelier is a Professor in the College of Earth, Ocean, and Atmospheric Sciences at Oregon State University. His research explores the response of marine pelagic microorganisms, populations, and communities to environmental perturbations and how this response affects marine biogeochemical cycles. His main areas of expertise are phytoplankton ecology and bio-optics. Letelier received his … Continued

I am a South African marine scientist whose work focuses on understanding how ocean systems function, particularly the processes that regulate nutrients, phytoplankton productivity, and the marine nitrogen cycle. I completed my PhD in Ocean and Atmospheric Sciences at the University of Cape Town in 2023, during which I developed a particular interest in trying … Continued

Pierre Marrec is a Marine Research Associate at the Graduate School of Oceanography, University of Rhode Island, with expertise in ocean biogeochemistry and plankton ecology. His research is primarily observation-based, and he has spent significant time at sea aboard research vessels. Marrec joined the OMI project in October 2024 as a part-time data manager and … Continued

Nick Hawco is a chemical oceanographer who is fascinated by life’s search for unique elements. Although they might compose only a few parts per trillion of ocean water, several metals – iron, cobalt, zinc, and manganese – remain essential for the metabolism of marine phytoplankton, animals, and bacteria. Out in the oligotrophic gyres, far from … Continued

I am a marine biologist from Argentina, currently a PhD candidate supported by CONICET, where I study coastal planktonic communities and how they respond to environmental variability. I grew up far from the ocean, in a landlocked region of the country, but early experiences with the sea sparked a deep curiosity that eventually shaped my … Continued

Mattia Da Fieno is a research technician for SUBSEA with a B.S in Global Environmental Science from the University of Hawai’i at Manoa. His background in oceanography started as a student assistant for the Hawai’i Ocean Timeseries (HOT) program, where he continues to work today, having totaled over 100 days at sea. His duties include … Continued

I study the ways that microorganisms catalyze the movement of elements through aquatic ecosystems. Most of my effort focuses on linking specific microorganisms to transformations of nitrogen, phosphorus, and carbon. Much of my research focuses on marine ecosystems and I enjoy the interdisciplinary nature of oceanography. My group has spent a lot of time working … Continued

María Luz Torres Alberto holds a Ph.D. in Biological Sciences with a specialization in Biological Oceanography, and is currently a postdoctoral researcher at the National Institute for Fisheries Research and Development (INIDEP, Argentina). Her focus is on ocean productivity and carbon cycling, with particular interest in net community production (NCP) derived from O₂/Ar and its … Continued

Kelly George is a Senior Faculty Research Assistant in Dr. Maria Kavanaugh’s Seascape Ecology Laboratory at Oregon State University, where they contribute to research on phytoplankton biodiversity and seascape dynamics in the Northern California Current. Kelly began working with Dr. Kavanaugh as an undergraduate volunteer in 2019, focusing on the use of an Imaging FlowCytobot … Continued

Katie Coates is an early-career biological scientist and recent graduate of the University of Montana, where she earned a B.S. in Wildlife Biology in May 2025. She currently works as a lab and field technician in the Church Lab at the Flathead Lake Biological Station at the University of Montana, supporting the SUBSEA project. With … Continued
