Principal Investigators

GCOOS is primarily funded by the U.S. Integrated Ocean Observing System (IOOS) through a Cooperative Institute in five-year cycles. Our most recent proposal for funding covers 2021-2026 under the project title “Continuing the Development of the Gulf of Mexico Coastal Ocean Observing System.”

In turn, GCOOS develops partnerships with academic, NGOs and industry to support ocean observations and platforms in the Gulf of Mexico. Sub-award proposals are selected competitively based on system-wide needs and awarded to Principal Investigators.

GCOOS has also received additional funding through special supplements: Disaster Supplements to “Accelerate Improvements in Hurricane Intensity Forecasting through Underwater Glider Field Campaigns” (Sept. 1, 2022-Aug. 30, 2025) and “Repairs and Replacements of Marine Observational Assets Damaged during 2020 and 2021 in the Gulf of Mexico” (Sept. 1, 2022-Aug. 31, 2024) along with funding through the Bipartisan Infrastructure Law for “Modernization and Recapitalization of the Gulf of Mexico Coastal Ocean Observing System” (Jan. 1, 2023-June 30, 2023).

Dr. Lisa Campbell
Dr. Lisa Campbell
Regents Professor and recipient of the William R. Bryant Endowed Chair in the Department of Oceanography - Texas A&M University

Dr. Lisa Campbell received her M.S. and Ph.D. from SUNY Stony Brook (now Stony Brook University) and was a Research Scientist at the University of Hawaii before joining the faculty at Texas A&M University in 1996. Currently, she is a Regents Professor and recipient of the William R. Bryant Endowed Chair in the Department of Oceanography. She has had a joint appointment in the Department of Biology since 2001. Her research focuses on the diversity and population dynamics of marine phytoplankton. Although she has worked in all oceans, her current research centers on harmful algal blooms in the Gulf of Mexico. Dr. Campbell pioneered the use of the Imaging FlowCytobot (IFCB) as a monitoring tool for harmful algae. The IFCB combines flow cytometry and video technology to capture images of individual algal cells in real time. Using this autonomous system, she has established a long-term high temporal resolution phytoplankton time series and has provided successful early warning for potential harmful algal blooms since 2007. Dr. Campbell has been recognized at TAMU for a Distinguished Achievement in Teaching (2015), a Women’s Faculty Network Outstanding Mentoring Award (2014), Dean’s Distinguished Achievement Award for Faculty Research (2009) and is a Sustaining Fellow of the Association for the Sciences of Limnology & Oceanography (ASLO). She served as Secretary on the Board of Directors ASLO from 2009-2018 and currently serves as an Associate Editor for the Journal of Plankton Research. She has published over 100 peer-reviewed publications.
