Libby Jewett, Ph.D.

Director, NOAA Ocean Acidification Program

Dr. Libby Jewett became the founding Director of the NOAA Ocean Acidification Program in May 2011, and has been busy ever since building, organizing and steering the NOAA OAP enterprise. As a founding member of NOAA's Ocean Acidification Steering Committee, convened first in 2007, Jewett co-led NOAA-wide meetings of scientists and policymakers to conceive and develop NOAA's first comprehensive ocean acidification research plan. She chairs the Ocean Acidification Interagency Working Group (under the Subcommittee on Ocean Science and Technology) where she helped develop an ocean acidification strategic research plan for the nation. She is co-chair of the Executive Council of the newly formed Global Ocean Acidification Observing Network. Prior to becoming Director, she directed the only two national competitive hypoxia research funding programs as program manager for the Center for Sponsored Coastal Ocean Research in NOAA's National Ocean Service. Jewett earned a Ph.D. in Biology with a focus on Marine Ecology at the University of Maryland, a Master of Public Policy at Harvard University's Kennedy School of Government, and a B.A. at Yale University.

Dwight Gledhill, Ph.D.

Deputy Director, NOAA Ocean Acidification Program

Dr. Gledhill serves as the Deputy Director of the NOAA Ocean Acidification Program office in Silver Spring, MD. Previously he was an associate scientist with the UM/RSMAS Cooperative Institute of Marine & Atmospheric Sciences (CIMAS) with NOAA’s Atlantic Oceanographic & Meteorological Laboratory Ocean Chemistry Division where he advanced ocean acidification research primarily related to monitoring and understanding the process of ocean acidification within coral reef ecosystems. He was instrumental in establishing the NOAA Coral Reef Conservation Program (CRCP) Atlantic Ocean Acidification Test-bed (AOAT) in La Parguera, Puerto Rico, and recently another test-bed within the Florida Keys National Marine Sanctuary. He also has worked on the development of a satellite-based ocean acidification data synthesis product for the Greater Caribbean Region that scales up discrete ship-based observations of surface ocean carbonate chemistry. The model produces synoptic monthly fields of carbonate chemistry including aragonite saturation state and CO2 partial pressure that can be used to track regional and seasonal changes in carbonate chemistry related to ocean acidification and can be accessed at NOAA Coral Reef Watch. Gledhill has also been a contributor to numerous strategic planning documents related to ocean acidification within NOAA including leading the development of the Southeast/GOM Regional Strategic Plan on ocean acidification and CRCP OA science plan. Gledhill received his M.S. and  Ph.D. from the Department of Oceanography at Texas A&M University in 2005 where he primarily investigated carbonate mineral kinetics in complex electrolyte solutions as well as the sediment biogeochemistry associated with methane clathrates in the Northern Gulf of Mexico.

Paul McElhany, Ph.D.

OA Project Lead, NOAA Northwest Fisheries Science Center (NWFSC)

Dr. Paul McElhany has been research ecologist with the NOAA Northwest Fisheries Science Center since 1999. He currently leads the NWFSC ocean acidification research team. The research team uses laboratory species-exposure experiments, food web ecosystem modeling, and field work to understand the impact of ocean acidification along the Washington-Oregon coast. Dr. McElhany received his Ph.D. from Indiana University in 1997 followed by a post doc at the University of Oregon. Previously at NOAA, he focused on estimating extinction risk and developing recovery strategies for threatened salmon populations. He continues to have an interest in risk evaluation and recently participated in a review of several tropical coral species, particularly considering risks from ocean acidification.

Jeremy Mathis, Ph.D.

Director, Arctic Research Program, Climate Program Office

Mathis received a B.S. in Chemical Engineering from McNeese State University and a  Ph.D. in Marine Chemistry from the University of Miami - RSMAS. His graduate work focused on the marine carbon cycle in the western Arctic Ocean. Afterwards, he completed a postdoctoral project working on the inorganic carbon system as part of the Climate Variability and Predictability program (CLIVAR).

He then took a faculty position at the University of Alaska Fairbanks where he developed a diverse OA research program for the northern Gulf of Alaska, the Bering Sea, and the western Arctic Ocean making some of the first OA observations in the high latitude Pacific region of the Arctic. Mathis joined NOAA in 2012 as an oceanographer at the Pacific Marine Environmental Laboratory where he continued to work on high-latitude ocean acidification projects. Recently, Mathis became the Director of NOAA's Arctic Research Program in the Climate Program Office, which funds a diverse array of projects focused on constraining the drivers and impacts of a rapidly changing Arctic.

Rik Wanninkhof, Ph.D.

Oceanographer, NOAA Atlantic Oceanographic and Meteoroloigical Laboratory (AOML)

Rik Wanninkhof is an oceanographer at the Atlantic Oceanographic and Meteorological Laboratory of NOAA in Miami FL, USA. He studies the oceanic inorganic carbon cycle with a focus on the anthropogenic perturbation thereof. He has done extensive research on the transfer of carbon dioxide across the air-water interface. His research portfolio is comprised of several sustained observations projects including:

a. Measurements of partial pressure of CO2 from ship of opportunity funded by the Climate Observation Division NOAA Climate Program Office. He leads the effort that involves PI’s from four different institutions and 14 ships of opportunity, making it the largest consolidated effort in the world. The focus is on characterization of surface water CO2 levels and sea-air CO2 fluxes.

b. GOSHIP repeat hydrography that detects changes in anthropogenic CO2 in the ocean and natural and climate induced variability on decadal time scales by repeat occupations of global ocean transects. The effort is funded by the Climate Observation Division NOAA Climate Program Office.

c. Coastal Ocean Acidification Monitoring of Gulf Coasts and East Coast. This new program utilizes moorings, ships of opportunity, and research cruises to characterize the ocean acidification trends along the East and Gulf Coast. The effort is sponsored by the NOAA Ocean Acidification Program.
