Jeffrey Polovina, Ph.D. is quantitative marine ecologist who has worked for the past 38 years at NOAA Fisheries directing and conducting ecosystem research and eventually serving as a senior scientist and the Chief of the Ecosystem and Oceanography Division (EOD) at the Pacific Island Fisheries Science Center, NOAA in Honolulu, Hi. His research focuses on understanding the spatial and temporal dynamics of marine ecosystems with an emphasis on high tropic levels. He began his career studying the Hawaiian Islands coral reef ecosystem trophic web where he developed the ecosystem model approach ECOPATH. Over the past several decades, he and colleagues have focused on physical biological linkages in marine ecosystems, especially regime shifts and climate impacts. A related area of interest is to use electronic tags and remotely-sensed oceanographic data to understand how large pelagic animals use oceanic habitats. This work led to identifying the trans-Pacific Transition Zone Chlorophyll Front (TZCF) as important mid-latitude forage and migration habitat. His current research uses climate and ecosystem models and data to identify potential fishing and climate impacts on marine ecosystems. Recently he led the Science Center’s development of the Pacific Islands Climate Science Research Plan.
While most of his work focuses on the central North Pacific and the Pacific Islands, Dr. Polovina has had 2 Fulbright Senior Research awards for work in Kenya and the Galapagos. Dr. Polovina is also adjunct faculty appointments in the Oceanography and Marine Biology Departments at the University of Hawaii and as a Senior Fellow at the Joint Institute of Marine and Atmospheric Research (JIMAR) in Hawaii. In 2010 he received the Wooster Award from the North Pacific Marine Sciences Organization (PICES). He has a B.S. in mathematics from Carnegie-Mellon University and a Ph.D. in mathematical statistics from U.C. Berkeley.
Nicolás L. Gutiérrez is a Fishery Resources Officer in the Fisheries and Aquaculture Department of the Food and Agricultural Organization (FAO) based in Rome, Italy. In his role, he supports the design and implementation of programs of assistance to member countries in their tuna and tuna-like resource assessments, fisheries research and management activities, including implementation of the ecosystem approach to fisheries. He also provides advice and develop capacity-building programs on fisheries assessment and management, particularly in data-limited situations and to developing world fisheries. Prior to taking up his post at FAO in 2015, he was the Head of Research at the London-based Marine Stewardship Council were he led the teams responsible for the policy development process, science communications and training, and research and credibility. Nicolás has focused his research on the interplay among ecological processes, fisheries management, and co-management governance and on the impacts of market-based approaches such as certification and eco-labelling in achieving sustainable fisheries. He holds a PhD in fishery sciences from the University of Washington and an MSc in biology from the University of Uruguay. Nicolás has worked in fisheries management at the national and international level for more than 15 years and has taught several courses on marine conservation and fisheries stock assessment. He has received the Fulbright Scholarship, the Organization of American States' Initiative in Ecology Award, and a National Science Foundation fellowship (USA).
