Christopher Chambers

NOAA/NMFS Northeast Fisheries Science Center, Howard Laboratory

Chris is a senior research biologist and leader of the Life History and Recruitment Group at the NOAA Fisheries, Northeast Fisheries Science Center’s Howard Laboratory in Highlands, New Jersey.  His research interests are directed towards the pattern, sources, and consequences of environmentally induced phenotypic variation in fishes.  He takes a three-pronged approach with specifics varying with the current knowledge on the focal topic and taxa.  First, patterns of variation are summarized from his group’s own field and experimental work, augmented by retrospective and comparative studies where appropriate.  Second, sources of variation are usually dealt with in an experimental laboratory context where environmental factors (e.g., temperature, CO2, dissolved oxygen, contaminants) as well as parental contribution to offspring trait variance are assessed in a systematic and statistically rigorous way.  Third, consequences of variation are addressed through experimental studies of selection, from field evidence of selective mortality, or from a modeling framework.  Most of these studies use the early life-stages of marine fishes as subjects because of the magnitude and potential high selective consequences of mortality.  His laboratory facilities at NOAA have the capability of spawning adults and culturing of eggs, larvae, and juveniles in numbers suited for most appropriate experimental designs.  In the ocean acidification context, Chris and his group are applying these experimental methodologies to address the biological responses of finfish, including flatfish and codfish, to elevated CO2 and environmental co-stressors.  Of special interest are responses of the vulnerable early life-stages of fish, how effects pertain to ecological important processes, and the potential of these species to adapt to current and future conditions of coastal and oceanic habitats.

Derek Manzello, Ph.D.

NOAA Atlantic Oceanographic and Atmospheric Marine Laboratory

Derek Manzello is the lead PI of the Coral Reef Monitoring Network in the Atlantic. His research explores how climate change and ocean acidification will, and, already are, affecting the construction (coral growth, calcification) and breakdown (bioerosion, dissolution) of coral reefs, as well as the associated ramifications this has for ecosystem function (e.g., biodiversity). He utilizes a unique interdisciplinary approach that incorporates aspects of biology, chemistry, and geology within an ecological framework.

He is currently overseeing and maintaining: 1) in situ climate and ocean acidification requirements of the NOAA Coral Reef Conservation Program’s (CRCP) National Coral Reef Monitoring Plan, and 2) CRCP’s Atlantic Ocean Acidification Test-Bed, both of which are within the Atlantic basin. Coincident with these efforts, he is measuring how multiple species of coral calcify, as well as how rates of bioerosion vary across natural COgradients on US coral reefs. This involves experimental work to understand how important coral reef species affect seawater carbonate chemistry and their response to high CO2.
