Upcoming Seminars

Long-term Interdisciplinary Monitoring of the Ecological Impacts of Ocean Acidification on Coral Reefs Across the Central and Western Pacific

Date: Thursday, December 3, 2015 at 12:00pm EST

Speaker: Rusty Brainard, Ph.D., Chief, Coral Reef Ecosystem Program, NOAA Pacific Islands Fisheries Science Center

Abstract: Ocean acidification is predicted to have significant impacts on coral reefs and the associated ecosystem services they provide to human societies over this century. To inform, validate, and improve laboratory experiments and predictive modelling efforts, scientists and managers from NOAA, IOC-WESTPAC, SPREP, and the countries of the western and central Pacific Ocean are collaborating to establish an integrated and interdisciplinary observing network to assess spatial patterns and monitor long-term temporal trends of the ecological impacts of ocean acidification on coral reef ecosystems across gradients of biogeography, oceanography, and anthropogenic stressors. Using standardized and comparable approaches and methods, these collaborative efforts are beginning to systematically monitor: seawater carbonate chemistry using water sampling and moored instruments, benthic community structure and abundance using biological surveys and photoquadrats, indices of crytobiota diversity using autonomous reef monitoring structures, net accretion and calcification rates using calcification accretion units and coral cores, and bioerosion rates. NOAA has established baseline observations and initiated long-term monitoring at 23 U.S.-affiliated sites in Hawaii, American Samoa, Guam, the Northern Marianas, Jarvis, Howland, and Baker Islands, and Palmyra, Kingman, Wake, and Johnston Atolls, and 2 sites in the Coral Triangle (Philippines and Timor Leste). Following two successful IOC-WESTPAC workshops, 22 additional sites are being initiated in Bangladesh (1), Cambodia (1), China (1), Indonesia (3), Malaysia (5), Philippines (7), Thailand (3), and Vietnam (1). Following two workshops and with support from New Zealand, SPREP has initiated efforts to identify multiple pilot ocean acidification monitoring sites in the Small Island Developing States of the Pacific Islands adopting similar approaches. Collectively, these standardized observations of the ecological responses to ocean acidification will inform resource managers and policymakers in their efforts to implement effective management and adaptation strategies and serve as a model for the Global Ocean Acidification Observing Network (GOA-ON).

About the Speakers: Dr. Rusty Brainard is a supervisory oceanographer and founding Chief of NOAA’s Coral Reef Ecosystem Division (CRED), an interdisciplinary, ecosystem-based research program that conducts integrated ecosystem observations, long-term monitoring, and applied research of coral reefs to support ecosystem-based management and conservation. CRED monitors the distribution, abundance, diversity, and condition of fish, corals, other invertebrates, algae, and microbes in the context of their diverse benthic habitats, human pressures, and changing ocean conditions, including ocean acidification (OA) and warming.

Remote access via webinar will be available. See the General Information section above for details.

The physical basis for decadal climate predictions and the GFDL decadal climate prediction system

Date: Thursday, January 28, 2016 at 12:00pm EST

Speaker: Thomas L. Delworth, PhD, NOAA/Geophysical Fluid Dynamics Laboratory, Princeton, NJ

Abstract: There have been remarkable changes in the climate system over the last few decades, ranging from a rapid reduction in Arctic sea ice to changes in Atlantic hurricane actvity to prolonged drought in the western U.S. These changes are a combination of the response of the climate system to anthropogenic forcing and natural climate variability. There is tremendous societal interest in understanding the nature of such decadal scale climate changes, and the extent to which they can be predicted in advance.

In this talk we present the physical basis for making predictions of how the climate system will change over the next decade due to both natural variability and anthropogenic radiative forcing changes. We summarize what parts of the climate system may be predictable on such timescales, and the physical processes that create such predictability. We then describe a prototype decadal prediction system that has been developed at NOAA's Geophysical Fluid Dynamics Laboratory (GFDL), and present results from experimental decadal predictions that have been performed over the last several years.

About the Speaker: Dr. Delworth is a Research Scientist at NOAA's Geophysical Fluid Dynamics Laboratory (GFDL) and member of the GFDL Science Board. He is also on the faculty of the Atmospheric and Oceanic Sciences Program at Princeton University.

Remote access via webinar will be available. See the General Information section above for details.
