The climate study team will participate in three annual EcoMon cruises aboard the 155-foot NOAA Fisheries Survey Vessel Delaware II, based at the NEFSC’s laboratory in Woods Hole, Mass. The most recent cruise returned to Woods Hole on February 18.
Findings from the climate impact project, funded by NASA, will help scientists better understand how annual and decadal-scale climate variability affects the growth of phytoplankton, which is the basis of the oceanic food chain. The project will also examine organic carbon distributions along the continental margin of the East Coast and collect data for ocean acidification studies.
John O’Reilly of the satellite ocean productivity group and Kimberly Hyde of the ecosystem assessment program at NEFSC’s Narragansett, R.I., laboratory are co-principal investigators on the CliVEC project. Laboratory colleague Jon Hare, an oceanographer and plankton specialist, oversees the EcoMon program and is a collaborator on the new climate study.
“The CliVEC program will provide a more complete understanding of the northeast U.S. shelf ecosystem,” said Hare. “It extends our EcoMon survey efforts, and we are excited about the new knowledge and advances in satellite models that we will all gain from this collaboration and pooling of resources.”
O’Reilly has had a long collaboration with NASA scientists in developing algorithms for processing data from ocean color remote sensors on satellites that provide global maps of ocean surface characteristics. The satellite-transmitted data can also be used to develop oceanic primary production models and algorithms that measure carbon distributions in the ocean.
Other lead investigators in the CliVEC project include Antonio Mannino from NASA’s Goddard Space Flight Center (GSFC), Margaret Mulholland from Old Dominion University (ODU), and David Lary from the NASA-affiliated University of Maryland Baltimore County Joint Center for Earth Systems Technology. The team of scientists from GSFC and ODU is conducting water sampling and experiments to quantify primary productivity and carbon distributions.
"Phytoplankton are the foundation of the food chain in the ocean and produce about half of the oxygen on Earth," said Mannino. "By understanding the distribution of phytoplankton populations and how they react to natural and anthropogenic forcing, we can better predict future responses of phytoplankton and possibly even fisheries."
The Northwest Atlantic location was chosen for the CliVEC study because it is the crossroads between major ocean circulation features like the Gulf Stream and the Labrador Current.
Discharges from rivers, seasonal changes in water column density stratification, the freshening of surface waters from melting of the Greenland ice sheet, and other climate-related factors can all alter ocean circulation patterns and affect the strength, timing and location of phytoplankton blooms, potentially decreasing annual primary production and changing ocean biology.
Scientific activities during the recent 18-day cruise included collecting water samples from the surface to the ocean floor for a variety of chemical measurements, and sampling to identify the incursion of Labrador Current water into the Gulf of Maine. Instruments were also deployed to measure sea surface temperatures and salinities and to collect data on chlorophyll, oxygen and nitrate levels, and the depth of light transmission for primary productivity.
In addition to the CliVEC activities, zooplankton samples were collected for the Census of Marine Zooplankton Project. Standard EcoMon sampling was also done, extending oceanographic and plankton time series that started in the early 1970s. Two observers were aboard to identify and count seabirds, and sightings of northern right whales and other whale species were recorded.
NOAA Fisheries Service is dedicated to protecting and preserving our nation’s living marine resources and their habitat through scientific research, management and enforcement. NOAA Fisheries Service provides effective stewardship of these resources for the benefit of the nation, supporting coastal communities that depend upon them, and helping to provide safe and healthy seafood to consumers and recreational opportunities for the American public.
NOAA understands and predicts changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and conserves and manages our coastal and marine resources. Visit us at http://www.noaa.gov or on Facebook at http://www.facebook.com/noaa.lubchenco.
