Available in PDF, EPUB and Kindle. Book excerpt: Study of salt marsh biophysical properties is imperative to understand its response to environmental change. We developed protocols for mapping biophysical properties of salt marshes such as Green Leaf Area Index (GLAI), Canopy Chlorophyll (CHLc), Vegetation Fraction (VF), and aboveground Green Biomass (GBM) using moderate resolution satellite images and in-situ data for the salt marshes in south-eastern United States. The time-series products derived using the biophysical models have been able to capture the spatio-temporal effects of the environmental events affecting the salt marshes of the region. We also tested the performance of different smoothing functions to derive noise-free phenology for Louisiana (LA) and Georgia (GA) salt marshes from the time-series GBM composites, and selected the best smoothing function to derive and analyze phenological parameters for salt marsh habitats. Long-term trend analysis of phenological parameters indicate positive changes in the base GBM values, and mostly negative changes in the GBM amplitude and small seasonal integral, which indicate overall progressive decline in the rates of photosynthesis and biomass allocation in the salt marsh ecosystem. This observed decline in photosynthesis and biomass allocation may be attributed to elevated atmospheric carbon dioxide (CO2) levels and sea level rise. Finally we attempted to map Gross Primary Productivity (GPP) for a salt marsh habitat in the Gulf Coast, using the GBM composites and in-situ GPP estimates from eddy covariance CO2 flux towers. The time-series composites and phenological charts developed using the biophysical GPP model was able to capture the effect of different environmental events such as dieback and hurricane landfall. The results illustrate the relative efficiency of MODIS in analyzing salt marsh biophysical properties. This is the first study to employ MODIS images to study the long-term trends in biophysical characteristics of salt marshes in south-east United States. The methods described in this study as well as the biophysical products derived using the methods has the potential to improve our ability to predict their productivity and carbon sequestration potential. These techniques could also be used to assess the success of previous and ongoing salt marsh restoration projects, and evaluate the productivity of marshes under threat from both natural and anthropogenic drivers.

Available in PDF, EPUB and Kindle. Book excerpt: The World of the Salt Marsh is a wide-ranging exploration of the southeastern coast—its natural history, its people and their way of life, and the historic and ongoing threats to its ecological survival. Focusing on areas from Cape Hatteras, North Carolina, to Cape Canaveral, Florida, Charles Seabrook examines the ecological importance of the salt marsh, calling it “a biological factory without equal.” Twice-daily tides carry in a supply of nutrients that nourish vast meadows of spartina (Spartina alterniflora)—a crucial habitat for creatures ranging from tiny marine invertebrates to wading birds. The meadows provide vital nurseries for 80 percent of the seafood species, including oysters, crabs, shrimp, and a variety of finfish, and they are invaluable for storm protection, erosion prevention, and pollution filtration. Seabrook is also concerned with the plight of the people who make their living from the coast’s bounty and who carry on its unique culture. Among them are Charlie Phillips, a fishmonger whose livelihood is threatened by development in McIntosh County, Georgia, and Vera Manigault of Mount Pleasant, South Carolina, a basket maker of Gullah-Geechee descent, who says that the sweetgrass needed to make her culturally significant wares is becoming scarcer. For all of the biodiversity and cultural history of the salt marshes, many still view them as vast wastelands to be drained, diked, or “improved” for development into highways and subdivisions. If people can better understand and appreciate these ecosystems, Seabrook contends, they are more likely to join the growing chorus of scientists, conservationists, fishermen, and coastal visitors and residents calling for protection of these truly amazing places.

Book excerpt: This report is part of a series of community profiles on the ecology of wetland and marine communities. This particular profile considers tidal marshes of the southeastern Atlantic coast, from North Carolina south to northern Florida. Alone among the earth's ecosystems, coastal communities are subjected to a bidirectional flooding sometimes occurring twice each day; this flooding affects successional development, species composition, stability, and productivity. In the tidally influenced salt marsh, salinity ranges from less than 1 ppt to that of seawater. Dominant plant species include cordgrasses (Spartina alterniflora and S. cynosuroides), black needlerush (Juncus romerianus), and salt marsh bulrush (Scirpus robustus). Both terrestrail and aquatic animals occur in salt marshes and include herons, egrets ospreys (Pandion haliaetus), bald eagles (Haliaeetus leucocephalus), alligators (Alligator Mississippiensis), manatees (Trichecus manatus), oysters, mussels, and fiddler crabs. Currently, the only significant direct commercial use of the tidal salt marshes is by crabbers seeking the blue crab Callinectes sapidus, but the marshes are quite important recreationally, aesthetically, and educationally. 151 refs., 45 figs., 6 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: Key features: Captures the historic context and recent developments in science and policy arenas that address the potential for coastal wetlands to be considered as significant contributors to carbon sequestration Links multiple levels of science (biogeochemistry, geomorphology, paleoclimate, etc.) with blue carbon concepts (science, policy, mapping, operationalization, economics) in a single compendium Concludes with a discussion of future directions which covers integrated scientific approaches, impending threats and specific gaps in current knowledge Includes 7 case studies from across the globe that demonstrate the benefits and challenges of blue carbon accounting Written by over 100 leading global blue carbon experts in science and policy. Blue Carbon has emerged as a term that represents the distinctive carbon stocks and fluxes into or out of coastal wetlands such as marshes, mangroves, and seagrasses. The Blue Carbon concept has rapidly developed in science literature and is highly relevant politically, as nations and markets are developing blue carbon monitoring and management tools and policies. This book is a comprehensive and current compendium of the state of the science, the state of maps and mapping protocols, and the state of policy incentives (including economic valuation of blue carbon), with additional sections on operationalizing blue carbon projects and 7 case studies with global relevance.
