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.

Download or read book Quantification of Salt Marsh Carbon Stocks written by Ranjani W. Kulawardhana and published by . This book was released on 2014 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent climatic change projections have increased scientific and public attention on the issues relating to carbon cycling patterns, its controls, and the importance of ecosystems in the cycling and sequestration process. Global carbon studies, however, primarily have focused on dry land ecosystems that extend over large areas and have not accounted for the relatively small and scattered, though highly carbon rich, ecosystems such as mangrove swamps and salt marshes. Using data from a Spartina alterniflora dominated salt marsh in Galveston, Texas this study integrates remote sensing data (multispectral and Light Detection and Ranging - lidar) with field measurements for the quantification of carbon pools in salt marsh ecosystems. Findings in this study show the capability of remote sensing data for the characterization of salt marsh terrain and vegetation heights and the estimation of above-ground biomass quantities. The best biomass prediction models using lidar heights reported considerably low errors, i.e. the percent root square errors (% RSEs) are close to 20%, which is the recommended error threshold for remote sensing based forest biomass prediction models. Our findings also demonstrate that lidar as compared to spectral data can provide better estimates of above-ground biomass and carbon, even in the herbaceous and low-relief context of a salt marsh. A clear zonation of terrain, vegetation characteristics and the distribution of biomass quantities within the marsh extent was also observed. Distribution of biomass quantities revealed linkages with the elevation. Variations in soil properties (i.e. carbon and bulk density) in the soil profile were linked to the temporal changes in soil carbon accumulations on the marsh surface, relative sea level history and resulting vegetation transitions as corroborated by historical aerial images. In general, the amounts of soil carbon stored in recently established Spartina alterniflora intertidal marshes were significantly lower than those that have remained in situ for a longer period of time. These findings indicate that, even though salt marshes can respond to relative sea level rise by migrating landward, their status as a carbon sink varies as a function of both space and time. Thus, in order to predict carbon in a wetland, researchers need to know not only the elevation, the relative sea level rise rate, and the accretion rate - but also the history of land cover change and vegetation transition. Findings of this study contribute to carbon quantification efforts in these vulnerable ecosystems. Further, these findings will also contribute to the increased understanding of the capabilities of remote sensing datasets and techniques for the quantification of these important carbon stocks.

This book was released on 2019-08-22 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, there has been an increase in the development of strategies for water ecosystem mapping and monitoring. Overall, this is primarily due to legislative efforts to improve the quality of water bodies and oceans. Remote sensing has played a key role in the development of such approaches—from the use of drones for vegetation mapping to autonomous vessels for water quality monitoring. Within the specific context of vegetation characterization, the wide range of available observations—from satellite imagery to high-resolution drone aerial imagery—has enabled the development of monitoring and mapping strategies at multiple scales (e.g., micro- and mesoscales). This Special Issue, entitled “Novel Advances in Aquatic Vegetation Monitoring in Ocean, Lakes and Rivers”, collates recent advances in remote sensing-based methods applied to ocean, river, and lake vegetation characterization, including seaweed, kelp, submerged and emergent vegetation, and floating-leaf and free-floating plants. A total of six manuscripts have been compiled in this Special Issue, ranging from area mapping substrates in riverine environments to the identification of macroalgae in marine environments. The work presented leverages current state-of-the-art methods for aquatic vegetation monitoring and will spark further research within this field.

Download or read book Earth Observation for Land and Emergency Monitoring written by Heiko Balzter and published by John Wiley & Sons. This book was released on 2017-03-14 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth Observation Science (EOS) is the study of the global Earth land-ocean-atmosphere system through observations. The principal tools for such studies are measurements from space since these provide the coverage of the planet that is necessary to capture the behaviour of the entire coupled system. In addition, surface observations, and measurements from aircraft, balloons and sounding rockets provide valuable contributors to what are now termed "integrated, global observing systems.” Coupled with models, the EOS measurement suites provide powerful tools for research into the factors controlling and changing the Earth system in which we live. The objectives of this book are to describe new methods and applications of satellite technology in the fields of land and emergency monitoring. It draws on new research outcomes from the European FP7 project GIONET (European Centre of Excellence in Earth Observation Research Training). GIONET combines industrial partners with universities and research institutes, and this book provides a perspective on Earth Observation applications that is motivated by the cross-fertilisation of both sectors. Hence, this book will find readers in both industry and academia. This book highlights a broad range of innovative uses of Earth Observation technology to support environmental management, decision making, crisis management and climate policies. It uses advanced concepts of multi-sensor image integration, multi-temporal analysis and synergies between data and models. This is a truly interdisciplinary subject that encompasses a range of applications in various fields which are discussed in detail throughout the text. If you are interested in remote sensing applications and looking for inspiration, this is the book for you.

Download or read book The World of The Salt Marsh written by Charles Seabrook and published by University of Georgia Press. This book was released on 2013-05-01 with total page 381 pages. 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.
Download or read book Salt Marshes written by Duncan M. FitzGerald and published by Cambridge University Press. This book was released on 2021-04-22 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salt marshes are highly dynamic and important ecosystems that dampen impacts of coastal storms and are an integral part of tidal wetland systems, which sequester half of all global marine carbon. They are now being threatened due to sea-level rise, decreased sediment influx, and human encroachment. This book provides a comprehensive review of the latest salt marsh science, investigating their functions and how they are responding to stresses through formation of salt pannes and pools, headward erosion of tidal creeks, marsh-edge erosion, ice-fracturing, and ice-rafted sedimentation. Written by experts in marsh ecology, coastal geomorphology, wetland biology, estuarine hydrodynamics, and coastal sedimentation, it provides a multidisciplinary summary of recent advancements in our knowledge of salt marshes. The future of wetlands and potential deterioration of salt marshes is also considered, providing a go-to reference for graduate students and researchers studying these coastal systems, as well as marsh managers and restoration scientists.
Download or read book Salt Marshes written by Judith S Weis and published by Rutgers University Press. This book was released on 2009-07-16 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tall green grass. Subtle melodies of songbirds. Sharp whines of muskrats. Rustles of water running through the grasses. And at low tide, a pungent reminder of the treasures hidden beneath the surface.All are vital signs of the great salt marshes' natural resources. Now championed as critical habitats for plants, animals, and people because of the environmental service and protection they provide, these ecological wonders were once considered unproductive wastelands, home solely to mosquitoes and toxic waste, and mistreated for centuries by the human population. Exploring the fascinating biodiversity of these boggy wetlands, Salt Marshes offers readers a wealth of essential information about a variety of plants, fish, and animals, the importance of these habitats, consequences of human neglect and thoughtless development, and insight into how these wetlands recover. Judith S. Weis and Carol A. Butler shed ample light on the human impact, including chapters on physical and biological alterations, pollution, and remediation and recovery programs. In addition to a national and global perspective, the authors place special emphasis on coastal wetlands in the Atlantic and Gulf regions, as well as the San Francisco Bay Area, calling attention to their historical and economic legacies. Written in clear, easy-to-read language, Salt Marshes proves that the battles for preservation and conservation must continue, because threats to salt marshes ebb and flow like the water that runs through them.
Download or read book The Ecology of a Salt Marsh written by L. R. Pomeroy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecologists have two long-standing ways to study large ecosystems such as lakes, forests, and salt-marsh estuaries. In the first, which G. E. Hutchinson has called the holological approach, the whole ecosystem is first studied as a "black box," and its components are investigated as needed. In the second, which Hutchinson has called the merological approach, the parts of the system are studied first, and an attempt is then made to build up the whole from them. For long-term studies, the holological approach has special advantages, since the general patterns and tentative hypotheses that are first worked out help direct attention to the components of the system which need to be studied in greater detail. In this approach, teams of investigators focus on major func tions and hypotheses and thereby coordinate their independent study efforts. Thus, although there have been waves, as it were, of investigators and graduate students working on different aspects of the Georgia salt-marsh estuaries (personnel at the Marine Institute on Sapelo Island changes every few years), the emphasis on the holo logical approach has resulted in a highly differentiated and well-coordinated long-term study. Very briefly, the history of the salt-marsh studies can be outlined as follows. First, the general patterns of food chains and other energy flows in the marshes and creeks were worked out, and the nature of imports and exports to and from the system and its subsystems were delimited.
