Book excerpt: From a modern-day perspective, it may seem odd that people should have chosen to dwell in the open salt-marsh landscape along the Wadden Sea coast. While the beauty of the salt marshes is widely acknowledged, the idea of living there seems to suggest struggle and misery. Yet the salt-marsh settlers, dwelling on their settlement mounds or terps, did not just ‘survive' or ‘get by', but actually managed to live a good life, by embracing this marshy world and its peculiarities. This collection of papers focuses on foraging, farming and food preparation in the context of the salt-marsh environment. The various contributions celebrate the career and work of Annet Nieuwhof, who has been an inspirational colleague and great friend to many of us. She passionately embraced terp research, always actively stimulating cooperation across disciplines as well as national borders. Reflecting some of Annet's wide-ranging interests, the present volume is dedicated to her in friendship and gratitude.

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 Salt Marsh Responses to Oil Contamination Following the Deepwater Horizon Oil Spill written by and published by . This book was released on 2018 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Deepwater Horizon oil spill, which occurred from April to July of 2010, was the largest spill in U.S. history. Oil washed onto hundreds of kilometers of intertidal marsh shoreline resulting in widespread plant mortality and short-term reductions in ecosystem function. Past incidences of oiling have shown that marsh recovery trajectories can vary greatly over space and time. Accordingly, the long-term negative effects of an oil spill of this magnitude on marsh ecosystems remains largely unknown. This dissertation investigates the effects of oil contamination from the Deepwater Horizon oil spill on community dominant plant species distributions and land loss rates and, simultaneously, demonstrates the value of employing advanced remote sensing and GIS techniques to address landscape-scale ecological disturbances. To examine the response of marsh plant communities to heavy oiling, dominant species in heavily oiled salt marshes, an image classification system was developed to map dominant species. This classification approach utilizes canonical discriminant analysis (CDA), along with a library of field-referenced image endmembers collected from a time series of Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) images (2010-2012). Land loss rates were calculated using the normalized difference vegetation index (NDVI)applied to a time series (2006-2016) of high resolution (0.30-0.64 m) orthorectified image datasets. Finally, a simple, fetch-limited wind-wave model was integrated into the analysis of shoreline oiling and land loss to examine the interacting effects of wave characteristics and oiling on bay-wide land loss rates.This dissertation’s findings suggest that the most important impact of oiling along marsh boundaries is the acceleration of shoreline retreat and land loss. Further, the results imply that marsh responses to oil contamination are highly variable, and wave action is a significant factor in determining marsh recovery trajectories. Without high wave energy, marsh plant communities show signs of recovery within 3 years of oil contamination. Conversely, oiled shorelines that are exposed to high wave energy can accelerate land loss exponentially. Finally, the results demonstrate the value of advanced remote sensing techniques in examining landscape-scale ecosystem changes that are impractical to assess using traditional, field-based quantitative methods.
