This book was released on 2017-01-04 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the 2017 Robert Cushman Memorial Award presented by the Three Village Historical Society Stony Brook Harbor, or Three Sisters Harbor as it was known historically, is perhaps the most pristine of the Long Island north shore pocket bays. Untouched by major commercialization, it has been designated a Significant Coastal Fish and Wildlife Habitat by the New York State Department of State and a Significant Coastal Habitat by the US Fish and Wildlife Service. Despite these designations, however, there is constant pressure to increase development of and around the harbor. Between Stony Brook Harbor Tides interweaves scientific understandings of the harbor with a consideration of its colorful history to inform and educate a general audience about its unique and delicate state. Data is used to illustrate the harbor's tides and currents and to show how they influence geological processes and pollution susceptibility. Storm surge measurements going back to the early 1990s document some of the extreme high waters experienced, and descriptions of some of the more interesting or important marine species of plants and animals found in the harbor are also included. The book discusses the century-long conflicts that local residents have fought in order to preserve this beautiful place, and it documents the tools that currently exist to help manage the harbor well into the twenty-first century. An excellent supplement to any high school or undergraduate environmental course, Between Stony Brook Harbor Tides provides readers with a basis for embracing the significance of the harbor and what it can bring to future residents.

This book was released on 2014 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Overdevelopment of coastal areas leads to salt marsh deterioration, hindering its ability to regulate sea level rise, wave energy, and storm events. This study assesed marsh change and the potential impacts of Huricane Sandy on salt marsh at Milford Point, extending the work done by Stephen Jonas (2004) and Justin Goggins (2010). in conclusion, the hurricane had a positive impact on marsh vegetation development and growth.

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.

This book was released on 2019 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Change in the coastal zone is accelerating with external forcing by sea-level rise, nutrient loading, drought and over-harvest is impacting salt marshes. Understanding marsh resilience, including recovery from coastal storms and detection of stress, is essential for conservation and prediction of ecosystem services. The ‘chronosequence approach’ of predicting future state change by examining ecosystem structure and function in existing ecosystems of different ages is a powerful tool, but assumes that the past mimics the future, and time is the dominant driver of change. This approach was evaluated by replicating a 1995 salt marsh chronosequence study in back-barrier marshes ranging from 4 to >170 yr old on Hog Island, Virginia. Physico-chemical properties, such as porewater redox potential and sediment organic matter and nutrients, followed predictable age-related patterns. However, invertebrate abundance, plant biomass, and sediment grain size instead seemed to respond to sea level rise and stochastic die-off and sand deposition. Thus, while time drives the intrinsic evolution of some physico-chemical components, extrinsic drivers exert a strong influence on key biotic-abiotic feedbacks. Exacerbation of external forcing may push the trajectory of marsh succession away from a predictable trajectory, limiting ecosystem services. This rapid evolution of marsh state makes the ability to detect stressors prior to marsh collapse important. Hyperspectral imagery of plants was collected in marshes of varying age/stressor characteristics, including salinity, sediment redox potential and nitrogen availability, and in the greenhouse, where environmental conditions were manipulated. Models developed to stressors based on plant spectral response were useful for salinity and nitrogen within the greenhouse or within the field, but were not transferable from lab to field. This study is an important step towards development of a remote sensing tool for tracking of ecosystem development, marsh health, and future ecosystem services."--Abstract.
