Accumulation of sediment and radionuclides in tidal marshes of the Murderkill River Estuary, Delaware
… patterns and rates of sediment accumulation and tidal marsh accretion in the Murderkill River estuary, Delaware, with special emphasis placed on changes in accumulation rates and sediment physical properties associated with historical land-use practices, such as mosquito ditching. Over 90% of …

VARIATION, ADAPTATION AND REPRODUCTIVE BIOLOGY IN RUPPIA MARITIMA L POPULATIONS FROM NEW HAMPSHIRE COASTAL AND ESTUARINE TIDAL MARSHES
… maritima L. populations in coastal and estuarine tidal marshes in New Hampshire exhibit considerable variation in morphology, reproductive strategy and pollination ecology in response to a range of environmental conditions. Variation among the populations correlates with seasonal changes in …

Observations on the Life History of the Bayou Killifish, <i>Fundulus pulvereus</i> (Everman 1899) in Mississippi Tidal Marshes
… the life history of the relatively unknown intertidal marsh fish <em>Fundulus pulvereus</em> (Everman), the bayou killifish. Monthly sampling for <em>F. pulvereus</em> took place in three different Mississippi tidal marshes over a period of 17 months (n=445). Observations on the diet, parasite …

Towards Characterisation and Classification of Canadian Macrotidal Salt Marshes
… the extent, distribution, and condition of tidal marshes in Canada, they have yet to be comprehensively mapped. Existing inventories show significant overestimation of Canadian tidal marsh extent, indicating that a regional model may be required. This thesis provides a review of freely …

Tidal Wetland Inundation and Vegetation Phenology from Space: A Synthesis of Approaches for Characterizing Ecological Status and Inundation Dynamics in Tidal Wetlands with Remote Sensing Observations
… on the monitoring and characterization of tidal marshes using remote sensing-based approaches. Chapter 1 introduces the topics of wetland ecology and remote sensing. Chapters 2-4 are the main research chapters of the dissertation covering the topics of tidal marsh mapping, tidal marsh …

Topophilia: A Tidal Retreat
… of the latter in its specificity of place, the tidal marshes and sea islands of the Carolinas. How do we come to know a place? What is the significance of one's participatory perception of the qualitative experience of the natural world? How can that awareness of the specificity of the …

Plant-habitat interactions in brackish marshes
Estuarine marshes are ecosystems that are situated at the transition zone between land and water and are thus controlled by physical and biological interactions. Marsh vegetation offers important ecosystem services by filtrating solid and dissolved substances from the water and providing habitat. …

Sedimentary Characteristics of an Estuarine Marsh System and the Roles of Storm Overwash, Micro-tidal Currents, and Organic Production: Big Branch Marsh, Louisiana
… to discern the relative influences of fluvial, tidal, and storm overwash transport dynamics of a micro-tidal estuarine marsh system. Collected sediment samples from tidal channel beds, pond bottoms, and marsh surfaces were analyzed for organic content and particle-size distribution. Parameters …

Examining UAV-based LiDAR, Multispectral, Hyperspectral and Precision Photogrammetry Approaches for Tidal Salt Marsh Environments
Tidal salt marshes are one of the most productive and valuable ecosystems on Earth, providing multiple ecosystem services such as blue carbon trapping and coastal flood mitigation. However, this ecosystem is under serious threat due to human activities and rising sea levels. The purpose of this …

Capturing dynamics of marine inorganic carbon fluxes from diurnal to decadal timescales
… fluxes across different boundaries, such as tidal exchange between coastal wetlands and coastal oceans. Coastal salt marshes have been suggested to be a large net CO2 sink, thus designated as a type of “blue carbon.” However, accurate and dynamic estimates of carbon fluxes to and from tidal …

Predicting Plant Zonation in the Salt and Brackish Marshes of Georgia
<p>Tidal marshes provide important economic and environmental functions. There are 1,745 km<sup>2</sup> of tidal marsh habitat along the Georgia coast that can be separated into three distinct marsh types based on salinity levels. Tidal fresh, brackish, and salt marshes occur along a gradient that …

Multiproxy Analyses of Past Vegetation, Climate, and Sediment Dynamics in Hudson River Wetlands
… Hudson River from Troy, NY to New York Harbor is tidal and is considered an important estuary. Tidal marshes are especially important for their roles in carbon sequestration, water filtration, primary production, flood-zone buffering, fisheries, and recreation. However, these valuable ecosystems …
