Salt Marsh Tidal Channels
Salt marsh tidal channels are highly sinuous. For this project, field surveys and aerial photographs were used to characterize the planform of tidal channels at China Camp Marsh in the San Francisco Bay, California. To model the planform evolution, we assume that the topographic curvature of the channel centreline is a key element driving meander migration. Extraction of curvature data from a p...
متن کاملMicrobial Community Analysis of a Coastal Salt Marsh Affected by the Deepwater Horizon Oil Spill
Coastal salt marshes are highly sensitive wetland ecosystems that can sustain long-term impacts from anthropogenic events such as oil spills. In this study, we examined the microbial communities of a Gulf of Mexico coastal salt marsh during and after the influx of petroleum hydrocarbons following the Deepwater Horizon oil spill. Total hydrocarbon concentrations in salt marsh sediments were high...
متن کاملPhylogenetic diversity of Archaea in sediment samples from a coastal salt marsh.
The Archaea present in salt marsh sediment samples from a tidal creek and from an adjacent area of vegetative marshland, both of which showed active methanogenesis and sulfate reduction, were sampled by using 16S rRNA gene libraries created with Archaea-specific primers. None of the sequences were the same as reference sequences from cultured taxa, although some were closely related to sequence...
متن کاملAnalyzing the Long-Term Phenological Trends of Salt Marsh Ecosystem across Coastal LOUISIANA
In this study, we examined the phenology of the salt marsh ecosystem across coastal Louisiana (LA) for a 16-year time period (2000–2015) using NASA’s Moderate Resolution Imaging Spectroradiometer’s (MODIS) eight-day average surface reflectance images (500 m). We compared the performances of least squares fitted asymmetric Gaussian (AG) and double logistic (DL) smoothing functions in terms of in...
متن کاملCarbon isotope ratios of methyl bromide and methyl chloride emitted from a coastal salt marsh
[1] Methyl bromide (CH3Br) and methyl chloride (CH3Cl) play important roles in stratospheric ozone depletion, but their atmospheric budgets have large uncertainties. The analysis of stable isotope composition of methyl halides may provide useful independent information for further constraining their budgets. Here we report the first measurements of CH3Br and CH3Cl stable carbon isotope ratios e...
