Temporal and spatial variation in methyl bromide emissions from a salt marsh
Methyl bromide (CH3Br) is a trace gas involved in stratospheric ozone depletion with both anthropogenic and natural sources. Estimates of natural source strengths are highly uncertain. In this study, >320 highly temporally and spatially resolved measurements of CH3Br emissions from a salt marsh in Scotland (56o00 N, 2o35 W) were made during one year using eight static enclosures. Net emissions ...
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...
متن کاملTemporal and spatial relationships between watershed land use and salt marsh disturbance in a pacific estuary.
Historical and recent remote sensing data can be used to address temporal and spatial relationships between upland land cover and downstream vegetation response at the watershed scale. This is demonstrated for sub-watersheds draining into Elkhorn Slough, California, where salt marsh habitat has diminished because of the formation of sediment fans that support woody riparian vegetation. Multiple...
متن کاملAnalysis of Temporal and Spatial Phytoplankton Variability in a Long Island Salt Marsh
A study of phytoplankton and related variables in a Long Island salt marsh was designed to incorporate three major sources of variation in the sampling regime: spatial, short-term temporal, and long-term temporal. The combination of multivariate (MANOVA and factor analysis) and univariate (ANOVA) data analyses was used to examine the relative importance of each source of variation in 11 variabl...
متن کاملTemporal and spatial variability of vertical salt flux in a highly stratified estuary
[1] The temporal and spatial variability of vertical salt flux in the Fraser River Estuary, British Columbia, was investigated observationally, using several different direct and indirect indicators of buoyancy flux. Data were collected from the estuary using shipboard instrumentation, primarily an acoustic Doppler current profiler and a towed conductivitytemperature-depth unit. Direct estimate...
