Abstract Since the late nineteenth century, channel depths have more than doubled in parts of New York Harbor and tidal Hudson River, wetlands been reclaimed navigational channels widened, river flow has regulated. To quantify effects these modifications, observations numerical simulations using historical modern bathymetry are used to analyze changes barotropic dynamics. Model results water level records for Albany (1868 present) (1844 recovered from archives show that amplitude near head...
Abstract Tidal wetlands produce long-term soil organic carbon (C) stocks. Thus for accounting purposes, we need accurate and precise information on the magnitude spatial distribution of those We assembled analyzed an unprecedented core dataset, tested three strategies mapping stocks: applying average value from synthesis to mapped tidal wetlands, models fit using empirical data applied soil, vegetation salinity maps, relying independently generated maps. Soil stocks were far lower varied...
[1] An observational study was conducted to identify mechanisms of suspended sediment flux and turbidity maintenance in the Delaware River estuary. From March through October 2005, instrumented moorings were deployed obtain continuous measurements currents concentration at sites along estuarine channel on flanking subtidal flats. Data time series analyzed determine relative influence nontidal advection tidal pumping residual fluxes sediment. Results indicate that is a strongly advective...
Abstract. Carbonate geochemistry research in large estuarine systems is limited. More work needed to understand how changes land-use activity influence watershed export of organic and inorganic carbon, acids, nutrients the coastal ocean. To investigate seasonal variation carbon system Delaware Estuary, one largest estuaries along US east coast, dissolved (DIC), total alkalinity (TA), pH were measured estuary from June 2013 April 2015. In addition, DIC, TA, periodically March October 2015...
Abstract Lateral processes contribute significantly to circulation and material transport in estuaries. The mechanisms controlling may vary spatially such that shallow deep regions of an estuary differently the total transport. An observational study was conducted explore importance lateral variability sediment Delaware Estuary. Seven moorings were deployed across channel region estuarine turbidity maximum (ETM) zone from April August 2011. Time series along‐channel reveal a consistent...
ABSTRACT We present an expanded training set of salt‐marsh foraminifera for reconstructing Holocene relative sea‐level change from 12 sites in New Jersey that represent varied physiographic environments. Seven groups are recognized, including four high‐ or transitional‐marsh assemblages and a low‐salinity assemblage. A weighted‐averaging transfer function trained on this dataset was applied to dated core Barnegat Bay reconstruct sea level with uncertainties ± 14% tidal range. evaluate the...
