Hudson River estuary

In more recent studies, Feng et al. (1999) calculated a Th water column residence time of 2 to 12 days in the Hudson River estuary. McKee et al (1986b) determined that " Th was removed on a time scale of a day or less in the very particle-rich environment of the Yangtze River estuary. In the Amazon River estuary, another particle-rich environment, McKee et al. (1986a) determined that the residence time of dissolved " Th ranged from 2 to 4 days. McKee et al. (1986a) also calculated apparent distribution...

The first scientists to investigate the coastal atmospheric presence of APs were Van Ry and Dachs, in a study conducted in the Hudson river estuary. GC-MS analyses showed that atmospheric NP isomer mixtures have a similar composition to technical mixtures, with relatively high total concentrations in the range of 0.0002—0.069 xg m-3 in the gas phase, and 0.0001-0.051 p,gm-3 in the aerosol phase. These concentrations are higher than those of polycyclic aromatic hydrocarbons and up to two orders of magnitude higher than polychlorinated biphenyl concentrations in impacted urban-industrial areas [32].

Some of the earliest work on Rn in estuaries indicated that an enrichment in Rn in pore waters occurred from Rn recoil from solids and its overall inert natural character (Hammond et al., 1977). This work in the Hudson River estuary (USA) also concluded... 

Figure 13.20 Temporal variation in CO2 fluxes at three stations in the Hudson River estuary. Positive values represent production of CC and negative values are consumption. CO2 consumption represents the sum of net primary production (NPP) integrated over the photic zone and dark assimilation integrated over the surface mixed layer. Error bars represent 1 standard deviation. (Modified from Taylor et al., 2003.)...
