“…Evidence from some studies of detritus and carbon in tidal creeks supports the view that there is a net seasonal loss from coastal marshes into the sea (Odum & De La Cruz 1967;Nixon & Oviatt 1973), but a study of a brackish estuary found no net export (Heinle & Flemer 1976), and Woodwell et ale (1977) argue that some coastal marshes are net sinks for carbon.…”

“…Some measurements were made in other estuaries, but it seems to depend strongly on the geography and hydrography of the area and on the type of vegetation, whether one or the other factor is more important. Teal (1962), Nixon & Oviatt (1973) and Heinle & Flemer (1976) have found that between 45 and less than 1 ~ of the marsh production was transported to the adjacent estuaries.…”

During 1975, measurements were made to quantify all sources of input of organic matter in the Dollar& This made a comparison possible between in situ primary production, import from natural sources and organic waste discharges in terms of organic carbon. In order to make a carbon budget, mineralization and the amount of organic matter buried in the sediment was also measured. Input of organic carbon was mainly based on primary production on the tidal flats (measured in situ as 02 production, 9.3 )< 106 kg C 9 year-*), accumulation of suspended matter originating from the North Sea and the River Eros (maximal 37.1 • 106 kg C 9 year -~) and discharge of heavily polluted water (33.0 • 106 kg C 9 year-l). Input from primary production in the water phase was negligibly low (0.7 • 10" kg C 9 year-*). Loss of organic carbon was due to mineralization in the sediment (measured in situ as oxv~.en consumption, 18.2 • 106 kg C 9 year-i), mineralization in the water phase (using the BOD technique, 7.2 • 106 kg C 9 year-*) and burying of organic matter in the sediment (9.9 • 106 kg C 9 year-*). The loss of dissolved organic matter to the adjacent Waddensea was not measured but must be considerable. Allochthonous detritus was the main source of energy for the foodwebs in the Dollar& The role of bacteria as an important source of food for higher organisms in the Dollard is discussed.

“…[3] In tidal areas, hydrology at least partially controls the exchange of nutrients, organic matter, and pollutants between upland watersheds, tidal wetlands and surface waters [Gardner, 1975;Heinle and Flemer, 1976;Valiela et al, 1978;Luther et al, 1982;Hemond et al, 1984;Jordan and Correll, 1985;Yelverton and Hackney, 1986].…”

[1] Wetland restoration efforts are ongoing in many urban estuaries. In this context the hydrologic characteristics of restored wetlands are of paramount importance since the spatially and temporally variable position of the water table and of soil saturation establishes the oxidation state of the substrate, which, in turn, affects the wetland's biogeochemical composition and the biological communities it is capable of supporting. A relatively simple analytical model developed here describes tidal marsh hydrology from creek bank to interior, considering transient drainage, net meteorological inputs, and tidal effects. Given a series of physical and time-dependent inputs, the analytical solution derived predicts the position of the water table at points along a transect perpendicular to a tidal creek. Validation of the model using water table time series data collected along three transects at Piermont Marsh, a tidal wetland on the Hudson River in the New York/ New Jersey Estuary, indicates good general agreement between observations and predictions, although it may not be precise enough for some kinds of ecological applications. A sensitivity analysis on the model indicates that a range of pairs of transmissivity and specific yield values that increase with distance from the creek results in the same spatial and temporal fluctuations in the water table. This equifinality result is discussed as it relates to the predictive capacity of the model presented.
