Vegetation percent cover data along transects through a nutrient enriched marsh receiving wastewater effluent and a reference (unenriched) marsh. Nutrient enrichment comes from the Ipswich Wastewater Treatment Facility on Greenwood Creek in Ipswich.  The marsh around Clubhead Creek, Rowley, MA was used as a reference.

Five transects were laid out in along Greenwood Creek .  These varied in length from 25 through 50 m and started at edge of marsh creek and ran perpendicular to upland..  Two transects along Clubhead Creek were the same ones used as reference for the haying study.  These are about 150 m long.  0.2x1m quadrats placed down at 5m intervals along transect lines at Greenwood and 10 m intervals at Clubhead Creek.   Percent covers are estimated visually and are based on the entire area within the quadrat including non vegetated areas. Absolute and % covers can then be calculated for each transect.  NOTES AND COMMENTS: Names of observers: RB (Robert Buchsbaum), HG (Hap Garritt, HH (Heather Haas), and JL (John Logan).  If a percent cover was judged to be <1%, it was entered as 0.001 decimal fraction on the spreadsheet.

An important but neglected linkage between land and coastal waters is the input of dissolved and particulate organic carbon and organic nitrogen. This long-term ecological research (LTER) in land/ocean margin ecosystems will focus on the following question and hypotheses: How will trophic structure and primary and secondary productivity in estuaries be affected by changes in organic matter, nutrient and water fluxes cause by changing land cover, climate and sea level? Hypothesis 1. The interaction of inorganic nutrients with the quantity and quality of organic carbon and organic nitrogen plays an important role in determining the trophic structure, production and efficiency of estuarine food webs. Hypothesis 2. The variability in land, ocean and atmospheric forcing is a key component determining the fate of allochthonous and autochthonous materials and the location and magnitude of primary and secondary production.
