This datalayer is part of a group of layers used for research in the Ipswich River Watershed. This datalayer is a mask of the area within the towns that make up the Ipswich River Watershed study area. The area on this mask is the complete town area of each town, and as such includes areas that are not actually within the watershed. This map has full information and was derived from the “ip30_noinfo_townmask” image. To be used to maske out area not within any town within the Ipswich River Watershed.

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.
