The data presented are the results of sampling in estuaries in the North Carolina portion of the EMAP Carolinian Province during summer 1994-96. A total of 135 randomly located stations was sampled according to a probabilistic sampling design, and included measurements of: l)general habitat condition (depth, physical properties of water, sediment grain-size, organic carbon content), (2) pollution exposure (sediment contaminant concentrations, sediment toxicity, low dissolved oxygen conditions in the water column, ammonia and sulfide in sediment porewater), (3) biotic conditions (diversity and abundance of macroinfauna), and (4) aesthetic quality (presence of anthropogenic debris, visible oil, noxious sediment odor, water clarity). The first section of the report presents summary information on station locations, general physical characteristics of the estuaries and levels of selected environmental variables, sediment contaminant concentrations and sediment toxicity, and taxonomic composition of benthic macroinfaunal communities. Figures comparing results for all three years (1994-96) are included for infaunal richness, H' diversity, and abundance; condition of macroinfaunal assemblages based on the Benthic Index of Biotic Integrity (IBI); and sediment quality based on combined measures of sediment contamination, toxicity, and in-situ macroinfaunal conditions. Appendices accompanying this report include means and ranges of parameters listed by station for all sites sampled in North Carolina during summer 1994-96. These results also include non-random, supplemental sites chosen based on some prior knowledge of the ambient environmental conditions in those areas. Supplemental sampling sites were not included in any calculations used to develop the tables and figures presented in the first section of the report. This report represents a final data summary, and as such is purely descriptive in nature. However, these data will be used in combination with 1997 data to prepare a manuscript for publication, which will include more detailed analyses and interpretations for the overall four- year period (1994-1997). The complete database in electronic form is being provided to the EMAP Carolinian Province Office Manager, and is also available online through the EMAP web site at http://www.epa.gov/emap/.

In the EMAP station number, RR = Large Tidal River, RP = Large Tidal River Replicate, SR = Small Estuary, SP = Small Estuary Replicate, and LR = Large Estuary. In area column, R = Replicate Station and NA = Not Applicable. Area refers to area of estuary (for small estuaries), area of river segment (for large tidal rivers), or area of grid cell (for large estuaries). 5 Table 2.
