This data release includes sampling location data; field-collected stream attribute data; laboratory-analyzed chemistry concentrations (total mercury, methyl mercury) and isotopic composition (total mercury, carbon, and nitrogen) for stream biota (seston, periphyton, benthic insects, emerging adult insects, riparian spiders, and fish); density, body length, and taxonomic information for benthic insects; and density, biomass, and taxonomic information for emerging adult aquatic insects for biota sampled from stream reaches up and downstream of an historical mercury mine site. Sampling took place during summer low-flow conditions in 2015 and 2016. Stream reaches were located on USFS land near the Cinnabar Mine Site...

Description of Work This work will investigate linkages between sediment PCB concentrations and subsequent exposure in riparian organisms living on land next to the river and harbor. This is an extension of prior work at the site that has been used by the Manistique River and Harbor Remediation Team (comprised of managers and scientists from USEPA GLNPO, USEPA ORD, NOAA, USACOE, USGS and the state of Michigan) to guide plans for delisting activities. Riparian spiders are important mediators of contaminant flux from aquatic systems to nearby terrestrial habitats. Aquatic insects accumulate contaminants in their larval form, and transport these contaminants to terrestrial ecosystems in their adult bodies. Spiders...

NEAMAP stands for NorthEast Area Monitoring and Assessment Program. NEAMAP was developed to meet the needs of fisheries management and stock assessment activities in the northeastern United States. NEAMAP began in 2006 with a fall pilot survey and in 2008 began conducting both a spring and fall survey. NEAMAP samples from Cape Cod, MA south to Cape Hatteras, NC and targets both juvenile and adult fishes. NEAMAP is an integrated, cooperative state/federal data collection program. Its mission is to facilitate the collection and dissemination of fishery-independent information obtained in the Northeast for use by state and federal fisheries management agencies, the fishing industry (commercial and recreational),...
