This dataset consists of measurements of the digestive gland in the freshwater snail Lymnaea stagnalis orally exposed to uranium. The objective of the study was to assess the morphological effects of uranium on the snail digestive gland by light microscopy. Laboratory-cultured L stagnalis were exposed to either synthetic or natural solid phases of uranium and a subset (6 controls and 6 exposed) were euthanized and fixed in 10% neutral buffered formalin for histopathological assessment. Slides were processed and stained with hematoxalin and eosin as per standard procedure (Luna 1968). The size of each sample, the length and width of digestive gland tubules (5 random glands per sample) and height of digestive cells...

This dataset contains field measurements of lakebed groundwater temperatures collected during three surveys in July 2008, August 2014, and August 2015, by using a handheld thermocouple probe and GPS at a permeable reactive barrier at Ashumet Pond, Falmouth, MA. The comma-separated file includes unique site identifiers, locations of measurement points, temperatures, dates, and types of measurement (groundwater, surface water, or control). Also included are ESRI raster datasets for each measurement date for (1) interpolated lakebed groundwater temperatures, and (2) interpolated lakebed groundwater temperatures normalized to the surface water temperature at the time of measurement. This data release is provided...

Coastal communities are uniquely vulnerable to sea-level rise (SLR) and severe storms such as hurricanes. These events enhance the dispersion and concentration of natural and anthropogenic chemicals and pathogenic microorganisms that could adversely affect the health and resilience of coastal communities and ecosystems in coming years. The U.S. Geological Survey has developed the Sediment-Bound Contaminant Resiliency and Response (SCoRR) strategy to define baseline and post-event sediment-bound environmental health (EH) stressors. These data document toxicity measured by reduction of the light emission of Aliivibrio (formerly Photobacterium) fischeri and the inhibition of polymerase chain reactions caused by environmental...
