Subtopics:
Capturing (animals) (3 items)
Drilling and coring (10 items)
Specimen collecting (3 items)
Transect sampling (2 items)
Trenching (1 items)
Water sampling (5 items)

Environmental impact of the Contact and Sonoma mercury mines on water, sediment, and biota in Anna Belcher and Little Sulphur Creek watersheds, Sonoma County, California [New Window]
Data from field sampling of tailings, waste rock, sediment, and water at the mines, along with water, sediment, and biota in a pond and tributaries that drain from the mine area, to help assess the chemical hazards due to historic mining.
Environmental impact of the Helen, Research, and Chicago mercury mines on water, sediment, and biota in the Upper Dry Creek watershed, Lake County, California [New Window]
Data from field sampling of tailings, waste rock, sediment, and water at the mines, along with water, sediment, and biota in a pond and tributaries that drain from the mine area, to help assess the chemical hazards due to historic mining.
