USGS Scientists Collect Water Quality Samples in the San Francisco Bay
USGS scientists collect water quality samples in the San Francisco Bay. The samples have been collected at the same locations for >50 years and are part of one of the longest running datasets of its kind in the United States. Sampling extends from the South San Francisco Bay at the Dumbarton bridge and ends in the Delta waterways in Antioch. Cruise days can last upwards
