Evaluation of streamwater quality in the Atlanta region Evaluation of streamwater quality in the Atlanta region
A water-quality index (WQI) was developed from historical data for streams in the Atlanta region. The WQI was derived from percentile ranks of individual water-quality parameter values at each stream by normalizing the constituent ranks for values from all sites in the area for the period from 1990 to 1995. WQIs were developed primarily for nutrients and nutrient-related parameters...

A science-based, watershed strategy to support effective remediation of abandoned mine lands A science-based, watershed strategy to support effective remediation of abandoned mine lands
A U.S. Geological Survey Abandoned Mine Lands Initiative will develop a strategy for gathering and communicating the scientific information needed to formulate effective and cost-efficient remediation of abandoned mine lands. A watershed approach will identify, characterize, and remediate contaminated sites that have the most profound effect on water and ecosystem quality within a...

Aerial videography for estimating goose populations staging in Izembek Lagoon, Alaska Aerial videography for estimating goose populations staging in Izembek Lagoon, Alaska
We conducted experimental photographic surveys of black brant and Canada geese in a pre-migration staging area on the Alaska Peninsula to compare precision and efficiency of this technique to currently employed ocular estimates. Video and digital cameras sensitive to near infrared and visible radiation were tested at various altitudes and with lenses of different focal length. Using...

Amplitude versus offset modeling of the bottom simulating reflection associated with submarine gas hydrates Amplitude versus offset modeling of the bottom simulating reflection associated with submarine gas hydrates
A bottom simulating seismic reflection (BSR) that parallels the sea floor occurs worldwide on seismic profiles from outer continental margins. The BSR coincides with the base of the gas hydrate stability field and is commonly used as indicator of natural submarine gas hydrates. Despite the widespread assumption that the BSR marks the base of gas hydrate-bearing sediments, the occurrence...
