Sulfate deposition to high-elevation areas has decreased here as a result of reductions in SO2 emissions. Nitrate deposition did not change, whereas ammonium deposition increased, particularly at sites near urban and agricultural areas.
We assess the degree to which a consensus was reached on the flow rate of the well by comparing in situ observations with a time-dependent flow rate model derived from pressure readings taken after the Macondo well was shut in for the well integrity test.
Locations of survey points, a photographic record of each site, field observations of vegetation cover and descriptions of oil coverage in the water and on plants, including measurements of the distance of oil penetration from the shoreline.
Description of the Status and Trends program, which monitors the abundance, distribution, productivity, and health of the Nation's living resources, detecting and evaluating changes in these variables over time.
