Field Activity D175EG

Identifier D175EG
Alternate names D-1-75-EG,EGAL-75-GB
Purpose To: 1) provide comprehensive environmental and biological data and information on the Alaska Outer Continental Shelf lease area; 2) define the probable ecological impact of oil exploration, production, storage, and trans-shipment on the OCS; 3) refine our understanding of key ecological dynamic processes; and 4) provide a basis for a priori predictive or diagnostic models of the eco-system response to leading by petroleum and petroleum by-products. To measure suspended sediments, light hydrocarbons, chlorophyll content, primary productivity, turbidity, nutrients, lithology, incident light measurements, light penetration values in euphotic zones, marine mammal and bird observations.
