West Coast. Biologically Important Areas BIAs are areas and time periods in which cetacean populations are known to concentrate for breeding, feeding, and migration, and areas within which small and resident populations occupy a limited geographic extent. BIAs represent compilations of the best available science and have been used by NOAA, other federal agencies, and the public to support planning and marine mammal impact assessments, and to inform the development of conservation measures for cetaceans.

GIS tools for ecosystem approaches to fisheries management ; Geographic information systems tools for ecosystem approaches to fisheries management ;. Scalable data requirements : Data requirements for sample selection can be as simple as a single polygon outlining the survey area, or as complex as a stratified sample frame with existing sample data and a stratified sample frame for optimally allocating samples.

Random selection : Eliminates sampling biases and corresponding criticisms encountered when samples are selected non-randomly. A random seed number can be entered in the ArcGIS X version. Multiple sampling designs : Simple, stratified, and two-stage sampling designs.

Sample unit-based sampling : Points or polygons are selected from a sample frame. Area-based sampling : Random points are generated within a polygon. And each year, more people flock to our nation's coasts. With them comes more development — new homes, businesses, roads. While this growth enriches the economy, it also places pressure on the environment, potentially diminishing the aesthetic and economic value of living in a coastal area.

NOS works to deliver tools to help balance the health of our coasts with the health of our economy. At NOS, we transform science into practical, innovative tools. For example, the Science Collaborative is a program that puts science conducted at National Estuarine Research Reserves to work in coastal communities. Administered by the University of Michigan, the program supports reserve-led projects that bring together scientists, decision-makers, and educators to address coastal pollution and habitat degradation in the face of climate change.
