Impact/Purpose:

Our objectives for this Program are to extend existing EMAP survey design and analysis methodology to enhance the use of auxiliary information; to develop design-based model-assisted methodology compatible with EMAP's multi-tiered studies; to implement these techniques on example data sets; to provide expert survey design and analysis assistance to States and Tribes; and to transfer that statistical expertise to States and Tribes through a combination of supervised application of statistical tools and structured distance learning techniques.

Description:

We expect to accomplish five major goals with the Program. The first is to extend design-based statistical methodology to cover the unique circumstances encountered in EMAP. The second is to make both existing and newly-developed model-assisted design-based statistical tools more accessible to State and Tribe personnel, both the aquatic scientists and managers of aquatic resources. The third is to expand the pool of personnel in the States and Tribes who have both understanding of and experience in using the statistical tools. The fourth is to develop a cadre of statisticians with the experience and expertise to collaborate on monitoring aquatic resources. Finally, we will develop three archetypes of rigorous probability-based, state or local monitoring programs, along with archetype design-based, model-assisted analyses. The existence of these archetypes will benefit EMAP's efforts to build state, tribal, and local infrastructure to monitor the condition of the Nation's aquatic resources.

Approach :

Our approach will be to initiate statistical research on several well-defined topics in model-assisted estimation: non-parametric model-assisted design-based estimation, estimation and prediction using empirical orthogonal functions on probability survey data, model-assisted imputation, model-assisted survey design, and analysis of multi-year panel studies. We have made preliminary contacts with some State and Tribal agencies who have a connection to EMAP. We will strengthen and expand those contacts to include all identifiable State and Tribal agencies who are using (or plan to use) EMAP, REMAP, or EMAP-like surveys of aquatic resources. We will assist those agencies in applying existing survey design and analysis methods, and, in particular, investigate and extend techniques for incorporating auxiliary information in the design. In collaboration with those agencies and other State and Tribal organizations, we will identify further statistical research needs to be addressed by our statistical methodology research teams.

Three state agencies (Oregon Department of Fish and Wildlife (ODFW), California State Water Resources Control Board (CSWRCB), and the San Francisco Estuary Institute(SFEI)) which have existing or planned aquatic monitoring programs that use EMAP's sampling methodology have a special role. These agencies will identify areas where our statistical expertise will be especially beneficial and act as "laboratories" for testing distance learning methods. They will provide guidance on the areas where they feel they need more knowledge; we will structure the content and delivery method to meet those needs; and they will provide feedback and critique.

The interaction between these three agencies and this Program has the potential to develop into model archetypes for state and local level monitoring programs. The three programs represent a microcosm that spans almost all of the circumstances t
