ENVIRONMENTAL STATISTICIANS
 OUTREACH TO THE STATES and TRIBES
 ADMINISTRATIVE REQUIREMENTS

EPA’s REQUEST FOR APPLICATIONS
(RFA) - continued
 MAJOR ADMINISTRATIVE REQUIREMENT
 “… EACH OF THE TWO PROGRRAMS
ESTABLISHED WILL INVOLVE COLLABORATIVE
RESEARCH AT MULTIPLE, GEOGRAPHICALLY
DIVERSE SITES.”
 CLOSE COOPERATION BETWEEN TWO
PROGRAMS
 SPECIFICALLY TO AVOID DUPLICATION OF EFFORT
 ===> JOINT ANNUAL MEETING ++

 HAVE POST-DOCS AND PRE-DOCTORAL STUDENTS
CONDUCT RESEARCH ON THESE TOPICS

 FACULTY TIME
~ 1 FTE (12M)
 OTHER
 SUBCONTRACT TO OSU
~ $120K
 COMPUTING EQUIPMENT - ONE TIME =$20K

AMPLE
# 15
OSU COMPANION PROPOSAL
 SIMILARILY STRUCTURED
 MAJOR DIFFERENCE = FOCUS
 DESIGN-BASED/MODEL ASSISTED
 OSU SUBCONTRACT TO CSU THE SAME
SCALE AS CSU SUBCONTRACT TO OSU
 BOTH PROGRAMS HAVE OTHER
SUBCONTRACTORS THE FIRST YEAR

WHAT IS DISTINCTIVE ABOUT’
“AQUATIC RESOURCES”?
 THEY ARE THINGS LIKE
 STREAMS
 RIVERS
 WETLANDS
 LAKES & PONDS
 ESTUARIES
 PRAIRIE POTHOLES
 NEAR COASTAL OCEANIC WATERS
# 17
WHAT IS DISTINCTIVE ABOUT’
“AQUATIC RESOURCES”?
CONTINUED
 FOR MOST AQUATIC RESOURCES,
 THERE ARE MANY “SMALL” ONES
 PROGRESSIVELY FEWER AS THEY GET BIGGER
 INTEREST, BIOLOGICAL & SOCIETAL, TENDS TO
STAY CONSTANT OR EVEN INCREASE WITH SIZE
 SIMPLE RANDOM SAMPLING WOULD SELECT
MOSTLY “SMALL” ONES, FEW BIG ONES.
 IMPLICATION:
 UNEQUAL PROBABILITY SAMPLING
# 18
WHAT IS DISTINCTIVE ABOUT’
“AQUATIC RESOURCES”?
CONTINUED II
 SPATIAL STATISTICS TENDS TO FOCUS ON
TWO-DIMENSIONAL SPACE
 STREAMS AND RIVERS ESSENTIALLY AMOUNT
TO ONE-DIMENSIONAL OBJECTS IN TWO-SPACE
 BUT MUCH LANDSCAPE INFORMATION IS
COMPLETE COVERAGE IN TWO-SPACE
 CHALLENGE:
 MERGE THESE PERSPECTIVES
# 19
DISTINCTIVE EMAP PERSPECTIVE
 DEFINE THE POPULATION OF INTEREST
 CONDUCT A PROBABILITY SURVEY OF IT
 CAREFULLY DEFINE THE SAMPLING FRAME
 VARIABLE PROBABILITY SELECTION OF SITES, BUT
WITH SPATIAL BALANCE
 CAREFULLY DEFINE RESPONSES TO BE EVALUATED
 TRAIN FIELD CREWS WELL
 MANAGE DATA WITH CARE AND AN “AUDIT TRAIL”
 LEARN FROM PAST MISTAKES, THROUGHOUT
 SEE A FEW ILLUSTRATIONS
 DATA SETS TO BE USED
# 20
AN EMAP STUDY: NORTHEAST LAKES
SAMPLING MODEL - DISCRETE
 TWO STEP SELECTION PROCESS
 FIRST STEP = SPATIALLY SYSTEMATIC
 EMAP = 1/64 EACH YEAR
 FOUR YEARS ===> 1/16 AREA SAMPLE
 SECOND STEP = PROBABILITY
 INCLUSION PROB VARIED BY LAKE SIZE CLASS
 SPATIAL RESTRICTION - MILD
 CAN BE DESCRIBED FOR INTERESTED PEOPLE
 TIME ESSENTIALLY THE SAME, EXCEPT AN
ADDITIONAL 2/64 EXTRACTION WAS DONE
 ONLY IN ITS AREAS OF INTEREST

DISTINCTIVE EMAP PERSPECTIVE
CONTINUED
 IF DISCIPLINES LACK TOOLS, SUPPORT
DEVELOPMENT OF THEM
 STATISTICS INCLUDED
 EXAMPLE: EXTEND CONCEPTS OF SAMPLING FROM
FINITE POPULATION TO SPATIALLY CONTINUOUS
POPULATIONS
 NATIONAL RESEARCH CENTER FOR STATISTICS AND THE
ENVIRONMENT (~ $1M/YEAR)
 UNIVERSITY OF WASHINGTON PAST 5 YEARS
 NOW TO BE AT UNIVERSITY OF CHICAGO
 TWO PROGRAMS UNDER DISCUSSION HERE
# 28
FUTURE NEEDS - STATES & TRIBES
 STATES AND TRIBES MUST REPORT ON THE
CONDITION OF ALL “WATERS” UNDER
THEIR JURISTICTION
 A REQUIREMENT OF SECTION 305b OF THE
CLEAN WATER ACT
 RESULTS IN BIANNUAL REPORT TO CONGRESS
 STARTING IN 2004 NEW RECOMMENDED
STANDARDS WILL REQUIRE THESE BE
BASED ON PROBABILITY SAMPLING
# 29
FUTURE NEEDS - STATES & TRIBES
CONTINUED
 PROJECT # 4 WILL HELP
 IDENTIFY NEEDED SKILLS IN THE STATES &
TRIBES
 DEVELOP THE NEEDED SKILLS
 IF POSSIBLE, WE HOPE TO TRANSMIT THE
LEARNING MATERIALS IN WEB-COMPATIBLE
DOCUMENTS
 RECORDED ON A CD ROM USABLE AT ANY
REMOTE SITE
# 30
PROGRAM NEEDS from THIS LAB
 INPUTS ON LANDSCAPE PERSPECTIVES
 REAL “COOPERATION”
 ACCESS TO EXISTING RELEVANT GIS
COVERAGES
 SHORT TERM: MAHA/MAIA
 COVERAGES
 PRIMARY REMOTELY SENSED DATA
