SFEI LOOKING BACK : LOOKING FORWARD The RMP has always been composed of a diverse (odd ?) set of individuals
SCIENTISTS
ENGINEERS
INDUSTRY
ENVIRONMENTALISTS
SUMMARY FIRST RMP ANNUAL MEETING “IT’S BEEN A LOVE FEST” (Steve Ritchey: SF RWQCB)
15 YEARS LATER SF BAY : NATIONAL MODEL (Sañudo-Wilhelmy et al., Environmental Science & Technology)
THE PROBLEM - ELSEWHERE Literature Survey metals in US estuaries Results only 83 published articles no data ~ 1/2 US estuaries Only long term metal studies SF Bay Most studies in other estuaries being done by RMP alumni Sañudo-Wilhelmy et al., 2004
RMP ALUMNI * CONDUCTING ESTUARINE STUDIES ELSEWHERE East Coast: Sergio Sañudo *Stony Brook Mark WellsMaine Greg Cutter *ODU John DonatODU Gulf Coast: Gary Gill *Texas A&M Bill LandingFlorida State Far East Coast: Kuria Ndung’u *Sweden * still involved in SF Bay-Delta studies * incomplete listing
RMP ALUMNI * REGULATING ESTUARINE STUDIES Priya GanguliSF RWQCB Peter KozelkaUS EPA Jon PhinneyNOAA Ignacio RiveraUS Navy Doug StedingSupreme Court* * incomplete listing * circa 2010

MERCURY IN SF BAY SFEI Summary Time Series Data
OTHER PROBLEMS WITH SF BAY Physical Complexity Hydrologic Complexity
RMP DATA QUANTIFY TEMPORAL CHANGES Ag & Pb in the South Bay ( ) Dissolved Ag: 40% decline Dissolved Pb: no decline Total Ag: 70% decline Total Pb: 40% decline Squire et al., ES&T
RMP DATA ENABLE PROJECTIONS Cooke et al., URS & Monismith et al., Stanford Schubel et al., 2003
RMP DATA MODEL LIMITATIONS Small data set Limited spatial coverage Assumptions of constancy in an inconstant world Flegal et al., 1991 It is safer to interpolate than extrapolate It is safer to interpolate than extrapolate
RMP DATA FOSTER COLLABORATIONS & INNOVATIONS MEANINGFUL WATER QUALITY CRITERIA
EMERGING CONCERNS Population growth water demands contaminant inputs Urbanization surface runoff Negative sediment budget contaminant re-exposure Global warming reduced fresh water flows reduced sediment flows Sewall and Sloan, 2004, JGR
