NSF-CBMS Regional Conference on Environmental Statistics 148 1. Summary In 1996 the US EPA awarded a five-year cooperative agreement with the
University of Washington to create a national center for environmental
statistical research. On September 10, 2001, the National Research Center
for Statistics and the Environment was notified that its funding would not
be renewed. A one-year no-cost extension was allowed, and on September 30,
2002, the EPA funding of the Center ended. This report describes the
scientific results of the $5,380,207 awarded to the University. The Center
has organized or co-organized 14 workshops and two conferences. The 33
Center members, 3 postdoctoral researchers, and 29 graduate students have
made 164 presentations at national and international scientific meetings,
published 6 books, and 138 scientific papers. In all, 229 visitors spent
time at NRCSE or NRCSE-organized events at the University of Washington
campus. 44 different research projects were pursued at the Center, and 7
outside subcontracts were awarded. 11 doctoral degrees and 9 Master's
degrees have been earned by NRCSE-funded graduate students. 2. Outreach activities
2.1 Seminars The first activite of the newly formed Center was to organize a seminar
series with speakers including local consultants, EPA Region X and
Washington Department of Ecology staff, Center members and visiting
faculty. The seminar series was organized as an official University course,
and had about half a dozen registered students. An informal summer seminar
series featured mainly Center visitors. Attendance during the first year
varied from 20 to 60, with an average attendance of about 40 in Autumn
quarter, 35 in Winter quarter, and 30 in Spring quarter .The second year
most seminars had 20-30 attending. During the second year, we added the service of maintaining streaming video
and speaker slides on the web The service requires a special plugin which
is available for free download at the web site. The most popular seminars
were those of Chris Glasbey, Statistics Scotland, on image warping (40
requests outside the washington.edu domain) and of Joel Reynolds, NRCSE, on
Pareto optimal model assessment (32 requests). While it is not generally
possible to resolve where each visit originates, out of resolvable
addresses 1/3 came from .edu (mainly US educational institutions), slightly
fewer from the commercial .com and .net domains, while about a quarter came
from European Union sites and 8% from .gov (US government sites). In 1997-98, a committee was formed to study the seminar organization and
structure. The main recommendations were
to have faculty members organize the seminars with about half the seminars
each quarter falling into a coherent theme
to develop a Center newsletter
to use seminars as a focal point for Center communication and interaction The seminar series during the academic year 1998-99 had a quarterly theme.
In Autumn 98 the theme was particulate matter air pollution, while in
Winter the theme was assessment of environmental and ecological models. The
Spring quarter seminar series focused on student and post-doctoral
researchers presenting their current work, and was carried out jointly with
the graduate program on Quantitative Ecology and Resource Management.
During Autumn and Winter all seminars were videotaped and made available on
the web. Since the University has several weekly statistical seminar series, there
had been relatively sparse attendance at NRCSE seminar. A decision was made
to limit the NRCSE seminars to three per quarter, and make them joint with
other groups.. In addition to the seminars, the Center organized afternoon
workshops to cover in more depth areas of interest to Center members. These
workshops started in Winter quarter 2000. A list of all seminars is in
Appendix A. 2.2 Web site The Center site at the World-Wide Web (http://www.nrcse.washington.edu/) is
a key part of its informational outreach. Much care went into designing
the web site to have a consistent look between pages, and be easy to
