Director's Statement
In the report "Confronting Climate Change in California," the Union of Concerned Scientists and the Ecological Society of America note that the "past century has seen an apparent four-fold increase in the rate at which the earth is warming." With the dramatic effects of climate events such as El Niņo and current trends in global greenhouse-gas and aerosol emissions, the considerable impact on our environment and economy is increasingly in the spotlight. State and federal policy makers are looking to the scientific community to provide the data necessary to help them in making policy decisions relating to the environment. ICESS, with an infrastructure that promotes long-term multi-process environmental research that addresses the ways the physical, chemical, and biogeochemical systems function, is uniquely positioned to provide this input.
While virtually all ICESS
principal investigators are involved in one or more long-term research
projects, some of our newer researchers have brought to ICESS exciting projects
ranging from transformations of pollutants to climate modeling. Dr. Charles
Jones, for instance, is studying the dynamics of the Madden-Julian Oscillation,
an oscillation of the atmosphere-ocean system in the tropical regions that
seems to be linked to many short-term climate changes. His studies show that
the frequency of extreme events is higher when tropical activity associated
with the MJO is high, as opposed to periods of quiescent phases of the
oscillation. Additionally, a slight preference for a higher number of events is
observed when convective anomalies are located in the Indian Ocean. Dr. Natalie Mahowald, along with several
other ICESS investigators, has begun a project involving the numerical modeling
of dust transport in the Africa and Atlantic regions and their impact on
climate variability. While these two
projects focus strongly on computing and climate modeling, Dr. Patricia
Holden's research efforts have been focusing on the seasonal effects on soil
bacterial processing and the presence and origins of pathogenic microbes in
coastal waters. Thus far, her group has
generated two organisms that fluoresce when they produce pollutant-solubilizing
compounds. They envision using these
organisms for improving the basic understanding of soil microbial function and,
perhaps, as real-time bio-sensors for pollutants.
Within ICESS,
interdisciplinary scientific research is actively promoted through shared
resources, scientific collaboration, and graduate student education. Faculty,
researchers, and students from a variety of disciplines address environmental
issues, studying the Earth as a complex system. For instance, we recently
completed significant upgrades to the computing infrastructure including a file
management system scaleable to 6.7TB, a tape library/back-up system, network
switches capable of 100Mbps, a computational task scheduler, two Compaq/Digital
Alpha XP1000 compute servers (each with 1.5GB of RAM). An SGI Origin 2000 was
acquired to allow large computations as required for simulation of regional and
climate modeling. These upgrades assist ICESS in furthering collaborative
research within the unit.
As an Organized Research
Unit, our mission continues to be "to provide a distributed,
interdisciplinary computer environment for the promotion and support of
research and research education in Earth system science, an interdisciplinary
environment and computer-related service that enhances the excellence and
competitive advantage of UCSB global change research, a center of excellence to
provide visibility and aid in the attraction of top faculty and students to
UCSB, and an efficiently-run business operations and administration that
supports research".
In
conclusion, the past year has brought some interesting changes to the research
groups within ICESS. Through mentoring
by established faculty and researchers, the research programs of younger
faculty and researchers have begun to flourish. Fostering the development of these ten young research groups has
proven very exciting. We have high
hopes for each of these newer teams and look forward to their continuing
contributions to the interdisciplinary research that takes place within ICESS.
