SYNERGISTIC ACTIVITIES:
(1) Extramural funding: NOAA,NASA,NSF, U.S. EPA,U.S. DOE,U.S-IsraelBi-national Science Foundation,
National Environment Research Council (U.K.); total awarded to Schalles Lab at Creighton University ~ $1.45
million. 3. Georgia Coastal Ecosystems LTER: Research Associate (2006-2012); Project Investigator (2012-
2018). In the GCE project, I perform geospatial analysis of salt marsh community composition, above-ground

2. biomass assessments,marsh / tidal creek exchanges,and open water phytoplankton chlorophyll patterns. In the
current GCE3 project (2012 - 2018), I help coordinate geospatial activities, including: use of historic imagery
(esp. LANDSAT TM) to assess inter-annual variability and spatial patterns in above-ground salt marsh biomass;
acquisitions of high-spatial resolution imagery to map community composition and structure across the larger
GCE domain of the central Georgia coast; and examine relationships between the new GCE flux tower data with
spatial-temporal dynamics of the surrounding salt marsh community. Also, my students and I participate in the
LTER Schoolyard project for K-12 teachers during summer residency at the Univ. of Georgia Marine Institute.

term monitoring. I served as Lead Scientist for the ECSC Geospatial Analysis thematic area the past 8 years; my
work included planning, supervision of field surveys, and coordination of data analysis and mapping products for
nine hyperspectral AISA airborne imaging missions at seven NOAA-NERR sites on the Gulf and East Coasts. In
the current ECSC funding, I lead a project using WorldView 2 high spatial resolution imagery to assess salt marsh
community structure and biomass patterns with multi-date imagery at four Gulf Coast NERR and NMS sites.
