Quantification and Mapping Sawgrass Marsh Aboveground
Biomass in the Coastal Everglades.
This project investigated sawgrass biomass estimation using Landsat
data and developed an object-based ensemble approach for better
biomass mapping in the coastal Everglades.
Examining the Effects of Salinity, Nutrients,
and Sea Level Rise on Vegetation Using Remote Sensing Spectroscopy
This project examines the effects of salinity, nutrients,
and sea level rise on plant stress using spectroscopy techniques by collecting
data under controlled environments. The project was completed at FAU Greenhouse
and hyperspectral laboratory by Dr. Donna Selch, a former Ph.D. student
of Dr. Zhang.
Mapping Benthic Habits in the Florida Keys
Using Hyperspectral Remote Sensing Techniques.
This project explores the potential of the application of fine
spatial resolution hyperspectral imagery alone, and fusion of 20-m hyperspectral
imagery and 1-foot aerial photography for benthic habitat mapping in
the Florida Keys.
Research and Technical
Assistance for Assessing: Climate Change, Sea Level Rise and Salinity
Dynamics in the Greater Everglades. PI: Dr. Leonard Berry, Co-PIs: Drs. Caiyun Zhang, Charles
Roberts, and Zhixiao Xie. U.S. Geological Survey (USGS).
South Florida is one of the world’s most vulnerable areas to
climate change, especially sea level rise. The potential adaptation
to sea level rise is complicated by the porous limestone geology of
the region, permitting salt water intrusion into important aquifers
and by the low level terrain in many areas which make even a
relatively small sea level rise problematic. Already past sea level
rise is impacting canal outfalls in Dade County. Scientist, city and
county officials and agencies that work in the affected area are well
aware of the pressing nature of these issues. The activities of this
project include: 1) synthesis, workshops and working groups on
climate change, sea level rise and salinity dynamics, and 2) changing
salinity as an indicator of restoration and climate change impacts on
the Greater Everglades.
Salinity Assessment in
Northeastern Florida Bay Using Landsat TM Data. PI: Caiyun Zhang,
with Dr. Zhixiao Xie as mentor. FAU Faculty Research Mentoring
This project examines the potential of Landsat
Thematic Mapper (TM) for salinity assessment in the Greater Everglades
of South Florida with the Northeastern Florida Bay as study site.
Water Quality Assessment in
Florida Bay Using Remote Sensing Techniques. PI: Caiyun Zhang,
Co-PIs: Drs. Tara L. Root, Zhixiao Xie, Marguerite Koch-Rose,
and Leonard Berry. FAU
2012 Seed Program.
The objective of this project is to examine the
potential of several remote sensors for assessing water quality in
Florida Bay, and test the sensitivity of spectral signatures measured
by a spectroradiometer for water samples collected from regions with
different nutrient concentrations and/or different seagrass species
Mapping Urban Composites Using Medium Resolution
This project developed object-based mixture
analysis techniques for mapping and quantifying urban composites
(impervious surface and vegetation) using multispectral Landsat imagery
and hyperspectral EO-1/Hyperion imagery.
