Project 2: Hyperspectral Measurements to Monitor Pigments and Nutrients Composition in Temperate Tidal Salt marshes
Phenology changes in tidal saltmarshes are related with changes in vegetation pigments and nutrients composition. Near-Surface Remote Sensing (NSRS) techniques, such as hyperspectral measurements, are non-destructive methods to identify and monitor changes of plant physiology and phenology. In this project, we use hyperspectral measurements between 350 nm to 900 nm (1 nm of spectral resolution) and 700 nm to 820 nm (0.1 nm of spectral resolution) to derive vegetation indexes and to identify and monitor changes in chlorophyll, carotenoids, nitrogen and silica in tidal saltmarshes of St. Jones Reserve, Del.
The main activities for this project are: a) to extract vegetation pigments in the lab (from previous collections) and b) to prepare, process and analyze hyperspectral measurements collected from September 2016 to December 2017. All data processes and analyses are done in R package. We are waiting as potential results to identify vegetation indexes that can help to explain changes in phenology/physiology of tidal saltmarshes of Delaware.
Time requirement for this project:
- 4 hours per day during the summer (early July to early October)
Location: Newark campus and field trips to the St. Jones Reserve near Dover, Del.
