Abstract: During my six months internship at the Kelly Lab -ESPM -Department of Environmental Science, Policy and Management at UC Berkeley, I had the opportunity to work on a state-founded three-years research project called ‘Carbon Capture Wetland Farming (CCWF)’ lead by the U.S. Geological Survey and in collaboration with UC Berkeley. The project tests a range of experimental, optimal and natural environment condition in a farm-scale experimental wetland on Twitchell Island in the western Delta, California, with the goal of optimizing land accretion and net sequestration of greenhouse gas, combining field and remote sensing techniques for estimating above and belowground productivity of wetland vegetation. I focused on the processing of high resolution (1.8 meter), 8-band WorldView2 Digital Globe satellite data and creation of land cover maps using ENVI-ITT and IDRISI-Taiga Hard and Soft Classifiers algorithms in order to better understand the complex compositions of the experimental area. We also used linear regression models to find a relationship able to predict plant biomass in all the wetland area. For this purpose we evaluate the correlation coefficient between sampled Biomass data and new vegetation indices obtained testing several WV2 band combinations.
