Pedro Oliveira awarded a 2018 NASA Earth & Space Sciences Fellowship

Pedro Oliveira was awarded a 2018 NASA Earth & Space Sciences Fellowship for his proposal entitled Integrating Airborne LiDAR, Landsat-8 and Sentinel-2 Data to Map Brazilian Amazon Tropical Moist Forest Biome (BATMFB) Canopy Height. His advisor is Prof. David Roy. The goal of his three year PhD research funding proposal is to use Landsat-8, Sentinel-2 and Brazilian Space Agency (INPE) airborne LiDAR data to investigate canopy height estimation. Canopy height is a predictor of above ground biomass and repeat maps provide information on carbon stocks and fluxes. The proposed research is responsive to the NASA focus on carbon cycle and ecosystems and is responsive to the upcoming NASA GEDI satellite LiDAR mission. NASA received a total of 424 applications of which 54 were selected. A full list of awarded grants is at

Megan Garms successfully completes the 2017-2018 GSCE Center Scholars Program

Megan Garms signed up for the Center Scholars Program, a research experience for undergraduates that teams motivated juniors with GSCE scientists. She has been working with Dr. Izaya Numata (at right in picture) and, earlier, Dr. Mark Cochrane to use geospatial technologies to analyze the regrowth and development of forests in the Amazon Basin in areas where logging had occurred. Megan has worked up to 10 hours per week during the school year (SP17, FA17, SP18) and more hours last summer. An Honors student, Megan is graduating in May from SDSU with a BS in Wildlife and Fisheries Sciences and a minor in Animal Health. She will be pursuing a DVM at Iowa State University in the fall. Congratulations to Megan!

Megan presented her research project entitled "Assessing Dynamics of Secondary Forest in Southwestern Amazonia Using Landsat Time Series Data" at the Undergraduate Research, Scholarship, and Creative Activity Day (URSCAD) on April 3rd. Her poster abstract follows:

The goal of this project was to monitor and study the dynamics of secondary forests in the Amazon over 31 years using available satellite data. The activities involve 1) development of annual land cover maps using a decision tree classification technique; 2) assess the accuracy of land cover map products using high spatial resolution data; and 3) identify spatial and temporal changes of secondary forest areas, its ages throughout a 1985 – 2016 study period. Based upon the results from 3), potential implications of secondary forest dynamics for carbon cycle in the Amazon will be discussed.
