A synthesis study of the terrestrial ecosystem carbon cycle at various temporal and spatial scales

This research includes analyzing the impacts of wildfires on the global terrestrial biosphere carbon cycle, assessing the patterns of biome carbon fluxes in response to droughts at different time scales, and estimating carbon fluxes with Terrestrial Ecosystem Model. This includes modeling the lateral dissolved organic carbon (DOC) flux into an earth system model. The lateral […]

Wouter Hantson

Wouter Hantson is a PhD candidate in the School of Forest Resources.  His research focuses on investigating the patterns of vegetation-permafrost dynamics as determined by landscape-scale disturbance.  His research activities are organized within three objectives designed to build a scaling framework to: Measure the local-scale heterogeneity of vegetation composition and structure along gradients of disturbance […]

An Assessment of Aerial Survey Acquisition Methods for Generating Forest Inventory Models

Structure from motion (SfM) derived three dimensional (3D) point clouds have performed well in comparison to airborne laser scanning (ALS) in generating timber inventory models, yet little has been done to assess the viability of a wide range of aerial image acquisition methods for developing these models. Remote sensing factors such as sensor reflectance characteristics, […]

Measurements, Models and Maps: Large-area Forest Inventory from Airborne LiDAR Data

This project has organized and carried out initial investigations into the use of LiDAR remote sensing analysis to enhance the design and operation of inventory programs for Maine’s forest industry stakeholders. The research conducted here is evaluating ground-based inventory plot designs together with existing, publicly-available Airborne Laser Scanning (ALS) data sets processed in a high […]

Valeria Briones

Valeria Briones is an MS candidate in the School of Forest Resources.  Climate warming is affecting the social and ecological systems of the northeastern U.S., including changes in the seasonal timing and duration of biophysical processes.  Phenology is the repeated occurrence of seasonal cycles, which are influenced by climate, thus it is important to understand […]

Catherine Chan

Catherine Chan is an MS candidate in the School of Forest Resources.  Her research is focused on the advanced detection of health stress in agricultural fields and forests, which can prompt management responses to mitigate detrimental conditions such as nutrient deficiencies and disease.  New applications in hyperspectral data and imaging spectroscopy to agriculture and forests […]
