A Comparison of Remote Sensing Methods for Estimating Above-Ground Carbon Biomass at a Wetland Restoration Area in the Southeastern Coastal Plain
(2012-04-19)Developing accurate but inexpensive methods for estimating above-ground carbon biomass is an important technical challenge that must be overcome before a carbon offset market can be successfully implemented. Previous studies ... -
A Qualitative Characterization of Spring Vegetation Phenology Using MODIS Imagery for the Piedmont of North Carolina from 2000 to 2007
(2008-08-29)Recent studies have shown vegetation phenology around the world is being altered by increased variability in temperatures associated with a warming climate. The onset of spring and the duration of the growing season in ... -
An Analysis Comparing Mangrove Conditions under Different Management Scenarios in Southeast Asia
(2017-04-27)Mangroves in Phang Nga Bay, Thailand and in Matang Mangrove Reserve, Malaysia serve a variety of crucial ecosystem services. However, they are threatened by various natural and human-influenced factors such as tsunami damage ... -
ASSESSMENT OF THE IMPACT OF SHRIMP AQUACULTURE IN NORTHEAST BRAZIL: A REMOTE SENSING APPROACH TO COASTAL HABITAT CHANGE DETECTION
(2007-05)Aquaculture is the fastest growing sector of food production in the world. However, rapid expansion of shrimp aquaculture ponds may induce potentially detrimental changes in extent and health of coastal habitats utilized ... -
Exploiting Multi-Look Information for Landmine Detection in Forward Looking Infrared Video
(2013)Forward Looking Infrared (FLIR) cameras have recently been studied as a sensing modality for use in landmine detection systems. FLIR-based detection systems benefit from larger standoff distances and faster rates of advance ... -
Identification of Green Space Attributes that Optimally Reduce the Urban Heat Island Effect in Los Angeles
(2022-04-20)The urban heat island (UHI) effect is one of the many challenges facing urban development as climate change and urbanization increase. The UHI effect refers to a phenomenon in which dense concentrations of impermeable building ... -
Improving Global Restoration Monitoring
(2023-04-28)Forests are important carbon pools that are facing many man-made threats such as poverty, agricultural expansion, mismanagement, illegal logging, and many other factors. Conservation International (CI) has been working on ... -
Micro-topographic roughness analysis (MTRA) highlights minimally eroded terrain in a landscape severely impacted by historic agriculture
(Remote Sensing of Environment, 2019-03-01)© 2018 Elsevier Inc. The 190 km2 Calhoun Critical Zone Observatory in the Piedmont region of South Carolina, USA lies in an ancient, highly weathered landscape transformed by historic agricultural erosion. Following the ... -
Remote Sensing Tree Physiology
(2021-08-17)Transpiration, or plant water loss, is a critical component of water balance and flux for terrestrial systems worldwide, yet uncertainty in large-scale estimates create significant challenges for water resource forecasting ... -
Remotely Sensed Estimates and Controls of Large-Scale Oceanic Net Community Production
(2017)Oceanic net community production (NCP), defined as photosynthesis in excess of respiration, lowers the CO2 concentration at the ocean surface and in the process regulates atmospheric CO2 levels on seasonal to glacial-interglacial ... -
Understanding the Coupled Surface-Groundwater System from Event to Decadal Scale using an Un-calibrated Hydrologic Model and Data Assimilation
(2015)In this dissertation, a Hydrologic Data Assimilation System (HDAS) relying on the Duke Coupled surface-groundwater Hydrology Model (DCHM) and various data assimilation techniques including EnKF (Ensemble Kalman Filter), ... -
Visualizing Vulci: Reimagining an Etruscan-Roman City
(2021)The Etruscan-Roman city of Vulci is one of many Etruscan cities which lacks a detailed and holistic understanding of its urban development. Vulci represents a rare site that was not covered by modern structures and thus ...
