High Resolution Remote Sensing As A Tool To Improve Coastal Habitat Mapping In The Gulf Of Maine, Gabriel Hesketh
High Resolution Remote Sensing As A Tool To Improve Coastal Habitat Mapping In The Gulf Of Maine, Gabriel Hesketh
Electronic Theses and Dissertations
The derivation of oceanographic and biological parameters from remote sensing is well documented across decades of research. Careful evaluation of satellite products provides insight into the optimal algorithms for image processing, research, and various biogeographical applications. Archived multi-satellite data from the United States Geological Survey offers users decades of continuously updated global data, and the agency has recently updated the Landsat portion of its catalog with Collection 2 files, which offers both Level 1 and Level 2 processed data products. Here, we evaluate the Collection 2 improvements using several published algorithms currently used to derive sea surface temperature, chlorophyll, and …
Participatory Modeling Of Tidal Circulation On Maine Mudflats To Improve Water Quality Management Of Shellfish Areas, Gabrielle V. Hillyer
Participatory Modeling Of Tidal Circulation On Maine Mudflats To Improve Water Quality Management Of Shellfish Areas, Gabrielle V. Hillyer
Electronic Theses and Dissertations
Over the past decade, researchers have become increasingly aware of the vital role stakeholder knowledge plays in understanding complex social and environmental problems. Incorporating stakeholder knowledge into understanding complex problems allows for greater awareness and identification of community needs and can help build partnerships to support the development of applied research. In this thesis, I demonstrate the value of stakeholder knowledge and research partnerships by focusing on the soft-shell clamming industry in Maine and how a complex collaboration between clammers, municipal officials, representatives from state agencies, researchers, and other partners relied on and build adaptive capacity to address complex water …
Crowdsourcing Water Quality Data Using The Iphone Camera, Thomas Leeuw
Crowdsourcing Water Quality Data Using The Iphone Camera, Thomas Leeuw
Electronic Theses and Dissertations
The ubiquity and advanced computing power of smartphones make them a potential tool for environmental monitoring on a global scale. In an attempt to tap this resource, a water quality application (HydroColor) was developed. Hydro- Color uses the iPhone’s digital color camera as a primitive three-band radiometer. Using three images taken by the user, HydroColor calculates the remote sensing reflectance in the red, green, and blue color channels of the camera. The absolute or relative reflectance between channels can be used to obtain estimates of chlorophyll, turbidity, suspended particle material, and the backscattering coefficient. In the future, HydroColor will be …
