Project Number | 594 |
Date of Summary | June 5, 2008 |
Subject | Development of a Portable Multispectral Aerial Sensor for Real-time Oil Spill Thickness Mapping in Coastal and Offshore Waters |
Performing Activity | Ocean Imaging Corporation |
Principal Investigator | Mr. Judd Muskat |
Contracting Agency | Minerals Management Service |
Estimated Completion | September 30, 2008 |
Description |
This research project will develop a portable, easy-to-operate, aerial
sensor to detect and accurately map the thickness and distribution of an oil
slick in coastal and offshore waters in real-time. Building on previous
research the technical plan, consisting of five phases will lead to the
deployment of an operational system estimated to be completed with 18
months. The five phases are:
This project will include five separate over-flights over the Santa Barbara Channel oil seeps and the Ohmsett facility for sensor and algorithm verification and ground-truthing. This project is co funded with the California Department of Fish and Game, Oil Spill Prevention and Response. |
Progress |
The infra-red camera (IR) and GIS compatible software were received in late September 2007. The camera is being integrated into the detection system and initial test flights of the system will be conducted over the Santa Barbara Channel oil seeps in late October 2007. The Oil Thickness Algorithm Refinement work is being undertaken simultaneously with the IR camera integration. Laboratory experiments and aerial flights were conducted. Two significant improvements to the system were achieved. First, a new wavelength (577 nm) was chosen to provide the greatest thickness distinction range of ratios. Second. When the 577nm band is used in conjunction with the 551nm band it provides additional information to the algorithm to adjust the thickness model for different background water reflectance characteristics. The addition of the IR camera will extend the available thickness measurement range. The thickness sensor system with be flight tested in day/night operations at Ohmsett – The National Oil Spill Response Test Facility June 16-20, 2008. |
