The Salish Sea is a ecologically important coastal region located on the southwest
part of British Columbia. Optical measurements were taken using a set of hyperspectral
radiometers, the SAS Solar Tracker developed by Satlantic. This sensor is
installed on the Queen of Oak Bay ferry, that runs between Nanaimo and Vancouver,
as part of the Ferry Ocean Colour Observation Systems (FOCOS) project. We developed
a computer program to process the raw sensor data and generate remote sensing
reflectance (Rrs) values. This performs similar functions to Prosoft, Satlantic’s own
software to process the data. However, we added new features such as an additional
preprocessing step to filter the data based on longitude, and new meteorological flag
testing and wind speed calculations. The system was tested using Pearson correlation
to compare our output with the output from Satlantic Prosoft. Testing helped
us identify a few issues, such as adding longitude flags to remove data at the start and
end of the trip where the sensor could produce inaccurate results if aiming at land
instead of water. Another issue was where the SAS Solar Tracker does not update
its pointing angle fast enough when the ferry makes sharp turns and could result in
inaccurate data. / Graduate
