Reflectance and Fluorescence Index
Welcome to the spectral reflectance and fluorescence index! Presented here is data that was collected during an MIT Sea Grant project. The goal of the project was to make spectral reflectance a reliable method of identifying Didemnum sp..
Each link will direct you to a space delimited .ascii file containing wavelength numbers in the first row and percent reflectance or fluorescence data in the following rows. Reflectance Data has been divided into three main categories: Ambient, Illuminated, and DiveSpec. "Ambient" and "Illuminated" are in situ reflectance measurements using a Satlantic HyperOCR radiometer. "DiveSpec" files contain reflectance measurements that were taken using the DiveSpec, a self contained submersible radiometer and fluorometer. DiveSpec data was collected both in the lab and in situ.
All reflectance data has been referenced to a 99% reflectance standard and therefore all reflectance data is in percent reflectance. Fluorescence data is in absolute units and the spike seen from about 400-500nm is blue light produced by the DiveSpec. Ambient and Illuminated files contain multiple reflectance spectra, DiveSpec data contains one.
