The TSRB is an optical instrument designed to make continuous measurements of downwelling irradiance just above the sea surface, upwelling radiance just below the sea surface, and sea surface temperature at the sea surface.
The instrument used measures downwelling irradiance at 489nm and upwelling radiance at 410, 444, 489, 511, 553, 668 and 684nm.
All wavelengths except the 684nm waveband have bandpasses of approximately 20nm. The 684nm waveband has a bandpass of 10nm. The sampling frequency is 1 Hz.
This study is a collaborative effort between the College of Oceanic and Atmospheric Sciences of Oregon State University and the Laboratory for Microbial Oceanography of the University of Hawai'i at Manoa.
