Abstract: In-water algorithms for OCTS standard products were developed using in situ data and installed for operationally processing at NASDA/EOC. This paper describes the in-water algorithms Version 1.0 for chlorophyll aconcentration, pigment concentration, and attenuation coefficient at a wavelength of 490 nm. The selected OCTS standard algorithms (Ver. 1.0) are as follows:

Chl = 0.2818((L4+L5)/L3)3.497
Pig = 1.568(L2/L4)-2.079(L3/L4)-3.498
K490 = 0.0391((L4+L5)/L2)1.691
