The remotely sensed signal R(0,z) is a function
of bottom composition (A), water column
composition (R8, K) and water depth
(z). Generally, all are unknowns.

Implicit Water Column Correction Classify the
combined water-leaving radiance signal Requires
spectral library that encompasses
variabilities of both water column and
bottom-type Louchard et al. (2003), Mobley et
al. (2005) propose Euclidean distance
spectrum-matching approach using modeled
spectra This study multivariate classifer
approach using measured spectra

Explicit Water Column Correction Remove water
column effects, then classify Requires inversion
of remotely sensed signal to determine seafloor
spectral reflectance, as well as library of
reflectance spectra Many, many proposed
approaches This study empirical decorrelation
from depth, based on Conger et al. (2006)
