Description:

Range-resolved detection of submerged scattering layers was investigated in the Gulf of Mexico based on vertical profiles made with a LiDAR (Light detection and range) system having a green laser (wavelength λ = 532 nm). The backscattering power (Sd) variability was decomposed in principal components (PCs) and related to non-polarized Sd, the Sd ratio between cross- and co-polarized waveforms, the chlorophyll-a fluorescence (Fchl), and the ratio between volume scattering angles of 150° and 100°. The variance of PCs was dominated by non-polarized Sd followed by Fchl. Correlation between PC1 scores and Fchl anomalies suggested that Sd was mainly originated from pigmented particulates.
