During most of the summer 2001 HyCODE field campaign a region of clear-over-turbid water existed near the 50 m isobath. Clear water (a(488)=0.05 m-1) was observed to exist in the top 10 m of the water column. At 10 m the magnitude of the inherent optical properties increased rapidly (a(488)=0.12 m-1) and continued to increase with depth to 20 m (a(488)=0.24 m-1) below which is decreased. Using the measured inherent optical properties we apply radiative transfer modeling to examine the difference between reflectance from a case with a homogeneous clear layer and a case with the subsurface structure present. By displacing the clear-turbid interface we examine how an internal wave field would modulate the remotely sensed reflectance. Measured remotely sensed reflectances are then used to determine if internal waves were observed.Pegau, W.S. and E. Boss, 2002.
