INTENSIVELY LEARNING OPTICAL OCEANOGRAPHY: THE EFFECT OF SUBSURFACE BUBBLES IN THE WAKES OF LARGE SHIPS ON REMOTE SENSING REFLECTANCE
 
On 13 August 1998, approximately one week after aircraft remote sensing overflights, sea-surface reflectance was measured from the RV Nugget, both outside and within the wake of several large vessels in the waters of the San Juan Islands, WA. As expected, the comparison of the computed remote sensing reflectance taken at various times before and after the passage of vessels showed dramatically elevated reflectance immediately following the vessels passage. However, the contribution of the lingering small bubbles present in a ship's wake not only increased the reflectance, but also included a spectral component. Consideration of ship wakes may be needed during the analysis of hyperspectral airborne remote sensing packages with spatial resolutions in the tens of meters. Such sensors were used during the ocean optics course held at the University of Washington's Friday Harbor Laboratories in the summer of 1998.
