The image below shows how photography of the sea surface can be used to map surface features. The photo in the upper right hand corner was taken from the control booth on the Casco Bay Bridge in Portland, Maine. The image on the left is the georectification of the same photo, superimposed on an aerial image of the harbor. Using this technique, combined with time-lapse photography, we can study the dynamics of the fluid in the harbor. We can also trace the movement of visible phenomena, such as sea ice or biogenic oil.
We have collected many months of time-lapse photography of the sea surface, mostly in Portland Harbor. Our system typically takes a photo once per minute. We will discuss our results in later entries, and include some cool animations.
