Algae in Reef Measurements

Hi Chief Delphi friends,

My team is currently working on a mechanism that involves the algae. We have run into the issue of not knowing the exact location of where the algae falls in the reef. I am looking for measurements like how much wider then poles the algae is and how much it sticks out in the front. Any measurements, height, depth, side to side, are useful.

Thanks in advance.
