Multiple Approaches for Evaluating Novel Marine Coatings in the Pearl Harbor Naval Base and in the Laboratory
Abstract
The Principal Investigators and their associates will provide to ONR-collaborating chemists who are formulating experimental marine coatings the following tests: (1) static field-immersion testing of accumulation of macrofouling organisms in Pearl Harbor, Hawaii, coupled with periodic digital photography, estimates of percent cover, and mechanical force-gauge measurements of adhesion strength of hard-fouling organisms; (2) evaluation of the invertebrate and microbial communities growing on test surfaces in Pearl Harbor; and (3) laboratory evaluation of: (a) the settlement and attachment of tropical fouling animals, especially the tube worm Hydroides elegans, and the ascidian Phallusia philippinensis; (b) fluid shear forces necessary to remove fouling organisms from coated coupons in a calibrated turbulent flow cell; and (c) mechanical forces necessary to remove submerged fouling organisms with a precision motorized force gauge. Overall, we will provide significant and rapid evaluation of experimental coatings in a tropical setting where marine biofouling is rapid and severe. This effort focuses on gaining a much better understanding of the basis of marine biofouling.
