NURP Project: Understanding how biofouling microorganisms navigate the air-water interface (WP# 20-000000793)

Abstract

In this proposed basic research effort, we will perform laboratory experiments and complementary modeling to understand the effect of interfaces on transport and settling processes in biofouling. Based upon previous laboratory and field work we conducted as part of the Office of Naval Research (ONR) Navy Undersea Research Program as well as ONR s Biofouling program, we believe that the air-sea interface and gas-liquid interface in bubbles play a role in the motion and settling of biofouling microorganisms. Yet, the fundamental mechanisms at such interfaces have not been extensively studied in this context. In this research, we will design controlled, representative laboratory experiments and use live microorganisms and model particles to establish the basic physics, develop scaling relations and derive simple models of the behavior of biological particles/larva at interfaces. Barnacles are a canonical biofouling organism, and we have begun working with barnacle cyprids (larva), which will be used as model microorganisms in this research. The graduate student that will be supported by this award will carry out the work both at Boston University (BU) and at the Naval Undersea Warfare Center (NUWC) Division Newport,taking advantage of expertise and facilities at both organizations.
