Biological Response to the Dynamic Spectral-Polarized Underwater Light Field
Abstract
Camouflage in marine environments requires matching all of the background optical properties: spectral, intensity and polarization components - all of which can change dynamically in space and time. Some of the most sophisticated examples of camouflage occur in our oceans, where precise regulation of spectral and polarized reflectivity is achieved through poorly understood mechanisms. Our research investigates the biological challenge of camouflage in the near-shore littoral zone and near-surface marine environments in two distinct water types found in coastal environments around the globe (oligotrophic and eutrophic). We aim to characterize the dynamic light field along with the behavioral and cellular response of camouflaging animals in these environments. Our long-term goal is to identify the biological pathways for concealment against the underwater spectral-polarized light field enabling us to identify design principles for future naval camouflage. OBJECTIVES (1) Measure and model the underwater spectral-polarized light field in oligotrophic and eutrophic systems (2) Quantify the biological response in fish and cephalopods to these dynamic underwater optical environments (3) Identify the internal controls and structural mechanisms that coordinate the camouflage response in fish and cephalopods.
