Modeling Deep-Sea Bioluminescence — •Stephan Meighen-Berger¹ and Li Ruohan² — ¹Technische Universität München, James-Franck-Straße, 85748, Garching — ²Ludwig-Maximilians-Universität München, Schellingstraße 4, 80799, München

We present a new modeling framework for simulating deep-sea organisms and their luminescence which is detectable by neutrino detectors, such as KM3Net, Antares, and P-ONE. This bioluminescence light is a unique background for deep-sea instruments, due to the emission spectra covering the expected Cherenkov peak. The emission itself is predominantly caused by the organisms' defensive response to turbulences caused by detectors' super-structures. Designed for a broad range of Reynold's numbers, the framework employs Monte Carlo methods to model individual organisms. It provides methods to solve the underlying Navier-Stokes equation, using Streamline Upwind Petrov Galerkin Method in the velocity equation to avoid instabilities. In this talk, we present the framework, lessons learned from this new exact modeling scheme, and unique signatures that can be used to identify the organisms, bridging the gap between physics and biology.
