“…Most eukaryotic organisms emit a single light flash or a series of flashes; a rapid increase of the luminosity indicates the start of a flash which—after reaching its peak value—is decaying exponentially with a time constant significantly longer than that of the initial rise. Studies have characterized such flash light curves from various species by the duration, the maximum photon flux, and the total photon emission of the flash (Esaias et al 1973; Galt and Sykes 1983; Morin 1983; Lapota and Losee 1984; Galt et al 1985; Herring 1988; Batchelder and Swift 1989; Lapota et al 1989; Buskey and Swift 1990; Batchelder et al 1992; Buskey 1992; Herring et al 1993; Swift et al 1995; Latz and Jeong 1996; Latz et al 2004; Widder 2010; Lapota 2012; Valiadi and Iglesias‐Rodriguez 2013; Johnsen et al 2014; Craig et al 2015; Cronin et al 2016; Messié et al 2019).

We develop a novel technique to exploit the extensive data sets provided by underwater neutrino telescopes to gain information on bioluminescence in the deep sea. The passive nature of the telescopes gives us the unique opportunity to infer information on bioluminescent organisms without actively interfering with them. We propose a statistical method that allows us to reconstruct the light emission of individual organisms, as well as their location and movement. A mathematical model is built to describe the measurement process of underwater neutrino telescopes and the signal generation of the biological organisms. The Metric Gaussian Variational Inference algorithm is used to reconstruct the model parameters using photon counts recorded by photomultiplier tubes. We apply this method to synthetic data sets and data collected by the ANTARES neutrino telescope. The telescope is located 40 km off the French coast and fixed to the sea floor at a depth of 2475 m. The runs with synthetic data reveal that we can model the emitted bioluminescent flashes of the organisms. Furthermore, we find that the spatial resolution of the localization of light sources highly depends on the configuration of the telescope. Precise measurements of the efficiencies of the detectors and the attenuation length of the water are crucial to reconstruct the light emission. Finally, the application to ANTARES data reveals the first localizations of bioluminescent organisms using neutrino telescope data.
