“…Other systems use a stimulating grid mounted on oceanographic instruments, such as CTD, to obtain vertical pelagic profiling of bioluminescence via photomultiplying cameras (e.g., the Image Intensified Silicon Intensifier Target-ISIT; the Image Intensified Charge Coupled Device for Deep-sea Research, ICDeep; e.g., Craig et al, 2015). Alternatively, other imaging systems have been developed, that is, the extreme low-light working LuSEApher camera with photon counting capability (e.g., Barbier et al, 2012;Dominjon et al, 2012) Other means for measuring the bioluminescence of organisms are provided by deep-sea neutrino telescopes (Martini et al, 2016;Aguzzi et al, 2017). Their mooringlike towers cover the benthopelagic dimension and are primarily instrumented with thousands of photon-detecting sensors (i.e., photomultiplier tubes, PMTs) (FIG.…”
