“…[ 34 ] In waters off the south coast of Sri Lanka a thin BP maximum was traced in the upper mixed layer (at ~40–60 m depth) while the deep chlorophyll maximum was located at ~70–90 m depth during the winter monsoon. [ 16 ] Here, 22 bioluminescent zooplankton species were identified during this study.…”

“…Several older publications featured bathyphotometric measurements carried out in the 1980s, [14,15] although some casts were deployed in coastal waters of Sri Lanka in 2016. [16] In addressing the issue of multiple-scale variability, first we aimed to understand the bioluminescence on a mesoscale that contributes gradually to spatiotemporal variations of structural characteristics of the Indian Ocean plankton communities. Mesoscale eddies act as a dynamic force modulating these variations.…”

Large‐scale surveys represented by 5800 bathymetric casts in the western Indian Ocean (0–22oN, 54–58oE), elucidated the 10‐fold variation of the bioluminescent potential (BP) in the upper mixed layer, during the winter (north‐east) monsoon season. The mesoscale survey in February 2017 consisted of 26 drift stations (4oN–3oS, 65–68oE) on which 5–10 bathymetric casts were deployed down to 60 m. The maximal BP was associated with the periphery of a cyclonic eddy. The two‐fold to three‐fold variation of BP characterized the spatial heterogeneity modulated by a detected eddy. High‐frequency casts on drift stations resembled the fine‐scale heterogeneity in which the three‐fold variation was observed within the BP maximum at a 37 ± 13 m depth. The latter one was located above the deep chlorophyll maximum at a 80 m depth. A general decline of the BP variance from the large scale through mesoscale to fine scale, fits that of the zooplankton biomass.

“…Lapota et al (1989) estimated the bioluminescence of zooplankton in the first 100 m of Vestfjord, Norway was approximately 4% of the total bioluminescence measured, although bioluminescent zooplankton biomass was also low during the sampling period. With these differences in mind, it is clear that a multitude of variables can affect the bioluminescence of a given system, e.g., timing, location, primary production, diversity, and community composition (Neilson et al, 1995;Craig et al, 2010;Haddock et al, 2010;Wimalasiri et al, 2020). For example, recent increases in temperature in Antarctic waters have changed the planktonic community from dominant krill swarms to salp colonies, reducing the bioluminescence of the water column by half (Melnik et al, 2021).…”

“…When measuring bioluminescence throughout the water column, peak MSL usually occurs in the mixed layer or near the thermocline (Wimalasiri et al, 2020). Indeed, this is typically a region of higher phytoplankton productivity, on which bioluminescent zooplankton can thrive.…”

Bioluminescence is ubiquitous in marine ecosystems and found in uni- and multicellular organisms. Bioluminescent displays can be used to deter predators, attract mates, and lure and hunt prey. Mechanically stimulated flash kinetics of zooplankton and dinoflagellates are life stage-dependent and species-specific, and could prove effective at identification and monitoring biodiversity in bioluminescent species. Here, we provide a comprehensive review of mechanically stimulated bioluminescence for the main dinoflagellate and zooplankton clades in marine environments and assemble known flash kinetics and spectral emission data. Instruments and methods used in measuring bioluminescence are also discussed. Applications, research gaps, perspectives, and biases in approaches to studying bioluminescence are identified. Moreover, emission kinetics of most zooplankton are very poorly known and constitute a critical gap. Lastly, available knowledge is interpreted in terms of potential future changes in global bioluminescence driven by climate change.
