In most cases, bioluminescent organisms produce light in response to mechanical stimulation, including from shear around objects moving in the water. Many phytoplankton and zooplankton are capable of producing bioluminescence, which is commonly measured as bioluminescence potential, defined as mechanically stimulated light measured inside of a chambered pump-through bathyphotometer. We have developed a numerical model of a pump-through bathyphotometer and simulated flow using Lagrangian particles as an approximation for bioluminescent marine plankton taxa. The results indicate that all particles remain in the detection chamber for a residence time of at least 0.25 s. This suggests that the total first flash of bioluminescent autotrophic and heterotrophic dinoflagellates will be measured based on the existing literature regarding their flash duration. We have found low sensitivity of particle residence time to variations in particle size, density, or measurement depth. In addition, the results show that a high percentage of organisms may experience stimulation well before the detection chamber, or even multiple stimulations within the detection chamber. The results of this work serve to inform the processing of current bioluminescent potential data and assist in the development of future instruments.<\/jats:p>","DOI":"10.3390\/s24061958","type":"journal-article","created":{"date-parts":[[2024,3,20]],"date-time":"2024-03-20T05:04:12Z","timestamp":1710911052000},"page":"1958","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Marine Bioluminescence: Simulation of Dynamics within a Pump-Through Bathyphotometer"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-8221-8410","authenticated-orcid":false,"given":"Austin","family":"Thombs","sequence":"first","affiliation":[{"name":"Naval Research Laboratory, Stennis Space Center, MS 39529, USA"},{"name":"Department of Aerospace Engineering, Texas A&M University, College Station, TX 77840, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Igor","family":"Shulman","sequence":"additional","affiliation":[{"name":"Naval Research Laboratory, Stennis Space Center, MS 39529, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0433-8397","authenticated-orcid":false,"given":"Silvia","family":"Matt","sequence":"additional","affiliation":[{"name":"Naval Research Laboratory, Stennis Space Center, MS 39529, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"443","DOI":"10.1146\/annurev-marine-120308-081028","article-title":"Bioluminescence in the sea","volume":"2","author":"Haddock","year":"2010","journal-title":"Annu.
