We examined its potential during cruises in the Gulf of Mexico and Atlantic Ocean and at a field station on the Great Barrier Reef. First, we collected various species of transparent zooplankton and micronekton and photographed them between crossed polarizers. Many groups, particularly the cephalopods, pelagic snails, salps and ctenophores, were found to have ciliary, muscular or connective tissues with striking birefringence.\n                    <jats:italic>In situ<\/jats:italic>\n                    polarization imagery of the same species showed that, while the degree of underwater polarization was fairly high (approx. 30% in horizontal lines of sight), tissue birefringence played little to no role in increasing visibility. This is most likely due to the low radiance of the horizontal background light when compared with the downwelling irradiance. In fact, the dominant radiance and polarization contrasts are due to unpolarized downwelling light that has been scattered from the animal viewed against the darker and polarized horizontal background light. We show that relatively simple algorithms can use this negative polarization contrast to increase visibility substantially.\n                  <\/jats:p>","DOI":"10.1098\/rstb.2010.0193","type":"journal-article","created":{"date-parts":[[2011,1,31]],"date-time":"2011-01-31T03:38:58Z","timestamp":1296445138000},"page":"655-670","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":63,"title":["Polarization sensitivity as a contrast enhancer in pelagic predators: lessons from\n                    <i>in situ<\/i>\n                    polarization imaging of transparent zooplankton"],"prefix":"10.1098","volume":"366","author":[{"given":"S\u00f6nke","family":"Johnsen","sequence":"first","affiliation":[{"name":"Biology Department, Duke University, Durham, NC 27708, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.
