It took us several years to really come up with an operational system that was user friendly.\u201d<\/p>\n<p dir=\"ltr\">Guigand said the team began by developing a benchtop system to photograph plankton. When regular photography methods could not produce consistently discernible images of zooplankton, they turned to shadowgraghy, a method used to photograph fast-moving objects in ballistic analysis.<\/p>\n<p dir=\"ltr\">Instead of capturing light reflecting off the plankton in a camera, the method captures shadows. For the bench top model, a blue LED light shines through a lens and into a tank of plankton. The plankton cast shadows captured by camera, resulting in a detailed images of the creatures that are inverted to show plankton in white on a black background.<\/p>\n<div id=\"attachment_15148\" style=\"width: 430px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-15148\" class=\"size-full wp-image-15148\" alt=\"A zooplankton species image captured by the ISIIS of the coast of Southern California (Credit: Bob Cowen \/ University of Miami &amp; Oregon State University)\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2013\/10\/PlanktonPortalFeatured.jpg\" width=\"420\" height=\"470\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2013\/10\/PlanktonPortalFeatured.jpg 420w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2013\/10\/PlanktonPortalFeatured-268x300.jpg 268w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2013\/10\/PlanktonPortalFeatured-200x224.jpg 200w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2013\/10\/PlanktonPortalFeatured-300x336.jpg 300w\" sizes=\"auto, (max-width: 420px) 100vw, 420px\" \/><p id=\"caption-attachment-15148\" class=\"wp-caption-text\">A zooplankton species image captured by the ISIIS of the coast of Southern California (Credit: Bob Cowen \/ University of Miami &amp; Oregon State University)<\/p><\/div>\n<p dir=\"ltr\">The same technology was then incorporated into ISIIS with help from\u00a0oceanic tow body and instrument housing company BellaMare. Two pontoons house a camera on one side and an LED light on the other. Lenses focus the camera and light, and a pair of mirrors make sure everything connects. Plankton floating between the pontoons are photographed as they go about their daily lives.<\/p>\n<p dir=\"ltr\">Water quality data is also collected simultaneously for parameters such as dissolved oxygen and chlorophyll. \u201cUsually you can see the physical signature of the water masses you cross, (like) changes in temperature, salinity, but also a biological\u00a0change in the community of observed organism,\u201d Guigand said. \u201cYou may see the accumulation of certain plankton in frontal zones, where two water masses\u00a0meet each other.\u201d<\/p>\n<div id=\"attachment_16360\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-16360\" class=\"size-full wp-image-16360\" alt=\"The In Situ Ichthyoplankton Imaging System, or ISIIS, on deck (Credit: University of Miami)\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2014\/01\/ISIISBodyDeck.jpg\" width=\"600\" height=\"464\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2014\/01\/ISIISBodyDeck.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2014\/01\/ISIISBodyDeck-300x232.jpg 300w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><p id=\"caption-attachment-16360\" class=\"wp-caption-text\">The In Situ Ichthyoplankton Imaging System, or ISIIS, on deck (Credit: University of Miami)<\/p><\/div>\n<p dir=\"ltr\">One mission in 2010 in the Pacific\u2019s Southern California Bight netted so many images that researchers had to ask the public for help.
