Unfortunately, the abundance and distribution of seagrasses are declining rapidly worldwide due to growing anthropogenic pressures. Major seagrass restoration efforts have been made in recent years to help mitigate this decline, and habitat suitability models are often used to determine suitable restoration sites and guide these efforts. Solar exposure of the seagrass beds is one of the primary determinant of suitability but is often inadequately included in these models. We combine modeling, field optics, and remote sensing to determine the optimal benthic solar exposure conditions for seagrasses in dynamic, heterogeneous shallow coastal environments and help improve habitat suitability models and guide restoration efforts there.<\/p>\n<div class=\"bu-slideshow-container seagrass-habitat-suitability autoplay\" id=\"bu-slideshow-container-956\" data-slideshow-name=\"seagrass-habitat-suitability\" data-slideshow-delay=\"5000\" style=\"width: auto; height: 300px;\"><div class='slideshow-loader active'><div class='loader-animation'><\/div><p>loading slideshow...<\/p><\/div><div class=\"bu-slideshow-slides\"><ul class=\"bu-slideshow transition-fade\" id=\"bu-slideshow-956\"><li id=\"bu-slideshow-956_0\" class=\"slide \"><div class=\"bu-slide-container slide-caption-bottom-right\"><img src=\"\/fichotlab\/files\/2021\/01\/Screen-Shot-2020-12-30-at-08.48.36-e1609710720652.png\" alt=\"\" \/><div class=\"bu-slide-caption caption-bottom-right\"><p class=\"bu-slide-caption-text\">Improved habitat suitability map for eelgrass in the Plum Island Estuary in Massachusetts<\/p><\/div><\/div><\/li><li id=\"bu-slideshow-956_1\" class=\"slide \"><div class=\"bu-slide-container slide-caption-bottom-right\"><img src=\"\/fichotlab\/files\/2020\/12\/Screen-Shot-2020-12-30-at-08.48.15-e1609710581824.png\" alt=\"\" \/><div class=\"bu-slide-caption caption-bottom-right\"><p class=\"bu-slide-caption-text\">Modeled benthic solar exposure in the Plum Island Estuary in Massachusetts<\/p><\/div><\/div><\/li><li id=\"bu-slideshow-956_2\" class=\"slide \"><div class=\"bu-slide-container slide-caption-bottom-right\"><img src=\"\/fichotlab\/files\/2021\/01\/IMG_3260-scaled-e1609797219131.jpg\" alt=\"\" \/><div class=\"bu-slide-caption caption-bottom-right\"><p class=\"bu-slide-caption-text\">Optical profiler used to measure vertical UV and visible light attenuation in the water column<\/p><\/div><\/div><\/li><li id=\"bu-slideshow-956_3\" class=\"slide \"><div class=\"bu-slide-container slide-caption-bottom-right\"><img src=\"\/fichotlab\/files\/2021\/01\/27062-e1609711001857.jpeg\" alt=\"\" \/><div class=\"bu-slide-caption caption-bottom-right\"><p class=\"bu-slide-caption-text\">Seagrass restoration site in the Plum Island Estuary (exposed at low, spring tide)<\/p><\/div><\/div><\/li><li id=\"bu-slideshow-956_4\" class=\"slide \"><div class=\"bu-slide-container slide-caption-bottom-right\"><img src=\"\/fichotlab\/files\/2021\/01\/Screen-Shot-2021-01-03-at-16.44.30-e1609710946511.png\" alt=\"\" \/><div class=\"bu-slide-caption caption-bottom-right\"><p class=\"bu-slide-caption-text\">Plum Island Estuary in Massachusetts, a site of active seagrass (eelgrass) restoration efforts<\/p><\/div><\/div><\/li><li id=\"bu-slideshow-956_5\" class=\"slide \"><div class=\"bu-slide-container slide-caption-bottom-right\"><img src=\"\/fichotlab\/files\/2017\/05\/Screen-Shot-2017-05-23-at-16.16.47-e1609709960806.png\" alt=\"\" \/><div class=\"bu-slide-caption caption-bottom-right\"><p class=\"bu-slide-caption-text\">Seagrass meadow in Western Australia (Shark Bay)<\/p><\/div><\/div><\/li><\/ul><\/div><div class=\"bu-slideshow-navigation-container\"><ul class=\"bu-slideshow-navigation nav-icon\" id=\"bu-slideshow-nav-956\" aria-hidden=\"true\"><li><a href=\"#\" id=\"pager-1\" class=\" active\" aria-hidden=\"true\"><span>1<\/span><\/a><\/li> <li><a href=\"#\" id=\"pager-2\" class=\"\" aria-hidden=\"true\"><span>2<\/span><\/a><\/li> <li><a href=\"#\" id=\"pager-3\" class=\"\" aria-hidden=\"true\"><span>3<\/span><\/a><\/li> <li><a href=\"#\" id=\"pager-4\" class=\"\" aria-hidden=\"true\"><span>4<\/span><\/a><\/li> <li><a href=\"#\" id=\"pager-5\" class=\"\" aria-hidden=\"true\"><span>5<\/span><\/a><\/li> <li><a href=\"#\" id=\"pager-6\" class=\"\" aria-hidden=\"true\"><span>6<\/span><\/a><\/li> <\/ul><\/div><div class=\"bu-slideshow-arrows\" id=\"bu-slideshow-956_arrows\"><a class=\"bu-slideshow-arrow-left\" href=\"#\"><\/a><a class=\"bu-slideshow-arrow-right\" href=\"#\"><\/a><\/div><\/div>\n<table class=\" aligncenter\" style=\"width: 100%; height: auto; background-color: #e6e6e6;\">\n<tbody>\n<tr>\n<td style=\"text-align: right;\"><span style=\"text-decoration: underline;\">Current Related Grants:<\/span><\/td>\n<td><span style=\"color: #000000;\">&#8230;<\/span><\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: right;\"><span style=\"text-decoration: underline;\">Recent Related Publications:<\/span><\/td>\n<td><a href=\"https:\/\/doi.org\/10.1029\/2020GL088362\"><\/a><a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0048969721065591\"><span style=\"color: #000000;\">Cronin-Golomb et al.
