Telemetry has significantly enhanced our capacity to predict and plan in the face of climate change and human influence,&rdquo; said Sara Iverson, scientific director of the Ocean Tracking Network and corresponding author on the paper.<\/p>\n<h2>Telemetry reveals hidden lives of marine animals<\/h2>\n<p>Acoustic and satellite telemetry studies are being combined with other biological measurements like genetic analysis or physiological status. These data help determine drivers behind animal behavior to forecast how anthropogenic and climate changes will affect species and populations.<\/p>\n<p>&ldquo;At <abbr>HIMB<\/abbr>, we have used these techniques to reveal the unexpectedly wide range of movements of tiger sharks in the islands and demonstrate how yellowfin tuna (ahi) keep warm during deep dives into cold water,&rdquo; said Holland.<\/p>\n<p>Further, telemetry data have revealed the often-mysterious migrations of endangered marine animals like leatherback turtles, basking sharks, European eels and Pacific bluefin tuna.<\/p>\n<h2>A new way to manage ocean resources<\/h2>\n<p>These discoveries, and the increasingly sophisticated technology behind them, generate critical knowledge towards conservation recommendations. Tracking studies also pinpoint successes and limitations of current management plans. For example, acoustically tagged reef fish were shown to regularly move outside their Marine Protected Area, putting them at risk.<\/p>\n<p>&ldquo;In the future, we could be looking at spatially dynamic <abbr>MPA<\/abbr>s, which move annually with predictions of animals&#8217; response to their environments,&rdquo; said Nigel Hussey, lead author and researcher at the University of Windsor with the Ocean Tracking Network.<\/p>\n<p>Aquatic animal movements and migrations transcend geopolitical, economic, and management boundaries. Telemetry studies in the last decade have documented movement over transoceanic scales, to regions unreachable by humans, and into some of the harshest parts of the ocean, providing the groundwork for &ldquo;next-generation aquatic governance frameworks.&rdquo;<\/p>\n<p>&ldquo;The ocean will continue to change,&rdquo; said Hussey. &ldquo;Global collaboration\u2014among industry and science sectors, and researchers themselves\u2014is imperative to get ahead of these changes before they catch up to us.&rdquo;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Electronic tagging of aquatic animals has had a huge impact on recent marine discoveries, according to new paper co-authored by <abbr>UH<\/abbr> M&#257;noa researcher<\/p>\n","protected":false},"author":16,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[30],"tags":[53,175,262,107,9],"class_list":["post-36023","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-research","tag-hawaii-institute-of-marine-biology","tag-marine-biology","tag-marine-science","tag-oceanography","tag-uh-manoa","entry","has-media"],"aioseo_notices":[],"jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/posts\/36023","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/users\/16"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/comments?post=36023"}],"version-history":[{"count":10,"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/posts\/36023\/revisions"}],"predecessor-version":[{"id":146453,"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/posts\/36023\/revisions\/146453"}],"wp:attachment":[{"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/media?parent=36023"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/categories?post=36023"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/tags?post=36023"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
