Now evidence of a drop in underwater noise pollution has led experts to predict the crisis may also be good news for whales and other sea mammals.<\/p>\n\n\n\n<p>Researchers examining real-time underwater sound signals from\u00a0<a href=\"https:\/\/www.oceannetworks.ca\/observatories\" target=\"_blank\" rel=\"noreferrer noopener\">seabed observatories<\/a>\u00a0run by Ocean Networks Canada near the port of Vancouver found a significant drop in low-frequency sound associated with ships.<\/p>\n\n\n\n<p>David Barclay, assistant professor of oceanography at Dalhousie University, the lead author of a paper reviewing the phenomena, examined sound power \u2013 a way of measuring \u201cloudness\u201d \u2013 in the 100 Hz range from two sites, one inland and one farther offshore. He found a significant drop in noise from both.<\/p>\n\n\n\n<p>\u201cGenerally, we know underwater noise at this frequency has effects on marine mammals,\u201d Barclay said.&nbsp;<\/p>\n\n\n\n<p>\u201cThere has been a consistent drop in noise since 1 January, which has amounted to a change of four or five decibels in the period up to 1 April,\u201d he said. Economic data from the port showed a drop of around 20% in exports and imports over the same period, he said.<\/p>\n\n\n\n<p>[ <a href=\"https:\/\/www.theguardian.com\/environment\/2020\/apr\/27\/silence-is-golden-for-whales-as-lockdown-reduces-ocean-noise-coronavirus\" target=\"_blank\" rel=\"noreferrer noopener\">click to continue reading at The Guardian<\/a> ]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>from The Guardian Silence is golden for whales as lockdown reduces ocean noise Curtailing of shipping due to coronavirus allows scientists to study effects of quieter oceans on marine wildlife by Karen McVeigh In cities, human lockdowns during the coronavirus pandemic have offered some respite to the natural world, with clear skies and the return [&hellip;]<\/p>\n","protected":false},"author":26,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"categories":[8],"tags":[],"class_list":["post-10654","post","type-post","status-publish","format-standard","hentry","category-weirdness"],"_links":{"self":[{"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/posts\/10654","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/users\/26"}],"replies":[{"embeddable":true,"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/comments?post=10654"}],"version-history":[{"count":0,"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/posts\/10654\/revisions"}],"wp:attachment":[{"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/media?parent=10654"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/categories?post=10654"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/bigjimindustries.com\/wordpress\/wp-json\/wp\/v2\/tags?post=10654"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
