I am particularly interested in gas bubbles underwater, because these are the most powerful acoustical entities that occur underwater. Gas bubbles injected underwater sound notes \u2013 the smaller the bubble, the higher the note (just as a large wineglass emits a deeper note than a small wineglass when tapped with a spoon). Listening to these notes allows the measurement of bubble size. But like any object that can produce sound, bubbles vibrate sympathetically when sound of the correct pitch is projected at them: they emit notes in response, and can even implode (just as a certain voice can \u2018ring\u2019 and shatter a wine glass). An imploding bubble can damage its surroundings. This needs to be controlled as sometimes damage is desirable (as in ultrasonic tumour treatment) and sometimes it is not (e.g. during ultrasonic foetal scanning).<\/p>\n<p>I was asked to talk about how we use the sounds emitted by bubbles to locate gas leaks underwater. These can be either from naturally-occurring reserves of gas in the seabed, or be leaks of gas from undersea gas pipelines, or from carbon capture and storage facilities. However, as soon as I start talking about bubbles I wander off topic and I am bound to cover such questions as \u2018<strong>what does a waterfall sound like in space?<\/strong>\u2019 and \u2018<strong>do dolphins think nonlinearly?\u2019<\/strong><\/p>\n<p>Whenever sound in liquids is an issue, bubbles become an important and difficult consideration, so to work out the implications of the fundamental bubble physics I do, I must follow through to other disciplines. This means gaining expertise in other fields myself, and working with experts: with <strong>chemists<\/strong> in working out how to use sound with bubbles to make cold water clean as well as hot (so saving on electricity bills); with <strong>archaeologists<\/strong> to look at how sonar can be used to look at wrecks buried in muddy seabeds; with <strong>oceanographers<\/strong> with examine the possibilities of storing atmospheric carbon in disused oil reservoirs in the seabed; with <strong>medics<\/strong> to work out what is the safe level of ultrasound to give a pregnant woman\u2026 that sort of thing. Providing it is fun, and rigorous, I will get into that field.<\/p>\n<p>Multidisciplinary Research Week could be seen as making contacts for new funding opportunities, and these are important, but I see it primarily as <strong>having fun with curiosity<\/strong>\u2026 <strong>and curiosity with fun.<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p><strong>RSVP:<\/strong> <a href=\"http:\/\/multidisciplinaryweekbubble-eorg.eventbrite.com\/\" target=\"_blank\">http:\/\/multidisciplinaryweekbubble-eorg.eventbrite.com\/<\/a><\/p>\n<p>&nbsp;<\/p>\n<p><strong>For the latest news and events about the Multidisciplinary Research Week 2013, visit our Multidisciplinary Research website: <\/strong><strong><\/strong><\/p>\n<p><strong><span style=\"text-decoration: underline\"><a href=\"http:\/\/www.southampton.ac.uk\/multidisciplinary\">www.southampton.ac.uk\/multidisciplinary<\/a><\/span><\/strong><\/p>\n<p><strong>or follow us on\u00a0 \u00a0Twitter <\/strong><a href=\"http:\/\/www.twitter.com\/sustainscience\"><strong>@<\/strong><\/a><strong>MultiSoton #MDRWeek<\/strong><strong><\/strong><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong><br \/>\n<\/strong><\/p>\n<p>&nbsp;<\/p>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>Join Professor Tim Leighton for the keynote Lecture: The Acoustic Bubble on Wednesday 20th March to hear how acoustic sensors can also locate reserves of gas in the seabed.
