NARRAGANSETT, R.I. \u2013 January 21, 2010 \u2013 The bubbles in your champagne that appear to jump out of your glass and tickle your nose are exhibiting a behavior quite similar to the tiny bubbles found throughout the world\u2019s oceans, according to bubble physicist Helen Czerski. <\/p>\n


\nBut while the champagne bubbles are likely to raise your spirits, those in the ocean can cause clouds to form and affect the climate.<\/p>\n


\n\u201cBubbles are little packets of gases that rise or fall and can be carried around as if they\u2019re on little conveyor belts,\u201d said Czerski, a post-doctoral fellow at the 溏心vlog免费B站 Graduate School of Oceanography. \u201cThey carry carbon dioxide and oxygen from the atmosphere down into the ocean, and then when they go back up again they pop and sulfur compounds from marine plants are sent upward, forming particles in the air that lead to the formation of clouds.\u201d<\/p>\n


\nCzerski is studying how to detect and count ocean bubbles of different sizes to help scientists in other disciplines create more accurate models. She said that scientists have found it difficult to judge the effect of bubbles on their data for years and usually have had to add a \u201cfudge factor\u201d to account for them.<\/p>\n


\n\u201cFor instance, bubbles ring like bells when they are formed or when sound waves go past them, and if you\u2019re studying sounds traveling through the ocean \u2013 like sounds from whales or sonar \u2013 bubbles can get in the way of what you\u2019re trying to listen for,\u201d said Czerski, who earned a Ph.D. from Cambridge University before spending a year studying bubbles at Scripps Institution of Oceanography in San Diego and then moving to 溏心vlog免费B站.<\/p>\n


\n\u201cBubbles also scatter light strongly in the oceans and make things cloudy, so if you\u2019re studying light in the ocean you need to understand bubbles,\u201d she added.<\/p>\n


\nThe 溏心vlog免费B站 scientist uses an acoustical resonator to detect and count bubbles of different sizes in the water column. The device can detect bubbles from 3 to 170 microns in size, and she is assessing the accuracy and uncertainty in the measurements.<\/p>\n


\nShe recently used the resonator to collect bubble data near the Hawaiian Islands and in the Santa Barbara Channel off Southern California. She counts bubbles down to 10 meters deep \u2013 most bubbles don\u2019t go down much further than that, she said. The big ones float back to the surface while the smallest ones gets squeezed out by the pressure as they sink.<\/p>\n


\n\u201cJust after a wave breaks, there are loads of bubbles and they\u2019re changing really, really quickly,\u201d Czerski explained. \u201cThey\u2019re stretching and squishing and bumping into each other and breaking into smaller bubbles and they\u2019re doing it all too fast for us to see directly. Whenever they break up, each new bubble makes a \u2018ping\u2019 sound, and if you hear it you can say something about those new bubbles.\u201d<\/p>\n


\nCzerski said that understanding the physics of bubbles is increasingly important as climate models become more and more refined.<\/p>\n

\u201cWe need to study bubble distribution and where they go in the water column to understand the exchange of gases that they carry,\u201d she said.<\/p>\n


\nAccording to Czerski, while carbon dioxide and oxygen get carried into the ocean via bubbles, a chemical compound produced by phytoplankton gets carried out of the ocean via bubbles.<\/p>\n


\n\u201cNo one really knows why phytoplankton create dimethyl sulfide, but they do, and it passes into bubbles and is carried up and out,\u201d she said. \u201cThese bubbles supply sulfur to the atmosphere, which acts as a seed for cloud droplets to form.<\/p>\n


\n\u201cClimate is made up of a whole bunch of little things, including bubbles, and these little things matter because there are lots of them,\u201d Czerski said.<\/p>\n


\nCzerski began studying bubbles after earning a Ph.D. in a field she described as \u201cblowing things up,\u201d which included becoming expert at high-speed photography. She then looked for disciplines in which she could apply this knowledge.<\/p>\n


\n\u201cI\u2019ve always been fascinated by small things that do stuff that\u2019s too fast for us to see,\u201d she said. \u201cAnd I like building experiments that help us see those things.\u201d<\/p>\n


\nShe learned to scuba dive in order to deploy instruments for measuring bubbles, and she now believes that getting in the water is a vital step for any aspiring bubble scientist.<\/p>\n


\n\u201cYou can\u2019t really understand what\u2019s going on under the sea unless you go there yourself,\u201d Czerski concluded. \u201cThere is a huge benefit to directly experiencing the world you\u2019re studying. The rules are different down there.\u201d<\/p>\n
