About the same size as a human diver would be, the robots can travel the oceans for months, communicating with their pilots as they journey, helping to create an underwater soundscape of the oceans of the world.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">UEA School of Environmental Sciences PhD researcher<\/span> <span style=\"font-weight: 400;\">Pierre Cauchy<\/span><span style=\"font-weight: 400;\">, who has been using these underwater marine robots for five years in the North Atlantic and Southern oceans and the Mediterranean Sea, corresponded with <\/span><i><span style=\"font-weight: 400;\">EM<\/span><\/i><span style=\"font-weight: 400;\"> about the research.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cWe use commercial robots and hydrophones,\u201d Cauchy explains. \u201cOur first experiments implied artisanal attachment of acoustic recorders (designed to be attached on marine animals) on the glider. Fully integrated sensors are now commercially available.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The aptly-named Seagliders move silently through water without propellers, in an unusual way.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cThey adapt their buoyancy using an oil bladder to either float or sink, as deep as 1,000 meters,\u201d details Cauchy. \u201cIt takes about 2 hours to dive from the surface to 1,000 meters (or to come back), during which they glide slowly, and without making any sound. This makes them very well-adapted to record the oceanic soundscape. Also, they\u2019re autonomous and can cover about 1,000 km during approximately 3 months without human intervention. They communicate via satellite, to send the data and take instructions.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Scientists can use <\/span><span style=\"font-weight: 400;\">the recordings<\/span><span style=\"font-weight: 400;\"> to measure sea-surface wind speed; listen to sounds made by whales, fishes and other marine life; monitor storms; and listen to noise created by human activities.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cI can observe physical processes such as wind speed, even during storms,\u201d Cauchy describes. \u201cI can monitor whale populations, and use the fish sounds to estimate their activity and health. I can measure shipping and industrial noise (for example, seismic surveys), to assess their impact on the marine life.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Recording this kind of sound with moving robots in remote areas without permanent weather stations allows scientists to glean more data on storm and wind patterns for fine tuning climate models.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cClimate models rely on in situ measurement for their calibration,\u201d remarks Cauchy. \u201cThe more and better in situ measurements they have, the better they are. Some areas, especially those with high seas, polar regions, piracy, or extreme weather conditions like hurricanes, are hard to monitor with a permanent weather station. A glider can go and make the needed measurements.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Next Cauchy and the team intends to take on rainfall rate measurements and ecosystems health monitoring with the help of the silent robots.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Now that Cauchy and others have shown that these silent swimmers can monitor underwater sounds from marine life to storms, these marine diving robots may soon be integrated into more areas of research. As the technology develops further, the marine robots may be capable of onboard\/real-time processing, and improved data transmission\u2014a real issue for acoustic recordings, which are big data producers.<\/span><\/p>\n<p><em><span style=\"color: #808080;\">Top image: An underwater ocean glider.
