Using a chain saw, a three by three meter hole was cut in the ice. A cage was then placed in the hole to catch the AUV for recovery after the mission. The AUV is equipped with sensors to measure, salinity, temperature, oxygen, chlorophyll, disolved organic matter, side scan sonar and a multibeam echosounder for measuring ice-thickness.
To assist during the tests, the Blueye Pioneer underwater drone provided a valuable view under the ice. The first under ice deployment for the Blueye Pioneer was successful, the vehicle operated great in the cold water. Both in terms of thrust power, battery performance and robustness the Pioneer did a great job.
The team from AUR-Lab expects more challenging conditions on Svalbard at latitude 78-N in the last week of April. Working in the Arctic, low logistics solutions like the Pioneer simplifies underwater and under ice operation.
