New Sonar Technology To Be Used in River Search
Authorities hope to soon locate the car of an Icelandic man who drove into the Ölfusá river just outside of Selfoss, South Iceland at around 10 pm on Tuesday night, RÚV reports. Nearly a hundred people participated in the search for 51-year-old Páll Mar Guðjónsson but so far, no sign of Páll’s car or any clues to its whereabouts have been found.
The initial search, which was made more difficult by strong winds and heavy rains, continued until close to 3 am on the first night, with an additional 100 people joining in before the evening was out. It continued on a smaller scale the next day, during which time, authorities also held a consultation meeting with multiple diving teams. Smaller spot-searches were also conducted on Thursday and Friday by boat and a larger-scale volunteer-run search is planned to take place over the weekend.
Meanwhile, after consulting with the diving specialists, searchers have decided that they will experiment with multibeam echosounder measurements over the riverbed, which will be taken in the ravine where the car entered the water and give them a clearer picture of the river depth as well as return point measurements.
This is the first time that this technology will have been used in a search here in Iceland, but searchers need to wait for the right weather conditions before they can proceed. Current weather forecasts suggest that it will be possible to take the multibeam measurements in the middle of the coming week, when there will be warmer temperatures and less precipitation.
