Me rigging the sonar tool off the side of a skiff, while boat operator holds onto the back of my life jacket

Collecting sonar data

Collected some great data in Lake Powell last week!
#ColoradoRiver #SanJuanRiver #MultibeamSonar

As we explore #IronBottomSound, we're using @unhresearch.bsky.social's #USVDriX to create a high-resolution map of the entire basin and identify potential exploration sites. #DriX has an EM712 #multibeamsonar and topside sensors to support piloting from both shoreside and onboard #EVNautilus.

Multibeam sonar image of Bouldnor Cliff, a preserved 6060-5880BCE preserved landscape at 10 m depth in the Solent. Lobsters and eels dog lithics out of the cliff face

Image showing the diving conditions at Bouldnor. Basically it is green and you can't really see anything because the visibility is so poor

An assemblage of stone tools recovered from a preserved landscape submerged in the Solent. Some nice scrapers there.

#NauticalArchaeologySociety conference day two starts with Garry Momber talking about New Forest waterways. Starting off with the first #MultibeamSonar #MBES data of the conference, covering Bouldnor Cliff as well
