Sunfish, Inc.

Sunfish spent 3 weeks with archaeologist Dr. @KellyMonteleone looking for submerged caves around AK's Prince of Wales Island that might contain evidence of ancient human habitation. We collected 3D sonar data from 22 sites, covering 640,000 m^2! @oceanexplorer📸Jason Gulley

@MKEWaterWorks Beautiful architecture!

Built in 1873, one of the original 3 @MKEWaterWorks facilities, along with the North Point Pumping Station and Kilbourn Reservoir.

We look forward to bringing SUNFISH to explore this region and learn more next summer. Our Submerged Past is funded by a NOAA Ocean Exploration grant and we've partnered with Sealaska Heritage Institute.

Early findings in the "Our Submerged Past" project are out. In May the team conducted a recce trip in SE Alaska, using sidescan sonar to search for potential underwater archaeological sites for SUNFISH to investigate in 2023. @oceanexplorer @SHInstitute tinyurl.com/2tmmayr3

Archaeologist Kelly Monteleone identified a fish weir at a depth of 50 m and estimates this human-made structure to be 11,000 years old! Much of the sea floor surrounding Prince of Wales Island was once exposed to the air and was home to some of the earliest people in N. America.

By comparison, traditional inspection methods for this kind of infrastructure require costly dewatering and months of system down-time.

We teamed up with @CollinsEngrInc to inspect a 7000' water tunnel for the city of Milwaukee! Sunfish completed a full imaging inspection of this tunnel in under a week while maintaining the high standards of water quality that are necessary when working with drinking water.

@SunfishAUV engineers & @BishopMuseum scientific divers will continue a collaboration to develop #SUNFISHAUV into an underwater robotic tool that will augment diver-based scientific #exploration and greatly expand the scope of ocean research activities possible today. #oceantech

Sunfish Inc is excited to be in Hawaii collaborating with the @bishopmuseum to test a new underwater robot that will augment diver-based exploration and ocean research as part of ongoing support from Schmidt Marine Technology Partners @SMTPSF. #oceantech #robotics #exploration

Next year SUNFISH will go to Alaska to learn more but for now: early findings from the Our Submerged Past project funded by @oceanexplorer, partnering with @shinstitute instagram.com/p/CifzOa8BvMu/…
