We were out on our first field day for a NFWF-funded project we call "ScanPot." We're quantifying the efficiency of using sidescan sonar to identify lobster pots on the seafloor in flat-softer bottom (low backscatter) and rough-harder bottom (high backscatter). We're partnering with a commercial lobsterman on the project and using his boat.
We're using a Klein3000 200/355 kHz sidescan we borrowed from the wonderful folks at MIT Seagrant. We collect data onto a laptop running SonarPro v. 12. We collected both the high and low resolution imagery, but only looked at the high resolution imagery on the survey.
We were hoping to image the pots at a 75 meter range, but beyond 50 meters the resolution was too compromised. So we'll have to do our full surveying at a 50 meter range.
