Brian and Dan, two people from the Mechanical Engineering Department at UH Manoa, came out today to help me gather some data using their side sonar. It was a pretty cool device. From what I gathered, talking to Brian and Dan it measures depth based on intensity and time. Unfortunately it was low tide so we were limited by the area we could go to, even with the low tide limitations we were still able to cover a fair amount of ground on the motorized kayak. I’m excited to look at the data that was gathered!
I also got to meet Iris, who is the park manager at Kualoa Park. She and Ted helped set this all up for me and I greatly appreciate it. She set me up with a ride on a small sized sail boat to get all the way out to the channel. We got there in a few minutes, it was incredibly fun! On the sail boat I was able to get some GPS points of potential sites where fish would be located. Ikaika, the sailor/captain who took me out, told me a story how they once saw a 14 foot tiger shark. 14 feet! Iris also told me that Ulua also run threw the channel and that the channel was man made.
All this data will be helpful in my project at the end. I can tie in the sonar, WV2 imagery, GPS points, GIS layers, and UAV imagery (which I’ll get tomorrow) to create a map or build some sort of model to find/locate/predict archaeological features and artifacts.
