3.5 kHz and 'mowing the lawn'

The Vector is set to leave tomorrow (Saturday). I’m packed and ready to go, and ready to help load the ship Saturday afternoon. Weather forecast is for RAIN for the next five days off the west coast, so, lots of warm clothes and rain gear! Apparently I will be helping to gather data for 3.5 kHz – which has to do with sending sound waves (I think) to the bottom of the sea and back to then record the details. I will have to learn what that means very quickly. I did however learn that you don’t pronounce it “three point five” – it is “three and a half” J. I will also be ‘mowing the lawn’ which is terminology for doing multi-beam work that scans the ocean floor back and forth and gathers data. I would be thrilled to discover a ship wreck out there!!! Actually, in all honesty, I’m just thrilled that I get to be out there! Hoping that I'm not seasick, or that if I am it passes quickly!
