by This is our 2nd full day at sea, though most of us are counting this as our first since most of us were seasick yesterday. Today we analyzed CTD data from a previous deployment, looking at conductivity, depth, and temperature. We created charts and analyzed the water at different depths, from these charts we then discussed the waters history! Today we also had a lecture by John Desanto on seafloor geodesy. John informed us about offshore deformation and ways to measure it. He focused on measuring the seafloors movement by acoustic GPS using a glider. Later in our expedition John is going to drop a glider into the ocean, which sends out signals to transducers placed in groups and collects pings from them. When the glider does this, it marks a spot where all the pings correlate to. Eventually after sending the glider to the same site multiple times it shows how the ocean floor is moving by looking at the change in spots where the pings correlate to. This was super cool to hear about and I can’t wait to see the glider get launched!
I’m going to sign off now and head back up to the “Steel Beach” where I will lay in the sun and look for wildlife.
See you in Alaska,
Kelly
