Late this morning we began surveying using the side-scan sonar attached to the starboard side of the boat and flying the CHIRP beyond the aft (backside) of the ship. Now we have our first depiction of the subsurface from the CHIRP as well as some detail of the surface features from the side-scan up. We are most interested in reflectors indicating recent changes in the subsurface (i.e, suture zones, sediment mass movement) which may pinpoint fault lines. Based on these features evdient in the CHIRP data, we have chosen areas to collect sediment, which will provide a more detailed record for recent seismic history in Haiti.
This afternoon, a group of geologists who have been working on shore met the Endeavor where we were able to deliver some onshore surveying supplies. Pictures of this reunion are included.
