    R/V Star Hercules Cruise: Trident Jason project data log 2
    (Woods Hole Oceanographic Institution, 1989) Gegg, Stephen
    The following lists actual and relative positions for 2 critical pieces in the AMPHORA Site- the WRECK and the BROKEN AMPHORA. First, some comments. All LAT/LON positional data are referenced to GPS. The actual positions from the STARELLA 88 data are reliable. The actual position (only located the broken AMPHORA on that trip) from the KNORR 88 data is not reliable for reasons which are detailed in a separate note to Tom Crook. In which case, the relative positions are important.

    AMPHORA Site Important Positions - Memorandum
    (Woods Hole Oceanographic Institution, 1989-04-14) Gegg, Stephen
    The following lists actual and relative positions for 2 critical pieces in the AMPHORA Site - the WRECK and the BROKEN AMPHORA. First some comments. All LAT/LON positional data are referenced to GPS. The actual positions froM the STARELLA 88 data are reliable. The actual position (only located the broken AMPHORA on that trip) from the KNORR 88 data is not reliable for reasons which are detailed in a separate note to Tom Crook. In which case, the relative positions are important. From the relative positions of the 2 wreck locations, one can safely say that there is only one wreck in that area. The broken AMPHORA is the only tie between the two coordinate systems. This is assuming that there is only one, unique broken amphora. Uchupi believes this is the case. However, the possibility that there is more than one has not been completely ruled out. Considering the proximity of the wreck to the broken amphora based on the STARELLA 88 data, it seems implausible that you would have Missed the wreck completely once you found the broken amphora. This is what preserves the possibility of more than one, at least for the Moment. More careful and detailed examination of the KNORR 88 data tracks should indicate if you indeed went through an area located relative to the broken amphora where the wreck should have been. I haven't had time to examine the data myself yet.
