An even better match, to within 8 cm, was obtained by interpolating the total water level signal rather than interpolating the tidal and nontidal components separately. CSDL gained the capability of remotely accessing OPSD's water level data. Many of the U.S.'s historical water level records, as well as tidal constituents and datums, are accessible with the system. Two more presentations in CSDL's ongoing Seminar Series were held this month. His talk included many interesting historical images and drawings of previous heads of the Coast Survey and of field parties carrying out their duties in remote coastal areas.
Predictions account for channel depths and are tailored for specific ships.
Dr. Kurt Hess wrote a summary of his recent trip to Ankara to forward to Secretary Daley in preparation of his trip to Turkey. Dr. Gross will be taking over the lead of the research on this project. The memo recommends additional consistency checks and an improved format for documentation. Two possible techniques were discussed. This is important when attempting to predict the depth measurement uncertainties in different portions of the multibeam swath.
