The focus has been on the physical processes that allow materials to cross the coastal margin and enter the open lake. From May 1998 - May 2001 the Applied Physics Laboratory, University of Washington and the Large Lakes Observatory, University of Minnesota, Duluth conducted a series of four cruises based on coordinated use of moored instruments and shipboard ADCP and CTD surveys. The data reported here constitute the velocity and temperature records collected by the University of Washington during those three field years.

The Decimalday or Julianday field on the right in both formats is actually the decimal day of the deployment year. 10) Data collection problems: During the 1998 mooring year, the Aanderaa current meters were found to have been deployed with batteries that affected the magnetic compass. A supplementary compass calibration of each sensor with these batteries was performed, and applied in the form of a computer lookup table. The latter technique was found to more accurately represent the standard calibration than a fitted polynomial, and was also used for the 1999 and 2000 data. Among the 26 instruments deployed during the three years, we found three instruments with such severe problems in their data records that we have been unable to resolve them satisfactorily enough to include the data in the archive. The three instruments, with a brief summary of the nature of their problems, are described in a separate text file: Problems.txt 11) Other related data sets: Information on related moored and hydrographic data obtained by the Large Lakes Observatory can be obtained from Dr. Elise Ralph (eralph@d.umn.edu). 12) Conditions for use or citation: Data freely available Please, as a courtesy, contact the PIs before using these data 13) Data qualifications or warnings: RCM data - standard Aanderaa limitations apply - estimated accuracy 2 cm/s in speed, 5 deg in direction, 0.05 degrees C in Temperature 14) Grant numbers: NSF grant number OCE-9712846 15) Sample repository locations: Not applicable ================================================================= FILE AND DIRECTORY LISTING ================ - 24 data files - 2 readme files KITES.txt (this file) Problems.txt Name Size/bytes 1998: 98-6548.txt 815130 98-11136.txt 813360 98-7832.txt 817543 98-3169.txt 813404 98-7036.txt 389492 98-7037.txt 817456 1999: 99-1926.txt 1544793 99-6545.txt 1545800 99-1315.txt 1544740 99-1923.txt 1544794 99-6549.txt 765802 99-6919.txt 1544816 99-1314.txt 1544762 99-6544.txt 765765 2000: 00-6543.txt 729768 00-2243.txt 729768 00-11454.txt 726672 00-6547.txt 728392 00-3169.txt 629319 00-11136.txt 728392 00-11456.txt 728395 00-6498.txt 728392 00-523.txt 685954 ------------------------------------------------------------------- End-of-text-file --------------------------------------------------------------------- Name: Problems.txt Problems.txt Type: Plain Text (text/plain) Encoding: base64 Name: KITES.txt KITES.txt Type: Plain Text (text/plain) Encoding: base64
