INTRODUCTION This report presents moored temperature observations obtained at three buoys during the Joint Air-Sea Interaction Experiment (JASIN) of July through September 1978. Details of the JASIN project can be found in reports of the Royal Society (1977, 1978) and in a paper by Pollard (1978). In the present study, temperature was recorded at 10-minute intervals at depths ranging from 4.5 m to 81.5 m. Sea surface temperature and atmospheric conditions were also recorded at each buoy but will not be presented in this report. For a discussion and analysis of these observations, see Ishida (1980). Temperature observations using a towed thermistor chain have been obtained by Baumann et al. (1980) in the same general area as the moorings. INSTRUMENTATION The location of the four moorings B1 through B4 is given in Appendix A. The moorings each included two Aanderaa recorders and thermistor chains. At moorings B2, B3 and B4, eleven thermistors on shallow chains measured water temperature at vertical separations of 3 m from a depth of 5.5 m to 35.5 m. A loop in the cable at mooring Bl caused the shallow chain at this mooring to be 1 m more shallow than at the other three, so observations there were at vertical separations of 3 m from 4.5 to 34.5 m. The deep thermistor chain at all four moorings measured water temperature at 10 locations separated by intervals of 5 m from a depth of 36.5 to 81.5 m. The eleventh channel on the deeper chains was used to record pressure, but because of an apparent sensor malfunction, pressure observations have not been included in this report.
2 OBSERVATIONS The starting time and length of operation of each thermistor is given for buoys Bl, B2, and 84 in Appendix B. Observations from buoy B3 were extremely noisy and have been excluded from this report. Temperature observations for the remaining three moorings as a function of time are given in Appendix C. In general, the temperature plot from a given sensor was terminated at the point in time where it appeared to fail. In some cases, however, the exact location of the cutoff point was difficult to determine because the sensor apparently began giving erroneous readings several hours or even days before it totally failed. One obvious example of this occurred at mooring Bl. The 4.5 m thermistor seemed well correlated with the lower sensors during the first six hours of its operation, but at about 0100 on August 2 higher frequency oscillations ceased. While the observations continued to follow the general trend of the lower sensors, inversions appeared that were probably not real. Even so, these observations give an approximate indication of surface temperature at Bl and have not been excluded from the plots. Other examples of this occurrence are of much shorter duration but in most cases are just as obvious. One other problem with the data is that except for a few instances, the data loggers would not record lower than a certain value which was approximately 8.9 C. This malfunction appeared most obviously in frequent sharp cutoffs of the lower two sensors in the last three weeks of data from mooring B4. (For example, see August 17). The problem also occurred occasionally at B2 when temperatures fell low enough. Temperatures at 81 never fell below 9.09 C and no such cutoffs appeared.
