INTRODUCTION The OPTOMA (Ocean Prediction Through Observations, Modeling and Analysis) Program, a joint NPS/Harvard program sponsored by ONR, seeks to understand the mesoscale (fronts, eddies, and jets) variability and dynamics of the California Current System and to determine the scientific limits to practical mesoscale ocean forecasting. To help carry out the aims of this project, a series of cruises has been planned in two subdomains, NOCAL and CENCAL, shown in Figure 1. The cruise 0PT0MA1 was undertaken, on the R/V ACANIA, in March, 1982 and covered part of the NOCAL domain which is roughly 200 km square centered 150 km off the California coast. From March 8 to 13, hydrographic data were acquired along the tracks shown in Figure 2. In the rectangular domain, roughly 90 km across-shore by 120 km alongshore, the series of parallel transects directed alongshore were separated by about 18 km. Along-track station spacing was about 8.8 km. In addition, there were tracks to and from the domain. DATA ACQUISITION During 0PT0MA1 XRT profiles, bucket surface temperature and water samples for salinity were taken at every station. Continuous 2 m thermal sal i nograph measurements and meteorological data such as atmospheric pressure at a height of 2 m and wind speed and direction at a height of 20 m were also recorded. The XBT profiles were recorded as analogue traces. The continuous "underway" data were digitized using an HP 5328 frequency counter and a 40 channel digital voltmeter, averaged over one-minute intervals and recorded, using an HP 9835 computer, on data cassettes. Station positions were determined by Loran C fixes and are claimed to be accurate to within about 0.1 km. The probe on the Sippican Expendable Bathythermograph (XBT) has an accuracy of jH).2C in temperature and +2% or 4.6 m (whichever is greater) in depth. The 2 m underway sensors are from SEA-BIRD Electronics. The temperature sensor, a glass-coated thermistor bead, has an accuracy of jf0.003C; the conductivity sensor, a two-terminal flow-through electrode cell, has an accuracy of +0.003 mmho/cm. -2- The surface salinity from the bottom samples were determined ashore by a Guildline Model 8400 "Autosal" salinometer with an accuracy of +0.003 ppt. The Table on page 4 summarizes the various sensors available on the R/V ACANIA and their accuracy. DATA PROCESSING The XBT traces were digitized at the surface and points of inflection to an accuracy of 0.01C by Fleet Numerical Oceanography Center (FN0C). These data were then transferred to the IBM 3033 mainframe at the Naval Postgraduate School and edited by removing obvious cast failures that were not identified during the cruise or digitization procedure. Approximately 96% of casts were retained in the data set. The data have been transferred on digital tape to the National Oceanographic Data Center in Washington, DC. DATA PRESENTATION The cruise track, station locations and station numbers are shown in the first three figures of the next section. These figures are followed by a listing of the stations, with their coordinates, the date and time at which the station was occupied, and the surface information obtained at the station. Vertical profiles of temperature from the XBT casts are shown in staggered fashion. The location of these profiles may be found by reference to the various maps of the cruise track. Transect extremes are identified as nearly as possible. The first profile on each plot is shown with its temperature unchanged; to each subsequent profile an appropriate multiple of 5C has been added. Isotherms for each transect are shown in the Figure 6. Based on instrument accuracy and the vertical temperature gradient, it is estimated that the depths of isotherms in the main thermocline are uncertain to _+20m. The tick marks identify station positions and, again, the transect extremes are shown on these plots. The data presentation concludes with a plot of mean and + standard deviation profiles of temperature from XBT's. -3- SCIENTIFIC INSTRUMENTS ABOARD THE R/V ACANIA Instrument Variable Sensor Accuracy Resolution Neil Brown pressure strain gage CTD temperature thermistor Mark Illb conductivity electrode cell 1.6 db 0.025 db 0.005 C 0.0005 C 0.005 mmho 0.001 mmho Sippican temperature thermistor BT depth descent speed 0.2 C max. of 4.6 m and 27o of depth Guildline Autosal conductivity electrode cell 0.003 ppt 0.0002 ppt Amatek Straza ADVP velocity profiles to 100m 4 beam sonar 3 cm/sec relative to ship speed 3 cm/sec Rosemount sea surface platinum Sensor temperature thermometer 0.05 C 0.005 C Sea-Bird temperature thermistor Sensors conductivity electrode cell at 2 meters 0.003 C 0.0005 C 0.003 mmho 0.0005 mmho Rosemount Sensor air temperature thermometer 0.01 C Kavolico Barometer atmospheric pressure pressure transducer 1.5 mb 0.1 mb 1200 EPS Hygrometer dew point condensation temp, sensor 0.2 C 0.02 C Meteorology Res.
