24 the next seven sections, which present the data from Legs Al, All, AIII, DI, DII, DIII and P respectively. 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 tracks. 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. Vertical profiles from the CTD's follow (except Leg P). Profiles of. temperature are staggered by 5C and those of salinity by 4 ppt. Isotherms for each transect are shown in the next pages, followed by isopleths of temperature, salinity and sigma-t, from the CTD's, when four or more casts were acquired along a transect. Based on instrument accuracy and the vertical temperature gradient, it is estimated that depths of isotherms in the main thermocline are uncertain to +2mn. The tick marks identify station positions and, again, the transect extremes are shown on these plots. Each section includes mean profiles of temperature from the XBT's. In addition, for all sections except 3 and 7, mean profiles of temperature, salinity and sigma-t from the CTD's are given, as well as a scatter diagram of the T-S pairs and the mean S(T) curve, with the + standard deviation envelope; the data presentation concludes with a plot of the mean N 2 (Brunt-Vaisala frequency squared) profile, with + the standard deviation. On the sigma-t and N2 plots, the appropriate profiles derived from the mean temperature and mean salinity profiles are also shown *-.....* ~..*..*.%** * *%

25 4 Al, All, and AIII were determined ashore..uring Leg P, when shallow (35m) Sippican AXBT's were deployed, the aircraft maintained an altitude of approximately 15 ft and an airspeed of 21 knots. The data were recorded on audio tapes. Station positions are accurate to within 1 km, temperature values to within.2*c and depth values to within 2% or 5 m (whichever is larger). DATA PROCESSING The processing of the AXBT data was carried out in Mr. Meredith Sessions' laboratory at Scripps using his audio-to-digital signal conversion system. The data were stored on magnetic tape and transferred to the IBM 333 at the Naval Postgraduate School where obvious noise spikes were edited from the profiles. The processing of cruise data, such as estimating depth profiles for the XBT temperature profiles based on the XRT's descent speed, and conversion of CTD conductivity to salinity using the algorithm given in Lewis and Perkin (1981), was carried out on the IBM 333. The data were then edited by removing obvious salinity spikes and eliminating cast failures that were not identified during the cruise. Approximately 96%, 97%, 1%, 97%, 99%, 99%, and 87%, of casts were retained in the data set of Legs Al, All, AIII, DI, II, DiII, and P, respectively. From a comparison of the CTD surface salinities with the surface salinities from the bottle samples it was determined that no correction to the CTD salinities was needed. The CTD data were interpolated to 5 m intervals and then up and down casts were averaged. The data have been transferred on digital tape to the National Oceanographic Data Center in Washington, DC. DATA PRESENTATION The cruise track, station locations (with XBT's, CTD's and AXBT's identified) and station numbers are shown in the first three figures of each of o 7 7. *

26 3 Leg P was carried out on 18 July aboard a USNR P3A aircraft, and sampled an e.,a approximately 25km square in the NOCAL area, as shown in Figure 68. On each cruise track, transect extremes are Identified by letter to aid in cross-referencing the data presented in subsequent figures. On each of these cruises, hydrographic stations were occupied at approximately 15 km along the track. For the AXBT flight, the along-track station spacing was about 35 km. DATA ACQUISITION Data acquired during OPTOMAll Legs At, All, AIII, DI, DII, and DIII include XBT and CTD profiles. Bucket surface temperature and water samples for salinity were taken at every CTD station. These surface values were used for calibration purposes as well as contributions to the data base. Legs AI, All, and AIII also acquired continuous 2 m thermosalinograph measurements, continuous meteorological data such as atmospheric pressure at a height of 2 m and wind speed and direction at a height of 2 m, and intermittent acoustic Doppler velocity data. The XBT data were digitized using a Sippican MK9 unit. The continuous "underway" data were digitized using an HP 5328 frequency counter and a 4 channel digital voltmeter. The continuous data were averaged over two-minute intervals. All data were recorded, using an HP 2 series computer, on data disks and transferred ashore to the IBM 333 mainframe computer for editing and processing. Station positions were determined by Loran C fixes and are claimed to be accurate to within about.1 km. Table I on page 6 summarizes the various sensors available on the R/V ACANIA and their accuracy. A Neil Brown CTD and Sippican XBT's were also used on the USNS DE STEIGUER; their accuracies are the same as stated in Table 1. The bottle surface salinity samples were determined by a Guildline Model 84 "Autosal" salinometer with an accuracy of +O.O3ppt. Samples from Legs DI, DII, and DIII were determined onboard; samples from Legs '

27 2 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 cruilses has been planned in two subdomains, NOCAL and CENCAL, shown in Figure 1. The six cruises and one AXBT flight comprising OPTOMAII were undertaken, during June, July, and August 1984, in the R/V ACANIA (Legs Al, All, AIII), the USNS DE STEIGUER (Legs DI, DII, DIII) and a Reserve Patrol Wing P3A aircraft (Leg P). Hydrographic data were acquired off the coast of California in an area which covered and extended the NOCAL region. The sampling was concentrated in a central 15km square domain centered about 19km off the -. coast between Pt. Reyes and Pt. Arena in the NOCAL domain. Leg Al was carried out from 5 to 15 June, Leg All from 21 June to 3 June - and Leg AIII from 5 to 13 July. These three legs sampled the central domain with additional transects to and from the domain, as shown in Figures 2, 13, and 24, respectively. Leg DI was carried out from 23 to 3 June, Leg DII from 3 June to 1 July, and DIII from 27 July to 5 August. Leg DI sampled areas to the north, south and inshore of the central domain, as shown in Figure 31. Leg DII sampled the central domain area with additional legs to the west and south of the area, as shown in Figure 43. Leg DIII, with an intensive sampling pattern which differed from the previous cruises, covered the central and inshore domains, as shown in Figure 56. o...
