ac-9 data: The sampling rate for the ac-9s was once per hour. Column format for *.txt files are located in the header. Units for a, b, and c are 1/m. The following corrections have been made to the ac-9 data:
1) Scattering correction, e.g., a(412)=a(412)-0.14*(b(412)).
2) a(715) has been subtracted from all wavelengths.
NOTE: Temperature correction has been applied to a(715) and NO salinity correction has been applied to these data.

ADCP data: The ADCP sampled 16 times per hour at bin depths every 2 meters between 8 and 60 m. Column format for the *.txt files is as follows:
(1) Time
(2-28) u- or v-velocity at bin depths every 2 meters from 8 m to 60 m.
Units for u and v velocity are cm/s.

Beam c data: Beam c data were sampled eight times per hour. Column formats for the *.txt files are located in the header. The wavelength for the transmissometer is 660 nm. Units for the beam c data are 1/m. Beam c data were calibrated against c(650) data from the ac-9 (r2s were above 0.9).

BIOPS Temperature data: BIOPS temperature data were sampled eight times per hour. Column format for *.txt files are located in the header. Units for temperature are degC.

Fluorometer data: Fluorometer data were sampled eight times per hour. Column formats for *.txt files are located in the header. Units for chlorophyll-a data are ug/l. Chlorophyll-a was derived from fluorescence using factory calibrations and compared with chlorophyll-a determined from ac-9 data using the following relationship derived from Shifrin [1988]:
1) a*sp(676)=2.46E-02
2) a(chl)=a(676)-[a(650)+a(715)]/2
3) chl-a=a(chl)/a*sp(676)

Lu(683) data: Lu(683) data were sampled eight times per hour. Column format for *.txt files are located in the header. Units for Lu(683) are uE/m^2/s.

PAR data: PAR data were sampled eight times per hour. Column format for *.txt files are located in the header. Units for PAR are uE/m^2/s.

Seacat data: Seacats sampled 16 times per hour. Column formats for the *.txt files are located in the header. Units for temperature is degC. Units for salinity are psu

Tidbit data: Tidbit data were sampled once every 24 minutes. Column formats for the *.txt files are located in the header. Units for temperature are degC.

TPOD data: TPOD data were sampled 16 times per hour. Column formats for the *.txt files are located in the header. Units for temperature is degC.
