Parameter list
Physics: Secchi Disk visibility depth
Description:
*Data file(s): AV23_1wd.dat
*Format: Header data file format of the NATO TU-BS project.
*Ship (station) name: Akademik Vernadsky (MHI, Ukraine).
*Expedition: Cruise number 23_1.
*Parameters: Secchi disk depth, meters, Forel-Ule scale, grade
number.
*Instruments and methods: Standard Secchi disk (diameter 0.3 m)
was used with a wire winch from the 5 m height desk. Standard
Forel-Ule scale (21 color samples) was used for determination
of the water color comparing the color of the scale and the
color of the sea water column above the Secchi disk at the 1/2
of its visibility depth.
*Accuracy: The error of the depth determination is approximately
0.5 m.
*Processing (if applied): Corrections were made on the wire angle.
*Principal investigator(s): Viktor I.Fedirko (MHI, Sevastopol,
Ukraine).
*Digitization: Double-key entry at the MHI (Sevastopol, Ukraine)
in September, 1993. Responsible - Dr. A.V.Mishonov.
*Remarks: Data are obtained by qualified stuff and are reliable.
*Completed by: Alexey V.Mishonov (MHI, Sevastopol, Ukraine).
*Date: 19.03.1996.
*Source of data: MHI NASU, Ukraine
