"Broadscale.h1" This is the top level file that lists the 1995 broad scale cruises. The pound (#) sign is used for comments which I have used to indicate the difference between Seabird and MK5 data. The next four lines show what will be found in each successive level down (h2-->h3-->data). The character ">" indicates a pointer to another file.
"eb5fctdn.h2" The .h2 file provides some variable ranges for the particular cruise: event #, time(gmt), time(local), lon, lat, casts, and sample depth. The site is the broad scale station grid. The naming convention of this file ("eb5fctdn") is NOT a requirement to properly serve your data but is a leftover naming convention used to indicate ship (e), consecutive cruise within a year (b5=2nd cruise of 1995), and instrument (fctdn=fisheries CTD, Neil Brown). The structure of this file was developed based on the 1992 - 1994 Georges bank cruises where there were many types of "events": towyos, mooring deployments, fine scale grids, and other process oriented work. Because the intent of the broad scale surveys is to occupy the same station grid, we consider the cruise a single event. This is not the case for the process cruises.
"eg1b5.h3" The .h3 file provides a record for each cast: yearday (both gmt and local), cast, station #, standard station #, water depth, long, lat, and datafile name. Again, this naming convention is not a requirement. This file is generated by running "ENDCRUIS.EXE" which is a fortran routine that reads in the cruise header file to do the year day conversion (note: this method considers January 1st at noon to be local year day 1.5).
"en61d001.prs" The .PRS cast files contain pressure, temperature, salinity, and fluorescence. The 1996 data will also contain light transmission data. The seabird CTD's do not have fluorometers or transmissometers on them. The .PRS files were generated without a text header at the beginning of the file. However, the routine that reads in these files (NMFS.C) looks for an underline and then skips a line before reading in the data. To account for this, I ran a read/write routine that simply adds a two line record to the top of each .PRS file.
****************
The final step is to create a ".objects" file that provides a pointer to your data (your .h1 file) that Bob Groman can use to put your data online.
