File naming conventions:

    hc[X]yr-[Y]0-[Z]m.dat
     |  |  |    |  |  |  |  |
     |  |  |    |  |  |  |  the filename extension
     |  |  |    |  |  |  the label reffering to depth in meters 
     |  |  |    |  |  the lower depth of integration ('300','700' or '3000') 
     |  |  |    |  the upper depth of integration ('0' stands for the sea surface)
     |  |  |    ocean basins: w - World, p - Pacific, a - Atlantic, i - Indian 
     |  |  the label identifying that compositing period is [X]-year long
     |  anomaly type: 1 - for yearly, 5 - for pentadal 
     the label for heat content 

For example, file 'hc5yr-w0-3000m.dat' contains the time series of ocean pentadal
heat content of the 0-3000 m layer for the World Ocean

1st column - year+0.5 (for the yearly heat content) or mid-point
of five-year compositing period (for the pentadal heat content);
2nd column - time series of heat content of OB;
3rd column - time series of the standard error of heat content of OB;
4th column - time series of heat content of NHPB;
5th column - time series of the standard error of heat content of NHPB;
6th column - time series of heat content of SHPB;
7th column - time series of the standard error of heat content of SHPB.

The first line of file contains the labels for each of 7 columns.
Read the second line through the last line using an equivalent of the FORTRAN FORMAT
(F8.1, 6F8.3) statement.
