Of course, Perl is perfectly suited for this kind of tasks!

use Modern::Perl '2014';

my @data;
<DATA>;    # discard header line
while (<DATA>) {
    chomp;
    last if $_ eq 'END PARAMETERS';    # end of data marker, not neces
+sary if reading from a file
    my ( $station, @fields ) = split /,/;
    $data[$station] = \@fields;
}
<DATA>;                                # discard header line
while (<DATA>) {
    chomp;
    my ( $station, $level ) = split /,/;
    say
"Station $station: salinity $level is $data[$station][$level-10] and t
+emperature $level is $data[$station][$level-4]";
}

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
