The five CTD stations in at79.data were submitted to OCL on 28 August 2003 by Phil Mele, Lamont-Doherty Earth Observatory. They represent a clean version of five corrupted CTD stations submitted under accession number 9400167: at107080c.001, at107081c.001, at107083c.001, at107084c.001, at107085c.001. # R/V Atlantis cruise 107 Leg III, CTD data. 1.
