Wormley IAPSO seawater ampoules contain standard seawater with a "known" salinity value. The label on the IAPSO vial shows the "Date" on which the IAPSO batch was made, the K15, 2 x K15, and the salinity value. IAPSO ampoules are used as universal standards when measuring salinity samples. Table 6 below shows the IAPSO batches used for HOT cruises 1-157. HOT-21 (November 17-18, 1990, Chief Scientist C. D. Winn) is excluded from this table because the crane on R/V Naina was too long for a safe deployment of the CTD and the cruise was aborted due to increasing seas and gale force winds.
