Chemical Signatures Associated with the Freshening of Northern Atlantic Waters Between 1972 and 1981Further insight into the possible causes of the freshening of deep water in the northern Atlantic between the GEOSECS survey (1972) and the TTO survey (1981) is provided by measurements of dissolved silica and dissolved oxygen. As all the northern end member waters are low in dissolved silica content and high in dissolved oxygen content, the message carried by these chemical properties of silica has to do with the extent to which the waters in the northern Atlantic have mixed with the high silica content waters of Antarctic origin. A change in the degree and pattern of this intrusion is noted between the GEOSECS and TTO surveys.
