Abstract
In the tropical and subtropical Atlantic Ocean loss of dissolved oxygen nearly always takes place within Nansen bottles between the time they close, in deep water, and the time the samples are drawn for analysis. The principal cause of this oxygen loss, in routine stations, is shown to be degassing; deep samples, rich in oxygen, are heated to above their saturation point as they are brought up through the thermocline and surface layers. Niskin bottles, which are better insulated, are immune from the fault. Examples of oxygen loss due to chemical reaction within the Nansen bottle and loss due, possibly, to bacterial respiration, are also described.
