"Metal or plastic insulated bottles with an approximate capacity of 1-2 litres designed for deployment on a cable, sealed by with a spring-loaded valve when triggered by dropping a weight down the cable. It was designed to recover an uncontaminated sample from depth within 0.01C of its in-situ temperature. The design is an improvement by Petterson in collaboration with Nansen on an original design by Nansen. Both designs are commonly known as Nansen bottles."@en . "accepted"@en .
