Instrument Description:

A device that collects an in-situ discrete water sample from any depth and returns it to the surface without contamination by the waters through which it passes, such as a water bottle.

PI supplied instrument name: oxycline sampling device
Dataset-specific description

Samples were collected at 7 depths across the oxycline using a syringe-sampling device that simultaneously fills a total of 28 syringes (4 syringes every 20cm vertically) using a mechanical feature that gradually pulls the water into the syringes when triggered.  In 2012, a new “oxycline sampling device” was developed that uses a multi-channel peristaltic pump to draw water from 8 depths across a 3m range.
