The spar also carries an array of thermistors spaced at logarithmic intervals between a few mm below the surface to approximately 2 m depth. Atop the spar is a control system which continuously logs the thermistor data. The device is deployed from a vessel and allowed to drift away on a tether with a conductive core. Thermistor data are transmitted up the cable to a host computer on board the ship, while the control system allows for the remote firing of the sampling bottles by the host computer."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL0548" ; skos:note "accepted"@en ; skos:prefLabel "Plymouth Marine Laboratory Near-Surface Sampling Device"@en ; skos:related . skos:narrower . skos:narrower .
