Instruments

CTD - profiler

Supplied Name: CTD Diver

Supplied Description:

The radon system is integrated with a CTD Diver (Van Essen) and logging GPS with depth- sounding capabilities.

Instrument Type

Generic Name: CTD - profiler

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/130/

Generic Description:

The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. The instrument is lowered via cable through the water column. It permits scientists to observe the physical properties in real-time via a conducting cable, which is typically connected to a CTD to a deck unit and computer on a ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast.

This term applies to profiling CTDs. For fixed CTDs, see https://www.bco-dmo.org/instrument/869934.

RAD-7 Radon Detector

Supplied Name: RAD-7

Supplied Description:

Rn in the lagoon surface waters were measured continuously using an automated pumping and sparging system connected to a suite of three RAD-7 detectors arranged with the counting cycles time-parallel for real-time in situ analysis (Burnett et al. 2001; Dulaiova et al.2005).

Radon concentrations in discrete samples of deep and shallow groundwater were measured on 250- ml grab samples using an additional radon-in-water (RAD-H2O) accessory (Durridge) to the RAD7 radon detector.

Instrument Type

Generic Name: RAD-7 Radon Detector

Acronym: RAD7

Generic Description:

The DURRIDGE RAD7 is a radon and thoron detector. The RAD7 is a computer-driven electronic detector, with pre-programmed set-ups for common tasks. It's built to withstand everyday use in the field. A rugged case encloses the detector, which is self-contained and self-sufficient. The RAD7 comes with a built-in air pump, rechargeable batteries, and a wireless infrared printer.
