Description

MIDAS (Multiple Instrument Data Acquisition System) is the ship's underway data acquisition system. Water flows through the system pumped from approximately one meter below the surface passing by sensors that measure various water quality parameters like temperature, salinity, chlorophyll, and turbidity.

Methods & Sampling

A real time graphical display provides charting and data display to the ships two labs as well as anywhere else on the ships network. Navigational data is acquired from a Starlink differential GPS or a Trimble GPS with a Micronet Receiver Station. The Micronet Receiver Station is a land based differential system privately maintained (provided for LUMCON’s use by Doug Chocrane Technologies, Lafayette, Louisiana), with sub 5-meter accuracy and available out to 300 miles in the Gulf of Mexico. A sea water flow-through system provides sea surface temperature, conductivity, chlorophyll fluorescence, and transmissometry data using: a Sea-bird Electronics SBE 21 Thermosalinograph; a Sea-Bird Electronics SBE 38 Remote Digital Immersion Thermometer; Turner Designs Model 10 Series Fluorometers; and a WETLabs 10 centimeter or 25.0-centimeter path length transmissometer. MIDAS also integrates the data from the ships meteorological suite into the data set and display. The meteorological suite consists of a R.M. Young 05103 Wind Monitor, a R.M. Young model 61201 Barometric Pressure sensor, a R.M. Young TS05327 Temperature and Relative Humidity sensor and photo synthetically active radiation (PAR) is measured with a LI-COR LI-190SZ Quantum Sensor.

Generic Name: Global Positioning System Receiver

Acronym: GPS

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/POS03/

Generic Description:

The Global Positioning System (GPS) is a U.S. space-based radionavigation system that provides reliable positioning, navigation, and timing services to civilian users on a continuous worldwide basis. The U.S. Air Force develops, maintains, and operates the space and control segments of the NAVSTAR GPS transmitter system. Ships use a variety of receivers (e.g. Trimble and Ashtech) to interpret the GPS signal and determine accurate latitude and longitude.

Multiple Instrument Data Acquisition System

Supplied Description:

MIDAS is a PC based Multiple Instrument Data Acquisition System (MIDAS) controlled by a rack mounted dual processor Digital Server 3000R with 21" monitor, and 10 gigabyte hard drive. A National Instruments 16 port serial expansion board allows modular integration of instrumentation, rapid sampling rates, and the maintenance of a real-time data display. Analog sensor signals are converted to a serial format for output to the host PC using using R.M. Young A/D devices. The controlling software was developed using National Instruments LabVIEW, to allow accessibility and ease of modification.
