This system serves as the central data collection point for all data taken aboard the ship. Data display is Web browser based. All monitored parameters can be displayed on any computer with a web browser. Data is written and transferred to the user at the end of the cruise on an ISO-9660 CD-ROM or on IBM PC compatible floppy disks. Two Windows NT servers communicate via ETHERNET and form the hub of the system. The network employs fiber-optic and copper based switched FAST ETHERNET and fiber-optic and copper based ETHERNET. TCP/IP and NETBEUI protocols are employed on the network. Terminal and ETHERNET connections are provided in the labs and staterooms. Network file and printing services for IBM compatible PCs and UNIX computers are provided. A variety of programming languages are available for users to develop software specific to their needs. Users are encouraged to bring their own software for their specific applications.* * * * · *Hardware Configuration * · One Pentium 400 MHz NT Server (Primary Domain Controller) · 256 megabyte memory · 24 gigabyte RAID disk space · CD ROM Drive · One Pentium 400 MHz NT Server (Backup Domain Controller) · 256 megabyte memory · 24 gigabyte RAID disk space · CD ROM Drive · One Pentium 400 MHz NT Server (Data Processing/ CDROM Burner) · 256 megabyte memory · 9 gigabyte disk space · 70 Gigabyte DLT Drive · CD ROM Recorder · CD ROM Drive · One Pentium 400 MHz NT Server (Data Collection Computer) · 256 megabyte memory · 9 gigabyte disk space · CD ROM Drive · HP CD ROM Server · CD ROM Drives (7) · Printers and Terminals · Lexmark 1250 OptraS Network Postscript printer · Epson Stylus 3000 Large format color injet printer · Personal Computers · In addition to various PCs aboard the ship for controlling MTG supplied instruments there is always at least one Pentium II 300 MHz based PC (9 gigabyte hard drive, 3.5" FDD) for general use by the scientists. · Software Configuration · Operating Systems · Windows NT Server 4.0 (or most current version) · Windows 2000 (or most current version) · Programming languages and software · Maptech - Ship track plotting · Labview - Display and logging software · MS Office 2000 · Word - Word-processing · Excel - Spreadsheet · Access - Database · Power Point - Presentation · MATLAB* * · *Underway Data Collection Parameters* · Differential Global Positioning System (GPS)-- Ship's position is taken from both the Ashtec 3D GPS and MX 300 GPS systems. · Ship’s attitude; pitch, roll, heading is taken from the Ashtec 3D GPS · Ship’s Speed--Ship’s speed is taken from the ship's Sperry Doppler Speed log. Speed is resolved to a tenth of a knot. · Gyrocompass-- The ship's gyro heading is taken from the synchro output of the ship's gyrocompass and is resolved to 0.1 degrees. · Wind Speed & Direction · Primary wind speed is taken from an IMET sensor mounted on the bow tower. · Secondary wind speed and direction are taken from the ship's anemometer. Direction is obtained from a synchro output and is resolved to 0.1 degrees. · True wind speed and direction are computed from relative wind speed & direction and ship speed & heading. · Bottom Depth-- Bottom depth is taken from a DataSonics CHIRP II depth sounder. · Sea Surface Salinity-- Sea surface salinity is measured with a Sea Bird Model 21 Thermosalinograph. The water intake is located at the bow at a depth of approximately 8 feet. The seawater is passed through a debubbling chamber before salinity is measured. · Sea Surface Temperature--A SeaBird Model SBE 3 Temperature sensor is mounted at the through-hull fitting for the thermosalinograph. · Fluorometer-- A Turner Designs Model AU10R with a continuous flow cuvette system is connected to the same intake as the sea surface temperature and salinity systems. Both reading and range are monitored by the system. The seawater is passed through a debubbling chamber before fluorescence is measured. · Seawater Flow--Flow through the seawater pumping system is continuously monitored and recorded. · Barometric Pressure-- measured with a Vaisala electronic barometer. The range is 900 to 1050 millibars and is resolved to 0.15 millibars. · Air Temperature -- is taken from an IMET sensor mounted on the bow tower. · Relative Humidity -- is measured with an IMET sensor mounted on the bow tower · Solar Radiation-- Epply PSP, PIR, and TUV solar sensors are mounted on the mast. The analog output from these sensors is digitized within 2 meters of the sensor to eliminate noise. · Precipitation--A Scientific Technology Inc. Model ORG -715 precipitation sensor is mounted on the fly bridge. · Winch Parameters-- Winch in use, wire rate, meters of wire out, and tension are monitored. *_DEPTH SOUNDING EQUIPMENT_ * · DataSonics CHIRP II sonar system is installed. It can operate on either 3.5 or 12 kHz or both frequencies simultaneously. Data output is a 4mm SEGY format tape. · EDO Western Model 323B 12.0 kHz Echo Sounding Transducer-- This transducer is capable of handling a maximum of 2000 watts and has a total beam width of 30 degrees. · Raytheon TR109 Transducer Array-- The array is mounted inside the hull and "shoots" through a fiberglass window. The array consists of 12 transducers. *_WIRE METERING AND BLOCKS_* · One General Oceanics 1.0 meter circumference counter-balanced block grooved for 1/4" diameter wire. · Two General Oceanics 2.0 meter circumference counter-balanced blocks grooved for .322" diameter wire. · One General Oceanics 2.0 meter circumference counter-balanced trawl block grooved for 9/16" or 1/2" wire. · There are three winch readouts, located at the winch controls, in the electronics lab, and outside by the gallows. These readouts display wire rate and meters of wire deployed. Tension is monitored on a strip chart recorder in the electronics lab. These readouts are also connected to the CIDS system. *_ _* *_DOPPLER CURRENT PROFILERS_* · A RD Instruments 38 kHz Phased Array Ocean Surveyor is installed in the hull. · Two in hull mounts for simultaneous use of a 150 kHz and 600 kHz ADCP system. See the section on “Mobile Equipment for Use on RSMAS/HBOI Ships or Other Vessels” for availability of ADCP systems. *_ _* *_ANALYTICAL QUALITY WATER SYSTEM_* A Barnstead 8 liter per hour still is located in the wet lab. The output of the still is held in a 30 liter reservoir. The water can then be used directly or further polished with a four bowl Milli-Q system. Final water quality is > 10 megohm. * *
