  • About the Edition

    This report documents the work performed by the Woods Hole Oceanographic Institution (WHOI) and the Battelle Memorial Institute from August 1988 to December 1992 in the NSF sponsored development of an Integrated Seawater Sampler and Data Acquisition Prototype. After a 6-month initial design study, a prototype underwater profiing unit was designed and constructed, containing the water acquisition subsystem, CTD and altimeter, control circuitry and batteries. A standard WHOI CTD was adapted for use in the underwater unit and was interfaced to the underwater controller which had a telemetry module connecting t with a deck control unit. This enabled CTD data to be logged in normal fashion on shipboard while additional commands and diagnostics were sent over the telemetry link to command the underwater unit"s water sampling process and receive diagnostic information on system performance. The water sampling subsystem consisted of 36 trays, each containing a plastic sample bag, the pump and control circuitry. The sample bags, initially sealed in a chemically clean environment, were opened by pumping the water out of the tray, thus forcing water into the bag by ambient pressure. The command system could select any bag, and control the water sampling procss from the surface with diagnostic information on system altitude, depth, orientation and cable tension displayed in real time for operator information. At sea tests confirmed the operation of the electrical and control system. Problems were encountered with the bags and seals which were partially solved by further post cruise efforts. However, the bag closing mechanism requires further development, and numerous small system improvements identified during the cruises need to be implemented to produce an operational water sampler. Finally, initial design tor a water sampler handling and storage unit and water extraction system were developed but not implemented. The detailed discussion of the prototype water sampler design, testing and evaluation, and new bag testing result are presented.

    to investigate the design and testing of a symbiotic system to harvest uranium from seawater. As defined in the proposal, the goals for the project are: 1. Address the design of machines for seawater uranium mining. 2. Develop design rules for a uranium harvesting system that would be integrated into an offshore wind power tower. 3. The knowledge of seawater properties is important in the development and design of desalination systems. Literature contain many data for the properties of sea-water, but only a few sources provide full coverage for all of these properties [1–5]. The data are mainly based on experimental measurements carried out in and before.

This report documents the work performed by the Woods Hole oceanographic Institution (WHOI) and the Battelle Memorial Institute from August to December in the NSF sponsored development of. The integrated multiport sampling valve (MSV) is custom-made and uses a modular design to improve the reliability of the sampling system.

The MSV is one of the most vital components of the serial sampler, as it insulates the sampling cylinders against outside high-pressure seawater during deployment and keeps fluid samples at near in-situ Author: Shuo Wang, Shijun Wu, Mengran Du, Canjun Yang, Xun Wang.

These infosnaps capture four simultaneous video sources, vehicle data, instrument data, and event data as entered by scientists.

The infosnaps are automatically cataloged and immediately accessible and searchable via a web-browser. We developed, built, and deployed the Jason II Virtual Control Van system on seven Jason cruises. Data acquisition system is also installed to the experimental apparatus.

Temperatures are measured by using J-type thermocouples with uncertainly equal to ° number of thermocouple is 20, which are four thermocouples placed in the evaporator, four in the condenser, four in the heat exchanger and the rests in pipe and water containers.

Balkan-Data Acquisition 15 Sampling Rate One of the most critical factors when selecting an A/D board is sampling rate (speed). The sampling rate is a measure of how rapidly the A/D board can scan the input channel and identify the discrete value of the signal present with respect to a reference signal.

On this prototype, the upper structure hosts a renewable energy charging system consisting of solar photovoltaic modules and other ancillaries, including a Supervisory Control and Data Acquisition (SCADA) system.

The FLASC prototype has been deployed in Dockyard Creek in Malta's Grand Harbour, where it will be operated in order to monitor and. concerning the data acquisition system’s multiplexing and signal conditioning circuits, and analog-to-digital converters.

These three functions establish the overall accuracy, reso-lution, speed, and sensitivity of data acquisi-tion systems and determine how well the systems perform.

Data acquisition systems. Seafloor observatories enable continuous power supply and real-time bidirectional data transmission, which marks a new way for marine environment monitoring.

As in situ observation produces massive data in a constant way, the research involved with data acquisition, data transmission, data analysis, and user-oriented data application is vital to the close-loop operations of seafloor observatories.

The natural progression from the sale of seawater was for OSIL to sell associated instruments such as salinometers, sound velocity sensors and CTDs. OSIL provide individually tailored integrated real-time data systems for environmental monitoring and MetOcean data acquisition which deliver reliable turnkey end to end data with multiple.
