After hours in a boat, do you ever wish that water quality monitoring and data collection could just take care of itself? This wish might be fulfilled with a new monitoring system that YSI will introduce later this year.Knight Rider – that is powerful enough to take it wherever it needs to go. And you don’t even have to leave shore!

Dynamic Duo: Mapping Water Quality

YSI’s reliable and robust 6600 V2 sonde is getting a partner – think K.I.T.T. from ’80s TV show

Through a partnership with OceanServer Technology, the 6600 V2 sonde has been integrated into an AUV (autonomous underwater vehicle) and together the system can map the water quality of entire areas, such as reservoirs and bays, with very high resolution and minimal effort. Several features that make this man-deployable vehicle unique include the intuitive mission-planning software, 10-hour run times with remote RF communication, and a complete on-board water quality sensor suite that samples at a frequency of 1Hz.

The result is detailed maps of water quality parameters at a fine spatial resolution. Water quality monitoring programs can use the vehicle (and only one technician’s time) to sample difficult-to-reach or shallow areas, expand monitoring frequency and resolution, and fill in the gaps of fixed-point monitoring programs. Local and federal agencies will find the vehicle well-suited for rapid response applications, sensitive locations, as well as low-oxygen zones or algal blooms.

Several field demonstrations of the vehicle are underway in the United States. A limited number of vehicles will be available for purchase this summer with a global launch planned for late this year.

CHINA BUYS SIDE SCAN SONAR

 China’s state owned Guangdong Construction Engineering Group (GCEG) has purchased JW Fishers side scan sonar system. The sonar is being used to the map the bottom of various waterways before and after construction projects. It is providing engineers with information on the make up of the bottom (mud, sand, rock, etc.), as well as helping to locate and identify debris or any obstructions.

    GCEG was founded in 1953 and is the largest corporation in the province in terms of size and scale of construction projects. It consists of 38 subsidiary companies that are spread throughout China and abroad with 39,000 employees and 11.5 billion yuan in assets. The group is responsible for number of high-profile, award winning projects such as the Guangdong International Hotel, Guangzhou Haiyin Bridge, Shantou International Finance Hotel, Guangzhou City Mansion, and the China-Guangdong Olympic Stadium. The company has also played a key role in water conservation and hydroelectric projects including the Feilaixia Structure Project and the Dongjiang-Shenzhen Water Supply Project. They have a First Grade Certification for general contracting, construction, water conservancy, municipal engineering, industrial and hydropower equipment installation, and real estate development. In recent years GCEG has also become more involved in large scale engineering projects with the construction of highways, bridges, subways, and airports throughout China, Hong Kong, Macao, and other countries.

    Using Fishers side scan sonar and SONAR VIEW software, GCEG engineers are able to produce detailed maps of the bottoms of rivers, lakes, and the ocean. The sonar images can be displayed on a standard laptop computer or Fishers Splashproof PC with ultrabright LCD display. The SONAR VIEW software offers a wide array features including a variety of color schemes to display images, capturing of screen shots for emailing, zoom capability and a sizing tool. The sizing tool lets the sonar operator quickly determine the length, width, and height of any object. Connecting a GPS allows position coordinates to be displayed and saved with the sonar data. Clicking the mouse on any target automatically shows its position coordinates. Stored data can be replayed at any time and the sonar images edited. The complete system is powered by a 12 volt battery, making it highly portable and easy to deploy from a small boat.
