The Extech VB300 can measure and record shock and vibration (acceleration) readings over its +/-18g measurement range. This device will record 3-axis g-force and related peaks to provide a history of shock and vibration conditions. The real time clock provides time stamps for all data.

The user can easily configure the logging rate, high/low alarm and start-mode, and download the stored data by plugging the VB300 into a PC's USB port and running the supplied PC software. Measurement data can be plotted, printed and exported for use with other applications such as word processors and spreadsheets. The data logger is supplied with a long-life 1000 hour lithium battery.

The VB300 memory uses a 4MB Flash device that can hold 85,764 peak acceleration samples and 210 freefall samples. Additional features include:

  • Selectable X-, Y-, Z-axis or any combination (via software)
  • Selectable data sampling rate: 50ms to 24 hours
  • Datalogs 85,764 peak acceleration samples
  • Manual and Programmable start modes

ROV Yogi Gets Underway In Yellowstone Lake

Earlier this year, we covered a work in progress to build a new remotely operated vehicle (ROV) for Yellowstone Lake . It was just an idea back then, but the exploratory craft has since become a reality thanks to some determined researchers and a Kickstarter campaign that reached a goal of $100,000 in funding. Full cost for building the vessel was around $500,000, but crowdfunding a portion of it allowed officials at the Global Foundation for Ocean Exploration (GFOE), a nonprofit engineering group, to spur public interest. In a similar vein, they named the completed ROV “Yogi” in honor of the famous fictional comic book character devised by Hanna-Barbera who gets into trouble at Yellowstone National Park.

Elliott Bay Reconstruction Benefits From Chum Salmon Finds

Like many commercial waterfronts, Seattle’s Elliott Bay has been built to withstand the natural forces of erosion. This has come with the addition of structures like concrete seawalls and piles of riprap, most of which were put in place in the 1930s. But there are a few manmade beaches that have sprung up in recent years along its banks. Some of these have come about because the city is reworking the shoreline following an earthquake that occurred around 10 years ago. And moving forward, Bay planners are looking to add still more improvements, including complexities in seawalls, underwater benches in the intertidal zone and a new beach, all of which are meant to help support fish habitat.

Boise River Watershed Watch Shows Volunteers River Issues

Having just wrapped up its ninth year, the Boise River Watershed Watch program is an increasingly popular citizen science program in Boise, Idaho. It takes interested volunteers and joins them with expert scientists from the U.S. Geological Survey (USGS) who teach them about the river’s health and sampling water quality using transparency tubes, dip nets and chemical test kits. “Our focus is to educate folks on the parameters that we measure, to give them an idea of the river’s health,” said Tim Merrick, public information officer at the USGS’ Idaho Water Science Center. “So they can collect data on the river’s conditions and get plugged in.
