The 990F is the ultimate high resolution StarFish side scan sonar for extreme image definition and target detection. Based on the popular and proven 450F design, the StarFish 990F uses high frequency 1MHz acoustic chirped pulses with a 0.3 degree horizontal beam width to produce the most defined and clear images from any StarFish system. With a 35m range capability on each channel (giving 70m total swathe coverage), the StarFish 990F is the ideal tool for high resolution surveys in ports & harbors, academic research, inland waterways such as rivers and canals, and SAR (Search And Recovery/Rescue) operations.

Measuring less than 15 inches long, the StarFish 990F sonar is the smallest towed side scan sonar available. The system is independent of the boat, requiring no fixed installation and making it easy to transport and operate from any vessel. The topside controller connects to any Windows PC or laptop via USB connection for easy operation by a single person. Simply deploy the sonar by hand and tow from your boat to capture and record real-time images of the seafloor below.

UNC Wilmington Uses Advanced Gear To Prepare Students For Oceanography Work

College professors know that preparing students to be good oceanographers takes a lot of hard work. Getting all the basics down, like the necessary math, chemistry and biology skills, among others, can be difficult on its own. But the real trick comes when all those skills are combined and used to approach actual work in the field. And when students finally get out of the classroom, there’s still more prep, like training them to use the advanced research tools that scientists use nowadays. Still, college oceanography programs today get the job done by working in applied learning components that have students sailing on research vessels or suiting up in scuba gear to get hands-on experience.

Pulse Flow Brings Colorado River Delta Big Benefits

A few years ago, a pulse flow was released into the Colorado River Delta per Minute 319 of the U.S.-Mexico Water Treaty of 1944. The flow began March 23, 2014 and ended on May 18, 2014, pushing around 130 million cubic meters of water downstream. A few months after that, this magazine checked in with some of the scientists involved in monitoring the effects of the pulse flow. Investigators told us they had deployed more than 100 piezometers to study groundwater levels. Flow trackers were giving them discharge data and measurements on salinity were being gathered with conductivity probes. For gauging the impacts to waterfowl, the researchers were using stereos to send out mating calls while listening for responses. But there was so much more data collection underway than we knew.

Lake Erie Infographic

It’s pretty easy to find a Lake Erie infographic these days. And that makes sense, because the water body is an incredibly important one. We laid out some of the dynamics that make it that way in our most recent print edition, published in fall 2016 . Those include its shallow depth, a factor that makes it one of the most productive Great Lakes both for fish and algae. Another is the population surrounding Lake Erie. Did you know that the Erie watershed has nearly 12 million people? That makes it the most populated area of the region! In our latest edition, the Lake Erie infographic serves as a nice background for readers who may be unfamiliar with the lake. It also helps to introduce our coverage of Lake Erie’s western basin.
