|Usually ships in 1-2 weeks|
Measuring less than 15 inches long, the StarFish 452F 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.

The Starfish 990F has an operating range of 35m (115ft) per channel, while the Starfish 452F and the Starfish 450 have an operating range of 100m (328ft) per channel.
Before putting the sonar in the water, let the boat build up speed to 1-2 knots. For best results, keep the boat at a constant speed between 1-4 knots. The slower the boat speed, the deeper the sonar will tow, and the higher the resolution image will be. The recommended maximum towing speed is 8 knots (including water current flowing against the boat).
In addition to the items included with the side scan sonar system, you will need a Microsoft Windows XP/ Vista/ 7 compatible computer/laptop with 1 free USB port. You will also need a DC battery or a suitably protected AC outlet. The sonar comes with several adaptor cables for DC and AC power options.

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.Read More
It’s an open, dirty secret that the ocean is used as the ultimate sewage solution.
Each year trillions of gallons of untreated waste are sent to the ocean due to a widespread lack of sanitation technology or infrastructure that needs updating as cities and populations grow. As the impact of untreated sewage on the ocean becomes clearer, attention to the problem and strategies for dealing with it have not kept up.
“This is a massive problem and it’s been largely ignored,” said Stephanie Wear, senior scientist and strategy advisor for The Nature Conservancy. Wear has turned her attention to raising the alarm about the effects of sewage on coral reefs, which often loses airtime to other pressing issues like climate change and overfishing.Read More
In 2012, for maybe the first time, Lake Superior got scummy.
Visitors to the Apostle Islands National Lakeshore reported algae washing up on shore around the park.
It was a marked shift for the park, made up of a portion of the Lake Superior lakeshore and nearby islands. The water surrounding the park is cold, clear and typically low in nutrients: a combination unlikely to result in algal blooms.
But, in 2012 and again in 2018 after violent storms, major algal blooms—ones observed over multiple days—washed ashore and clogged the beaches with unsightly, scummy algae.
Not the usual suspects
The algal blooms of Lake Superior are not the algal blooms of warmer, more nutrient-rich lakes like Lake Erie.Read More
