The Extech BR90 is a palm-sized, waterproof (IP67) 8 mm camera probe with a 77 cm (2.5 ft) flexible goose-neck cable to retain its configured shape. The borescope features a unique compartment to coil the camera probe for easy storage. Its 640 x 480 pixel resolution, 2x digital zoom, and built-in bright LED lamps help project viewed objects clearly on the large 10.9 cm (4.3 in) color LCD display. The monitor has adjustable brightness, 180° image rotation, mirror-flip feature, and video output. It’s a fully loaded inspection camera at an affordable price.

Green Water in Green Bay: Using Data Buoys to Monitor the Southern Bay
While the bay of Green Bay has been referred to as the largest freshwater “estuary” in the world, the watershed hosts intensive agriculture and contributes one-third of Lake Michigan’s total phosphorus load. 
 
 The Fox River flows into the bay, carrying excess nutrients largely the result of non-point source runoff from the watershed. With a history of deterioration extending well into the last century, the bay ecosystem suffered significant declines in water quality. 
 
 This, in turn, stimulated major clean-up and ongoing restoration efforts to improve water quality. Tracking these changes is an important aspect of ecosystem management.

The Tijuana River runs across the US-Mexico boundary, flowing into and throughout southern California, carrying with it nutrients and contaminants throughout the estuary. In recent decades, the flows have been heavily polluted with untreated sewage from the City of Tijuana. 
 
The wastewater enters the greater Tijuana River estuary, impacting coastal communities and disrupting the natural environment. In order to better understand these cross-border flows, researchers out of San Diego University sought to monitor the waterway test the capabilities of in-situ sensors to measure the contaminated water. 
 
Natalie Mladenov and Trent Biggs were two of the researchers involved in the project, deploying a real-time monitoring system in May of 2021.

Despite the bad rap sharks often get in the media, they are incredibly important to marine ecosystems. Still, sharks residing in coastal, high-traffic areas can pose a risk to public safety—as a result, shark tracking and monitoring projects are often conducted in these waters. 
 
Regardless of the bad press, biologists like Gregory Skomal, a Senior Fisheries Scientist with the MA Division of Marine Fisheries, have always been interested in learning more about shark behavior for the sake of informing conservation efforts. 
 
“I was passionate about sharks as a child. I wanted to be a marine biologist, and pursued it through my education and ended up where I am today,” recalls Skomal.
