Details

The SDL V2 Submersible Data Logger is a rugged, self-powered remote data logging system for deploying environmental sensors in lakes, streams, rivers, wetlands, coastal waters, sewers, and culverts without fear of accidental flooding. The system is configured with three sensor ports for connection to industry-standard digital interfaces including RS-485 and SDI-12. Additional sensor inputs are available through the use of adapters. Each sensor port offers a UW receptacle with double O-ring seal for a reliable waterproof connection. Unlike many data loggers, the SDL V2 is truly submersible. The housing and battery compartment are completely sealed and waterproof.

When it comes to field ruggedness, the NexSens SDL V2 is in a class of its own. The housing is constructed of impact-resistant PVC and includes two elastomer bumpers for long-term deployment in close-fitting pipes and buoy ports. Internal circuit boards and communication modules are shock mounted and all access ports incorporate redundant sealing. The SDL V2 withstands extreme wave action, drops, floods, periodic & long-term deployment underwater, and more. When fitted for wireless remote communication, the radio, cellular, and satellite antennas are also waterproof.

The SDL V2 can be powered autonomously by sixteen D-cell alkaline batteries. Optional solar power kits provide long-term continuous operation and solar charging. Common sensor connections include multi-parameter sondes, water quality sensors, temperature strings, Doppler velocity meters, water level sensors, and weather stations. Optional integrated cellular or satellite telemetry modules offer real-time remote communications via the WQData LIVE web datacenter. There, data is presented on a fully-featured and easy-to-use dashboard. Other features include automated reports, alarms, push notifications and much more.

Sunscreen Chemicals in Water Can Harm Zebrafish Embryo Development

If you've ever sat at the beach or on the shore of a lake reapplying your sunscreen and wondered what happens to that sunscreen as it washes off in the water, you're in good company. A team of researchers has been investigating how sunscreen chemicals affect marine wildlife, and their recent paper indicates that ultraviolet (UV) filters from sunscreen and other personal care products can affect zebrafish embryo development. UV filters in the water Dr. Adela Jing Li's group at Hong Kong Baptist University has been studying UV filters for several years.

Low Tech, High Tech and Outdoor Exploration: Butler County Stormwater Monitoring Runs The Gamut For Summer Intern

For ten weeks, from mid-June to mid-August of this year, University of Dayton Environmental Biology major/English minor Tessa Farthing learned how to go out in the field and assess the health of stormwater inlets and outfalls in various places in Butler County, a 470 square mile area between the cities of Dayton and Cincinnati in southwestern Ohio. Not only was she trained in how to find inlet and outfall areas, which was sometimes challenging in and of itself, she was also trained to use some very sophisticated equipment. For some of the tasks she needed to do, however, it was the not-so-technical equipment that ruled the day. In addition to everything else, Farthing says, she was trained how to use her nose.

Sustainable, Sponge-like Material Takes the Color Out of Dyes

Dyes are part of manufacturing everything from clothing to food all over the world. In fact, every year about 700,000 metric tons of dye change the hue of consumer goods. However, about ten percent of that dye ends up in the world's waterways, sometimes with toxic results. Even non-toxic dyes pose a threat in the environment, because changing the color of the water in streams, lakes, holding ponds, and rivers can mean interfering with plants' ability to photosynthesize. This, in turn, disrupts the rest of the local ecosystem.
