The Extech 600A True RMS AC/DC Clamp Meter measures temperature, true RMS, capacitance, and current. The AC/DC current is to 600A and the temperature probe measures from -58 to 482°F.  The data hold function freezes the measurements for analysis on the large 4000 count LCD display. An audible beeper will alert users if continuity is present.

Targeting Spawning Bass: Are They Going to Bite?

This time of year, anglers all over are fishing for bass they can see in the shallows. Some bass will be easy to catch and some are nearly impossible, like those that are in the act of spawning instead of just guarding their beds. There are a few things that I do to determine if the fish is going to bite and if they are worth spending time fishing for. Locating Bedding Bass One of the best ways to find bedding bass is to cruise the shallows with your trolling motor at about 40 or 50%. I have found that this is the best speed to both cover water and avoid spooking fish. Anything faster will scare fish away long before you get to them.

Researchers Find Link Between Climate Change and Gastrointestinal Illnesses

An understanding of climate change’s effects on the environment has become commonplace and grows every day, but one researcher from Florida State University is looking to answer a new question: What are climate change’s effects on people’s health? In one of the first studies of its kind, Chris Uejio, an assistant professor at FSU, and a team of researchers studied how climate change can affect the roughly 20 million Americans (according to the Environmental Protection Agency) who consume untreated drinking water on a daily basis. Because climate forecasts are predicting higher rainfall rates over the next few decades, coming down in intense storms, Uejio said those flashes could cause flare-ups in waterborne illnesses.

Data Buoys Infographic

We put together this infographic on data buoys for our Spring 2017 edition of the Environmental Monitor ( PDF available online ). Organizations across the globe use data buoy systems to observe and monitor atmospheric and oceanographic conditions in remote locations. Measurements range from air pressure, humidity, wind speed and direction to wave height, water temperature, dissolved oxygen and other water quality parameters. With the help of national and international networks, reliable and comprehensive data sets are made available for research and public safety.
