Small Ponds, Big Impacts: CFL Researchers Explore Urban Ponds to Better Understand Human Influence

by Madelyn Anderson – Fieldwork comes in many forms. Some researchers spend their days wading through Wisconsin’s wetlands, looking for bugs in local rivers, and boating through Lake Mendota, the birthplace of limnology in North America.  But other scientists are at work right in your own backyard or neighborhood park.  PhD candidate Jessica Briggs is …

Researchers Identify Five “Phases of Recovery” for a Nutrient Polluted Lake

by Adam Hinterthuer – When it comes to easing a lake’s water quality woes, there’s no such thing as a quick fix. Lakes and reservoirs across the U.S. suffer from problems like excessive algal growth and deep water “dead zones,” both of which are fueled by human development, agriculture and other land use changes sending …

What a Difference a Day Makes: Lake Mendota Goes From Blue-Green to Crystal Clear

by Anna Mueller – I showed up at the Center for Limnology’s Hasler Lab a few hours after the sun had risen and it was already getting hot. I was sweaty from biking to work and could feel the sun burning against my hair. Like any other day, I walked around the squat CFL building …

“Within the first few hours, I already looked at the lake differently.” Hasler Lab’s summer intern reflects on her first week.

by Anna Mueller – I have grown up in the Madison lakes – jumping into Mendota and Wingra every summer without a second thought, doing polar plunges late in the fall, fishing with my brother. And, this year, rowing competitively for the Badgers. When I enrolled for my first semester at UW Madison, I chose …

Fan Mail and A Few Thoughts About Science’s Role in Society

A few weeks ago, a letter arrived in our mailbox here at Hasler Lab from a reader of this blog. It was … not the most positive message. In fact, it stopped just short of “mean Tweet” territory. Here, in its entirety, is the letter:  It seems to me that your blog is no different …

In Rare Dose of Good Climate News Study Finds That, No, Algae Blooms Aren’t Getting Worse Everywhere

As Earth’s average temperature rises, climate change impacts are being felt across the globe. Hurricanes and wildfires are bigger and more destructive. Extreme rain events are more common. Droughts last longer. But, surprisingly, one big problem with a climate connection isn’t getting universally worse. According to a scientific study published online October 5th in Frontiers …

Water We Talking About? Is It Safe to Swim?

Happy Friday! We are 9finally) back with Water We Talking About – a series where kids send us freshwater-related questions and we track down real-life scientists to answer them. This week, brothers Will and Tom sent in a whole bunch of questions. But one, in particular, stood out because, as anyone living near a southern …

Learn Your Lakes: Spring Runoff and Nutrient Loading

This weekend, my family and I went on a drive. These days, any chance to leave the house while still practicing safe social distancing feels like a blessing and this drive felt especially so. There wasn’t a cloud in the sky and hints of the lush, green landscape Wisconsin will soon become were everywhere – …
