Climate Change Threatens Drinking Water Quality Across The Great Lakes

“Do Not Drink/Do Not Boil” is not what anyone wants to hear about their city’s tap water. But the combined effects of climate change and degraded water quality could make such warnings more frequent across the Great Lakes region. A preview occurred on July 31, 2014, when a nasty green slime – properly known as a harmful algal bloom, or HAB – developed in the western basin of Lake Erie. Before long it had overwhelmed the Toledo Water Intake Crib, which provides drinking water to nearly 500,000 people in and around the city. Tests revealed that the algae was producing microcystin, a sometimes deadly liver toxin and suspected carcinogen. Unlike some other toxins, microcystin can’t be rendered harmless by boiling. So the city issued a “Do Not Drink/Do Not Boil” order that set off a three-day crisis.

The Science in Indigenous Water Stories, Indigenous Women’s Connection to Water

Water is life. It is a familiar phrase, frequently spoken today. Even so, little thought goes into what this simple phrase means. We exist in water throughout our lives, dependent on it from conception, surrounded in water in our mother’s womb, until our last water vapor breath. Water is so common, we are so accustomed to our submergence in it that we fail to notice how vital it is and fail to recognize our dependence on it, taking for granted the water vapor-laden environment we exist in every moment of every day…

Data Science in Indian Country

At the end of July 2022, some 150 individuals from across the country gathered at the University of Minnesota Twin Cities for “Data Science in Indian Country,” the Fifth Geoscience Alliance Conference since 2010. Founded by Dr. Nievita Bueno Watts of  California State Polytechnic University, Humboldt (Cal Poly Humboldt), Prof. Anthony Berthelote of Salish Kootenai College, and Dr. Diana Dalbotten of the University of Minnesota’s St. Anthony Falls Laboratory, the Geoscience Alliance (GA) is a coalition of students, educators and staff, Indigenous community members, and others committed to broadening the participation of Native Americans, Alaska Natives, and people of Native Hawai’ian ancestry in the geosciences…

The Summit of STEM: Navigating the Uneven Terrain

Endless hours writing and analyzing samples in the lab was not the most difficult part of graduate school, however. It was walking into a class and seeing that, yet again, no one else looks like me. It was walking into a room and knowing I must fight twice as hard to disprove any underlying biases people might have of me. It was when comments were made that weren’t necessarily targeted at me, but that impacted me because I was the only black woman in the room, lecture hall, or meeting.

Reflections on Negotiating the Science-Society Relationship Together

By The Tropical Rivers Lab. At the Tropical Rivers Lab at Florida International University, rivers have convened us to think deeply about how to best understand them and apply that understanding towards their conservation and sustainable management. We explore different aspects of south Florida ecosystems, Amazonian riverscapes, and East African waters, with collaborations across the tropics. When we decide “how” to best understand rivers, it is not just about the scientific questions we ask, but also about where those questions come from, how we relate to them, and ultimately, how these questions mediate our role with society…
