Muddy Water Has Town Official Singing the Blues
Coastwatch GLERL NOAA imagery December 17, 2021 (annotated). Several years ago, when our kids were young and at least one was still in elementary school, I visited a class of 3rd graders taught by a friend of the family’s and put on a soil erosion demonstration. The “show and tell” consisted of setting up rainfall simulators for two contrasting land cover types represented by two baking pans: one filled with …

Nevada Earthquake Raises More Doubts about Yucca Mountain
On Friday, May 15, 2020, a magnitude 6.5 earthquake rocked Nevada and portions of California. With the epicenter located about 22 miles west of Tonopah, NV, no serious damage was recorded aside from cracked highway pavement in the mostly remote surroundings, far from population centers. Reportedly, Nevada has not seen an earthquake of this size since 1954. Worth noting, the earthquake epicenter is about 100 miles away from the Yucca …

Chemical Cocktails Confound Phosphorus Management
It’s been fifty years since the Canadian government at the urging of the International Joint Commission set aside the Experimental Lakes Area near Kenora, Ontario in 1968 to conduct large-scale experiments in aquatic ecology. There, the young Director named David W. Schindler, who would go on to become a world-renown limnologist, and others conducted experiments with nutrient loading and produce one of the most iconic photos in the field of …

Great Lakes Restoration Initiative Ag Programs Under Review
The Great Lakes Commission (GLC) has received a two-year $750,000 grant to evaluate the effectiveness of money spent on farm conservation programs by the Great Lakes Restoration Initiative (GLRI). In addition to the GLC, Ohio State University and Michigan State University will play a role in the evaluation process. Earlier this year, the Trump Administration proposed to end funding for the Great Lakes Restoration Initiative and National Sea Grant programs. …

Wetlands and Flood Mitigation: The 10 Percent Solution
Following the Great Flood of 1993, an official report called for more research to find ways to prevent flood devastation, apparently unaware the problem had been mostly solved, conceptually over a decade earlier. But taking action through the implementation of a national wetland restoration program has faced intractable political and economic obstacles.

Keep Your Shirt On, Save Some Coral?
This is not great news, especially for those of us who like to be out in the sun but get really bad sunburns. As reported by Nature and Scientific American, Hawaii state senator Will Espero has introduced a bill to ban sunscreens containing oxybenzone and octinoxate, two chemicals that may pose risks to us, such as endocrine disruption, as well as to coral. The Environmental Working Group maintains lists of …

Maine Shake Map Using Surficial Geology and Crowd-Source Responses
Researchers in Maine (Marvinney and Glover 2015) have created a clever earthquake risk shake map using readily available surficial geology maps and online responses from state residents. Did you feel it? That is the name of a USGS Earthquake Hazards Program interactive website that “collects information from people who felt an earthquake and creates maps that show what people experienced and the extent of damage.” I first became interested in …

Lake Erie Algae Blooms Correlate to June Rainfall
June precipitation appears to be positively correlated to algae blooms in Lake Erie. Looking at monthly precipitation data readily-available from Weather Underground and comparing it to the Western Lake Erie Algae Bloom Severity Index, I was surprised by the strength of the correlation (0.6, 0.85 with an “outlier” removed). June precipitation was the only month to correlate to the Severity Index in my data set and I was surprised that …

Half of U.S. Corn Crop Now Goes to Ethanol
Farming has always been about energy. We eat food for energy our bodies need to survive. But now American farming is increasingly about filling gas tanks as well as bellies. At a typical gas station found along an interstate highway, one can fill up on gasoline blended with 10% ethanol made from corn, pay for it using a plastic card, perhaps made from corn, pull around the side of the …

Herbicides, Critical Source Areas, and Vegetated Buffers
Waging Chemical Warfare on Weeds Last fall, while on one of my country road walking routes, I noticed an advanced infestation of marestail (Conyza canadensis) in a soybean field. Evidently, this weed, and others, is becoming herbicide-resistant. A new agricultural herbicide called Acuron (link goes to manufacturer’s website) is on the market, and in some fields. Acuron has been developed in response to “superweeds” that have grown resistant to glyphosate, …
