Geoethics in the Field: Leading by Example

Geoscience fieldwork is very visible to the public, and can have lasting impacts on the environment, so it is important that geoscientists integrate ethical principles into our field practices — and impart them to our students.

Benchmarks: March 31, 1933: The Civilian Conservation Corps is established

On Jan. 25, 1938, a heavy winter snowstorm struck Wisconsin, blocking the road connecting Blackwell to the nearest hospital 10 kilometers away in Laona. The storm left Blackwell resident Stella Simonis, an expectant mother who was hours away from delivering her child, snowed in with no way to get to the hospital, according to an Associated Press article that ran in several Wisconsin papers the next day.

Grounding Asian jumping worms

To tell the difference between a regular earthworm and an Asian jumping worm, pick it up. An earthworm will likely just lay there, perhaps curling gently around a finger, but a jumping worm will thrash around violently until it jumps out of your grasp. Researchers are looking at how this invasive species is altering soil in Wisconsin, where the worms have been found in growing numbers since 2013.

Geomedia: Books: A witty look at "The Ends of the World"

Our planet has been through some harrowing episodes, particularly in the form of mass extinctions since the advent of multicellular life. How organisms came to perish in these events should interest all conscious, intelligent forms of multicellular life lucky enough to still be alive — you and I included. A great way to satisfy that interest is with “The Ends of the World: Volcanic Apocalypses, Lethal Oceans, and Our Quest to Understand Earth’s Past Mass Extinctions” by Peter Brannen, a well-paced, well-sourced and well-written guide to mass extinctions.

Geomedia: Books: "How the Rock Connects Us" shares copper country geoheritage

There is extensive literature on Michigan’s “Copper Country,” but most existing publications on the subject are either technical reports or anecdotal recountings of exploration, mining and life in the “wilderness.” A recent book, “How the Rock Connects Us: A Geoheritage Guide to Michigan’s Keweenaw Peninsula and Isle Royale” — written by Bill Rose and Erika Vye, both of Michigan Tech University, with Valerie Martin, a longtime Isle Royale interpretive ranger — fills a long-standing need for a readable, user-friendly explanation of how familiar Keweenaw landscapes and recent mining history are related to the area’s underlying geology. It is an eye-opener.

Abiotic amino acid found in subseafloor rocks

In 2000, scientists discovered a new type of deep-sea hydrothermal vent site in the North Atlantic about 20 kilometers west of the Mid-Atlantic Ridge, which they named Lost City. Nearly two decades later, researchers have discovered that an amino acid detected in rocks beneath the site is produced by a geochemical process, rather than a biological one. The find reveals conditions that might have kick-started life on Earth.

Getting there and getting around Florida

For travelers flying in from out of state, Florida has several major airports, including in Miami (MIA), Orlando (MCO) and Tampa (TPA), as well as numerous other options. Orlando is the most central large hub and may be the best option if you’re heading toward the state’s springs, which are concentrated in the north-central part of the state. For traveling to and between sites, a car is the best option.

Travels in Geology: Finding Florida's hidden freshwater gems

Florida is renowned for its beaches and seascapes, but the state also has possibly the highest concentration of springs in the world, due to the karst geology and climate. Whether you are a cave-certified scuba diver, are on the hunt for fossils, or you and your family are just looking for a vacation from Florida’s more crowded beaches and theme parks, Florida’s freshwater offers something for everyone.

How to become a cave diver

While snorkeling the spring pools is cool (no pun intended), a more in-depth way to experience Florida’s freshwater springs is to scuba dive in them. However, entering the caves requires you to get a cave diving certification. That’s because cave diving has inherent challenges distinct from scuba diving’s own challenges. Even after you’re familiar with buoyancy control, breathing control and how to work your gear (all part of getting scuba certified), there’s much to learn about the specifics of cave diving.
