FCC special event station (W4U) celebrating the Alabama Undersea Forest

Calling all ham radio operators: The Federal Communications Commission has authorized special event callsign W4U to operate through Saturday, 11 September 2021. This special event station, the “Gulf of Mexico Underwater Forests,” will educate the worldwide amateur radio community about a unique scientific discovery: remains of an ancient cypress forest that once graced the Alabama coastline but now, due to sea level rise, lies 60 feet beneath the waves.

The site is littered with 60,000-year-old tree trunks encrusted with a huge variety of sea creatures, and shot through with burrows of wood-eating clams known as shipworms. With expert assistance from the Dauphin Island Sea Lab (DISL), a team of researchers from the Ocean Genome Legacy Center at Northeastern University and the College of Pharmacy at the University of Utah are exploring this unique site using a combination of SCUBA and robotic submarines. The project, funded by the National Oceanic and Atmospheric Administration (NOAA), aims to discover new species of animals and drugs—such as antibiotics and anticancer agents, and industrial enzymes, such as cellulases—made by the unique creatures found in this ancient underwater forest.

On Tuesday, 7 September, and Wednesday, 8 September, from 10 AM–4 PM EDT, a ham radio station will be set up at Northeastern’s Marine Science Center. Professor Mark Patterson (WB2OIL), who is a co-principal investigator on this project, along with Ocean Genome Legacy staff and the Marine Science Center community, will be on hand to answer any questions about the underwater forest research. We’ll discuss the remarkable animals living in the Alabama Undersea Forest in the Gulf of Mexico, the importance of marine DNA repositories, and so much more! We hope to make contact with ham radio operators thousands of miles away.

We will dive deep into this unique underwater forest, and ask what it can tell us about both the past and the future. The ancient wood, impeccably preserved after 60 millennia buried under the sea floor, was likely re-exposed recently due to severe storm activity. This site and its creatures may not only reveal drugs of the future, but will also help us to understand the fate of a world ocean in the face of climate change driven sea level rise and increasingly powerful storm activity.

UN Reaches Historic High Seas Agreement

Last weekend, the United Nations reached an agreement on a landmark treaty aimed to protect life in the high seas! This treaty focuses specifically on resources that are contained in ocean areas beyond national jurisdiction. These areas, which are currently largely...

Watch Dan Distel’s Darwin Festival Talk!

Did you know that there is currently a marine ecosystem off the coast of Alabama that is being powered by an ancient undersea forest!? OGL's Dan Distel gave an amazing talk about how this is possible at Salem State's Darwin Festival in February. If you missed it, you...

How our DNA got all marked up

We are all familiar with the genetic code—the simple set of three-letter words that translate the As, Ts, Cs, and Gs of DNA into the diverse and complex forms we know as animal life. But, if every cell in an animal has the same DNA, how does one cell know to become a...

A new paper from OGL solves an old mystery

Shipworms are wormlike wood-eating clams that have been the nemesis of mariners since the first wooden boat set out to sea—and for good reason. Shipworms can gnaw their way through a wooden hull in a matter of months. Since at least 350 BCE, scientists have pondered...
