Running Tide is facing scientist departures and growing concerns over seaweed sinking for carbon removal

Running Tide, an aquaculture company based in Portland, Maine, has said it expected to set tens of thousands of tiny floating kelp farms adrift in the North Atlantic between this summer and next. The hope is that the fast-growing macroalgae will eventually sink to the ocean floor, storing away thousands of tons of carbon dioxide in the process.

The company has raised millions in venture funding and gained widespread media attention, and it counts big names like the Chan Zuckerberg Initiative among its customers. But Running Tide struggled to grow kelp along rope lines in the open ocean during initial attempts last year and has lost a string of scientists in recent months, sources with knowledge of the matter tell MIT Technology Review.

At least several of the departures were due, in part, to concerns that the company’s executives weren’t paying sufficient attention to the potential ecological effects of its plans. Some employees were also disturbed that Running Tide was discussing more controversial practices, including adding nutrients to the ocean to stimulate macroalgae growth. Read the full story.

The big story

How the world’s biggest gun helped solve a long-standing space mystery

November 2019

On a sweltering day in August, in a windowless strip mall office in Florida, Rafael Carrasquilla and a dozen other students wore surgical gloves as they picked through piles of dust with tweezers. They were hunting for tiny slivers of carbon fiber only millimeters long, almost invisible to the naked eye.

When they found one, they logged its appearance in a database, bagged it, tagged it, and placed it among tens of thousands of others painstakingly organized in ranks of plastic bins.

Carrasquilla leads the fragment characterization effort for the University of Florida, part of a NASA-led experiment called DebriSat that began in 2011. DebriSat was created to answer a question: What happens when a piece of orbital debris slams into a satellite at thousands of miles per hour? Read the full story.
