It’s been well established by now that the agricultural systems producing our food contribute at least one fifth of global anthropogenic carbon emissions—and up to a third if waste and transportation are factored in. A troubling new report points to a previously overlooked source: an industrial fishing process practiced by dozens of countries around the world, including the United States, China, and the E.U.
The study, published today in the scientific journal Nature, is the first to calculate the carbon cost of bottom trawling, in which fishing fleets drag immense weighted nets along the ocean floor, scraping up fish, shellfish and crustaceans along with significant portions of their habitats.
As they prowl the oceans, sharks aren’t just hunting. Some of them are glowing. And now researchers have identified the largest glow-in-the-dark species with a spine — on land or sea — that has ever been found.
A study published last week in Frontiers in Marine Science established that kitefin sharks — a species that grows to almost six feet in length — emit blue-green light. The scientists who led the monthlong expedition in waters off the coast of New Zealand also expanded the scientific understanding of what makes several species of tiny, deep-swimming lantern sharks glow.
Marty Odlin, who grew up and lives on the Maine coast, remembers what the ocean used to be like. But now, he said, “It’s like a desert and just within my lifetime.” In the last few years, he said, he has seen lots of sea grass and many other species virtually disappear from the shoreline.
Mr. Odlin, 39, comes from a fishing family and has a passion for the history of the ocean and the coast, both of which have informed his sense of the ocean’s decline, a small part of the catastrophic deletion of marine life over the last several hundred years.
Using his training as an engineer, Mr. Odlin has decided to try to reverse that decline with his company, Running Tide, which is based in Portland. Using a combination of robotics, sensors and machine learning, he is building an aquaculture operation that is selling oysters now and eventually clams. He is also using that system to grow kelp, with the goal of producing enough of this seaweed to pull carbon dioxide from the atmosphere and permanently sequester it by burying it on the ocean floor, and sell carbon offsets.
Being the only Black student in a chemical oceanography class during graduate school, Dr. Ashanti Johnson made it her life’s goal to thrive in her chosen field of work and create a support system for other people, especially people of color.
A conversation with a female marine biology student when she was in fifth grade, coupled with watching the works of French naval officer, conservationist and scientist Jacques Cousteau, piqued her interest in oceans.
Hundreds of citizens will fan out across the nation’s capital next week to meet with lawmakers in what’s projected to be the largest ocean lobby effort in US history. On Tuesday and Wednesday, they will meet with Biden administration officials, federal agencies, and members of Congress for a nonpartisan Ocean Climate Action Hill Day. The goal is to promote a number of priorities from the Ocean Climate Action Plan (OCAP), which has been developed by a broad national coalition over the past two years.
