Record Flooding in the 2030s, and it's Partly Because of the Moon

A new study on high tide flooding predicts that the mid-2030s could be catastrophically wet in U.S. coastal regions — and it could stay that way for an entire decade.

Led by members of the NASA Sea Level Change Team from the University of Hawaii, the study says that high tide flooding could happen more frequently on several U.S. coasts. Flooding at high tide, often called nuisance flooding, already occurs with regularity in many coastal communities as water routinely sloshes into streets, yards and businesses.

Two factors could converge to worsen flooding at high tide, the study says: rising sea levels fueled by climate change — and the moon.

The moon's orbit is due for its regular "wobble." That is entirely natural, NASA says, and it has been recorded as far back as 1728. Half of the moon's 18.6-year cycle creates lower high tides and higher low tides; the other creates higher high tides and even lower low tides.

Nordic invites community to tour fish farm site

Local officials and community members joined Nordic Aquafarms representatives for a site tour of the proposed onshore fish farm at the defunct Samoa pulp mill facility Thursday. The Norway-based seafood company launched the tour series last week in an effort to address community concerns surrounding the project.

Earlier this year, Nordic agreed to pursue an environmental impact report for the project in response to calls for further environmental analysis.

Although the Humboldt County Planning and Building Department had already released a mitigated negative declaration for the project, a coalition of environmental groups argued that the assessment didn’t go far enough, citing concerns of energy use, fish feed, fish waste disposal, water use and transportation impacts.

If all goes according to plan, Naess said the EIR will be out for public review in September.

“Then it goes for a 45-day public comment period and then, of course, we will need to respond to everything,” she said. “Then hopefully we will receive the final approval. Depending on whether or not it’s appealed, the project would go before the Board of Supervisors.”

(PHOTOS) Nordic Aquafarms Execs Lead Tour of the Corroding Remains of the Pulp Mill Property Where They Plan to Build a Big Land-Based Fish Farm

Executives from Nordic Aquafarms were busy this week giving a series of tours out on the Samoa Peninsula, offering politicians, environmentalists, fishermen and others an up-close view of the dilapidated industrial site — home to the corroding remains of the Evergreen Pulp mill — where the company plans to build a large, land-based fish farm.

The draft environmental impact report for the project is still being prepared, so some of the details remain in flux.

Jennifer Kalt, executive director of environmental nonprofit Humboldt Baykeeper, said her organization still has concerns about whether the project can be completed in a way that protects the ecosystems of Humboldt Bay and the nearby Pacific. But after touring the site on Wednesday, she said in a Facebook post that the project would include not only much-needed cleanup but also construction of a modern stormwater system.

“As it stands today, every major rainstorm carries polluted runoff into the bay,” the post reads. “And the way our legal system works, it will stay that way until someone invests in the cleanup. Nordic estimates it will cost $10+ million to demolish and remove everything. Sure, the Harbor District can continue applying for EPA Brownfields grants, but at $250,000 apiece, it would take several lifetimes.”

HSU expands seaweed research farm

Humboldt State University is expanding and diversifying its seaweed research farm in Humboldt Bay to include bull kelp this summer. With the help of HSU students, researchers aim to inform future decisions about commercial aquaculture and conservation efforts.

Researchers will add 0.33 acres to its existing seaweed farm and create a kelp hatchery onshore at the Humboldt State Marine Lab. The farm, called HSU-ProvidenSea, sits in a permitted area just a few hundred yards off the shores of Humboldt Bay. Students will gain practical ocean farming experience, monitor the reproduction and growth of the bull kelp, track factors like water quality and temperature, and evaluate the cost of seeding and production.

After launching California’s first open-water commercial seaweed farm last year, researchers noticed that bull kelp was growing naturally on lines intended for dulse seaweed.

Kelp traps an outsized amount of carbon dioxide and reduces acidification, a byproduct of a rapidly changing atmosphere. Kelp can also be used for human consumption, animal feed, agricultural fertilizer, as sustainable alternatives to single-use plastic, and more.
