The ocean is calm on the Sunday in April when surfers and activists gather on Pleasure Point to test the water for radiation.One places a plastic case and a 5-gallon jar on the end of his surfboard, paddles out beyond those waiting to catch a wave, and fills the jar with water.

“We’d like to do three to four samples a year,” says Robin Brune, a resident of Felton. “This is just the first one.”

Brune says her heart grew heavy when she learned about the radiation coming from Japan. “Santa Cruz is so much about surfing and [I wondered] what would it be like, what would our lifestyle, what would our city be like if it was not safe to surf,” she says.

Brune started a MeetUp group called Save Our Surfers Fukushima Response Santa Cruz so people could gather to share information about radiation. The group identified a scientist analyzing samples of seawater for radiation from Fukushima, and Brune arranged to send him some water collected in Santa Cruz.

“There are a lot of people who have more questions than answers, me being one of them,” she says. “But I felt like it was really important to meet each other, and work together and build community around this issue.”

Fukushima in Fish

Wind Euler is with the group MamaBears Against Nukes in Arizona. In April, she spoke to a community group in Santa Cruz County about exposure to low levels of radiation. Eating contaminated fish, Euler says, carries more risk than swimming in lightly contaminated water.

“Maybe eating one fish, might not hurt,” she says. “But if you keep on eating fish and keep on eating fish, you get a chronic internal exposure. And that’s where the danger lies.”

Concerns over contaminated seafood arose about five months after the Fukushima disaster, when bluefin tuna caught off the coast of San Diego contained radioactive cesium released during the accident. Ken Buesseler studies marine radiochemistry at the Woods Hole Oceanographic Institution in Massachusetts. He explains how the US Food and Drug Administration sets safety standards for an acceptable amount of radiation in fish destined for market.

Testing Our Radioactive Coast

Scientists predict that radioactivity from the Fukushima nuclear disaster three years ago could reach the west coast this year. There’s no government monitoring of radioactivity in the ocean, so researchers are teaming up with citizens and groups along the West coast to do sampling.

As the accident at the Fukushima nuclear power plant developed, radioactive water streamed into the Pacific Ocean, where it mixed with the Kuroshio Current, a strong current moving from Japan, into the ocean just south of the major releases.

Ken Buesseler studies marine radioactivity at the Woods Hole Oceanographic Institution in Massachusetts. He’s running a program to measure the amount of radiation from Fukushima that reaches the West Coast. That information helps scientists track how ocean currents transport and dilute the radioactive particles.

How the Drought Looks from the Fields of Salinas Valley

Play

In the Central Valley farmers face significantly reduced supply of water. That’s not the case in the SalinasValley, where farmers continue to draw from wells. Wes Sims reports fields remain in production, though growers are taking steps to conserve.

Cliff Stout, general manager of Classic Salads, demonstrates the harvesting of kale that his company grows in the Salinas Valley. The fresh stalk cracks and snaps in his grip.

“We take our hands around the top few leaves, leaving those behind, and we basically strip the plant of all its leaves, removing kind of the yellow ones or the not so good-looking ones and under…”

Now in its 14th year of operation, Classic Salads, farms 850 acres of specialty salad and vegetable items. All while keeping an eye on drought conditions throughout California.

“So we’re very thankful for these wells and not depending necessarily on surface water to take care of our crops.”

Sediment Necessitates & Complicates San Clemente Dam Removal

Play

There are two big dams on the Carmel River. One of them, the San Clemente, is about to be demolished to restore fish habitat. But with a reservoir full of sediment behind it, that’s a delicate process. KUSP’s Wes Sims reports.

With the threat of winter storms mostly faded, California American Water is continuing its $83 million project to remove the San Clemente Dam and restore the river to its original state. The work, located 18-miles up the Carmel River from the Pacific Ocean, involves capturing 2.5 million yards of mud and rerouting the river.

When Your Garden Needs Help, Give it Some Tea

Play

There’s a store in Santa Cruz that sells everything you might want to make your own compost or even convert your compost into soil additive to inoculate your plants with beneficial microorganisms. KUSP’s J.D. Hillard has this report

55 gallon barrels of compost tea - bubble behind 'Soil Solutions', James Neve.

55 gallon barrels of compost tea bubble behind ‘Soil Solutions’, James Neve.

In the parking lot of Soil Solutions, there are the bags of prepared compost and soil you might find at any garden store. But the store in Santa Cruz’s Harvey West neighborhood isn’t a typical garden store. Owner James Neve advocates a whole new approach to gardening.

Helping You Raise Good Microbes

“What we offer is a non synthetic, a non-chemical way of feeding your soil,” Neve says.

When he says “feeding your soil,” he means he doesn’t sell chemical fertilizers or pesticides. Instead everything he sells is intended to cultivate the biology of your soil so it’s more nutritious for your plants.

Showing Otters Love Through Your Taxes

More than two million dollars have been contributed to the California Sea Otter Fund through donations on the state income tax form. The fund has become an important source of support for sea otter research and conservation programs in the state. But the program will only continue if donations reach a mandated minimum target this year, which is the largest in its seven-year history.

The serenity of Loch Lomond, near Lompico, belies the critical nature of drought conditions affecting the backup water supply for the City of Santa Cruz.  This man-made reservoir was created a half century ago with the construction of a dam across Newell Creek.

Yes, the Levels are Low
On our recent trip to the Loch Lomond, we were shown the water level indicators: a series of staff-plates with five hard-wood measuring sticks descending the shore line.  All five are bone-dry, indicating current surface water elevation at just over 550 feet, which is very low according to Chris Berry who is the Santa Cruz Watershed Compliance Manager.

Recharging Wells With Purified Wastewater

By Wes Sims | KUSP News

In addition to the Carmel River, the Monterey Peninsula gets 30 percent of its water from wells drawing from an enormous layer of rock beneath Seaside and Marina. The Seaside Aquifer can’t provide enough water to replace the Carmel River. This is why CalAm has proposed to build a desalination plant. It may be possible, though, to add more water to the Seaside Aquifer.

Groundwater recharge is the process of replenishing natural underground freshwater aquifers to provide a continuous supply of drinking water, as described by Andy Fisher; a professor of hydrology at U.C. Santa Cruz.

By Melissae Fellet | KUSP News

A group of otters has traded life in a kelp forest for a home in Elkhorn Slough. Although otters have historically lived in estuaries, this is the first opportunity that scientists have had to learn about the details of their daily lives in estuaries. The observations will give them a preview of what might happen as otters expand their range and move into other estuaries.
