SANTA BARBARA, Calif. (KEYT) – A UC Santa Barbara researcher published a paper detailing the intricate impact that kelp forests along local beaches have on the surrounding environment even while dead and dying.

Dr. Kyle Emery with UC Santa Barbara's Marine Science Institute led a team of researchers in surveying 24 local beaches in Santa Barbara and Ventura counties over three separate periods and analyzed the impact of one particular marine plant on the biodiversity found at each beach.

The result of his analysis, Food web structure and ecosystem multifunctionality in a subsidized coastal ecosystem was published in Nature Scientific Reports late last year.

Research that helped in the development of the study was also conducted by the Marine Science Institute's Jenifer E. Dugan, David M. Hubbard, Jessica R. Madden, and Robert J. Miller as well as J. Carter Ohlmann with UC Santa Barbara's Earth Research Institute.

While we might see beaches as a borderline between our terrestrial home and the open ocean, this dynamic environment is home to a crucial life form that has a substantial impact on the both regions, kelp.

Don't call it a plant! Kelp is a term that refers to around 30 species of marine algae. They tend to grow in large, dense groupings we call a kelp forest.

The marine forests are home to an exceptional number of plant and animal species and are a crucial part of federally protected waters locally including the Monterey Bay National Marine Sanctuary, the Channel Islands National Marine Sanctuary, and the Chumash Heritage National Marine Sanctuary.

A common type you might see along California beaches is Macrocystis pyrifera or Giant Kelp.

Trump’s gambit to move ships through the Strait of Hormuz tests the fragile ceasefire

(CNN) — President Donald Trump’s initiative to guide ships through the Strait of Hormuz was a high-stakes, high-risk attempt to jolt loose a resolution to the standoff that had come to define his war against Iran.

But the gambit has put the US’ fragile ceasefire with Iran under strain, as US and Iranian forces traded fire in the contested waterway. Now, no one is entirely sure whether the tenuous peace can hold long enough for halting negotiations to yield some resolution.

“It is very bad and messy at the moment,” a regional source told CNN.

With little sign Tehran would blink in its efforts to block traffic through the waterway, Trump had grown frustrated at the deadlock in the strait. High gas prices and a looming visit to China both created pressure to find a way to get vessels moving.

So from his golf course in Florida on Sunday, Trump announced a plan for the US to help guide certain ships through the strait, dubbed “Project Freedom.” The risks soon became apparent. Booms reverberated in Dubai as Iranian missiles were intercepted for the first time since a truce went into effect nearly a month ago. The US military destroyed six Iranian small boats, US Central Command said. (A report by an Iranian state media outlet disputed that the boats had been sunk.)

The open-ended ceasefire appeared to be stretching to its limit, without clear evidence a negotiated settlement may be near. Speaking to CNN on Sunday, Trump’s foreign envoy Steve Witkoff would only say of talks with Iran: “We’re in conversation.”

Some of Trump’s allies have encouraged him to resume the bombing campaign inside Iran, arguing the US has already weakened the regime and insisting the time was ripe to further degrade its military capabilities.

“I hope this conflict can end diplomatically, but it is now time to regain freedom of navigation and forcefully respond to Iran if they insist on terrorizing the world,” GOP Sen. Lindsey Graham wrote on X this weekend.

Israeli Prime Minister Benjamin Netanyahu, who Israeli sources say is planning a trip to Washington to visit Trump in the near future, convened security meetings Monday. Officials signaled in Israeli media afterward that the country was prepared to resume a bombing campaign.

Despite the hostilities, it was not clear whether Trump had the appetite to resume full-scale bombing inside Iran. He shrugged off a damaged South Korean ship as from an “unrelated Nation” and claimed otherwise there had been “no damage going through the Strait.” He similarly told ABC News of Iran’s drone and missile attacks, “One got through. Not huge damage.”

But he also warned in a phone interview with Fox News that Iran would be “blown off the face of the Earth” if it targets US ships.

“I wouldn’t go into details of whether the ceasefire is over or not,” Adm. Bradley Cooper, head of US Central Command, told reporters Monday. “I think the key thing is, for us, is we’re merely there as a defensive force and to give a very thick layer of defense to comme
