Blue Frontier

Blue Frontier Blue Frontier builds the solution-oriented citizen engagement needed to protect our ocean, coasts and the communities, both human and wild that depend on them.

Blue Frontier Campaign was founded in 2003 by David Helvarg, author and activist. It works to support seaweed (marine grassroots) efforts at the local, regional and national level, with an emphasis on bottom up organizing to bring the voice of citizen-activists into national decision-making that will impact our public seas. There are now over 2,000 blue groups working on ocean and coastal conserva

tion but largely operating in isolation, and with little coordinated effort among them. Blue Frontier’s mission is to strengthen this ocean constituency through building unity, providing tools, and enhancing public awareness of both the challenges and solutions being offered by these groups to the various threats facing our living oceans.

Why is Seaweed taking over? 🌿⁠
⁠
Our director, David Helvarg, reports in Sierra Club Magazine that massive amounts of Sargassum are washing up on beaches, creating challenges for coastal communities while also providing vital habitat for marine life.⁠
⁠
So what’s behind the seaweed boom, and what can it tell us about our changing oceans? Head on over to bluefront.org to find out more!

El Niño can reshape weather patterns around the world. 🌎🌊⁠
⁠
The deadly European heat wave this Summer and record shattering ocean temperature levels on Saturday both show: it is here, and the worst effects may have yet to come.⁠
⁠
In some regions, it can bring stronger storms, heavier rainfall, flooding, landslides and coastal erosion. In others, it can contribute to drought and increased wildfire risk.⁠

16 Years ago Blue Frontier's Margo Pellegrino paddled an outrigger from Seattle to San Diego to raise awareness of ocean conservation efforts. Now Cat Breed is swimming the length of California to do the same. If they can do that you can vote the Ocean in Nov.

🌊 What happens when water pollution gets out of control?⁠
⁠
On the latest Rising Tide episode, we reconnect with renowned marine ecologist Dr. Nancy Rabalais, who has spent decades tracking the Gulf of Mexico’s massive seasonal Dead Zone.⁠
⁠
Driven by nutrient pollution and algae blooms fueled by agricultural and urban runoff flowing down the Mississippi River, the Dead Zone is a powerful reminder that what happens on land can have major consequences for our ocean. Nancy also discusses the lasting impacts of the 2010 BP oil spill and other changes happening in our marine environment.⁠

Is floating nuclear energy coming to our oceans? ☢️⁠
⁠
Our latest Blue News segment delves into the latest offshore energy and shipping option that is being entertained by our President - one that has been largely flying under the radar.⁠
⁠
Is putting nuclear power plants in our waters and reactors in our shipping vessels the answer to decreasing oil dependency? Or does it pose more of a risk to our future than it's worth?⁠

Kelp forests are disappearing, but the urchins that helped create these graveyards aren’t disappearing with them. 🌊⁠
⁠
New research in Nature Journal reveals how purple sea urchins can adapt to life with very little food, shifting their metabolism into survival mode and conserving energy when kelp is scarce.⁠
⁠
That resilience may create a major challenge for kelp recovery: even after kelp disappears, urchins can survive and continue grazing, making it harder for new kelp forests to take hold.⁠
⁠
Understanding how urchins survive could help scientists develop smarter, more effective strategies for restoring California’s iconic kelp forests. 🌿⁠

With midterms rapidly approaching, remember that the ocean needs our voices, our action, and our votes 🗳️⁠
⁠
From protecting ocean habitats and supporting sustainable fisheries to keeping our waters clean, fighting climate change, honoring Indigenous knowledge, and building a thriving blue economy, the choices we make in the next few months will shape the futures of our ocean and our planet as a whole.⁠
⁠
So, make your voice heard, and make it count for a healthy, resilient ocean this November!

During the first 300 miles of her 900-mile swim down the California coast, Catherine Breed noticed something troubling: there's almost no kelp left.⁠
⁠
Now she's diving into David Helvarg's new book, Forest of the Sea: The Remarkable Life and Imperiled Future of Kelp - trying to understand this loss of normally lush kelp canopy along our coast . ⁠
⁠
Kelp forests are some of the most productive ecosystems on the planet, feeding and sheltering otters, rockfish, abalone, and countless other species. Along much of the Northern California coast, over 95% of the kelp canopy has vanished in the last decade. What Catherine's been seeing firsthand - mile after mile - the book is now helping her make sense of.⁠

Our associate director, Natasha Benjamin, had a very tangible encounter with the consequences of global climate change this Summer.⁠
⁠
In this op-ed for The Progressive, Natasha reflects on experiencing record-breaking heat in France - and returning home to a Pacific Ocean running its own fever. From extreme heat and wildfire smoke to marine heatwaves and the loss of Northern California’s kelp forests, the climate crisis is no longer a distant threat. It’s reshaping the places we live, the oceans we depend on, and the ecosystems we love.⁠

Happy world Krill Day! 🦐⁠
⁠
These small organisms may be sitting near the bottom of the food chain, but they play a big role in our ocean's health. As the primary food source that drives seasonal migrations of thousands of other marine creatures - setting off those feeding frenzies you might have seen in nature documentaries - krill are vital not only for the survival of the species that consume them, but also the nutrient cycle as they spread carbon, nitrogen, phosphorus, and iron that they ingest from plankton on the surface to the deep ocean in the forms of excrement, molting, and vertical movement. ⁠
⁠
Krill are now threatened with marine heat waves and steadily rising ocean temperatures from climate change, ocean acidification, and industrial fishing operations; without them, we could see catastrophic loss of our ocean's species and the complete dissolution of the marine food web as we know it. So, remember to vote for the ocean and advocate for these tiny critters that make a giant contribution to our blue planet!⁠
