American Samoa Said No to Deep-Sea Mining. The US Government Doubled The Area
How To Protect The Ocean
The US government is moving toward the world's first commercial deep-sea mining lease sale, and it's happening in federal waters off American Samoa. In this episode, Andrew breaks down how we got here: a California startup's 2025 request to mine polymetallic nodules, the Request for Information process that followed, and the 75,000-plus public comments that came in during the 30-day comment window, with 80 to 98% opposed to mining. Despite that opposition, and despite a standing moratorium from American Samoa's own governor, the federal government expanded the proposed mining area from 18...

What the Wildfire Smoke in Your Sky Has to Do With the Ocean
How To Protect The Ocean
For a week straight, Andrew watched his own sky turn orange outside Toronto as smoke from nearly 900 wildfires burning across Canada, most of them following the boreal forest from the east coast to Northwestern Ontario, drifted south into the US and back again. He walks through what actually happened on the ground: which towns and First Nations were evacuated, how bad the air quality got (Toronto briefly had the worst AQI in the world), and why northwestern Ontario, not a hugely populated area but home to vulnerable First Nations communities, bore the brunt of it. Then he digs into why this...

What Lives in the Middle of the Ocean?
How To Protect The Ocean
A thousand meters down off the coast of Brazil, a deep-sea robot caught something almost no one has ever filmed alive: a giant open ocean octopus calmly eating a jellyfish. That moment, captured by the Schmidt Ocean Institute's ROV SuBastian aboard the research vessel Falkor (too), was part of a wider expedition that turned up more than two dozen species new to science, from glowing worms to glass squid to strange colonial siphonophores. The discovery points to something bigger than one expedition. The ocean's midwater, the vast zone between the sunlit surface and the seafloor, is by volume...

Oil Companies Knew Coral Reefs Would Dissolve. In 1978.
How To Protect The Ocean
In 1978, an Exxon scientist asked a question in capital letters: were the oceans dissolving coral reefs? By 1982, Exxon's own scientists had the answer, in writing. So did Shell by 1986. This episode traces a newly published Oxford University study that dug through more than fourteen thousand pages of fossil fuel industry documents and found that the world's biggest oil and gas companies understood, decades before the public did, exactly how their product would wreck coral reefs. We walk through what the industry knew and when, how a funded think tank report in 2012 was built to look like an...

Nearly 2,000 Volunteers Just Answered the Ocean's Biggest Question
How To Protect The Ocean
For more than a decade, almost 2,000 volunteers have walked California's beaches with clipboards, counting every swimmer, surfer, angler, and boat they see. It sounds simple, maybe even a little strange. But that pile of data, more than a million tally marks collected between 2012 and 2020, just answered a question marine scientists have debated for years: do marine protected areas actually work in the real world, not just on paper? In this episode, we walk through what researchers found when they finally pulled that decade of volunteer data together. We look at how the MPA Watch program...

The Silent Damage Behind Your Canned Tuna
How To Protect The Ocean
Right now, somewhere in the open ocean, a raft the size of a small table is drifting with no one steering it. It's called a fish aggregating device, or FAD, and the tuna industry drops thousands of them into the water every year to lure fish to the surface. A new study published in Science Advances tracked where these rafts actually end up, and the answer is unsettling: they've likely drifted through more than half of the world's marine protected areas by total area, with over 6,300 strandings recorded across 174 protected areas in 53 countries and territories. When a drifting FAD washes onto...

Regulations and enforcement in the swim-with-whale tourism industry are crucial for protecting humpback whales and ensuring tourist safety. The incident discussed in the podcast episode highlighted the potential dangers of close interactions between humans and humpback whales during swim tours. The humpback whale carrying a person out of the water demonstrated the unpredictability of these interactions and the need for stricter regulations.
The episode emphasized the importance of establishing clear guidelines and rules for swim-with-whale activities to prevent disturbances to humpback whales. Research conducted by ecologists, including Stephanie Stack, indicated that the behavior of humpback whales was significantly altered during swim tours, leading to disruptions in their resting patterns and overall behavior. These disturbances could have negative implications for the well-being of the whale population and the sustainability of marine tourism.
To address these concerns, it was suggested that the Queensland government should implement stronger regulations and enforcement measures for swim-with-whale tours. Currently, there appears to be a lack of specific laws governing these activities, leaving room for operators to potentially overlook important safety and conservation protocols. Strengthening regulations would not only protect humpback whales from potential harm but also ensure the safety of tourists participating in these immersive experiences.
Furthermore, the episode highlighted the need for collaboration between whale-watching companies, scientific researchers, and conservationists to develop comprehensive codes of conduct for swim-with-whale tours. By establishing industry-wide standards and promoting adherence to these guidelines, operators can minimize disruptions to humpback whales and create a safer environment for both the animals and tourists.
In conclusion, the podcast episode underscored the urgency of enhancing regulations and enforcement in the swim-with-whale tourism industry to safeguard humpback whales and promote responsible marine tourism practices. By prioritizing the well-being of these majestic creatures and implementing stringent guidelines, stakeholders can work towards creating a sustainable and ethical environment for human-wildlife interactions in the marine realm.
Humpback whales can be disturbed by human interactions, impacting their behavior and potentially affecting their population recovery. The episode highlights an incident in Australia where a humpback whale carried a person out of the water during a swim-with-whale tourism activity. This interaction, although seemingly harmless as the person was unharmed, can have significant consequences for the whales.
Research conducted by ecologists, including Stephanie Stack, has shown that commercial swimming with whale tours can lead to disturbances in humpback whale behavior. The study found that the whales made direct changes when swimmers were in the water, and the whales did not resume undisturbed behavior even after the swimmers exited the water. This disruption can have negative implications for the whales, especially since humpback whales are capital breeders with limited energy reserves.
Furthermore, the study revealed a 50% reduction in the proportion of time that whales spent resting during swim tours compared to whale watch tours. This reduction in resting time can impact the overall health and well-being of the humpback whale population. It is crucial to minimize disturbances to humpback whales to ensure their continued population recovery and the sustainability of the marine tourism industry.
The episode emphasizes the need for robust education, enforcement programs, and continued monitoring of humpback whale populations to mitigate the impacts of human interactions. Regulations and enforcement of these rules are essential to protect humpback whales from disturbances caused by swim-with-whale activities. By understanding and addressing the potential negative effects of human interactions on humpback whales, we can work towards ensuring the conservation and recovery of this species.
Collaboration between operators, scientists, and government officials is crucial for the development and implementation of effective regulations for swim-with-whale tours. In the podcast episode, it was highlighted that the incident involving a humpback whale carrying a person out of the water raised concerns about the impact of swim-with-whale tourism on humpback whale behavior.
Stephanie Stack, a researcher studying whale tourism impacts, emphasized the need for robust education, enforcement programs, and continued monitoring of population dynamics through scientific research to minimize negative impacts on humpback whales. She conducted a study in Hervey Bay where the whale-watching fleet developed their own code of conduct for swim tours, indicating a proactive approach by operators in response to research findings.
The episode also mentioned the importance of strengthening and enforcing existing regulations to ensure the safety of both humans and whales during these interactions. It was noted that while regulations exist, there is a need for additional rules to address specific scenarios, such as maintaining adequate distances and respecting whale resting times.
By fostering collaboration among operators, scientists, and government officials, a comprehensive set of regulations can be developed that considers the well-being of humpback whales and the safety of tourists. Operators can benefit from scientific insights to enhance their practices, while government officials can ensure that regulations are effectively enforced to protect marine wildlife.
Overall, the episode underscores the significance of multi-stakeholder collaboration in creating sustainable and responsible swim-with-whale tours. By working together, these parties can address the challenges posed by such activities and strive towards a harmonious coexistence between humans and humpback whales in their natural habitat.
