A recent University of Hawaiʻi at Mānoa report analyzed impacts to the ocean based on different CO2 emission levels. It found that even if carbon dioxide production flatlined by the middle of the century, nearshore waters will experience significant acidification, though oceanographers say reducing emissions is still important.

University of Hawaiʻi oceanographer Nick Hawco spoke to The Conversation's Maddie Bender about new research into the North Pacific Transition Zone.

Bob Richmond, a coral scientist and head of the University of Hawaiʻi Kewalo Marine Laboratory, spoke to HPR about the science behind protected areas like the Pacific Islands Heritage Marine Reserve.

The state Board of Land and Natural Resources voted to move forward with an initiative to raise and preserve native and endemic limu species in Hawaiʻi.

The Trump administration says it will consider selling leases to extract minerals from the seabed off the South Pacific island of American Samoa. It's a potential first step in a wider industry push to allow deep-sea mining that environmentalists oppose because they say it could irreparably harm marine ecosystems.

Environmental advocate Solomon Pili Kahoʻohalahala spoke to The Conversation's Maddie Bender about ocean protections amid Trump's executive order for deep-sea mining permits.

The Conversation spoke with renowned oceanographer Sylvia Earle, a former chief scientist for the National Oceanic and Atmospheric Administration, about the effects further cuts to the agency could have on access to essential information.

Should Hawaiʻi ban octopus farming? The practice is already almost nonexistent around the world, and a facility in the Canary Islands is one of the few with actual plans to raise them for food. HPR's Mark Ladao has more.

Every year, several tons of debris from the North Pacific Garbage Patch ends up on Hawaiʻi's shores. Scientists have developed a model to track the floating trash heap.

The state Board of Land and Natural Resources has extended a temporary fishing ban for the pākuʻikuʻi, also known as the Achilles tang, until the end of 2026.
