We’re calling on EU decision-makers this #EUOceanWeek to defend the deep and support a precautionary pause on deep-sea mining and an end to bottom trawling on high-seas seamounts by 2027.

From the surface to the seafloor, we must protect our ocean.

Marine National Monuments and Sanctuaries: Reminders of Our Shared Past and Connected Future
The Papahānaumokuākea Marine National Monument would stretch from Manhattan to Omaha if laid out across the continental United States. Yet, you may never have heard of this diverse oceanic site in the Northwest Hawai’ian Islands, which encompasses more than 500,000 acres of pristine coral atolls, seamounts, prime seabird nesting habitat and sites sacred to native Hawai’ians. Conversely, on the other side the Pacific, and much more accessible to most of us, every year the Monterey Bay National Marine Sanctuary hosts thousands of visitors, people coming to dive, fish, surf or just to poke through the region’s tidepools. The United States boasts five marine national monuments and 18 national marine sanctuaries, together hosting over 42 million visitors a year and safeguarding valuable historic and natural treasures. From remnants of more than 100 World War I wooden steamships at Maryland’s Mallows Bay-Potomac River and the vibrant coral reefs of Flower Garden Banks off the coast of Texas and Louisiana, to the deepest spot on earth at the Marianas Trench National Monument, these places serve many purposes -- from protecting seabird habitat and forage fish to honoring cultural heritage and supporting local coastal economies. Congress or the president can designate marine and land-based...

The new Ocean Protection Gap Report finds ~10% of the ocean is designated protected/conserved, but just 3.5% is effectively protected 🌊

Protecting seamounts could safeguard 21% of the global seabed. If we’re serious about 30×30, the UN Bottom Fisheries Review must turn commitments into action.

Join SOI to learn from scientists who have studied seamounts in Chile & on the high seas discussing seamount ecology, what they have learned so far, & what remains to be understood. Dr Jyotika Virmani will also spotlight a seamount discovered during the Nazca Ridge expedition in 2024.

'The figures have reignited debate around bottom trawling on sensitive marine ecosystems such as seamounts, with conservation groups warning the official tallies under represent the true extent of ocean floor destruction.'

#FishADay Scalicus engyceros An armored searobin with no English common name. Benthic, deep Pacfic, often associated with seamounts. Skitters along the seafloor on spidery "legs" that are actually modified pectoral fin rays.

The Rift Ocean is scattered with deep trenches, while in the Seamounts Ocean there is more volcanic activity and seamounts.
The Polar Ocean is around the south pole and it partly connects with the other two.
#sedimentarylands #worldbuilding
#SeptemberWorldbuilders, what are some facts about your world's ocean? Has it been explored or are there unmapped parts still? Do tides work similarly to how they work in the real world? Do you have any undersea volcanoes or cool geologic features worth noting?

🌊 We welcome the Balearic Parliament's support for a National Park in the Canal de Mallorca and the strict protection of its seamounts.

Oceana helped secure #Natura2000 status for the area through scientific expeditions and first proposed a National Marine Park here in 2017.
