Everyone, it’s World Octopus Day 🐙 !

How could I not share this gorgeous dumbo octopus? 🥰

There are actually 17 species of dumbo octopus, each sporting fins that look a bit like Dumbo the elephant’s ears. They live in the deep, deep sea. As far as we know, none of them has an ink sack!

Indonesia is moving to designate 17 seagrass habitats as strategic areas for blue carbon, a plan that promises climate & community benefits but raises concerns over safeguards.

Experts welcome the initiative but warn it must avoid privatization, ensure fair benefit-sharing & guarantee transparency.

Indonesia eyes seagrass zoning for blue carbon; experts urge community benefits

Indonesia’s push to legalize a blue carbon zoning plan that’s focused on seagrass has sparked optimism for climate solutions, but some experts debate its risks and safeguards. The Indonesian Marine…

Damn. This is amazing. £325 per week, paid monthly, for 3 years - and the result was a profit for the Irish economy:

Post from Threads user rodneyowl: "Ireland has declared the Basic Income for Artists scheme permanent. This will be officially announced in tomorrow’s budget. Details to follow. Congratulations to all who fought for it and the present and future artists of all sorts in Ireland. That includes me 👌We’re just comin to the end of a 3 year pilot scheme. It’s been a roaring success. For every €1 paid out to the 2000 participants, the government got €1.46 back. Can’t argue with that. Other countries are already taking note."

🐟"Only 41% of the UK’s commercial fish populations have been found to be healthy. 1/4 are being fished beyond sustainable limits. 1/6 are both critically low & yet still being overfished"

Half the UK’s fish stocks are overfished – but the evidence shows how they can be revived

Overfishing affects food security, blue economy jobs and climate resilience.

Carbon offsets fail to cut global heating due to ‘intractable’ systemic problems, study says

If Russia cuts submarine cables in international waters, can they be found guilty if a neighboring country catches them at it? Apparently the answer is no because there's no jurisdiction. Which leads to a new question, who is responsible for creating one? The UN?

Among their approaches - restoring and caring for:
⛱️ Beaches
🟡 Dunes
🦪 Shellfish reefs
🔵 Wetlands

These nature-based solutions won't stop sea level rise completely, but they'll help safeguard infrastructure and communities - and provide critical habitats for wildlife!

Virginia Beach, USA, is particularly vulnerable because it is low-lying and right next to the mouth of the Chesapeake Bay estuary.

But the city is meeting the challenge head-on with their cleverly titled "Sea Level Wise Adaptation Strategy."

#DYK hundreds of cities around the world are at risk from sea level rise and flooding?

Yeah, not great news, but there are things cities can do to reduce the impacts and adapt

Since today is World Habitat Day, what better time to highlight one doing it right!

Some of our recent maps were reviewed for Geology Today & we're pleased to see the positive opinions & appreciation of how much work goes into them 🎉 doi.org/10.1111/gto....

The maps include The South Orkney Islands, Alexander Island, and Bedmap3. Details available in our catalogue - bas.ac.uk/maps

The front cover of our South Orkney Islands and Signy Island map. There is a photo of the landscape on Signy, with a tall, crevassed glacier in the foreground (Orwell Glacier), and clouds and snowy mountains in the distance.

The front cover of our Alexander Island map. The photo on the cover shows a faded red tent, with snow-covered, craggy mountains in the background.

The front cover of our Bedmap3 map, which shows an extract of the map (without any of the labels). The terrain of the land beneath the ice is shown with a coloured hillshade, ranging from dark blue (deepest) to light brown and white shades (tallest).

Emperor penguins are capable of diving to 500 meters (1600 ft), remaining underwater for 30 minutes at a time.

They'll spend up to 50-75% of their lives in the water, diving for fish, krill & squid.

Diving is in their blood... in a very specific way.

Let's talk about PENGUIN HEMOGLOBIN.
