Ocean Conservation & Tidalpunk

I’ve been thinking of how to combine electrified reefs with open ocean aquaculture as a way of helping indigent and at-risk fisher communities to deal with climate change. Of course, there’s no technological solution to social problems, so I still have to consider the social and organizational aspects of using these technologies in indigent fisher communities.

How would you think these technologies could help coastal communities?

On a brisk winter's day in Sydney, most people find the seawater temperature near freezing.

A team of Sydney scientists are getting creative about how to provide these underwater gardens with the best chance of survival against global warming, starting with coral found in Sydney Harbour.

Using these findings, researchers will give corals what a nutritional supplement is to humans, but instead of vitamin C, it's fat.

"If corals can feed well, they've got a better chance at surviving a bleaching event."

"The window for saving the Great Barrier Reef and other reefs in the world is getting smaller and smaller", she cautioned.

Pollution cuts have diminished “ship track” clouds, adding to global warming

Heat-resistant strains of giant kelp are being planted around the Tasman Peninsula in a bid to restore the once great marine forests devastated by climate change.

Baron, who has been diving in these waters for more than 40 years, says the disappearance of the kelp has led to a wider scale collapse of the ecosystem.

With the backing of fashion-designer-turned-climate-entrepreneur Sam Elsom's Sea Forest Foundation, an initiative that hopes to help tackle the climate crisis by protecting and restoring kelp and seaweed, they began the process of planting giant kelp across more than half a hectare.

The water is surprisingly clear, and cold, and as we descend we pass over beds of golden kelp and crayweed, their honey-coloured leaves shifting in the light from above.

"We're facing the loss of kelp forests in Australia within a decade or two. That could still happen, even with what we're trying to do. But if we do nothing, you can guarantee they'll be gone. So I don't think we have the luxury of not trying."

Species like tuna and sharks are especially vulnerable to these changes.

Do you think that Final Fantasy X would count as tidalpunk? The world has a strong connection with water and for the most part its people seem to live in peace with nature (if you don't count monsters).

Also, can you recommend me anything you'd consider tidalpunk? Games, books, shows, whatever.

The sailing ship is a textbook example of sustainability. For at least 4,000 years, sailing ships have transported passengers and cargo across the world’s seas and oceans without using a single drop of fossil fuels. If we want to keep travelling and trading globally in a low carbon society, sailing ships are the obvious alternative to container ships, bulk carriers, and airplanes.

I've been learning about the cultivation of algae and cyanobacteria, and I found this guide to be an interesting read. What do you guys think about algae as a potential sustainable food source?
