The often lovely line of interesting seaweed, driftwood and things to find left behind by the waves at the top of high tide. Hopefully, not too much plastic.

More lines: browse line, plimsoll line. draw smooth lines. choose the fast line, the coastline paradox

More beaches: surfing breaks, beaches—amazing for play, gastropods, sea jelly—sea star.

Strand line

There are only two double-landlocked countries: Liechtenstein and Uzbekistan. Their claim to fame is that not only are they landlocked with no access to the high seas themselves, but they are also surrounded by countries that are themselves landlocked. Another way to put it is that you have to cross two national boundaries before you can reach water connected to the oceans.

Double-landlocked countries

If you were to dig straight down from where you’re standing and pass straight through the centre of the Earth and keep on digging — you’d now be tunnelling up I guess — where you come out would be your antipode. Though most of them would first have you springing a leak at the bottom of the ocean, so be careful.

Antipodes

I’ve never used one, but I’d love to. They seem a little like magic. Basically, you pressurise the air of an underwater box enough to keep the water from coming in. This enables you to have a kind of swimming pool entrance to water even though you’re already actually underwater. So cool.

Moon pool

Not the easiest switch to make but given that jellyfish and starfish are not at all fish there is a move to call them sea jelly and sea star. As long as we all work to help protect them clearly it doesn’t matter a whole lot, but I think the move to sea jellies and sea stars makes good sense alongside others like the sea horse, sea cucumber, sea lion, sea lily, sea gooseberry…well, actually the sea horse is a type of fish, but you get the idea.

Sea jelly, sea star

Bycatch makes me sad. Any fish or sea creatures can be caught unintentionally during fishing, and it also affects larger animals such as sharks, turtles and of course dolphins. When learning from a whale shark expert on the island of Utila in Honduras he told us one of the simplest ways to help is to give up eating prawns. As London’s Maritime Museum puts it:

“For every kilo of tropical prawns you buy, 15 kilos of unwanted sea-life may be thrown back dead as ‘by-catch’. Trawling for prawns can also trap turtles, unless a special device keeps them out of the nets. Farming prawns is often no better, since mangrove swamps may be destroyed to make room for prawn ponds.”

Prawns are particularly bad as they are often caught with bottom trawling. I once read a description of it as wanting to catch a cow, and choosing to drag a net by helicopter over the entire farm, and so also catch the tree in the garden, the dog, the pigs and the farmer’s wife in the process.

Check out the WWF bycatch page for more including a bottom trawler in action.
