Hi JF Aus

Algae and submarines both dwell underwater - so I may get interested :)

Cheers

Pete

Algae are a very diverse group of generally simple unicellular or multicellular eukaryotic organisms. Most of them are autotrophic which means that they can harvest carbon dioxide from the atmosphere and convert it to organic matter.

They inherited their photosynthetic apparatus from cyanobacteria. Cyanobacteria are sometimes called blue-green algae but they are prokaryotic organisms and are not true algae. Some cyanobacterial species are used as food as well.

Seaweeds are edible algae that have been used for centuries as food in many coastal regions all over the world. They may belong to one of three groups of multicellular algae: red, green or brown. In countries such as China, Japan, Korea and to some extent Iceland, Ireland, Chile and New Zealand algae are part of people's regular diet. They are usually of marine origin since freshwater algae are often poisonous.

Algae are of excellent nutritional value since they contain complete protein (in contrast to plant food harvested on land), fiber, and sometimes high levels of omega-3 fatty acids. In fact, the omega-3 acids in fish comes from the microalgae consumed at the bottom of the food pyramide and gradually passed up to the fish at the top. Algae are also rich in many vitamins, such as A, C, B1, B2, B3 and B6, as well as minerals, such as iodine, calcium, potassium, magnesium and iron. They are consumed both cooked, dried and raw.

plantagenet, I think you are already interested and the following should make you much more interested.

As for submarines I have Gold Coast City Council approval in principle to develop an underwater submarine rail tourist ride off Surfers Paradise CBD. 4 x 50 seat subs, and to regenerate seagrass in The Broadwter.

Plus I have traveled about 400 kilometers feet first backwards underwater inside a torpedo sized lure, to film for the first time, giant black marlin attacking to feed.

The ocean is a big place requiring big ideas.

A more recent proposal is a 2,000 km long submarine-like tube, aqueduct to transport presently wasted water, south to farmers and the water starved Coorong.
The Coorong is supposed to be feeding biodiversity in the southern oceans.

It's a multi billion dollar "productive development", all steel aqueduct. Steel suppliers and submarine engineers and fabricators, surveyors and planners, all university graduates, should be very interested

Nothing sensible is impossible.

You see plantagenet, there is now dire urgent need to manage nutrient and algae and the most likely viable way to achieve that goal, involves new productive and viable food and fibre export business for the nation.
Prove me wrong if anyone can.

doog, why do you think algae aren't plants?

As for the article, think tanks are absolutely crap at advancint knowledge because they don't make a proper distinction between genuine knowledge and the disinformation that their corporate backers want people to believe. They don't have the proper peer review process that universities do.

MOOCs are great, but I wouldn't want to rely on them for everything.

Unfortunately for algy kelp, it is currently being decimated by a black fungus. I've been watching large areas of kelp beds disappear over the years, and turning into dead sticks..the ocean equivalent of die-back in eucalyptus forests...

The trouble with the eucalypt here in Victoria is the missal toe bird. Spreading its food supply around. Thirty % missal toe on a gum tree will kill the gum while the missal toe survives.

It is said that the parasite missal toe uses more water and the gum tree gets none.

Cut it of and the tree is fine. You would need a chopper to do it.
