The problem is underwater too


The first news I had about the devastation the tsunami caused in the underwater habitat was just one day after the tsunami when a TV station interviewed one Spanish survivor in his hospital bed at Phuket. He works, or used to work before the quake, as a scubba teacher at Khao Lak and he pointed out that the NGO's should also keep an eye to the damage the tsunami caused to the coral reefs that surround the coasts of the countries afected by the disaster as they where the mean of life of the inhabitants of these areas, either tourist or fishery dependant.

I must say that I stored it in some hidden place of my head and didn't think about it until Prentiss said something about it in his comment.

I have researched a bit more into the subject and have found what I expected, the studies say that the devastation caused to the underwater marine life can affect near shore fishery for decades, just the time the ocean floors will take to recover from the damage received and the diseases a massive alteration bring to an ecosystem.

According to this article it seems that the natural underwater walls coral reefs are have saved thousands of lives. Just another reason that should make us give a bit of our time to recover the lost underwater habitat.

More news: here

Note: As the ocean floor has changed significantly, global maps like sediment thickness or some maritime routes as several naval channels have completely changed.

Note2: I just heard a UNESCO report on the radio advising that some Han and Tang dinasty wreckages might have been lost or severely damaged. It's bad news for archeology too then.

Since we're on the subject of sea level rise and archaeology, I'd been hearing for a few years about big underwater archaeological finds here and there, notably in the Mediterranean and around India. I'd always wondered what that was about -- did so many ancient cities subside to below sea level? It turns out that the cities didn't go down, rather the sea levels rose. Go back just a few thousand years in the archaeological record and you hit a time when glaciers had enough water tied up in them that sea level was significantly lower. The biggest cities of the ancient world, or the coastal ones anyway, are all underwater now.

There's a lot of speculation attempting to tie this fact to the origin of legends about floods or Atlantis. Be that as it may, it's a reminder that our coastlines are not fixed boundaries -- they've moved even in historic timescales, and in geological ones they're in constant flux.

My humble opinion is that it may be to soon to quantify the effect of the tsunami on the reef barriers, they have been there for thousands of years, this is not the first major event they endure.

In places like Cancun the effects of the two hurricanes have been of benefit, they clean up the mess the humans leave behind.

Well, this is interesting. I did a blog search for creatine and caffeine and found your site. When I get some time I'll come back and find out where creatine and caffeine appears and how it relates - if it even does. Take care - nice work.
