June 11 – Discovery of a Great Reef

Posted on June 11, 2016


The Great Barrier Reef from space
The Great Barrier Reef is a gorgeous place, by some definitions the largest living thing on Earth, visible, even, from space! Thousands and thousands of different sorts of species – from dolphins and dugongs to fish and sea snakes, from sea turtles and sea grasses to mollusks and crocodiles, from sponges and anemones to sea stars and seaweeds, and of course thousands of corals – live on the reef.

It does not seem like it would be difficult to discover such a huge thing – and it seems like the discovery would be a fun and beautiful thing.

But...

The Great Barrier Reef is located off the coast of Australia, a place very far from and indeed not yet discovered by European explorers. And the discovery wasn't so much of a “Oh, look! How beautiful is that!” as it was a “Oh, no! What did we run into???”

On this date in 1770, English explorer and naval officer Captain James Cook “discovered” the Great Barrier Reef the hard way – by running his ship The Endeavor aground on it!

Once your ship is aground, it's not so easy to fix the problem.

After being stuck for an entire day, Cook and his crew finally freed their ship by throwing overboard 50 TONS of stuff. Then they still had to repair the damage. And only then could they get back to following their super secret orders: to search for a major southern continent and claim it for England.

A couple of months later, Cook would discover and explore Australia and New Zealand. Even though the former is considered a southern continent, it wasn't the huge landmass that so many people thought MUST exist to balance out the Earth. (Have you ever noticed that there is way more land in the Northern Hemisphere than in the Southern?)


Now, what about that reef?

Here are some of the kinds of species that live on or near the reef:



dugongs

30 species of whales and dolphins

saltwater crocodiles

17 species of sea snakes

6 species of sea turtles

7 species of frogs

125 species of sharks/stingrays/skates

49 species of pipefish

9 species of seahorses

more than 1,500 other species of fish


215 species of birds

5 species of marine spiders

more than 20 species of marine insects

more than 5,000 species of mollusks, including octopi and squids

more than 630 species of sea stars and sea urchins

about 1,300 species of shrimp, crabs, and krill 


more than 100 species of jellyfish


40 species of sea anemones

about 720 species of sea squirts – or ascidians

more than 300 species of “moss animals” - or bryozoans

more than 400 species of corals

about 500 species of worms

about 1,500 species of sponges

15 species of seagrasses

about 500 species of seaweeds

Constitution Day in Pohnpei, Micronesia

  Micronesia is the name for a large chunk of the western Pacific Ocean that is scattered with hundreds of small islands. (This region is near Melanesia to the south, Polynesia to the east, and Indonesia and the Philippines to the west.) One of the largest islands is Pohnpei. The Micronesian islands were settled about four thousand years ago, and at one time there was an empire centered on the island of Yap. However, in historic times European and Asian powers fought over, and sometimes took over, various islands. 

Since 1986 the Federated States of Micronesia is now an independent, democratic country of only 702 square kilometers (271 square miles) scattered over many different islands. (Not all the islands in the Micronesia region chose to join the federation.) Pohnpei is one of the four states of FSM, and the capital city of the country, Palikir, is on that island. Island with the Most-est Not only is Pohnpei the largest island in FSM, it is:
  • the highest,
  • the most populated,
  • the most developed,
  • the wettest (the only wetter place on the entire earth, according to Wikipedia, is Mt. Wai'ale'ale on the Hawaiian island of Kauai),
  • one of the most welcoming of outsiders,
  • one of the best surfing spots in the world,
  • and one of the best examples of biodiversity. That just means that there are a lot of different sorts of plants and animals on the island and its barrier reef.

Pohnpei is also the site of a ruined offshore city called Nan Madol, the Venice of the Pacific. Built between 800 and 1500 C.E. (A.D.), it is made up of many artificial islands linked by canals.




Umm...what's a Barrier Reef? Coral reefs are fairly common off the coasts of continents and especially islands in tropical areas. They are colorful sea habitats that are stony turrets, mounds, and plantlike structures created by living coral animals (tiny relatives of jellyfish). They are wonderful places for many different sea creatures to live and hide and hunt, and they are terrific places for humans to visit by snorkeling or scuba diving. A barrier reef is a coral reef that is built up near or partially around an island, with a deep lagoon between the land and the reef.
