It’s a weeping rock. Sandstone blocks near the Lakes Entrance holiday resort on the coast of Victoria, south-east Australia, are covered with barnacles that look like they are spilling tears. How did those so called “Tears of the Virgin”, get there?
The collection of limestone stacks known as the Twelve Apostles are one of the highlight attractions along the Great Ocean Road. Over 20 million years ago these stacks were attached to the mainland, before wind and waves eroded the cliffs, carving them into caves, then into arches, before ending up as columns.
The Twelve Apostles are a part of the Port Campbell national park.Other destinations along this coastline include Loch Ard Gorge, The Gibson Steps, The Grotto and the London Arch.
I Recently read About these amazing glow in the dark creatures in the newspapers and thought it was worth sharing
1. Saprobe Panellus Stipticus, Fungi:
Found in Asia, Australia, Europe and North America, the bioluminesence emitted by the Saprobe fungi tht grows on decaying wood is called Foxfire (not fiefox).Also called fairy fire, it emits green light.
2. Firefly Squid (Watasenia Scintillans):
Japan’s tiny “Firefly” squid emits a blue bioluminescence. These emissions allow the firefly squid to communicate with other members of its species, warning them of predators and to lure fish into its bait.
Found in the Caverns of New Zealand and Australia, glowworms not only emit light to attract prey, but drop sticky silken thread from cave ceilings. This thread creates a cool visual effect similar to looking at the stars on a clear night.
4. Crystal Jelly ( Aequorea Victoria):
Found off the coast of North America, Crystal Jelly amits a green-blue glow with over 100 tiny, light-producing organs surrounding the body. It is collected for its luminiscent photo-proteins which are used as bio-markers in research studies on genes and to detect calcium.
Found in both fresh and salt water, Dinoflagellates can produce a brilliant bioluminescence. When they are disturbed, either naturally or by man-made waves(boats, swimmers, fishermen) the water surface lights up with a beautiful blue glow.
Mysterious green ice spotted in Antarctica by NASA's Operational Land Imager!
A mysterious feature has been spotted in Antarctica’s Granite Harbor – a bay off the coast of Victoria Land – which spreads over an area of 26 km (14 nautical miles), located in a cove near the Ross Sea.
Jan Lieser, a marine glaciologist from Australia’s Antarctic Climate and Ecosystems Cooperative Research Center believes: “The green color is caused by phytoplankton at the water’s surface that have discolored the sea ice. These microscopic marine plants, also called microalgae, typically flourish in the waters around Antarctica in the austral spring and summer, when the edge of the sea ice recedes and there is ample sunlight. But scientists have noticed that given the right conditions, they can grow in autumn too."
The microscopic marine plants, phytoplankton, are an important part of the marine food chain, which is a source of nutrients for sea creatures such as whales, jellyfish, shrimp and snails.
This is not the first time such a discoloration, caused by microscopic plants, is being observed in an icy area.
In 2012, Lieser and his colleagues observed a similar phenomenon off East Antarctica’s Princess Astrid Coast. The late blooms were confirmed and measured by an Antarctic research ship.
Various factors like sunlight, wind, sea ice, predators and the availability of nutrients are responsible for the growth of plankton in enormous quantities, which means they can even be seen from space.
"In early 2017, there was not much ice anchored to the shoreline [fast ice], a condition that is thought to help ‘seed’ phytoplankton growth. But offshore winds and sunlight favorable for growth made conditions similar to previous years that supported blooms, according to Lieser,” the NASA statement revealed.
