More than 100 years before has
sailed by since the luxury steamship RMS Titanic met its catastrophic end in
the North Atlantic, plunging two miles to the ocean floor after sideswiping an
iceberg during its first ever voyage. Therefore, the intended Port of New York, a
deep-sea grave became the pride of the White Star Line’s concluding destination
in the early hours of April 15, 1912. It is believed that over 1,500 people
lost their lives in this disaster. In the decades since her demise, Titanic has
inspired countless books and several notable films and pictures while
continuing to make headlines, mainly since the 1985 discovery of her resting
place off the coast of Newfoundland. Here you’ve a chance to look into some of
unique pictures of Titanic, which is very rare indeed.

Kilauea, Hawaii
Kilauea is a currently active shield volcano in the
Hawaiian Islands, and the most active of the five volcanoes that
together form the island of Hawaii. Located along the southern shore of
the island, the volcano is between 300,000 and 600,000 years old and
emerged above sea level about 100,000 years ago. It is the second
youngest product of the Hawaiian hotspot and the current eruptive center
of the Hawaiian–Emperor seamount chain. It's name means "spewing" or
"much spreading" in the Hawaiian language, referring to its frequent
outpouring of lava.

Norway’s most beautiful waterfall Vøringsfossen
Vøringsfossen dazzles tourists with its multiple
waterfalls all converging at the head of Måbødalen in Hardanger.
Although there are numerous ways to experience the waterfall and the
vertical-walled valley, most people will view the falls from the upper
and lower lookouts.A path from the scenic national tourist route through
Hardanger (Rv 7) leads to the foot of the waterfall. The old road,
constructed between 1887 and 1924, winds up the mountain side in 125
hairpin bends - an impressive piece of road engineering.There are
several possibilities for photo stops, picnics and activities in the
near surroundings.
The Hardangervidda Nature Centre in Eidfjord is situated at the bottom of the Måbødalen Valley. The centre has exhibitions from the vast mountain plateau of Hardangervidda, as well as hands-on activities and a cinema.

“Brine Pools” An Under Water Lake in Ocean Basin
A brine
pool is a big area of brine on the ocean basin, and their pools are bodies of
water that have salinity 3 to 5 times greater than the surrounding ocean. For
deep-sea brine pools, the source of the salt is the dissolution of large salt
deposits through salt tectonics. The brine pool is quite often contains high
concentrations of methane, furnishing energy to chemosynthetic animals that’re
mostly live near the pool, and these creatures are habitually extremophiles. Brine
pools can be found around the world, and are well-documented in the Gulf of
Mexico.
Moreover,
Brine pools are also recognized to exist on the Antarctic Shelf where the
source of brine is salt excluded during formation of sea ice. Therefore,
deep-sea and Antarctic brine pools can be very toxic to marine animals. Brine
pools are sometimes called seafloor "lakes" because the thick brine
does not easily mix with overlying seawater. However, the brine density is
increase due to high salinity, which produced a distinctive surface and
shoreline for the pool. Hence, when submarines dive into brine pools, they
float on the brine surface due to the high salinity density.
Though, the
motion of a submarine can form waves across the brine-seawater interface that
wash over the surrounding "shoreline". Moreover, deep sea brine pools
every so often coincide with cold seep activity and methane released by the
seep is processed by bacteria, which have a symbiotic connection with seep
mussels living at the edge of the pool. This ecosystem is mainly dependent on
chemical energy, and unlike almost all other life on Earth, has slight
dependence on energy from the Sun. So, finally It requires a submersible
to down thrust to actually penetrate one of these pools, thus equipment, such
as a submersible, can actually float on its surface.
