The Hellenic Navy (HN) (Greek: Πολεμικό Ναυτικό, Polemikó Naftikó, abbreviated ΠΝ) is the naval force of Greece, part of the Greek Armed Forces. The modern Greek navy has its roots in the naval forces of various Aegean Islands, which fought in the Greek War of Independence. During the periods of monarchy (1833–1924 and 1936–1973) it was known as the Royal Navy (Βασιλικόν Ναυτικόν, Vasilikón Naftikón, abbreviated ΒΝ).The total displacement of all the navy's vessels is approximately 150,000 tons.The motto of the Hellenic Navy is "Μέγα το της Θαλάσσης Κράτος" from Thucydides' account of Pericles' oration on the eve of the Peloponnesian War. This has been roughly translated as "Great is the country that controls the sea". The Hellenic Navy's emblem consists of an anchor in front of a crossed Christian cross and trident, with the cross symbolizing Greek Orthodoxy, and the trident symbolizing Poseidon, the god of the sea in Greek mythology. Pericles' words are written across the top of the emblem. "The navy, as it represents a necessary weapon for Greece, should only be created for war and aim to victory."...............The Hellenic Merchant Marine refers to the Merchant Marine of Greece, engaged in commerce and transportation of goods and services universally. It consists of the merchant vessels owned by Greek civilians, flying either the Greek flag or a flag of convenience. Greece is a maritime nation by tradition, as shipping is arguably the oldest form of occupation of the Greeks and a key element of Greek economic activity since the ancient times. Nowadays, Greece has the largest merchant fleet in the world, which is the second largest contributor to the national economy after tourism and forms the backbone of world shipping. The Greek fleet flies a variety of flags, however some Greek shipowners gradually return to Greece following the changes to the legislative framework governing their operations and the improvement of infrastructure.Blogger Tips and Tricks

The aurora borealis..[ 2582 ]

Northern Lights: Chasing the aurora borealis


Aurora borealis (Andy Keen)

In America "storm-chasers" are the intrepid types who pursue tornadoes, and sometimes hurricanes. But the Arctic Circle has its aurora chasers - people who speed around in search of the best views of the aurora borealis, or Northern Lights.
"Last week we saw one that had everything - spiralling, curtains, ribbons, greens and reds, and the whole sky lit up. We were amazed at what was unfolding before us," says Andy Keen.
Five years ago he left his job running a charity in the UK to move to Ivalo, a remote village in northern Lapland, Finland, latitude 68 degrees - two degrees above the Arctic Circle.
"I saw a TV documentary about the Northern Lights. So I went there to have a look. Now I'm absolutely addicted," he says.
Mr Keen's company, Aurorahunters, now takes seven tourists a week on hunting trips in the Arctic wilderness to search for the Northern Lights.
"The reason I chose here is because the population is very low, there's very little light or noise pollution, and it's perfect hunting territory for the aurora," he says. (See a slideshow here).

There are similar companies operating elsewhere in Finland and in neighbouring Norway where the official tourism website describes the aurora as "a tricky lady". It adds: "You never know when she bothers to turn up. This diva keeps you waiting."
But aurora chasers like Mr Keen are impatient - they go after the diva instead of waiting for her to come to them.
That means studying charts to find clear skies. "We look at all the weather data," he says. "We're checking the cloudiness reports. Looking at the cloud movement, the density of the clouds. We're pinpointing a place we feel at that particular time there will be a hole in the cloud."
When a location has been selected, Mr Keen and his group jump into minibuses and head into the wilderness, sometimes taking to sledges pulled by huskies to reach the most remote areas. They often see moose and bear tracks and have ventured as far north as the Arctic Ocean.
All to get the best vantage point to see the aurora borealis, named after the Roman goddess of dawn (Aurora) and the Greek name for the north wind (Boreas).
However, it's the solar wind, not the north wind, that is the determining factor.
