NEARCHUS: Spread of Smoke Across Canada..[ 1414 ]

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.

Carbon Monoxide Levels Trace Spread of Smoke Across Canada

Fires in the Northwest Territories filled Canadian skies with smoke in late June 2010. This map shows concentrations of carbon monoxide—one component of smoke—from June 23–28 across Canada and the northern United States. Places where concentrations of carbon monoxide were highest are red. Places where no measurements were made (usually due to clouds) are gray.
Fire activity was concentrated west of Hudson Bay, and smoke wafted southeast toward the Great Lakes. Additional pockets of high carbon monoxide concentrations southeast of Hudson Bay may have been transported to the area from the Northwest Territories, but they may also be from local fires.
Smoke from fires can contribute to poor air quality far from the fire itself. It can mingle with urban pollution and boost air quality to unhealthy levels in cities. Carbon monoxide is a good tracer for moving smoke plumes, even across large distances.
Satellite observations, such as these data from Canada’s Measurements of Pollution in the Troposphere (MOPITT) sensor on NASA’s Terra satellite, can be fused with ground observations of pollution in models to figure out how forest fire smoke may affect air quality at places downwind of fires.
