Davis Strait, Canada
Some of the greatest depths in the eastern Arctic are reached in the southern end of Davis strait. The surface waters are strongly affected by counterclockwise-flowing currents.
Along the west side, an outflow of cold water from the Arctic Basin moves south, at flow velocities of 8-20 km/day, to feed the Labrador current. On the east side the west Greenland countercurrent brings warmer water north. Ice conditions reflect this flow regime, with heavy ice movement and icebergs along the western shore, contrasting sharply with more open water along the Greenland side.

Manual Scavenging: Nations Shame .
By Sunil Kuksal .

The social, cultural and economic realities of modern India unfold a series of paradoxes. While a parliamentary law bans the manual scavenging and the government approves projects to wean the underprivileged section away from this dehumanising occupation, cruel caste apartheid and brutalising poverty perpetuate the practice. Furthermore, neo-liberal economic policies restrict alternative possibilities of having a dignified livelihood. .
The term manual scavenging describes the daily work of manually cleaning and removing human faeces from dry (non-flush) latrines across India. Workers, mostly women and young boys, are also referred to as night soil workers, a Victorian euphemism that hides the repugnance of the word shit. In India, manual scavenging is a caste-based occupation carried out by dalits. The manual scavengers have different caste names in different parts of the country: bhangis in Gujarat, pakhis in Andhra Pradesh, and sikkaliars in Tamil Nadu. These communities are invariably placed at the bottom of caste hierarchy, as well as of dalit sub-caste hierarchy. Using a broom, a tin plate and a drum, they clear and carry human excreta from public and private latrines, more often on their heads, to dumping grounds and disposal sites. Though considered illegal, manual scavenging is forced onto dalits by caste pressure. .
Scavengers earn anywhere between Rs 20 to Rs 160 a month and are exposed to the most virulent forms of viral and bacterial infections that affect their skin, eyes, limbs, respiratory and gastrointestinal systems. Official figures show that there are still 3.43 lakh scavengers in the country. A 2002 report prepared by the International Dalit Solidarity Network, including Human Rights Watch (United States), Navsarjan, (Ahmedabad, Gujarat), and the National Campaign on Dalit Human Rights (NCDHR), gave estimates of one million dalit manual scavengers in India.
