The strait was first explored by John DAVIS, leader of three voyages 1585-87 organized by merchants of London, England.

Davis Strait, situated between BAFFIN ISLAND and Greenland, is the entrance to BAFFIN BAY from the North Atlantic. It is a large stretch of water over 950 km across at its greatest width and never less than 300 km wide. At the narrowest point, its submarine topography consists of an undersea ridge, a continuation of the mid-Labrador ridge, extending from the coast of Baffin Island to Greenland. The shallowest waters in the strait are found along this sill, from 350 to 550 m deep, before plunging down to abyssal basins on either side.
Some of the greatest depths in the eastern Arctic are reached here (3660 m) in the southern end of the 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.
Recently, Zhengzhou Jiutian completed the production of avocado pomace dryer equipment customized for South African customers, and completed the loading and delivery on March 30, and delivered it to a logistics company. The equipment is used for avocado pomace processing of a company in South Africa.
The avocado pomace dryer produced by Jiutian can well dry pomace (apple pomace, tomato pomace, pear pomace, etc.), corn pomace, feed, protein powder, etc. Avocado pomace is not easy to dry, because most of the moisture exists in the interior, and it cannot be dried at one time, otherwise the nutrients will be lost. The new type of avocado pomace dryer produced by Zhengzhou Jiutian is a kind of tumble dryer, with compact structure, large pressing force and high output. According to the physical properties of avocado pomace, the countercurrent drying technology is adopted, which can quickly dry the wet pomace with a moisture content of 80% to a dry product with a moisture content of less than 13%. The dried material has good color, no paste, and no loss of nutrition.
We will continue to report on the follow-up progress of the project. If you are interested in our dryers, please feel free to contact us.

In the photo, one of many ways animals regulate their body temperature is on display. The hippo is bathing in water in order to stay cool on a hot day. Bathing is an evaporative mechanism that many animals utilize. Additional ways animals control heat exchange with the environment include insulation, circulation, countercurrent heat exchange, evaporation, behavior, long-term behavior, and metabolism. The photo was taken at the Denver Zoo.

The Arctic Fox - Vulpes lagopus, lives in some of the most frigid extremes on the planet. Among its adaptations for cold survival are its deep, thick fur, a system of countercurrent heat exchange in the circulation of paws to retain core temperature, and a good supply of body fat. The fox has a low surface area to volume ratio, as evidenced by its generally rounded body shape, short muzzle and legs, and short, thick ears. This arctic fox is a resident of the Point Defiance Zoo and Aquarium.
