Water stratify into horizons not only with different water temperatures, but also the oxygen concentration. One indicator of this phenomenon are small crustaceans that are almost instantly appear in a fresh hole.When the ice will melt water, it is more a variety of patterns. Toward the middle of the pond will still remain subglacial gluhozime and near shore cracks – Spring. One way or another, but the fish was on the move.

I know I know 21st century, hundreds of satellites over the head and all that. And the war begins, and posshibat all these satellites and as partisan if priemnichik zhpsovsky not work. Quite simply, it means we must remember antiquated methods.
If, due to a dense cloud navigate using astronomical methods fails, you can try to determine the side of the horizon to local characteristics.Here it should be noted, first, that those ways of orientation that are in the literature, for clarity, are in perfect or more exaggerated form. In nature, these signs often more blurred, indistinct, often contradictory, Read more [...]
The usual method is to find the time to sunset with your fingers. It is useful to know how much time is left until the moment when the sun will hide behind the horizon and begins to darken.

There is a very conventional method to find the time before sunset with the fingers of your hand.As a different source, all you need to do is to pull the hand so that the sun seems to lay on your index finger.

on January 18. For three nights mid-January over the southern regions of Norway appeared beautiful mother-of-pearl clouds. This is stratospheric clouds, which are formed at a height of 25 km with temperature ?85°, consist of spherical supercooled drops and resembling Cirrus. Reflecting and refracting the sunlight, they acquire the rainbow hues of the spectrum and seem to be glowing in the dark sky.

In the town Ilulissat polar night ends on January 13. On this day, here you can see the first sunrise. But this year the sun above the horizon appeared two days earlier.

Recently received a lot of messages about Halo, false or second sun light or solar poles, which are sometimes regarded as the "Northern Lights." Many saw themselves these beautiful natural phenomena. What science says about this phenomenon?Halo - is refraction and reflection of light ice crystals in clouds in the upper tier, are light or bright circles around the sun or moon (lunar sample photos halo), separated from the heavenly dark spaces. Halo often seen in front of the cyclone (in cs their warm front) and therefore can be a sign of their approach.As a rule, the halo appear as Read more [...]
Some phenomena, vision and terrestrial observers, and down stations, and astronauts "Apollo", due to the presence in the tenuous lunar atmosphere dust particles. But no one can explain how they got there. May shed light on the probe LADEE, which will launch in August 2013.You have heard about the new restaurant on the moon? Lovely food, but no atmosphere.This joke for decades, and, admittedly, it is outdated. In the future, NASA sends probe to orbit the Moon, which will gather information about the atmosphere of our satellite, including the situation near the surface and environmental Read more [...]
Despite the fact that he is one of the brightest objects in the night sky, Mercury - a planet that experienced amateur astronomers observed quite often. In the next couple of weeks, however, observers from the northern hemisphere will have the best opportunity in 2013 to consider a small luminous spot Mercury in the evening sky.Feature observations of Mercury is that you should first find a place to watch the western horizon with unscreened, wait half an hour after sunset to dark, and then bring the binoculars at the sky, which lies just to the left of where the sun disappeared.

I'm sure many own simple devices of the north, south, east and west. Knowing the position of at least one side of the horizon, it is easy to identify and all the others: If one faces north and hands out to the sides, the left point to the west, the right - to the east and south is behind. Determine the side of the horizon can be the compass, the sun, the stars, the natural signs.
Compass. It is best to carry a compass with a mobile vizirkoy, dial with luminous at night and arrow. In order to determine the side of the horizon, omit brake magnetic needle compass and set horizontally. He Read more [...]
The purpose of this paper is to attempt to get a little further than we normally allow horizon - where the outside one can see a clear forecast hazy outlines various options. I believe that real explicit forecast horizon, which we can do with great certainty, is 5 years old, while the space beyond the horizon, where we can observe different features, is 20 years after that point. And for this moment to be totally unpredictable. I will try to justify it.
Rating 5 years originated from an extrapolation of historical periods which in the past, the world situation has changed so that the particular Read more [...]
ORIENTATION FOR THE STARS
Cloudless night side of the horizon is most easily identified by the North Star, always pointing in the direction to the north with an accuracy of 1 °. To find in the sky this star located in the constellation Ursa Minor, it is necessary to find the Big Dipper, which is represented in the form of a huge, well-marked bucket of seven bright, far removed from each other stars. If the two stars at the end bucket draw an imaginary straight line, and the distance between them to defer on this line 5 times, at the end of the last segment will be visible star is soft - this Read more [...]
Target areas - means being able to find your location and direction motion with respect to the horizon. Orientation consists of three main steps: a) the identification of areas by landmarks, and b) the definition of the horizon, and c) determining the point of location and direction of travel before reaching the landmark.
Terrain orientation begins by defining the horizon. Side of the horizon are determined by the compass, celestial bodies, local subjects and different features. Identification of local objects only gives approximate results, so use this method recommended in exceptional cases Read more [...]
In practice, the most common tourist compass Hadrian. It consists of a round box, inside of which on the edge of a steel needle placed magnetic arrow. On the inner surface of the box marked degree scale divisions. Kettle closed fortified rotating lid, with a device for viewing-slot and fly. In determining the horizon, measuring and setting aside a compass to orient the corners. For this door should release the brake, to combine the northern end of the arrow with zero limb. In this position, the side of the horizon will be located in the direction corresponding to the initials marked on the Read more [...]
I walked, with his heavy rifle on shoulder, one hand on the neck of the stock, and the other by the barrel. So himself in the neck arms to push, and go seemingly easier. Self-deception, of course. On the right the sea, left the reeds, my eyes used did not see them. The place was once in a special desert, only rustling reeds in the wind but the splash of water in the way.
