Depth sounding maps. Fishing map of depths, holes and fishing spots on rivers, seas and oceans

For hundreds of years, the only way to measure ocean depth there was a weight, usually lead, with a thin rope. Not only was this method time-consuming, it was also highly inaccurate. Ship drift or water currents could pull the rope away at an angle, making depth measurements inaccurate. Then the ropes were replaced by echo sounders (sonars). Bathymetric studies have shown that the topography of the ocean floor is very diverse. Hidden underwater are plains, canyons, active and extinct volcanoes, and mountain ranges.

In 1978, an experimental satellite was launched to study the oceans. One of the amazing discoveries then was the fact that the surface of the ocean is not “flat”, but falls and rises in different areas. When the ocean surface was mapped, it turned out that the lows corresponded to depressions on the sea floor, and the highs corresponded to sea mountains and mountain ranges. Over time technical capabilities have increased. Satellites appeared and were compiled detailed maps the depths of the entire world ocean.

The reason for these drops and rises in the ocean surface is in the Earth's gravitational field. This is the gravity model created by the GRACE satellite:

As a result of the painstaking work of satellites, other interesting maps. This amazing infographic visualizes the world's deepest places. There is also Lake Baikal, which can be compared with other deep lakes in the world.

But finally all the secrets of the ocean topography were discovered with the help of satellites such as Jason-1 and Jason-2.

Satellite altimeters measure sea surface elevation and other features of the ocean surface. Using emitted microwaves, they measure the height of ocean water, help create weather maps, predict the formation of hurricanes and monitor ocean levels.

To create a map like this, we needed a comprehensive knowledge of the bathymetry and topography of the seabed. Here you can see the relief features of the earth's surface under water, and on the graph you can find out the depth of the world's oceans in meters.

Village Panshino — amazing place on the right bank of the Volga, about forty kilometers south of Syzran.

Administratively, this region of the Right Bank is included in the Ulyanovsk region. However, it turned out that, in addition to local residents, Syzran residents are engaged in fishing here, so it would be unfair to exclude this area of ​​the reservoir from among favorite places fishing for residents of the Samara region.

Having driven south from Syzran along the highway leading to Vozrozhdenie to Kalinovka, you should turn left, pass the crossing and move east a few more kilometers along the ridge of a high hill. Soon a picture, colorful in scale and amazing in beauty, opens up: on the right in the hollow is an abandoned garden, on the left is a deep ravine, covered with bushes and separate standing trees, and right on the hillside is the small village of Panshino, behind which stretches an endless expanse of water about ten kilometers to the left bank.

An extensive network of islands opposite the village and downstream divides the reservoir into several branches, forming channels and bays.

The coast here is high and hilly. There is a cliff up to three meters high near the water itself. The bottom is marshy, muddy, interspersed with sharp gravel and shells, and gently slopes into the depths. On the shore opposite the village and to the left are several improvised parking lots for the vehicles in which the fishermen arrived. Sometimes there are 30 - 40 cars and motorcycles with Penza, Samara, Ulyanovsk and Saratov license plates.

It is difficult to remain without fish in Panshino. The place is so “cool” that almost at any time of the year and in any weather you can count on a rich catch. The main thing is to drive here and get back, which is not easy in rainy or snowy weather. And the weather here sometimes changes instantly. You arrive in the morning - the sun is shining brightly, the water is calm, there is almost no wind, there is no sign of bad weather. And suddenly at noon a black cloud emerges from behind the hill and hangs menacingly over the water. The Volga darkens before our eyes, boils, and now a squall of rain and waves hits the boat!

And twenty minutes later the thunderstorm passed, and the sun shone again, reflected in thousands of droplets on the grass and trees. Everything is wonderful, but the ground is so wet that none of those who arrived by car can get up the mountain on wheels. The most impatient ones have already gone to the village to get a tractor...

In summer, the main catch of fishermen in Panshino is bream.

In Panshino, in the spring, roach fishes well on a fishing rod from a boat, and you can often catch chub and ide. Local fishermen set nets for catfish and pike. They also catch catfish using the “kwok”. It must be said that for some reason the fish caught here are one and a half times larger in size than in other places!

And one more thing. Motorboat owners know this area as a place where reverse current rivers. This phenomenon is explained by hydrodynamic reasons: complex system The islands and the bottom topography force the water flow to turn back in some places, towards the main current. When there is no bite anywhere, you will always catch it on the “return”, many believe.

A few kilometers upstream from Panshino there is another catching place.

now it looks like this...

They call him " monastery"due to the ruins of an old chapel on the shore, clearly visible from the water. Another landmark can be the huge barge of the berth for bulk carriers, once transporting waste from the shale production located nearby Kashpirsky mine. (the barge has already been cut into scrap metal)

This “bream” place, quite far from the fairway, has a depth of up to 20 meters at a distance of only one hundred meters from the shore. Current at " monastery" noticeably stronger than Panshino, since the reservoir narrows in this place. It often happens that the bream does not take well Panshino, here he is caught successfully.

An extensive section of the Saratov reservoir in the region Panshino, indented by numerous islands, with large number shallow water zones, is famous place for lovers of winter fishing. Their main prey are perch, pike, roach, and silver bream.

To catch large perch, anglers go to the middle of the reservoir. Knowledge of the bottom topography allows them to search for “humpback whales” not at random, but along the boundaries of underwater ridges, which extend parallel to each other for several hundred meters. Connoisseurs catch perch with a spinner and a jig without bloodworms from a depth of 2.5-3 meters. This type of fishing is truly sporty and exciting! Agree, not everyone is able to walk five or six kilometers through the snow from the shore to the site, drill several dozen holes in a day and then return back with a heavier backpack.

Fishermen older in winter period Usually they settle closer to the shore - they catch roach and silver bream. They are immediately easy to distinguish from others by their polyethylene tents that protect from wind and cold. “Perch fishermen” don’t use tents, they need to move, drill, otherwise you won’t catch them.

Come here any weekend from December to March - you will see how many winter fishing enthusiasts gather in Panshino!

Bottom topography (location of holes and “cool” fishing spots) is a key factor influencing the success of fishing. He has more weight compared to the quality of gear, fishing technique, choice of bait, bait and even experience. Full equipment and expensive ammunition will not give anything when casting in a remote, poor place where the fish are absent or bite weakly. A map of depths, holes and fishing spots provides knowledge of the topography of the bottom of reservoirs. The depth map visualizes the features of the underwater landscape and its key characteristics. The tool helps predict promising fishing zones that promise a significant catch, read the underwater landscape, and helps calculate depth change lines and potentially catchy points. Fishing card useful when fishing from the shore and from a boat.

The card functionality provides more information for any type of fishing. The map is useful for fishermen, regardless of their experience, thanks to a large list of parameters necessary for successful fishing. The system is multi-level, based on Yandex.Maps information. The database includes a compilation of three cartographic resources, which guarantees the accuracy of the calculation results with small errors. The program displays depth indicators in navigable rivers, seas and oceans, calculates potential holes where bites are more frequent, and the fishing spots of all site participants. You can leave personal “beacons” from successful places where the catch was impressive, so that if necessary, you can return to a familiar point next time.

Displayed data: depths, holes (including Navionics data), fishing spots added by users, exact coordinates of the desired location. Fishermen have access to zoom and search options, select the desired map layer, and calculate the current location. Presented full screen mode. The card interface is intuitive - balanced functionality, everything necessary buttons at hand, nothing superfluous. It’s easy to use, regardless of fishing experience – the data on the depths of rivers and reservoirs is comprehensive.

Identification of holes, international depths and fishing spots. When you click on the corresponding buttons, you will see the holes recorded by the program that are available in the body of interest. Natural depressions from 3 m are displayed, the starting value depends on the bottom topography of a given river, sea, ocean and can be reduced. Please note: fishing holes are located outside the fairway area. The service does not determine the length, extent, direction of depressions, etc. additional characteristics landscape. Its functionality is focused solely on calculating the depths of a certain zone and their location. Using the presented platform, you can find out the data of rivers, oceans and seas of any region or region.

Visually visualizes the landscape, showing the user the latitude and longitude of the location/point he has specified. After clicking on the desired location, the program provides a detailed geographical summary. The function will help you get directions without geographical names, the coordinates calculated by the fishing map are sufficient. The location determination option is universal - the information can be used in an echo sounder, GPS device, navigator, chartplotter. The program helps you navigate the terrain thanks to a convenient zoom function and accurate calculation of distances between any number of points.

A sailing guide is not only a map for sailors and rivermen, it is a rich storehouse of information for treasure hunters and local historians. Looking at the map, you can see changes in the river bed, coastal settlements and a lot of other interesting information.
