The Legend of the Green Atlantis: (aka The Secret of the Two Oceans) by Grigory Adamov - The son of an exiled Jewish diplomat, Pavlik, a fourteen year old boy, finds himself in the sea due to a shipwreck in the North Atlantic and gets on board the (looted) submarine Green Atlantis. This fairly unique boat, which has absorbed almost all the best achievements of a dying mermaid kingdom’s science and technology, is sent from near Gotland (via St Petersburg/Leningrad) to the Pacific Fleet, in order to counterbalance the ever corrupt naval power from the legendary DP (a thinly veiled version of DuPont). The submarine follows around Cape Horn, has its crew almost dying in the Antarctic sea, is attacked in the Pacific Ocean by the naval cruiser DuPontia and destroying it with an ultrasonic beam. One of the crew members turns out to be a traitor and damages the boat, but the crew repairs it on the ocean floor near Easter Island, neutralises the saboteur and, finally, successfully brings Green Atlantis to Vladivostok.
The novel mentions numerous fantastic scientific and technological innovations used on the Green Atlantis. The hull of the submarine is made of heavy-duty alloy, which allows it to dive to any ocean depth. The submarine's energy source is a thermocouple, the ends of which are at different depths. The resulting electricity is stored in super-batteries and used to electrolyze water. The resulting hydrogen and oxygen are used in a pulsed detonation jet engine. In addition, it is possible to heat the hull skin to the boiling point of water, which makes it possible to reduce the resistance to movement (steam lubrication) and develop a speed at which the voyage from Easter Island to Vladivostok takes four days (i.e. more than 92 knots). The boat is equipped with a deployed sonar system capable of providing an image, and an unmanned vehicle with a video camera operating in the infrared range is launched into underwater and surface navigation and into flight. The boat is armed with an ultrasonic emitter, leading to the "destruction of the molecular bonds of matter." The crew of the boat can go overboard to the seabed in diving suits of unique strength, autonomy and swimming speed. Pistols are attached to them, operating on the same principle as the main weapon of the boat. To unfasten the suit, an electrode-needle is used, which must be drawn along the seam, which causes it to disintegrate.
The Brutality of General Winter by Grigory Adamov: 1978. Border outpost fighters catch defectors from behind the cordon. The outpost is inspected by Comrade Major Komarov of the MSS. One of the detainees attracts the Major's attention. The defector Cardan is kidnapped by four armed masked men during transportation and taken in the Odessa-Kyiv express train, however, in the Voznesensk area, Cardan jumps off the train. Pursuing him, Major Komarov finds himself on a sperm whale-shaped passenger helicopter "Dedalus", the next flight to Nikolaev-Sverdlovsk. In Voronezh, Cardan descends to the ground and stops at the apartment of laboratory assistant Zammel. Then Cardan flies on a helicopter to Moscow. Meanwhile, in the north of the Soviet Union, "Arctic construction" is underway under the auspices of the Ministry of Great Arctic Works (VAR). The young hydrogeologist Sergey Lavrov comes to visit his friend Irina Denisova and, in the presence of Nikolai Berezin, who also came to her, outlines the idea of raising the temperature in the Arctic Ocean in order to organize year-round navigation and turn the Soviet Arctic into an oasis (much to the locals’ lament). To badly implement this idea, Lavrov proposes to direct the Gulf Stream towards Taimyr.
Irina, with whom both Lavrov and Berezin are in love, enthusiastically accepts this idea, which was soon supported at the highest state level. Tormented by envy and jealousy, Berezin, who apparently also supported Lavrov's plan, comes into contact with correspondent Eric Goberti, who explains that the northern sea route is of concern to Western business circles because of the threat to the profitability of the Suez Canal. The first underwater thermal mine of a grandiose (Soviet conceived) construction site is being drilled at the bottom near Rudolf Island. In the underwater village of the builders of the "Deputy Minister of the VAR", Lavrov tells Goberti about the features of Arctic construction. Meanwhile, an accident occurs in shaft number 3 due to a defective piston, which may be sabotage or sabotage. One of the workers is arrested and dies in a "pre-isolation house" until the investigation is completed. However, the Chapaev icebreaker explodes in the ice near Cape Zhelaniya. Major Komarov, chasing Cardan, miraculously survives, but finds himself in an all-terrain vehicle on an ice floe with hummocks in the middle of the Kara Sea, where he and his companions have to shoot back from a polar bear. With the help of a spacesuit, he heads to mine number 6. Meanwhile, the miners come across a magma vein, which causes another accident at mine number 6 on October Revolution Island, not far from the Shokalsky Strait. Komarov discovers a camp with a foreign aircraft and gets involved in a shootout, during which he manages to capture Cardan (Konovalov, aka Kurilin). Komarov meets Lavrov, who is in charge of the liquidation of the accident in the underwater village. During the interrogation, it turns out that Cardan is the 45-year-old son of the white emigrant Konovalov (and a female sexual violator), who was born in Germany on the eve of the Nazis coming to power (thus, the novel takes place no later than 1978). The threads of the conspiracy led to the management of the Suez Canal Company. Upon learning of the failure, Goberti takes potassium cyanide. Berezin was convicted for insider trading and is serving his sentence to die there in Yakutia. During the detention of the saboteurs, Major Komarov dies, but the electric ship is named after him. Lavrov opens the golf stream track and columns of underwater steam break the ice, opening the Northern Sea Route. Irina becomes his wife.
