Today, the Pacific Fleet (Pacific Fleet) celebrates the 164th anniversary of the formation of the Pacific Fleet’s hydrographic service.

At present, the hydrographic service of the Pacific Fleet includes more than 40 ships and boats of various classes and continues to be replenished with ships of new projects, while simultaneously performing a huge amount of work in the World Ocean. And this geography is quite extensive: from the Chukchi Sea to the South China Sea.

This year, in the area of ​​responsibility of the Pacific Fleet, hydrographic vessels (HS) have done colossal research work.

The newest GS “Alexander Rogotsky” conducted a two-month research expedition in the area of ​​the Kuril Islands. Military hydrographers conducted a comprehensive study of the coastal zone of the islands and the hydrology of the sea. Collecting, updating and entering data into new navigation maps.

GS “Pegas” also took part in similar research activities in the Kuril Islands region.

The work was carried out by specialists using the latest equipment at the ship’s disposal: multi-beam echo sounders, an open sea tide gauge, sound speed meters.

For more than a month in the area of ​​the central Kuril Islands, the study of currents, sea hydrology and weather conditions was carried out by the GS “Vice-Admiral Vorontsov” under the command of Igor Sadov.

In addition, the specialists of the Pacific Fleet’s hydrographic service performed a number of hydrographic works in Provideniya Bay and in the area of ​​Cape Chaplin of the Bering Sea.

The crew of the hydrographic vessel GS “Sever” carried out measures to study the hydrology of the sea, clarify the bottom topography, and also made a topographic survey of the coastline. The data obtained made it possible to make corrections in navigation charts, manuals and aids for swimming in high latitudes.

Along with northern explorations, the southern Pacific has become the theater of navigation for hydrographers this year.

This year the hydrographic vessel of the Pacific Fleet “Marshal Gelovani” made a long voyage to the shores of Antarctica. The voyage, which was supported by the Russian Geographical Society, lasted more than three months and was dedicated to the 200th anniversary of the discovery of Antarctica and the 250th anniversary of the birth of Admiral Ivan Kruzenshtern. During the passage by sea and in the Antarctic region, the Pacific Fleet specialists carried out depth measurements, conducted a number of accompanying studies.

For the first time in 30 years, at the supposed point of the Earth’s South Magnetic Pole, the Marshal Gelovani hydrographic vessel carried out measurements to determine the exact coordinates of the pole, and investigated the hydrology of the sea in this area.

Over the past two years, the Pacific Fleet hydrographers have carried out about 10 research services in various regions of the World Ocean. At present, a constant survey of the coast of the entire Far East is underway.

For reference:

The history of the Pacific Fleet’s hydrographic service begins from the century before last, when by the Decree of Emperor Alexander II of October 31, 1856, the hydrographic part was introduced into the staff of the Siberian Flotilla Administration. She was entrusted with the management of the lighthouse service, the pilotage unit and ensuring the safety of navigation of the ships of the flotilla.

In connection with the rapid growth of the importance of Vladivostok as a port and center of a developing region with its advantageous geographical position, a separate survey of the Eastern Ocean was created in 1880, the task of which was a comprehensive hydrographic study of bays, bays and anchorage places most frequently visited by ships.

Outstanding Russian naval leaders and scientists, General of the Hydrographic Corps Mikhail Zhdanko, and Vice Admiral Stepan Makarov, Commander of the Pacific Squadron, made a great contribution to the study of the northwestern part of the Pacific Ocean.

In the harsh years of the Russo-Japanese and the Great Patriotic War, hydrography carried out measures to deploy navigation aids to the fleet, coordinate the laying of minefields on the approaches to Vladivostok, Petropavlovsk-Kamchatsky and other cities. The military pilot service was deployed.

In the second half of the 20th century, along with ensuring the daily activities of the fleet and trawling hazardous areas from mines, hydrographic studies of the seas were continued, which was due to the replenishment of the fleet with research vessels with a large navigation autonomy.

The fleet’s lighthouse service was actively developing. To date, the Pacific Fleet’s hydrographic service has 93 lighthouses with geography ranging from the northern latitudes of Anadyr and Magadan to southern Primorye.
