The normative legal basis in the sphere of ecological
safety for the seas of the Arctic zone is analyzed. The necessity to develop
the complex technology for search and identification of submarine potentially
dangerous objects is shown. The main statements and principal solutions
intended to develop the above technology are formulated.

Limitation
for Possible Values of Harmonic Parameters of Tides. Y. N. Zhukov – Navigation and Hydrography. – 2014. – No. 38. – Ð. 36–43.
In the theory of the harmonic analysis of tides, there
is no definition of any limitation for harmonic constants values for various
points located within one water area. It is shown that such limitations do
exist. They are revealed due to the existence of synchronization of the tidal
variations for the water area space.
Key words: tides, harmonic constants.
Algorithm of
the Automated Construction of the Kronrod-Reeb Tree. Y. N. Zhukov – Navigation and Hydrography. – 2014. – No. 38. – Ð. 44–50.
The traditional algorithms for constructing the Kronrod-Reeb tree for the relief are based on employment of
the isohypses constructed for the differentiable
relief surface. The algorithm for constructing the Kronrod-Reeb
tree using the discrete description of the relief in the form of Morse-Smale cells is presented.
Key words: the surface of relief, topology, the
Kronrod-Reeb tree, Morse-Smale cells.
Preparation

Navigation Charts. L.
D. Yastrebov, A. G. Karmanov
– Navigation and Hydrography. – 2014. – No. 38. – Ð. 50–56.
The practical necessity for the automatic construction
of the isobaths is shown. The problems of using the sections of the surface as
isobaths are considered. The suggested algorithm that enables to construct
automatically the isobaths on the electronic navigation charts is described.
This algorithm can also be used to construct the isobaths using the depth
measurement data, taking the set variations in depth and other parameters into
account.

surface, hydrography, navigation charts, survey data, S-57 Standard, algorithm,
interpolation.
Some Aspects
of Sonar Search Technology for Bottom Objects. N. A. Nesterov – Navigation and
Hydrography. – 2014. – No. 38. – Ð.
57–65.
Some aspects of sonar search technology for bottom
objects are considered. It is noted that modern sonar systems are effective
means used for search and examination of bottom objects, both silted and
located in the soil. The effectiveness of search operations is largely
determined by the technology of using the equipment. An important role is also
played by the detailed information about the characteristics of objects and physico-geographical conditions of the search area. The
article is of a practical nature and can be used when solving the tasks of
planning and carrying out the operations.
Key words: side scan sonar, multibeam echosounder,
tow fish, sonar survey, bottom profiler.
Evaluation
of Climate Severity Degree of Northern Eurasia in Winter Period. S. I. Mastryukov, N. V. Chervyakova – Navigation and Hydrography. – 2014. – No. 38. – Ð. 66–73.
New climatic indexes that can be used to evaluate the
influence of cold on man are proposed. The first of them is the absolute
minimum of wind chill equivalent temperature that is important for adequate
selection of means of individual protection against the cold. The second is the
time period with wind chill temperature below the set limits that is important
for technical-economical substantiation of effectiveness of projects for the
Far North development. The calculation of the equivalent temperature has been
carried out using the new formula, the contour maps of
the new indexes have been drawn using the data of the coastal meteorological
observations in the northern part of Eurasia for 2007 – 2014.
Key words: equivalent temperature, wind chill of man,
safety of man, health, biometeorology, development of shelf of the Arctic seas.

evaluate the wind chill of man are reviewed. The results of comparative
evaluation of some indexes of wind chill are presented. The disagreement of the
national and foreign methods used to calculate the wind chill equivalent

recommended to carry out the regionalization of the Russia territories based on
the biometeorological and technical-economical
indexes connected with the influence of cold on man.

of temperature, wind chill of man, safety of man, health, biometeorology,
