permanent modification (Mangalia, Midia, Gura Portit ¸ei, Sf. Gheorghe, Sulina) and
of the seacoast lakes was continued with the purpose of assuring some activities
organised by the Navy and some ministrys. The hydrographic piece of work were
extended to the boundary of the continental plateau, and hydrological piece of work
extended from west basin of the Black Sea, in the international liability boundaries
of our country. The analysis consisted of: the determination of planimetric base
of canvass in the zone Chituc – Gura Portitei; the hydrographic survey of the coastal
strip on a breadth of 100–150 m from the water surface, in the Constanta – Gura
Portitei area, at the scale 1:10,000; the hydrographic survey in the Tuzla – Eforie
Sud area, between 5 and 12 m, at the scale 1:10,000; the hydrographic survey in the
Eforie Sud-Gura Portitei area, from the sea surface to the isobath of 12 m, at
the scale 1:10,000; the hydrographic survey in the Midia – Gura Portitei area,
from the isobath of 8 m until the boundary of the range of the radio navigation
stations, at the scale 1:50,000; hydrographic survey in the Neptun – Comorova area,
from the depth of 5 m to the coast; hydrographic survey in the Midia – Gura Portitei
area; the production of the Romanian Black Sea charts, first edition, at different
scales. The Romanian Military Topographic Directorate helped The Maritime
Hydrographic Directorate with the photographing and reducing to scale in Mercator
projection of the principal cartographic materials for obtaining the originals of the
maritime charts. Those were drawn with the topographic pen by the cartographers
from the Maritime Hydrographic Directorate.
From 1966 The Maritime Hydrographic Directorate became the Romanian
government representative, as a State Member of IALA/AISM.
In this period the Maritime Hydrographic Directorate executed actions of great
diversity for the benefit of Romanian military and civilian ships, to ensure the safety
of navigation in the area of responsibility of Romania, of which the most important
were: hydrographic and oceanographic campaigns between 1957–1970 and
1973–1982; editing The Romanian Black Sea Pilot, and Notices for mariners;
installation of the speed base from Tuzla (1957); installing the unlit signals at Chituc
and Zaton (1958); electrifying the lighthouses Tuzla (1957) and Midia (1958),
construction and commissioning of Constanta’s lighthouse (1960); construction and
commissioning a new lighthouse from Sfantu Gheorghe (1968) (Moroianu 2012).
Last but not least we offer a briefly reviews of the hydrographic survey campaigns, with the summary indication of the action areas in which oceanographic
systematic survey were carried out, on hydrological standardized profile, seasonally
repeated four times, each year or multidiural fixed stations, researches in which
Romanian hydrographers directly participated actively and permanently, as follows
(Selariu 2011):
(a) 1959–1960, stage in which, through considerable effort has been made a
valuable joint action of hydrology and marine hydrography in territorial waters,
with hydrological research and off the continental shelf, on two profiles of
approximately 100 nautical miles each (East Gura Portit ¸ei and East Mangalia);
(b) 1961–1969, the stage in witch has implemented cooperation joint plan system
