|dc.description.abstract||1. The data examined consist of hydrographic sections in the western
Irminger Sea and serial observations at Ocean Weather Station
Alpha (Station A). The sections were worked in the years 1959 and 1961
-1964, and at station A the data were collected during 5 periods of
observation in the years 1954-1963.
2. The sections as well as the data from Station A are used to give
the characteristics and extent of different water masses. The occurence
of possible annual variations is also examined.
3. South of the Denmark Strait it is difficult to characterize Polar
water by means of temperature and salinity, but 34.50 ‰ seems to be
the upper limit of its salinity.
4. The intermediate water in the Irminger Sea is found at about 1 000
m depth, and T-S relations for the data from Station A show that the
minimum temperature and salinity of intermediate water are 3.5° C and
5. In the Denmark Strait Arctic Intermediate water exhibits temperatures
near, or below, 1°C, and salinities chiefly below 34.90 ‰. This
water mass seems to be the main source of the bottom water in the
6. The amount of Atlantic water which is carried to the Irminger
Sea by the Irminger Current, varies from year to year. These variations
are studied in the western branch of the Irminger Current and at Station
A. In 1954-1956 only small amounts of Atlantic water were observed,
but the Atlantic inflow increased until 1959-1960. During the years
after 1961 the amount decreased again.
7. At Station A the wind conditions are examined, and there is a
close relationship between the accumulated wind and the mean salinity
in the different periods of observation.||
