A INTRODUCTION 
The METEOR cruise No, 20 led to the sea area between 
the Faeroes and Iceland, Leg 1 (METEOR cruise No, 20a) 
had been intended for oceanographical investigations 
off SE Iceland. The eruise was carried out between 
21 April and 25 May 1970 (Hamburg-Iceland-Hamburg), 
At the outer edge of the SE Icelandic shelf (water- 
depth abt. 150 m) and in the area of the Iceland-Faeroes 
Ridge's Atlantic flank (waterdepth abt 500 m) 36 in- 
struments had been moored in two equilateral triangles 
for almost 20 days, Besides, two permanent stations of 
several days had been occupied within these triangles, 
At the beginning of the work, a quasi-synoptic hydro- 
graphic survey of the adjacent areas was made (see 
figs 1 and 2). Table I shows the list of all stations, 
The variability in time of temperature, salinity, and 
dxygen contents, as well as the variability in space 
and time of temperature, current, and sea level were 
to be measured, The main objectives are: 
Current measurements as repetition of the 
measurements at stations B1/B2 during 
OVERFLOW 1960 (station 11,3 of the southern 
triangle); 
Investigations on the structure and dynamics 
of the polar front in the boundary area 
between the cold east Icelandic water masses 
and. the warm water masses of the Atlantic; 
Measurements in order to study the problems 
of energy transformation and -dissipation at 
a steep continental slope, especially in 
connection with the shelf waves, 
This volume contains the data of the METEOR cruise 
No, 20a, They are presented in graphs and tables,
