Current-measurements have been carried out from the lightships "Schultz's 

 Grund" and "Skagens Rev" during one month in the summer 1922. 



Finland. Preparatory works were agreed upon for the re-organisation of 

 the fishery statistics. 



1921. July. Res. IV. A short cruise in the Bothnie and in the Gulf of Finland 

 was made in November 1921. A cruise of 52 stations in the Gulf of Finland, northern 

 Baltic and the Bothnie was carried out from 26 Mai to 8 June. 



1921. July. Res. V. Observations of salinity, temperature and currents on 

 10 lightships in time with water without ice and of salinity and temperature in the 

 whole year at 27 coastal points are made in the surface and at different depths 

 three times daily, daily, six times and three times in the month. 



1921. July. Res. VI. From 18 — 29 July continuous observations of currents, 

 salinity, temperature, oxygen, carbonic acid, alkaHnity, hydrogen-ion, in different 

 depths were carried out from the lightship Storbrotten in the Southern Quark and 

 from the motorship "Aurelia" at anchor east from Aland (near Jungfruskär). At 

 the same time provisional supplementary mareographs were working at Jungfru- 

 skär (east) and Hellman (west from Aland). On Jungfruskär were made observations 

 of evaporation and insolation and other meteorological elements. From S/S "Nauti- 

 lus" continuous currentmeasurements and traditional thalassological determinations 

 were carried out at different stations and different depths (esp. 3 days in the deep 

 channel of the southern Quark and three days in the deep channel of Skiftet east 

 from Aland). 



1921. July. Res. VII. Observations from the stations named in Res. V. will 

 be sent for publication. 



Sweden. Svenska Hydrografisk Biologiska Kommissionen has from July 

 1921 to July 1922 executed: 



3 expeditions in the Southern Baltic in order to study the hydrographie 

 conditions of this part of the Sea, (two expeditions in August — September 1921 

 and one in March — April 1922) and their influence on fishlife. The hydrographie 

 as well as the biological investigation has been carried out in every detail according 

 to modern principles. New rich fishing grounds have been discovered South of 

 Skane and East of Bornholm. 



One expedition in common with the Finlandish Thalassological Institute in 

 the Aland Sea in order to study the interchange of waters (by current-measurements 

 and hydrographie observations of different depths) between the Baltic proper and 

 the Bothnian Sea (July 1922). 



A study of the hydrographie qualification of the different waterlayers in 

 Skagerak, Kattegat and the Baltic by a series of hydrographie deepsoundings in 

 the deepest part of these Seas (in September, April and July).
