En 1922, le même programme a été suivi en ce qui concerne les croisières de 

 la "Tanche" et du "Pourquoi Pas?" ainsi que les tournées périodiques des canon- 

 nières. Ce programme est actuellement encore en cours d'exécution. De plus une 

 mission spéciale de recherches océanographiques a été accomplie sur le Barre de Vue 

 Neuve par le croiseur "Garriopée" ayant à son bord le Dr. le Danois. 



Le résultat des croisières de 1921 fera l'objet d'une partie du rapport du 

 Comité du Plateau Continental Atlantique. 



Great Britain. England, The research vessel "George Bligh" was laid up in 

 the interests of public economy during December and January. During the period 

 covered by the present British report 21 cruises were made in the North Sea and the 

 eastern part of the English Channel. 



Scotland. From July 1921 to February 1922 the research vessel "Goldseeker" 

 carried out a series of eight cruises lasting about three weeks each, In February 

 this vessel was dismantled in preparation for the fitting out and commissioning 

 of the new research vessel the "Explorer." Owing to the industrial position great 

 delay was experienced in getting the ship ready for sea and her first cruise was 

 not started until July 1922. 



In the first cruise of the "Goldseeker" trawling experiments were made in 

 the Moray Firth and off the Aberdeenshire coast. In August, however, in view of 

 the failure of the Scottish drift-net summer herring fishing, the area between Aber- 

 deen and Shetland was surveyed to ascertain the prevailing hydrographie and 

 planktonic conditions. A second survey of this area was completed in September 

 as well as a further trawling survey of the Aberdeenshire grounds. The third series 

 of trawling experiments was carried out off the Lincolnshire coast with a view to 

 transplanting Black Soles from that area to the Scottish coast. Whilst the season 

 was perhaps somewhat late for such experiments, the exceptionally rough weather 

 experienced both during the trawling operations and on the passage north interfered 

 greatly with the proper conduct of the experiments and only thirty-nine soles were 

 brought alive to the Firth of Forth and liberated there. During the latter part of 

 November, in December and in February, the Moray Firth and Aberdeenshire 

 grounds were again surveyed. 



In the period under review, the observations made with the commercial 



otter trawl were distributed as follows :
