HYDROGRAPHICAL INVESTIGATIONS 215 



investigations. Scotland makes use of the Scottish 

 Fishery Board station at Aberdeen for the 

 biological work, and a laboratory at University 

 College, Dundee, for the hydrographical investiga- 

 tions. The direction of the researches is exercised 

 in Scotland by Professor D'Arcy Thompson, and 

 in England by Dr Allen and Mr W. Garstang. 



Each State investigates a particular portion of 

 the whole sea area. The investigations are some- 

 times referred to as if they were carried out in 

 the North Sea only. The area in question is in 

 reality very much wider than this. Britain has 

 charge of the eastern part of the North Sea, the 

 Atlantic as far north as the Faeroe Islands, and to 

 the west of the Outer Hebrides, and the English 

 Channel. Germany investigates the western 

 portion of the North Sea, and the Baltic Sea off the 

 German coast. Russia has the rest of the Baltic 

 (except the Gulf of Bothnia, which is investigated 

 by Finland), and the Arctic Ocean to the north of 

 the White Sea. Denmark has the Cattegat, the 

 Belts, and the Sound, and the Faeroe- Iceland 

 channel. Norway and Sweden between them 

 work the Skagerack and the seas off the Baltic 

 coast of Scandinavia, and Norway also explores an 

 extensive area extending fron Iceland and Jan 

 Mayen to the opposite Norwegian coast. 1 Each 

 vessel makes quarterly cruises along certain lines
