INTERNATIONAL ASPECTS OF OCEANOGRAPHY 



used for the study of the physical and chemical 

 properties and the movements of the water masses — 

 for example, west of the Galapagos Islands, between 

 the equator and 10° of north latitude, to 140° west 

 longitude, there is no information except at one 

 station on the equator which was occupied for sub- 

 surface temperature. There are no data on the 

 area between 10° and 20° north latitude and 100° 

 and 130° west longitude. In the south Pacific there 

 are large areas within which there are no available 

 observations. In the west Pacific west of 170° 

 west longitude over to the area of operation of the 

 Japanese there are very few observations. 



In the Indian Ocean, between the areas recently 

 worked by the Mabahiss and the Dana in its 

 northern part, and the areas investigated by Dis- 

 covery I and Discovery II and Norwegia around 

 Antarctica, and between lines from Antarctica to 

 the Cape of Good Hope and from Antarctica to 

 southern Australia, there are very few observations. 

 There are many areas 10 degrees of latitude and 10 

 degrees of longitude on a .side for which there is not 

 a single observation. 



Until more oceanographic observations have been 

 made in these areas it will not be possible to solve 



numerous important oceanographic problems. For 

 example, for the strip, between 10°S and 20°N 

 latitude, across the Pacific Ocean that includes 

 the North Equatorial Current, the Equatorial 

 Counter Current, and the South Equatorial Current 

 there are very few observations. The Carnegie 

 in its cruises in the Pacific crossed this belt along 

 three lines and a few observations were made by the 

 Dana. Otherwise, except records of temperature 

 and one fine of serial sections of temperature and 

 salinity, reliable data are confined to the east and 

 west ends of the belt. 



To make more extended comments seems un- 

 necessary. 



Professors Sverdrup, Helland-Hansen, and Wiist 

 have put on the charts prepared by them the num- 

 bers for the different stations, as well as abbrevi- 

 ations. It would have been preferable to have done 

 this for the other stations instead of merely put- 

 ting down the abbreviations for the names of the 

 vessels from which the observations and collections 

 were made, but with the references to sources of 

 data additional information on the stations can be 

 procured by those who desire it.
