A number of data-sets have been acquired through other organisations and from individual 
scientists. 
1) The German Oceanographic Data Centre (DOD, Hamburg) contributed with a 
substantial number of profiles obtained in the Atlantic Ocean aboard German research 
vessels, 
2) The Alfred-Wegener-Institute (Bremerhaven, Germany) shared with us a collection of the 
data collected in the northern and southern polar regions, 
3) The Arctic and Antarctic Research Institute AARI (Saint Petersburg, Russia) provided a 
unique data set from the western Weddell Sea (Weddell Ice Station Data), 
4) The French Oceanographic Data Centre (IFREMER, Brest) contributed a number of 
French oceanographic cruises occupied in the Atlantic Ocean. 
Among other data-sets, obtained in the earlier data-empty regions we mention a data-set 
from the Pacific sector of the Southern Ocean (Lamont Doherty Earth Laboratory, courtesy of 
S.Jacobs) 
The total number of hydrographic profiles included in our composite data-set is 1,059,535
