D. Additional Nansen Cast Information. 



1 . Cast No. Individual Nansen bottle casts are numbered by Roman 

 numerals . 



2. Wire Angle. The angle between the oceanographic wire and the 

 vertical, measured by an inclinometer, is recorded in whole degrees. 



3. Nansen Bottles. The number of Nansen bottles employed on a Nansen 

 cast . 



4. Protected Thermometers. Used - the number of protected reversing 

 thermometers employed on the designated Nansen cast . Accepted - the number 

 of temperatures from protected thermometers actually accepted, individually or 

 for an average . 



5. Unprotected Thermometers. Used - the number of unprotected reversing 

 thermometers employed on the designated Nansen cast . Accepted - the number 

 of unprotected thermometers actually accepted based on the difference between 

 the computed thermometric depth and the accepted depth (i .e., when the dif- 

 ference is within - .5% of the accepted depth). Accepted depths are determined 

 by L - Z curve methods described in publication H .O . 607.
