EXPLANATION OF TABLE 3 



This table includes the field data relative to all planktou eoUec- 

 tious made from 1913 to 1915 inclusive for quantitative investigations. 



First column. — Numbers under which the collections are accessioned; they 

 are arranged in chronological order irrespective of the nature of the haul. The 

 letter L or B relates either to the left or right haul of the duplicate ones made 

 with the "serial closing apparatus" (see p. 209). 



Second column. — Apparatus used in making the collections; K.B. refers to 

 the Kofoid water bottle (see p. 212); S.OOO refers to the serial closing api.aratus 

 (see p. 209), the nets of which are equivalent in size and filtering capacity to 

 the K.OOO; K.OOO, and all remaining symbols refer to nets of the mesh indicated, 

 and having the dimensions given in Appendix 1, page 201 of our former (191.5) 

 report. 



Third and fonrth columns. — Time of day and duration of haul entered to the 

 nearest minute. 



Fifth column. — Section; for explanation see page 217. 



Si.rth and seventh columns. — Latitude and longitude entered to the nearest 

 O'.i when the error was within OfS, and to the nearest minute when the error 

 was larger; see explanation to table 1, page 218. 



Eighth column. — Depth of haul entered to the nearest meter above and to the 

 nearest five below 200 meters; for error see former report (191.5, p. 20). 



Ninth column. — Numbers indicating water samples taken in connection with 

 haul (see table 1). Since 1912 water samples have frequently been taken at 

 the beginning and end of each haul; when only one was obtained its entry in 

 the left or right hand part of the column means that it was taken nearest the 

 beginning or end of the haul. 



Tenth column. — Miscellaneous remarks relative to hauls; unless otherwise 

 stated the ajijiaratus worked properly so far as known.
