COPEPODS OF LAST CRUISE OF CARNEGIE 



Station- 10 

 July 30, 1928: 59° 19' N. 34° 15' W; bottom depth. 3031 m; 8 species 



Depth of tow, m 

 Temperature, °C 

 Salinity, o/oo 



Anomalocera patersonii . 

 Calanus finmarchicus. . . 



Euchaeta marina 



Microsetella norvegica. . 



Oithona siinilis 



spinirostris 



Oithonina nana 



Pseudocalanus minutus. 



The 8 species here recorded constitute the smallest yield 

 for any regular station at which all three tows were taken, 

 and with only one exception they were all confined to a single 

 depth. Although the temperature at the 100-meter level was 



but 6?6, that tow as well as the other two contained hundreds 

 of nauplii and metanauplii, of which those in the 100-meter 

 tow must have been negatively phototropic. This is the second 

 of the two Atlantic records for Anomalocera patersonii. 



Station 11 

 August 1, 1928; 58° 12' X, 35° 51' W; bottom depth, 2633 m; 10 species 



Depth of tow, m 

 Temperature, °C 

 Salinity, o/oo 



Calanus finmarchicus 



Euchirella rostrata 



Heterorhabdus norvegicus. 



Metridia lucens 



Microsetella norvegica. . . . 



Oithona similis 



spinirostris 



Oithonina nana 



Pareuchaeta tonsa. . . . 

 Scolecithricella minor. 



Eight of the 10 species were confined to the 50-meter tow, 

 only 2 appearing at the surface. These tows were taken in a 

 \ery dense fog, which may explain why some of the Calanus 

 finmarchicus did not come to the surface. This is the only 



record for Heterorhabdus norvegicus and the only Atlantic 

 record for Metridia lucens, and the first of two for the Carnegie 

 for this ocean {or Pareuchaeta tonsa; the second was made at 

 station 12, immediately following.
