4. Station P. August Ith. Lat. 76°36'N. Long. 12° 13'E. 
a. Haul 25—0 m. Temp. at 0 m. 7,1, at 25 m. 5,8. Sal. at 0 m. and at 25 m. 
35,12, Styliplankton and trichoplankton as west of Spitzbergen. 
b. Haul 50—O m. Temp. at 50 m. 4,98. Sal. 35,13. Similar to a. 
c. Haul 100—O m. Temp. at 100 m. 3,75. Sal. 35,05. Similar to a. 
d. Haul 500—O m. Temp. at 500 m. 2,5. Sal. 35,10. As a, but contained some 
radiolarians, as Artrotrobus annulatus, Dictyophimus gracilipes, Acanthocorys umbellifera. 
5. Station S. Aug. 20th. Lat. 81°14’. Long. 22° 50'E. 
a. Haul 1O—O m. Temp. at 0 m. 0,38, sal. 32,49. Temp. at 10 m. 1,18, sal. 33,42. 
Plankton chiefly trichoplankton (most common: Chetoceros borealis, C. bor. v. Brightwelli, 
C. criophilus, Rhizosolenia obtusa and Thalassiosira gravida) and sparingly arctic neritic 
plankton (Chetoceros diadema, Leptocylindrus danicus). 
6. Haul 25—0 m. Temp. at 30 m. 3,3. Sal. 34,41. The same as a. 
c. Haul 130—O m. Temp. at 100 m. 1,7, at 150 m. 1,98. Sal. at 100 m. 34,77, 
at 150 m. 34,83. Plankton as in a, but some animals indicate the presence of styli- 
plankton. 
6. Station T. August 27th. Lat. 79°58'N. Long. 9° 35’E. 
a. Haul 10—O m. Temp. at 0 m. 4,58. 8S. 34,53. This gathering contained the 
following: 
Trichoplankton with northern and 
Cheetoplankton. arctic neritie plankton. Styliplankton. 
Chetoceros borealis r, Chetoceros atlanticus r, Rhizosolenia gracillina +, 
C. criophilus ce, C. borealis r, R. hebetata r, 
C. decipiens 1, var. Brightwellit +, R. styliformis r. 
Phaeocystis Pouchetii +. C. criophilus e, 
C. diadema ec, 
C. teres r, 
Leptocylindrus danicus r, 
Thalassiosira gravida ce, 
Dinobryum r. 
The plankton is thus constituted principally of trichoplankton with some arctic or 
northern neritic plankton and contains a small amount of cheeto- and styliplankton. 
b. Haul 100—0O m. Temp. at 100 m. 3,7. Sal. 35,12. Plankton similar to a, 
but contained besides Globigerina, Challengeria tridens, Plectophora arachnoides, which 
indicate an increased amount of styliplankton. 
ce. Haul 400—0O m. Temp. at 430 m. 1,5. Sal. 35,06. 
Similar to 6 but with some additional styliplankton-forms as Diplopsalis lenticula (rr), 
Chet. borealis var. solitaria (r), Chetos. volans (r), Otthona plumifera, Onceea minuta, 
indicating an increased amount of styliplankton. This sample was examined for radio- 
larians, of which several new forms were found. Among known species were found 
Challengeria Harstoni and Dictyophimus gracilipes as in the deep-sea haul at the station O
