[REP. OF THE "MICHAEL SARS" NORTH 



"Michael Sars" Station 56. lOth-Uth June, 1910. 

 Lat. aS^SS'N., Long. 29°47'W.; Depth— 3239 m. (1768 fms.). 



GLOBIGERINA OOZE: creamy white, granular, coherent. 

 CALCIUM CARBONATE (71-25 per cent.):— pelagic and 

 bottom-living Foraminifera, Echinoid spines, 

 Ostracods, coccoliths, rhabdoliths. 

 RESIDUE (28-75 per cent.):— 



Siliceous Organisms [2 per cent.] ; Sponge spi- 

 cules, Radiolaria. 

 Minerals [4 per cent.]; mostly angular, m.di. 



0-09 mm., quartz and mica. 

 Fine Washings [22-75 per cent.]; amorphous 

 clayey matter with minute mineral particles. 

 Note: The sounding-tube brought up a roll about 

 9 inches in length of a creamy white colour and appa- 

 rently uniform throughout. 



"Michael Sars" Station 58. 12th June, 1910. 

 Lat. 37 37'N,, Long. 29' 25' W.; Depth— 1015 m. (555 fms.). 



Apparently all that came up in the sounding-tube at 

 this Station were a few fragments of peroxide of man- 

 ganese and of Fish otoliths, with one or two attached 

 organisms (Foraminifera, etc.). 



"Michael Sars" Station 63. 22nd June, 1910. 

 Lat. 36" 5' N., Long. 43 58' W. ; Depth— 5035 m. (2749 fms.). 



GLOBIGERINA OOZE: dark fawn coloured, granular, 

 slightly coherent. 

 CALCIUM CARBONATE (53-16 per cent.) :— pelagic Foram- 

 inifera, coccoliths, a few coccospheres and 

 rhabdoliths. 

 RESIDUE (46-84 per cent.]:— 



Siliceous Organisms [2 per cent.]; Radiolaria, 

 Sponge spicules, and fragments of arenaceous 

 Foraminifera. 

 Minerals [less than 1 per cent.]; only one or 

 two particles e.xceeding 0-05 mm. in diameter 

 were observed, augite, felspar (partly de- 

 composed). 

 Fine Washings [43-84 per cent.]; amorphous 

 clayey matter with minute mineral particles. 

 Note: The sounding-tube brought up a roll about 

 12 inches in length. In the small portion examined no 

 bottom-living Foraminifera were observed. This station 

 is near the two "Challenger" stations 66 and 67, and the 

 above description agrees very closely with that of "Chal- 



lenger" station 67, where coccospheres and rhabdoliths 

 were not observed, but where bottom-living Foraminifera, 

 Ostracod valves and Echinoid spines were recorded. 



"Michael Sars" Station 70. 30th June, 1910. 

 Lat. 42"59'N., Long. 51' 15'W.; Depth— 1100 m. (601 fms.). 



From this Station Dr. Peach records seven rock frag- 

 ments, including mudstone, limestone, calcareous sandstone, 

 amphibolite, dolerite, and basalt. 



"Michael Sars" Station 88. 18th July, 1910. 

 Lat. 45" 26' N., Long. 26 45'W.; Depth-3120m. (1703 fms.). 



GLOBIGERINA OOZE: dirty white, slightly coherent, 

 granular. 

 CALCIUM CARBONATE (73-66 per cent.):— pelagic and 

 bottom-living Foraminifera, Echinoid spines, 

 fragments of Molluscs, coccoliths and rhabdo- 

 liths. 

 RESIDUE (26-34 per cent.):— 



Siliceous Organisms [3 per cent.]; Diatoms, 

 Radiolaria, Sponge spicules, fragments of 

 arenaceous Foraminifera. 

 Minerals [20 per cent.]; m.di. 0-15 mm., angular 



and rounded, quartz, orthoclase, mica. 

 Fine Washings [3-34 per cent.] ; amorphous 

 clayey matter with minute mineral particles. 



Note: The sounding-tube brought up a roll about 

 14 inches in length, which showed little difference to the 

 naked eye, although the colour was darker in the lower 

 portion, the upper portion being rather lighter in colour, 

 less coherent, and more granular. The percentage of cal- 

 cium carbonate given in the above description is from the 

 middle portion of the section. Material from near the bot- 

 tom and from near the top of the roll gave respectively 

 62-1 per cent, and 83-79 per cent, of calcium carbonate. 

 Here and there rock fragments are visible to the naked 

 eye, the largest observed being a fragment of limestone, 

 5 by 3 inches in diameter. 



From this station there are also three bags of material, 

 evidently collected by the trawl, consisting principally of 

 Pteropods (chiefly Hyalea trispinosa) and their fragments, 

 intermixed with pelagic and bottom-living Foraminifera, 

 Fish otoliths, Echinoid spines, etc. In view of this large 

 supply of Pteropods it is curious to note that in the small 

 sample from the sounding-tube examined no Pteropods 

 were observed. 



From this station Dr. Peach records some pieces of 

 wood-charcoal, and four pieces of wood bored by Teredo.
