IREP. OF THE "MICHAEL SARS" NORTH 



"Michael Sars" Station 37. 2()th May, 1910. 

 Lat. 26' 6' N., Long. 14 33' W.; Depth — 47 m. (26 fins.). 



This sample consists of a portion of the "arming" 

 from the sounding-lead, in which are embedded Mollusc 

 shells and fragments, arenaceous and other bottom-living 

 Foraminifera, and mineral particles. 



•Michael Sars" Station 37. 20th May, 1910. 

 Lat. 26° 6' N., Long. 14° 33' W. ; Deptli — 42 m. (23 fms.). 



This sample consists of a portion of the "arming" 

 of the'" lead, in which are embedded Mollusc shells and 

 their fragments, otoliths of Fishes, bottom-living Foram- 

 inifera, Bryozoa, Echinoid spines, mineral particles, etc. 



•Michael Sars" Station 41. 23rd May, 1910. 

 Lat. 28° 8' N., Long 13° 35' W.; Depth — 1365 m. (746 fms.). 



GLOBIGERINA OOZE: fawn colour, coherent. 



CALCIUM CARBONATE (57-02 per cent.):— pelagic 'and 

 bottom-living Foraminifera, Echinoid spines, 

 coccoliths, rhabdoliths. 

 RESIDUE (42-98 per cent).:— 



Siliceous Organisms [1 per cent.]; arenaceous 

 Foraminifera and fragments, Sponge spicules. 

 Minerals [1 per cent.]; only one or two quartz 

 grains exceeding 0-05 mm. in diameter were 

 observed. 

 Fine Washings [40-98 per cent.]; clayey matter 

 with many minute mineral particles. 



"Michael Sars" Station 47. 30th May, 1910. 

 Lat. 29° 2' N., Long. 22° 53' W.; Depth —5160 m. (2817 fms.). 



GLOBIGERINA OOZE: fawn coloured, finely granular, 

 coherent. 

 CALCIUM CARBONATE (60-99 per cent.): —pelagic and 

 bottom-living Foraminifera, Echinoid spines, 

 coccoliths, rhabdoliths. 

 RESIDUE (39-01 per cent.):— 



Siliceous Organisms [1 per cent.]; Sponge 



spicules, fragments of Radiolaria. 

 Minerals [2 per cent.]; mostly angular, m. di. 



0-07 mm., quartz, mica. 

 Fine Washings [36-01 per cent.]; amorphous 

 clayey matter with small mineral particles. 



Note: The sounding-tube brought up a roll about 

 13 inches in length of uniform appearance throughout. 



.Michael Sars' Station 48. 31st May, 1910. 

 Lat. 28° 54' N., Long. 24° 14' W. ; Depth — not stated. 



The only material received is an earbone of a whale, 

 much corroded, the traces of deposit adhering to it 

 indicating apparently a Globigerina Ooze. Unlike nearly 

 all the earbones dredged by the „Challenger", no trace 

 of manganese could be seen on this one. 



From this station Dr. Peach records two chips of 

 chalk-flint, a small fragment of epidiorite or hornblende 

 schist, ice-moulded and coated with manganese peroxide, 

 four fragments of decomposed basalt, and over sixty 

 rounded fragments of pumice. 



"Michael Sars" Station 49 C. lst-2nd June, 1910. 

 Lat. 29° 7' N., Long. 25' 32' W.; Deptli — 5425 m. (2966 fms.). 



GLOBIGERINA OOZE: fawn coloured, finely granular, 

 coherent. 

 CALCIUM CARBONATE (64-31 per cent.): — pelagic and 

 bottom-living Foraminifera, Echinoid spines, 

 Ostracods, coccoliths and rhabdoliths. 

 RESIDUE (35-69 per cent.):— 



Siliceous Organisms [less than 1 per cent.]; 



only one or two broken Sponge spicules were 



observed during the examination of the 



material. 

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



two mineral particles exceeding 0-05 mm. 



in diameter could be detected — apparently 



all quartz. 

 Fine Washings [33-69 per cent.]; amorphous 



clayey matter with minute mineral particles. 



Note: The sounding-tube had sunk deeply into the 

 deposit and brought up a section about 14 inches in 

 length. As frequently happens when such a long section 

 is brought up, traces of stratification were distinctly visible, 

 more especially towards the upper end, although the lower 

 end presents quite a mottled appearance with patches of 

 lighter and darker brown. Towards the upper end small 

 patches were observed of a dark brown colour, which 

 upon examination proved to be Red Clay, a small portion 

 analysed giving only 25-08 per cent, of calcium caibonate. 

 This Red Clay, however, forms but an insignificant pro- 

 portion of the total sample, the deposit being in reality 

 a Globigerina Ooze as in the detailed description, which 

 is based upon material taken from the middle of the 

 section. This sounding, the deepest cast made during 

 the cruise, suggests the proximity of an unknown "deep", 

 or an extension southwards of the Monaco Deep.
