DEPOSIT-SAMPLES 



"Michael Sars" Station 51. 5tli-(Uli June, 1910. 

 Lat. 31' 20' N., Long. 35' 7' W.; Depth — 3886 ni. (2121 fms.). 



GLOBIGERINA OOZE: light fawn or cream coloured, 

 granular. 

 CALCIUM CARBONATE (87-58 per cent.): — pelagic and 

 bottom-living Foraminifera, Echinoid spines, 

 coccoliths, rhabdoliths, primordial cells of 

 Foraminifera. 

 RESIDUE (12-42 per cent.): — 



Siliceous Organisms [less than 1 per cent.]; 



one or two splinters of Sponge spicules. 

 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 [10-42 per cent.]; amorphous 



clayey matter with minute mineral particles. 



Note: The sounding-tube at this Station sank deeply 

 into the deposit, the outside being marked for a distance 

 of about 46 cm. (about 18 inches), but the sample recei- 

 ved is about 10 cm. (4 inches) in length, and apparently 

 uniform throughout. 



"Michael Sars" Station 54. lOtli June, 1910. 

 Lat. 35° 37' N., Long. 30" 15' W.; Dcpth-3185 m. (1739 fms.). 



GLOBIGERINA OOZE: dirty white colour, coherent, 

 granular. 



CALCIUM CARBONATE (84-93 per cent.):— pelagic and 

 bottom-living Foraminifera, Ostracods, cocco- 

 liths and rhabdoliths. 

 RESIDUE (15-07 per cent.]: - 



Siliceous Organisms [1 per cent.]; Sponge spic- 

 ules, Radiolaria, Diatoms. 

 Minerals [1 percent.]; m.di.0-06 mm., angular, 

 orthoclase (?), volcanic glass, decomposed 

 ferruginous mineral. 

 Fine Washings [13-07 per cent.]; amorphous 

 clayey matter with minute mineral particles. 



Note: The sounding-tube brought up a roll about 

 6 inches in length of a uniform creamy white colour. 

 Marks were observed outside the lube for a distance of 

 54 cm. (about 21 inches). 



"Michael Sars" Station 53. 8th .hine, 1910. 

 Lat 34^59' N., Long 33^ 1' W; Depth- 2615 m. (1428 fms.). 



GLOBIGERINA OOZE: dirty white colour, coherent, 

 granular. 

 CALCIUM CARBONATE (92-15 per cent.): — pelagic and 

 bottom-living Foraminifera, Echinoid spines, 

 coccoliths, rhabdoliths. , 



RESIDUE (7-85 per cent.): — 



Siliceous Organisms [2 per cent.]: Sponge spic- 

 ules, Radiolaria, arenaceous Foraminifera, 

 Diatoms. 



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

 two colourless particles exceeding 0-05 mm. 

 in diameter were observed. 



Fine Washings [4-85 per cent.]; amorphous 

 clayey matter with minute mineral particles 

 too small for identification. 



Note: The sounding-tube brought up a roll about 

 8 inches in length of a uniform almost white colour. Marks 

 were observed outside the tube for a distance of 50 cm. 

 (20 inches). 



"Michael Sars" Station 55. 10th June, 1910.

GLOBIGERINA OOZE: dirty white colour, coherent, 

 granular. 

 CALCIUM CARBONATE (78-59 per cent.);— pelagic and 

 bottom-living Foraminifera, Ostracods, cocco- 

 liths and rhabdoliths. 

 RESIDUE (21-41 per cent.):-- 



Siliceous Organisms [2 per cent.]; Radiolaria, 



Sponge spicules. 

 Minerals [4 per cent.]; m.di. 0-09 mm., one 

 angular fragment of volcanic glass e.xceeded 

 2 mm. in length; quartz, plagioclase, vol- 

 canic glass, augite (?), magnetite, mica. 

 Fine Washings [15-41 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 througiiout.
