(REP. OF THE "MICHAEL SARS" NORTH 



From this station Dr. Peach records more than three 

 hundred rock specimens, mostly glaciated, varying from 

 ^8 to over 2 inches in greatest diameter, together with 

 eighty pieces of clinkers, cinders and coal. The sedi- 

 mentary rocks include greywacke, grit, limestone, shale 

 and chalk; the metamorphic rocks include gneiss and 

 schist; and among igneous rocks there are granite, diorite, 

 gabbro, quartz-syenite, dolerite, and basalt. 



•Michael Sars" Station 19. 2nd May, 1910. 

 Lat. 36° 5' N., Long 4" 42' W. (Mediterranean Sea); Depth— 1000 m. 



(547 fms.). 



BLUE MUD: greenish-grey, coherent, fine-grained, lustrous 

 streak. 

 CALCIUM CARBONATE (16-9 per Cent.) :— pelagic and 



bottom-living Foraminifera. 

 RESIDUE (83.1 per cent.):— 



Siliceous Organisms [1 per cent.]; Sponge 



spicules. 

 Minerals [3 per cent.]; mostly angular, m. di. 

 0-08 mm., quartz, orthoclase, decomposed 

 glass. 

 Fine Washings [79-1 per cent.]; clayey matter 

 with minute mineral particles. 



Note: A section about 4 inches in length, of uni- 

 form appearance throughout, came up in the sounding- 

 tube (lead tube, Iversen's patent). 



'Michael Sars" Station 20. 5th May, 1910. 

 Lat. 35° 25' N., Long. 6° 25' W. (Straits of Gibraltar); Depth— 153m. 



(84 fms.). 



BLUE MUD: brownish-grey, granular, coherent, with 

 large fragments of Mollusc shells embedded in 

 the deposit. 

 CALCIUM CARBONATE (33-06 per cent.):— pelagic and bot- 

 tom-living Foraminifera, Echinoid shell frag- 

 ments and spines. Mollusc fragments, Ostracods, 

 one or two coccoliths, one or two Pteropod 

 fragments. 

 RESIDUE: (66-94 per cent.): — 



Siliceous Organisms [1 per cent.]; Radiolaria, 



Sponge spicules, glauconitic casts. 

 Minerals [50 percent.]; angular and rounded, 

 m. di. 0-12 mm., principally quartz, with a 

 few grains of glauconite, decomposed fels- 

 par and a ferruginous mineral; mica. 

 Fine Washings [15-94 per cent.]; clayey matter 

 with minute mineral particles. 

 Note: The material examined was obtained by the 

 trawl, but was quite coherent and showed no signs of 

 having been washed in any way. It was therefore taken 

 to represent the deposit at the bottom. 



'Michal Sars' Station 21. 5th May, 1910. 

 Lat. 35' 31' N., Long. 6 35' W; Depth-535 m. (293 fms.). 



BLUE MUD: brownish, extremely coherent and clayey, 

 lustrous streak. 

 CALCIUM CARBONATE (27-24 per cent.):— pelagic and 

 bottom-living Foraminifera, fragments of Ptero- 

 pods, Gasteropods and Lamellibranchs, Echi- 

 noid spines, Ostracods, and a very few coccoliths 

 and rhabdoliths. 

 RESIDUE (72-76 per cent.): — 



Siliceous Organisms [1 percent.]; fragments of 



arenaceous Foraminifera. 

 Minerals [3 per cent.]; rounded and angular, 



m. di. 008 mm., quartz, orthoclase. 

 Fine Washings [68-76 per cent.]; mostly very 



minute mineral particles with amorphous 



clayey matter. 



Note: The material here described was obtained 

 by the trawl. A few shells of Dentalium and other 

 Molluscs were visible here and there, embedded in the 

 clayey matrix. The mineral particles exceeding 0.05 mm. 

 in diameter are few in number. 



'Michael Sars" Station 23. 5tli-6th May, 1910. 

 Lat. 35 32' N., Long. T T W. ; Depth-1215 m. (664 fms.). 



At this station apparently no sounding was taken, 

 but the Petersen net was sent down with 1500 metres 

 (820 fathoms) of line and hauled throughout the night 

 between the 5th and 6th of May. When hauled up it 

 was found to contain a very large amount of empty 

 Pteropod shells, the principal species being tiyalea Inflexa, 

 with here and there Cleodora pyramidata and other 

 species of Pteropods, Lamellibranch shells, arenaceous and 

 other bottom-living Foraminifera, Sponge spicules and 

 Worm tubes. 



From this station Dr. Peach records two pieces of 

 clinker, the larger, over six inches in length, having a 

 simple coral attached, and from Station 24, 1615 metres 

 (883 fathoms), three pieces of clinker having siliceous 

 Sponges, Serpulae, and Brachiopods attached.
