PLATE 21 



Figs. A-F. — Station 36, lower slope, south of Nyckel Ridge, 810-815 fms. 



A-F, Muddy, largely clayey, bottom (see clouds in A and B). Granular texture, 

 particularly apparent in C and E, may be produced by faecal pellets or sediment 

 clasts. Halosaur fish, such as that in B, may produce linear tracks of the type 

 shown in B and C (arrow). Burrow in lower left corner of E. Sediment clouds 

 in center of F (arrow) may be produced by burrowing organisms. Sea urchin 

 is present in D.
