FIG. 1. Millipore filtor preparat'ions of part,iculatc organic matter, magnification x 200.
(a) Surface sample, Nova Scotia coastal water, with two amorphous aggregates
above and flakes below, indicatcd by arrows. (b) A similar surface sample treated
with brom phenol blue (protein stain). Flakes show typical deep st,aining reaction.
(c) A mid-depth collection (850 m, Slope Water south of Nova Scotia), also treat
The aggregations that can be seen dimly in several parts of the slide are of the type
charact,erizecl (section IV, B) as '' pale primordia *' of naturally occurring aggregat,es.
There arc numcrons smaller particles which do not show clearly becrtuso of t>ho filtor
background.
