and micronekton in the northeast tropical Atlantic: abundance, community composition and vertical distribution in relation to different trophic environments.
The organisms also can be classified according to their size as picoplankton (0.2-2 [micro]m), nanoplankton (2.1-20 [micro]m), microplankton (20.1-200 [micro]m), mesoplanktlon (201-2000 [micro]m) and macroplankton
(> 2000 [micro]m) [1, 2].

Then the sample was passed through a 280-[micro]m filter to remove macroplankton
. Finally, samples were taken for determinations of the chlorophyll a concentration (using the spectrophotometric method, Strickland & Parsons 1972) and of the mass of organic and inorganic materials in the seston (gravimetric method).
No longer than 12 h after collection, plankton were sieved twice (3.2 mm and 0.7 mm) to remove macroplankton
Seasonal abundance and vertical distributions of macroplankton

Within 2 h in the laboratory, we removed macroplankton
using 153-[micro]m Nytex screens and then 500 or 1000 mL aliquots were passed through 0.7-[micron]m fiberglass MFSF filters.
