Fig. 1. Location of mooring sites in context of productivity pattern for the Atlantic Ocean presented by Berger
(1989; contours in gC m· 2 Y'!), and comparison of average fluxes in g m· 2 for each mooring site. Since most trapping
experiments extended over 351-381 days (Table I), mean values were extrapolated to 365 days (one year) except for
the 1991 Eastern Equatorial N-S transect (EA 1-5) where sampling duration was 230 days. For deployment data see
Table I.
