Supplemental Table
Supplemental Table S1 - In situ rate measurements made during Lagrangian cycles.
Columns are: 1) Cruise and cycle identifiers. 2) Depth at which export measurements
(234Th and/or sediment traps) were made. 3-4) Start and end dates of cycles. 5-8)
Location of cycles. 9) Depth of the euphotic zone (1% light level). 10) 14CPP. 12)
Fraction of microphytoplankton (>20-m) as determined from vertical integration of
carbon-based epifluorescence microscopy data. 14) Fraction of microphytoplankton
(>20-m) as determined by size-fractionated Chl a measurements made in the mixed
1
layer. 16) Water-column integrated phytoplankton specific growth rate as determined
from microzooplankton grazing dilution experiments. 18) Water-column integrated
protozoan grazing rates as determined from microzooplankton grazing dilution
experiments. 20) Euphotic zone mesozooplankton grazing rates as determined from gut
pigment measurements made from paired day-night oblique bongo tows. 22) Vertical
carbon-flux measurements determined using the 238U-234Th disequilibrium method. 24)
Vertical carbon-flux measurements determined using VERTEX-style drifting sediment
traps. 26) Specific rate of change of vertically integrated in situ Chl a at the drifter
location. 28) Vertically integrated phytoplankton biomass determined by epifluorescence
microscopy (for all cycles on CCE-P0605, CCE-P0704, and CCE-P0810 and CRD
Cycles 2-4) or by multiplication of vertically integrated Chl a by a region-specific C:Chl
a ratio determined from our dataset (43 for CCE and 119 for CRD, g:g). For all
measurements, standard error (SE) of replicate measurements made during the
Lagrangian experiments are reported.
