MAREDAT: towards a world atlas of MARine Ecosystem DATa
We present a summary of biomass data for 11 plankton functional types (PFTs) plus phytoplankton pigment data, compiled as part of the MARine Ecosystem biomass DATa (MAREDAT) initiative. The goal of the MAREDAT initiative is to provide, in due course, global gridded data products with coverage of all...

| description | We present a summary of biomass data for 11 plankton
functional types (PFTs) plus phytoplankton pigment data, compiled as part of
the MARine Ecosystem biomass DATa (MAREDAT) initiative. The goal of the
MAREDAT initiative is to provide, in due course, global gridded data
products with coverage of all planktic components of the global ocean
ecosystem. This special issue is the first step towards achieving this. The
PFTs presented here include picophytoplankton, diazotrophs,
coccolithophores, <i>Phaeocystis</i>, diatoms, picoheterotrophs, microzooplankton,
foraminifers, mesozooplankton, pteropods and macrozooplankton. All variables
have been gridded onto a World Ocean Atlas (WOA) grid (1° × 1° × 33
vertical levels × monthly climatologies). The results show that abundance is much better constrained
than their carbon content/elemental composition, and coastal seas and other
high productivity regions have much better coverage than the much larger
volumes where biomass is relatively low. The data show that (1) the global
total heterotrophic biomass (2.0–4.6 Pg C) is at least as high as the
total autotrophic biomass (0.5–2.4 Pg C excluding nanophytoplankton and
autotrophic dinoflagellates); (2) the biomass of zooplankton calcifiers (0.03–0.67 Pg C)
is substantially higher than that of coccolithophores (0.001–0.03 Pg C);
(3) patchiness of biomass distribution increases with organism size; and
(4) although zooplankton biomass measurements below 200 m are rare, the limited
measurements available suggest that <i>Bacteria</i>
and <i>Archaea</i> are not the only important
heterotrophs in the deep sea. More data will be needed to characterise ocean
ecosystem functioning and associated biogeochemistry in the Southern
Hemisphere and below 200 m. Future efforts to understand marine ecosystem
composition and functioning will be helped both by further archiving of
historical data and future sampling at new locations.
