We found that the size-abundance relationship, together with the quantity of large zooplankton better explained carbon export than other measures typically used, such as photosynthesis and temperature. Here we use a computer simulation of the global plankton community to investigate how the removal of carbon relates to the plankton community and the steepness of the size-abundance relationship. Since large organisms create fast-sinking particles, the size-abundance relationship could be used to estimate how much carbon is being stored in the deep ocean. The steepness of this вЂњsize-abundance relationshipвЂќ describes the balance between small versus large organisms, and has been argued to reflect how energy is transferred from small to large organisms.

The size composition shows a clear relationship between the number of organisms and their body-size. We argue that these processes are reflected in the size composition of the plankton community. However, how much carbon is locked away and for how long depends on how organisms eat, defecate, and respire. Plankton lock CO 2 away from the atmosphere as they sink to the deep ocean, where carbon can be stored for hundreds of years. Plankton are tiny but extremely abundant aquatic organisms. We conclude by discussing how can we reconcile size spectrum theory with field sampling. Time-lags between phytoplankton and copepods did not strongly affect export or pe-ratio. Community metrics performed better than NPP or SST for both deep export and pe-ratio. We find that carbon export correlates best with copepod biomass and trophic level, whereas the pe-ratio correlates best with the exponent of the size spectrum and sea surface temperature (SST). To resolve time-lags between phytoplankton and zooplankton, we implement the life-cycle of multicellular zooplankton (here represented by copepods). The model generates emergent food-webs with associated size distributions for organisms and detrital particles. Here, we use a global mechanistic size-spectrum model of the marine plankton community to investigate how particulate export and pe-ratio relate to the community size spectrum, community composition, and time-lags between predators and prey. Moreover, the life-cycles of multicellular zooplankton are typically not resolved, restricting the ability of models to represent time-lags that are known to impact carbon export and its efficiency (pe-ratio). However, most global models have relatively simple food-web structures that are unable to generate plankton size spectra. We contend that several of these processes can be captured by the size spectrum of the plankton community.

Start the data acquisition the DataBridge program runs as part of the acquisition process, using the options setВ in step 1.The magnitude and efficiency of particulate carbon export from the ocean surface depends not only on net primary production (NPP) but also on how carbon is consumed, respired, and repackaged by organisms.

If the DatabridgeВ executable is open, close the Databridge executable before proceeding. Press OK.Дouble-click on the Process column cell for the sample for which DataBridge is to run a drop-down list appears. If the process and columnВ are not already present in the sample list, select Samples > Format > Customize, andВ select 'Process' in the options menu.
