# Small Phytoplankton N reserve, Large Phytoplankton N reserve, Microphytobenthos N reserve, Trichodesmium N reserve

## Small Phytoplankton N reserve

Total non-structural biomass of nitrogen of the Small (smaller than 2 micro metres) phytoplankton population. Phytoplankton N reserves divided by Phytoplankton N is a number between 0 and 1 and represents the factor by which phytoplankton growth is inhibited due to the internal reserves of nitrogen.

## Large Phytoplankton N reserve

Total non-structural biomass of nitrogen of the Large (larger than 2 micro metres) phytoplankton population. Phytoplankton N reserves divided by Phytoplankton N is a number between 0 and 1 and represents the factor by which phytoplankton growth is inhibited due to the internal reserves of nitrogen.

## Microphytobenthos N reserve

Total non-structural biomass of nitrogen of the benthic microalgae (fast-sinking diatoms that are suspended primarily in the top layer of sediment porewaters) phytoplankton population. Phytoplankton N reserves divided by Phytoplankton N is a number between 0 and 1 and represents the factor by which phytoplankton growth is inhibited due to the internal reserves of nitrogen.

## Trichodesmium N reserve

Total non-structural biomass of nitrogen of the trichodesmium phytoplankton population. Phytoplankton N reserves divided by Phytoplankton N is a number between 0 and 1 and represents the factor by which phytoplankton growth is inhibited due to the internal reserves of nitrogen.
