Observational data compilation in 1-degree grid cells:

Data compilation of small tunicates (appendicularians, mg C m-3) and large tunicates (thaliaceans, mg C m-3) as described in the Luo et al. publication. 

Mesozooplankton from the COPEPOD carbon biomass dataset in mg C m-3 (Moriarty and O'Brien 2012).

The chlorophyll growing season mean (from GlobColour data product, blended in the Southern Ocean with Johnson et al. 2013), in units of mg Chl m-3.

The tunicate column is a simple addition of the appendicularian + thaliacean column, assuming missing values are zero (use with caution). 

Please note that these values do not incorporate the 10x biomass adjustment from net-based sampling; this must be added in afterwards.
