Variable General Info
Oyster biomass (dry tissue per oyster) ?Comment:"SH to dry tissue mass conversions from the respective regions (South Carolina and Florida) were applied...Where estuary-specific conversions from SH to dry tissue mass were not available, convsions from the nearest available estuary within the same ecoregion (Spalding et al. 2007) were applied." |
Oyster filtration rate (per oyster) ?Comment:"Of the multiple variables known to influence oyster filtration, we determined that water temperature and oyster size (shell height from umbo to the posterior edge; SH) were the key variables for which we could obtain data nationally (Table 1)." |
