Table 1 Effects of compaction on biomass data expressed as a concentration or content (Perkins et al. 2003)
From: Assessing diatom-mediated fatty acids in intertidal biofilm: a new conservation concern
|  | Concentration (µg Chl a per mg dry weight sediment) | Content (µg Chl a per cm2 sediment) |
|---|---|---|
Effect of compaction | Enrichment from deeper sediment levels increases dry bulk density | Increase in dry bulk density is offset by inclusion of deeper, less productive layers |
Trend seen in results | Increase in Chl a* concentration | Decrease in Chl a* content |
