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
  1. *Chl a refers to chlorophyll a, a proxy for algal biomass that can be expressed as either a concentration or a content
