Patterns of Dissolved Organic Matter Lability among Systems

PATTERNS OF DISSOLVED ORGANIC MATTER LABILITY AMONG SYSTEMS 

The data on percentage of DOM consumed for marsh sites were sparse and there were gaps in the time coverage, especially in the long time intervals, and it was difficult to fit a represents power equation for marsh data. The available bioassays of marsh marine DOM showed low initial (1-to 3-day incubation) lability (approximately 9%), but extremely high lability 

TABLE II Change in Percentage of DOC Consumed (%DOC) with Incubation Time (days) for All Data Grouped into Five Main System Categories 

Note The percentage of DOC consumption rate (y) versus the incubation time (x) relationship fits a power model y = axb. There were insufficient marsh time points to fit a power equation.
