Implication

Observational analysis reveals coupled degradation of phosphorus and chlorophyll in marine particulate matter, indicating carbon and nitrogen persist longer as detritus.

Key Points

Determine the elemental and pigment relationships among carbon, nitrogen, phosphorus, and chlorophyll in particulate organic matter.
Analyzed particulate organic matter samples collected across the western North Atlantic.
Calculated linear regression relationships between phosphorus, chlorophyll, nitrogen, and carbon concentrations, assessing intercept values extrapolated toward the origin.
Regressions of phosphorus or chlorophyll against nitrogen or carbon yield positive intercepts, showing substantial residual carbon and nitrogen in the absence of phosphorus and chlorophyll.
Regression of phosphorus against chlorophyll intersects the origin, demonstrating that chlorophyll and phosphorus mineralize at essentially the same rate while carbon and nitrogen are more refractory.
