Parameter: pheophorbide a

Short Description: pheophorbide a

Short Name: p_phorbide

Official Name: pheophorbide a

Units: milligrams/meter3

No Data Value: nd

Description

pheophorbide a (or pheide) from chlorophyll a; measured by HPLC method, it is also reported in micrograms/liter or mole percent; pheophorbide is obtained from chlorophyll or pheophytin by treatment with hydrochloric acid. CAUTION: this measurement is reported from both plankton and sediment samples.
