Temperature, salinity, nutrients and chlorophyll a in coastal waters of the Southern California Bight
The seasonal variability of dissolved inorganic nutrients (phosphates, PO–34; nitrates, NO–3; nitrites, NO–2) and chlorophyll a was studied during five surveys in nearshore waters of the southern region of the Southern California Bight (SCB). The seasonal changes in the physical properties of the ar...

The seasonal variability of dissolved inorganic nutrients (phosphates, PO–34; nitrates, NO–3; nitrites, NO–2) and chlorophyll a was studied during five surveys in nearshore waters of the southern region of the Southern California Bight (SCB).
