Abstract
The model integrates the effect of the photo-acclimation processes on the “active” fraction of the phytoplankton population with the dynamic of the water column, parametrised through a series of laboratory experiments based on in vivo variable fluorescence measures on the marine diatom Skeletonema costatum (Greville) Cleve. The performance of Phyto-VFP was compared with concurrent estimates of radiocarbon (14C) uptakes, under different dynamic and optical conditions, during two oceanographic cruises (SAMCA3 and SAMCA4) in the Mediterranean Sea. The low Root Mean Square Differences (RMSDs) show that Phyto-VFP performs well when estimating phytoplankton PP. When compared to other biooptical models, Phyto-VFP estimates of PP in coastal waters were closer to radiocarbon measurements than other models could predict [e.g., the Morel model (MM)].File | Dimensione | Formato | |
