Approximately 45% of the photosynthetically fixed carbon on Earth occurs in the oceans in
phytoplankton, which account for less than 1% of the world's photosynthetic biomass. This …

Commercial marine organisms were collected from the coast of **angshan Bay to
investigate the concentrations of eight heavy metals (As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn) and …

Variable fluorescence techniques are increasingly used to assess phytoplankton
photosynthesis. All fluorescence techniques and models for photosynthetic electron …

Assessing phytoplankton productivity over space and time remains a core goal for
oceanographers and limnologists. Fast Repetition Rate fluorometry (FRRf) provides a …

During winter in the Arctic marine ecosystem, diatoms have to survive long periods of
darkness caused by low sun elevations and the presence of sea ice covered by snow. To …

Phytoplankton are extraordinarily diverse, comprising 13 phylogenetic groups, with diatoms,
dinoflagellates, and haptophytes among the most prominent eukaryotes in the ocean …

Microbial community metabolic balance (ie, the ratio between photosynthesis and
community respiration) is critical for assessing the strength of the biological carbon pump …

Understanding the dynamics of marine phytoplankton productivity requires mechanistic
insight into the non-linear coupling of light absorption, photosynthetic electron transport and …

Phytoplankton primary productivity (PP) varies significantly over environmental gradients,
particularly in physically‐dynamic systems such as estuaries and coastal seas. During …

The approach of fast repetition rate fluorometry (FRRF) requires a conversion factor (Φe: C/n
PSII) to derive ecologically-relevant carbon uptake rates (PP z, t). However, the required Φe …
