Phytoplankton biomass in the world's oceans amounts to only ∽1–2% of the total global plant carbon, yet these organisms fix between 30 and 50 billion metric tons of carbon annually, which is about 40% of the total. On geological time scales there is profound evidence of the importance of phytoplankton photosynthesis in biogeochemical cycles. It is generally assumed that present phytoplankton productivity is in a quasi steady-state (on the time scale of decades). However, in a global context… 
Photosynthetic performance and productivity of phytoplankton in the Southern Ocean
TLDR
Strong negative relationships between iron, temperature, and photoprotective pigments demonstrate that cells were producing more photoproctive pigments under low temperature and iron conditions, and are responsible for the low biomass and low productivity measured in the PFZ.
Carbon fixation and carbon availability in marine phytoplankton

TLDR
It is suggested that short-term photosynthesis, production rate, and achieved biomass, of phytoplankton are rarely limited by inorganic C supply but, rather, that the widely suggested factors of limited light, nitrogen or phosphorus supply are the resource inputs which restrict productivity.
Significant organic carbon acquisition by Prochlorococcus in the oceans
Marine phytoplankton are responsible for about half of the photosynthesis on Earth. Many are mixotrophs, combining photosynthesis with heterotrophic assimilation of organic carbon but the relative
Constraint on net primary productivity of the global ocean by Argo oxygen measurements
The biological transformation of dissolved inorganic carbon to organic carbon during photosynthesis in the ocean, marine primary production, is a fundamental driver of biogeochemical cycling, ocean
Both respiration and photosynthesis determine the scaling of plankton metabolism in the oligotrophic ocean
TLDR
The results show that the scaling of plankton metabolism by generalized P:R relationships that has sustained the debate is biased, and indicate that the variability of R, and not only of P, needs to be considered in regional estimations of the ocean's metabolic state.
Global Change Impacts on Phytoplankton Communities in nutrient- poor Lakes
Phytoplankton communities are recognized as important indicators for environmental changes since they usually respond rapidly to a changing environment in aquatic systems. To evaluate how changes in

TLDR
An extensive global carbon sequestration programme has the potential to make a particularly significant contribution to controlling the rise in CO2 emissions in the next few decades, but even the maximum amount of carbon that could be sequestered will be dwarfed by the magnitude of fossil–fuel emissions.
Global patterns in oceanic planktonic metabolism
Rates of gross primary production (GPP) and respiration (CR) of plankton communities in the upper ocean were evaluated on the basis of a data set comprising 3149 paired light and dark bottle
Effect of enhanced CO_2 level on the physiology and ecology of phytoplankton
TLDR
The development of the methodology for studying the effect of enhanced CO2 level on water ecosystems is summarized and it is expected that effects on algal productivity in eutrophic aquatic ecosystems could be potentially larger.
Nutrient and temperature constraints on primary production and net phytoplankton growth in a tropical ecosystem
The Red Sea depicts a north–south gradient of positively correlated temperature and nutrient concentration. Despite its overall oligotrophic characteristics, primary production rates in the Red Sea

An alternative approach to diagnosing iron-limitation uses molecules whose abundance increases in response to iron- Limitation, including cell surface iron-transport proteins, and the electron transfer protein flavodoxin which replaces the Fe-S protein ferredoxin in many Fe-deficient algae and cyanobacteria.

The plankton multiplier—positive feedback in the greenhouse
TLDR
A mathematical model of the upper ocean ecosystem, based on the Lagrangian Ensemble method, concludes that increasing radiative forcing by 5 W m− (equivalent to doubling atmospheric CO2) reduces the deep flux of paniculate carbon by 10%, which means that the plankton multiplier will increase the rate of climate change in the 21st century.
