efficiency of algal photosynthesis.

The process by which phytoplankton communities sequester carbon dioxide is known as the "biological pump." In theory, CO2 enters the ocean from the atmosphere, and the carbon is taken in by phytoplankton via photosynthesis. Then, some of the carbon is taken in by other organisms, such as fish and zooplankton, which eat the phytoplankton. Those organisms release carbon dioxide back into the water and atmosphere. The rest of the phytoplankton's carbon, however, is transported to the depths of the ocean, as dead phytoplankton sinks and either decomposes or gets deposited on the ocean floor as sediment. Because a portion of the carbon taken in by the phytoplankton is constantly being sent to the ocean bottom - a sink in which the carbon will remain for a very long time - this process is often viewed as an effective long-term form of sequestration ().

Our projects in Green Technologies seek to use our previous studies and our understanding of microorganisms growing in extreme environments in a number of promising technologies. We are currently focusing on technologies that use photosynthesis in algae (Earth’s smallest, oldest, and toughest plants) for food production, biofuels, and wastewater treatment.

Even if phytoplankton growth is greatly increased, the effect of this on atmospheric CO2 might still be limited or negligible. The majority of the dissolved inorganic carbon (DIC) in the Southern Ocean is in the form of bicarbonate (HCO3-), concentrations of which are unaffected by anthropogenic CO2 increases. Uptake of DIC by phytoplankton for photosynthesis is split roughly half-and-half between HCO3- and CO2 – a ratio that does not change as phytoplankton productivity increases with iron fertilization – rendering phytoplankton at least partially insensitive to CO2 levels ().

Maximizing the efficiency of natural and engineered photosynthesis is therefore of utmost importance.
A food chain is a means of transferring the energy from photosynthesis to support many forms of life, including us!

s humanity faces more mouths to feed thanks to a swelling global population, new research has taken a step toward employing genes from blue-green algae to improve staple crop photosynthesis — a potential improvement that could boost plant efficiency and increase yields.

Beyond providing transport energy and chemical feedstocks, photosynthesis will continue to be used for food and feed applications.

Phytoplankton are microscopic marine plants, commonly single-celled. They float in the uppermost layer of the ocean water column - called the "photic zone," because it is defined by the depth to which sufficient sunlight for photosynthesis reaches - and rely upon sunlight, water, dissolved carbon dioxide, and trace dissolved nutrients in order to grow. These tiny ocean plants, by virtue of their high primary productivity and their potential to become more productive still with iron fertilization, have been touted as holding the key to preventing global climate change (). This may or may not be true, but if left alone, phytoplankton could actually become less productive rather than more ().
