Maxon Ngochera receives award

Maxon gathers samples for his research.

SFS PhD student Maxon Ngochera received one of four Teledyne RDI 2013 Academic Product Grants for his research on Lake Malawi in Africa.



Teledyne RDI makes state of the art carbon dioxide sensors for lakes and oceans. Maxon is extremely excited to be awarded this grant, “It shows that my research has the potential to add value and advance our knowledge on the functioning of large lakes,” he states. Teledyne RDI is providing Maxon with the HydroCO2, which measures and monitors CO2 at the bottom of large lakes and oceans. Maxon’s current equipment only allows him to sample at the surface so this grant will allow him to sample the deepest parts of Lake Malawi, which has a maximum depth of 700m.
Maxon’s research is focused on whether large lakes can generate carbon dioxide and examining what roles freshwater lakes may have in climate change. Through his research Maxon is trying to determine if Lake Malawi is a net source or a sink for atmospheric CO2 and the roles of atmospheric nutrient deposition. He also is assessing whether patterns of pCO2 in the lake are similar to those of phytoplankton production. Maxon says, “The overall objective of the current research is therefore to determine the mechanisms that control the balance between autotrophy (organism that are able to make complex organic nutritive compounds from inorganic substances) and heterotrophy (organisms that derive their nutrition from complex organic substances) in Lake Malawi as measured by the air-water CO2 flux.” You can find more information about Maxon’s research here.

Maxon’s research using the HydroCO2 will be displayed in San Diego, California at Teledyne RDI’s ADCPs in Action Users’ Conference, which is taking place from September 29- October 2, 2013. Congratulations, Maxon!
