“Diffuse Reflectance Spectroscopy (Vis-Nir-Swir) as a Promising Tool for Blue Carbon Quantification in Mangrove Soils: A Case of Study in Tropical Semiarid Climatic Conditions” with Dr. Gabriel Nuto Nóbrega.
Mangrove forests are some of the most important forests in the world. Mangroves are uniquely adapted to acting as a middleman. They can deal with very high salinity and hide tides, but when the tide drops, they can deal with the low salinity. They act as nurseries for young birds, fish, and large, rare mammals like dugongs and manatees before they are ready to branch out into the ocean. They also have the important ability to act as a carbon sink – they take carbon from the atmosphere and trap it in the soils. Dr. Gabriel Nuto Nóbrega has been working with this aspect of mangrove soils since his undergrad days. He wanted to know just how much carbon mangrove forests have the capability to sequester. However, the act of doing so had proven tricky. Not only were traditional methods not reliably measuring the carbon, but they were leaving a toxic residue behind – not ideal in an important and sensitive ecosystem. His solution was DRS – diffusive reflectance spectroscopy, a technique that is not only friendlier to the ecosystem, but cheaper and easier than traditional methods.
