Hyperspectral Remote Sensing for Quantifying Blue Carbon Storage in Coastal Salt Marshes

Coastal salt marshes are essential for global carbon sequestration, playing a vital role in mitigating climate change through the storage of blue carbon. These ecosystems sequester carbon in both plant biomass and sediments, with the ability to store carbon for centuries. However, accurately quantifying blue carbon storage in salt marshes remains challenging due to the dynamic nature of these ecosystems and the limitations of traditional field measurement techniques. Recent advancements in remote sensing technology, particularly hyperspectral remote sensing, offer a promising approach to monitoring salt marshes on a large scale with high spatial and spectral resolution. Hyperspectral sensors provide detailed spectral data, enabling the differentiation of vegetation species, assessment of plant health, and mapping of carbon-rich habitats. Additionally, we explore the latest technological innovations, including satellite-based sensors and unmanned aerial vehicles (UAVs), which enhance data collection in challenging coastal environments.
