Mapping seagrass and carbon sequestration
The podcast episode explores the potential of using bathymetric LiDAR to map seagrass and measure the amount of carbon sequestration taking place. Seagrass areas are directly related to the amount of carbon stored in the root system underneath. By utilizing bathymetric LiDAR technology, more accurate mapping of seagrass and its potential for carbon sequestration can be achieved, which is crucial for carbon credit markets and conservation efforts. The podcast discusses the role of LiDAR in hydrographic surveying and how bathymetric LiDAR has advanced as an emerging technology over the years.
Blue carbon and seagrass
The podcast delves into the concept of blue carbon, which refers to the carbon stored and managed by the marine environment, specifically in seagrass areas. Seagrass functions as a carbon sink, storing carbon within its extensive root system. However, it differs from a traditional carbon sink as it can release carbon back into the cycle. The discussion highlights the importance of managing and preserving seagrass areas for long-term carbon sequestration.
Mapping seagrass using bathymetric LiDAR
The podcast explains how bathymetric LiDAR is optimized for mapping the shape and size of the seafloor and its applicability in mapping seagrass. Traditionally used for hydrographic purposes, bathymetric LiDAR's capabilities extend beyond mapping seagrass. The technology offers potential for better mapping, measurement, and analysis of seagrass areas, enhancing our understanding of carbon sequestration potential. Bathymetric LiDAR's advantages, such as speed and data density, make it a valuable tool for marine ecosystem monitoring and assessment.
Challenges and opportunities of bathymetric LiDAR
The podcast explores the challenges and opportunities associated with bathymetric LiDAR. These challenges include environmental factors like sediment suspended in the water column, water clarity, and wave action. Flying height and limitations in penetration depth are also discussed. However, bathymetric LiDAR's strengths, such as high-definition data collection, rapid acquisition, and accurate mapping, make it a valuable tool for assessing marine environments, including seagrass areas and carbon sequestration potential.
