Description/Abstract/Artist Statement

Blue carbon is stored in coastal and marine ecosystems like seagrass meadows and salt marshes, which helps combat climate change by preventing greenhouse gas emissions. This study examines the role of seagrass in carbon storage by comparing sediment cores from a mud channel and a seagrass meadow in South Bay.

We collected a 100 cm core from the mud channel and a 55 cm core from the seagrass area, taking samples every 10 cm to analyze grain size and organic carbon content. Using a wet sieving method, we separated sand from mud and measured organic carbon through loss on ignition.

The findings showed no significant increase in carbon storage in seagrass sediments. Differences in grain size highlighted the effect of water movement on sediment deposition. The study concluded that seagrass meadows do not significantly enhance below-ground carbon storage, indicating that muddy environments are more important for storing organic material than the presence of plants alone.
