Estimation of Carbon Buried Under Seagrass Cast

Type of Presentation

Snapshot

Session Title

Climate change and ocean acidification

Location

2016SSEC

Description

Seagrass has amassed on beaches during strong storms around the world. In the K’omoks estuary (49o 40 min North, 124o 57 min West) off east Vancouver Island, B.C., sloughed detrital material persists along an approximately 500 m long wrack line in the form of a large windrow probably because the hot and dry summers slow bacterial breakdown, its deposited above the high tide line on a gentle mostly vegetated slope and large storms that are capable of dislodging it are infrequent. Under this sloughed detritus for approximately 0.3 m alternating layers of silt/sand and dark material are evident. DNA evidence indicated the presence of eelgrass (Zostera marina) in the cores and fronting wetland. Organic matter and carbon were measured and used to estimate the amount buried in the area. Future work will focus on using feldspar to examine burial rate and measuring the timing and amounts of new additions of detrital eelgrass.
