From: Deep Gulf of Mexico seeps are not a significant source of methane to the atmosphere

Fig. 1

Yellow polygons (with white lines) represent the seep anomalies identified by the Bureau of Ocean Energy Management (BOEM). Vertical 14C-CH4 distributions were investigated at the BHS, SS, and Background sites, and surface-only samples were collected from the ATGOM-U9, -U10, -U12, and MR plume sites.
