Methane flux from sediment into near-bottom water in the coastal area of the Puck Bay (Southern Baltic)

This work presents the results of the study on methane emission from the sea bottom in the coastal zone of Puck Bay. The investigations were conducted from June through September 2010 at seven sampling sites located along the Hel Peninsula. The research results indicate that the methane flux rates vary periodically. Methane emission from seabed into near-bottom water in the coastal zone of Puck Bay along the Hel Peninsula ranged from 0.91 mmol m−2 d−1 to 49.15 mmol m−2 d−1.
