Short summary
Short summary
We have modelled how gas seeping from the seafloor spreads in the ocean and how much reaches the atmosphere. We estimate how much free gas dissolves in water, atmospheric release and 3-D concentration using data from a hydrodynamic model and gas loss modules. We applied the framework to a methane (CH4) seep site offshore Norway showing that atmospheric CH4 release is spread over a large area. However, with our assumptions, most of the CH4 (>90 %) is converted to CO2 by microbes.

Sensors capable of measuring rapid fluctuations are important to improve our understanding of environmental processes. Many sensors are unable to do this, due to their reliance on the transfer of the measured property, for instance a gas, across a semi-permeable barrier. We have developed a mathematical tool which enables the retrieval of fast-response signals from sensors with this type of sensor design.

Short summary
Seafloor methane emissions associated with cold-water corals have been reported worldwide. Yet, there are still knowledge gaps regarding their ecological relationships. We studied the geology, chemistry and biology of methane seeps in a coral area off northern Norway. We found that corals thrive in areas with methane-rich sediments and benefit from strong currents that deliver food, but the seep activity itself does not directly determine coral distribution.

Short summary
We investigate organic matter composition in the Arctic Ocean water column. We collected seawater samples from sea ice to deep waters at six vertical profiles near an active hydrothermal vent and its plume. In comparison to seawater, we found that the organic matter in waters directly affected by the hydrothermal plume had different chemical composition. We suggest that hydrothermal processes may influence the organic matter distribution in the deep ocean.

Short summary
Natural sources of atmospheric methane need to be better described and quantified. We present time series from ocean observatories monitoring two seabed methane seep sites in the Arctic. Methane concentration varied considerably on short timescales and seasonal scales. Seeps persisted throughout the year, with increased potential for atmospheric release in winter due to water mixing. The results highlight and constrain uncertainties in current methane estimates from seabed methane seepage.
