Below is Malcolm Light’s Arctic methane growth diagram, updated in line with recent mean atmospheric methane concentrations and temperature data.
NOAA mean globally-averaged marine surface data show high increases in methane levels recently, which were used to generate the trends and curves to the year 2030 in above image.

Above data was used to determine a trend line for exponentially increasing atmospheric methane increase, as well as where along the trend lines the surface atmospheric temperature anomalies would occur.
The blue color on the map on the right indicates depth (see scale underneath).
The image below, by Malcolm Light and based on Max & Lowrie (1993), from a recent post, shows vulnerable Arctic Ocean slope and deep water methane hydrates zones below 300 m depth.
Malcolm Light indicates three areas:
Area 1. Methane hydrates on the slope;
Area 2. Methane hydrates on the abyssal plane;
Area 3. Methane hydrates associated with the spreading Gakkel Ridge hydro-thermal activity (the Gakkel Riidge runs in between the northern tip of Greenland and the Laptev Sea).
