It also occurs in the sea bed of warmer
waters where they are of sufficient
depth to enable it to remain
stable.
A lot of reseach energy is being devoted to the study of Methane Clathrates — a huge source of greenhouse gases which could be released from the ocean if the thermocline (the buoyant
stable layer of warm
water which overlies the near - freezing deep ocean) dropped in
depth considerably (due to GHG warming), or especially if the deep ocean
waters were warmed by very, very extreme changes from the current climate, such that deep
water temperatures no longer hovered within 4C of freezing, but warmed to something like 18C.
The vertical temperature profile may also play a role, as warmer
water is lighter, and thus the stability of the
water column depends on how fast the temperature drops with
depth — more
stable water column is less prone to mixing.
It also occurs in the sea bed of warmer
waters where they are of sufficient
depth to enable it to remain
stable.
Given the
depth of the
water, the relatively small vertical turnover, and the limited outflow (one river), it is surprising (to me) that the temperature at
depth isn't
stable at about 4.0 °C, as it is in most other lakes of reasonable
depth.
However, even in the cold Arctic Ocean, methane hydrate is only
stable below about 200 m
water depth, making for an inefficient pathway to the atmosphere at best.
[9] However, it is also thought that fresh
water used in the pressurization of oil and gas wells in permafrost and along the continental shelves worldwide combines with natural methane to form clathrate at
depth and pressure, since methane hydrates are more
stable in fresh
water than in salt
water.
