NASA Operation IceBridge: From the Cockpit | Arctic Sea Ice + Commentary (2013)

Published on YouTube Aug 23, 2013: You’ve seen the great cockpit footage from Best of IceBridge Arctic ’13, now go behind the scenes for 9 minutes of scientific commentary with Operation IceBridge Project Scientist Michael Studinger and NASA sea ice researcher Nathan Kurtz, as they discuss the science behind the mission’s study of Arctic sea…

Arctic Death Spiral – Evolution to July 2013

Published on YouTube Aug 12, 2013: This is a visualization of the Arctic Death Spiral showing the evolution of the volume of sea-ice over time from 1979 to July 2013. Pitch of the notes are proportional to the average sea-ice volume for each month. Spectral filters are derived from the average sea-ice volume for each…

A Mechanism for Shallow Methane Hydrate Dissociation

I previously looked at the science and commercial usage of Methane Hydrate, at freshwater influx in the Arctic Circle and asked  Does Freshwater Runoff in the Arctic change Ocean Circulation to Unlock Methane Hydrate in the Deep Ocean? This post covers: Identification of possible mechanism which could eventually release vast quantities of shallow Methane Hydrate…

NASA Finds ‘Amazing’ Levels Of Arctic Methane And CO2, Asks ‘Is a Sleeping Climate Giant Stirring in the Arctic?’

By Joe Romm / Climate Progress – on Jun 13, 2013: A NASA science team has observed “amazing and potentially troubling” levels of methane and CO2 from the rapidly warming Arctic. Given the staggering amount of carbon trapped in the permafrost — and the fact that methane is a very potent heat-trapping gas — the…

Does Freshwater Runoff in the Arctic change Ocean Circulation to Unlock Methane Hydrate in the Deep Ocean?

Recently freshwater intake into the Arctic Circle have changed ocean currents, in the following a collection of related science, and what if freshwater currents drive warmer water into the deep ocean and unlock methane hydrates? Mechanism have been identified recently. Arctic freshwater input into the North Pacific could serve as a catalyst for methane hydrate…
