Antarctica / Antarctic Methane Concentrations

« on: February 28, 2013, 03:07:53 PM »

Over the last couple of weeks, higher levels of methane have started to appear over Antarctica.

I have updated the METOP 2/B images through February 26, 2013 pm. They reveal that there is a significant area of high methane concentration over Antarctica.

I have updated the METOP 2/B images through febraury 26, 2013 pm. they reveal that there is high methane release over the Barents and Kara the last few days.

Also there is a significant area of high methane concentration over Antarctica.

Chris and others,

Check out the article on Greenland snow melt during January-February 16, 2013.

Arctic sea ice / Re: Records and oddities

I'm interested in how that released stress affects the rest of the ice pack. Some fractures are extending towards Ellesmere. From the area in the Bering, new fractures have opened almost all the way to Wrangel Is.

Time will tell if we are seeing a larger breakup event, and I have not been watching what the flow out the Fram Strait looks like.

Crandles, Lodger, etc,

Arctic CO2 is already above 400 ppm in 2013.

Barrow, AK:

January, 2010, no readings above 400 ppm
January, 2011, 4 of 16 readings were above 400 ppm, highest was 403 ppm.
January, 2012, approximately 4 readings were above 400 ppm, highest was 405 ppm.
January-Feb 2013, Almost every data point ranged from 400-405 ppm.

http://www.esrl.noaa.gov/gmd/dv/iadv/graph.php?code=BRW&program=ccgg&type=ts

Alert, CA:

January, 2013, one data point available - above 400 ppm.

Ny-Aslund, Svalbard:

January-February 2013: All except one data point above 400 ppm, highest was 403 ppm.

http://www.esrl.noaa.gov/gmd/dv/iadv/graph.php?code=ZEP&program=ccgg&type=ts

Although I am not posting it, the METOP 2 IASI CO2 reveals that much larger areas are above 400 ppm on a daily basis.

It may take a year, but Hawaii will get there.

Chris,

The earliest Beaufort image I saved as February 8. It follows for comparative purposes, A-Team may have something earlier - from January.

Thanks Chris,

The fractures have reached Banks Island....unbelievable!

I have updated the METOP2/B IASI CH4 Google Earth imagery through 22 Feb 2013 pm, and added the IASI imagery through 24 February 2013 pm. No time for more Google Earth till later this week.

https://sites.google.com/site/a4r2013metop2iasich4co2/home/2011-airs-ch4-359-hpa-vs-iasi-ch4-970-600-mb

Here is what the Google Earth imagery shows as of 22 Feb 2013 pm for methane release at 718 mb with concnetrations reading as high as 2145 PPBv.

The AVHRR imagery reveals that much of the remaining Beaufort sea ice shredded between 26 Feb, 2013 1903 and 27 Feb, 2013 0326.

The images are attached for comparison. Also I have posted them at:

https://sites.google.com/site/apocalypse4real/home/arctic-sea-ice-polar-avhrr

The Feb 26-27 images are in the middle column.

Permafrost / Re: What is Happening under a Cloud of Methane?

« on: February 26, 2013, 04:04:35 AM »

Lodger,

What you just postulated above was new to me, and thanks for it. The main problem, with that is that so much of the methane in the Atlantic, Barents, and Kara has been over waters with higher SST's.

Something more sobering to think about.

I have updated the METOP 2 IASI CH4 through Feb 20 2013 pm

There are significant areas of high methane, especially in the Pacific or Inner Mongolia.

Hi Bruce,

Let's keep this thread open for Arctic Methane and start a new thread for hydrogen sulfide.

I have updated the Arctic methane release through Febraury 19 2013 am. There was wide spread release or concentration in the Atlantic, Russia and Norwegian and Kara Seas.

See: https://sites.google.com/site/a4r2013metop2iasich4co2/home/2011-airs-ch4-359-hpa-vs-iasi-ch4-970-600-mb

Let's do radiative forcing under methane cloud.

I have added a compilation of CH4 forcing to my webpage:

https://sites.google.com/site/apocalypse4real/home/2011-airs-ch4-359-hpa-vs-iasi-ch4-970-600-mb

In regard to methane release, I have more imagery to post to the METOP 2, and will get to it over the weekend. I have 2 major projects today for work.

Lodger,

Thanks for the repost.

Also, there is a new report on Arctic Sea Ice decline and impact on green house gasses in the Arctic:

http://www.nature.com/nclimate/journal/vaop/ncurrent/full/nclimate1784.html

According to Dr. Parmentier, in a comment in Decoded Science:

“We have less data available for methane emissions; it is, therefore, more difficult to establish a connection between sea-ice extent and CH4 release. However, it is reasonable to think that, with a smaller sea-ice extent, an increase in CH4 emissions is likely; indeed some modelling studies predict this.”

Old Leatherneck,

We ended up here for similar reasons. The ice was secondary to what was happening with potential methane release, which is why I track it.

I will post here each time I update the METOP 2, Giovanni or other methane imagery to keep you and others up to date.

Artful,

Thanks for the link, I have looked for results and imagery from JAXA with no success. I will have a look this weekend, or when I get snowed in...tomorrow!

Permafrost / Arctic Methane Release

« on: February 17, 2013, 05:01:55 PM »

Welcome to the Arctic Sea Ice Forum - Arctic Methane Topic!

I will post observations and comments on methane release in the Arctic Basin and surrounding seas or land areas on this thread.

There is a website I maintain which tracks methane release for AIRS/AQUA/IASI methane imagery with the kind contribution of Dr. Leonid Yurganov. It is found at:

https://sites.google.com/site/apocalypse4real/home/sea-ice-thickness

I also maintain a set of imagery for METOPS 2 IASI CH4 at this site:
