Arctic sea ice / Re: What the Buoys are telling
« on: May 06, 2018, 07:49:12 PM »
Just came across this - a small update on O-Buoy 14
"Hunters found OB-14 near Gates Head island in the west Victoria Straits while Polar Bear hunting recently (March 2018)"
There is a picture at the link - http://www.o-buoy.org/

Arctic sea ice / Re: January Poll: JAXA Maximum
« on: January 15, 2018, 06:47:53 PM »
I think (guess  :) ) it will stay under 14 million, so down a bin to 13.75 - 14

Neven - fortunately I saved the link the last time JAXA changed to ADS and they seem to follow the same pattern for the new site, otherwise I don't think I would have found it :-)

Arctic sea ice / Re: ADS-IJIS 2016 Arctic SIE September minimum: July poll
« on: July 09, 2016, 08:03:17 AM »
Just shifted my vote/guess up a bin to 3.75-4.0 from last time - probably still too low, just have to wait and see :-)

Arctic sea ice / Re: Poll: When will there be open water at the North Pole?
« on: May 26, 2016, 10:30:32 PM »
I voted for 2017, mostly because of all the FYI currently close to the pole and assuming (not a good thing to do for the Arctic sea ice) 2017 will be similar if not worse.  Almost picked 2016, but despite the FYI, don't think it is likely.

Antarctica / Re: What's new in Antarctica ?
« on: February 02, 2016, 08:28:49 PM »
An interesting project to get more info on Antarctic ice shelves http://polarfever.com/2016/02/02/physical-oceanographers-on-ice/

Summary -
 The phase sensitive radars were developed and built at the British Antarctic Survey (BAS) and very precisely measure changes in ice thickness. This means that we get a direct measurement of the ice shelf melt rate. Satellites can also be used to measure this, but will only give average values over several years, while we will get a value every 2 hours from the phase sensitive radars. In combination with the moorings that we have deployed at the ice shelf front, this will allow us to directly link changes in ocean temperature to changes in the ice shelf melt rate. The aim of the seismic surveys is to find out how much seawater there is between the floating ice shelf and the bedrock.

Greenland and Arctic Circle / Re: The Nares Strait thread
« on: September 04, 2015, 12:42:24 AM »
Some interesting observations from the Oden as it headed back down the Nares Strait -
"The irony of all of this is that the big icebergs and floes streaming southward out of the Arctic Ocean and blocking the strait may be an indicator of Arctic warming. Although icebergs are not unknown here, those who have been on past expeditions did not report so many. Normally they tend to stay put up in the Arctic, but we think maybe the ice there has loosened up enough that the bergs are free to drift southward. We are not sure of this; will have to check satellite images and commentaries from ice tracking programs when we get home."

This is not the Healy,  but an interesting blog from another research ship - https://scripps.ucsd.edu/projects/arcticmix/ in the Chukchi and Beaufort sea - scroll down to see the "We're Rolling" video which shows some pretty heavy seas as they transited the Chukchi.

Another nice animation - thanks!!  It also looks like some ice from the Lincoln Sea is making its way south thru the Nares Strait

Arctic sea ice / Re: NSIDC 2015 Arctic SIE September minimum: August poll
« on: August 12, 2015, 08:09:07 PM »
Just moved my vote down a bin to 4.25-4.5 - thinking it will be closer to 4.5, but might, depending on weather/compaction, be closer to the 4.25.  Totally unscientific most based on watching the Uni Bremen maps :)

Those images are wonderful and nice to hear from Andreas, especially since he is obviously super busy.
While poking around the Petermann expedition site, I came across this set of updates (https://petermannsglacialhistory.wordpress.com/updates-from-co-chief-scientist-alan-mix/ ) from the Co-Chief scientist and found them very interesting.

Looks like the Canadian portion of GEOTRACES on the Amundsen is back in action again (http://blogs.ubc.ca/geotraces2015/ ) after the diversion to break ice in Hudson Bay.  But like all expeditions, they are experiencing challenges, at the moment from equipment and not the weather or ice.

Greenland and Arctic Circle / Re: Petermann Gletscher / Petermann Fjord / North West Greenland
« on: August 07, 2015, 08:33:43 AM »
From this blog post - http://polar.se/blogg/mammal-observations-hall-land/ it is possible that some of the photos of the land might be Hall Land - I don't know where exactly that is, but other Greenland experts on the forum can perhaps locate it.  My understanding is that the land teams were delivered to their research locations via helicopter, so perhaps they are "in the vicinity" of Petermann

Here is a link to a nice blog post by Céline Heuzé - http://polarfever.com/2015/08/05/sea-ice-vs-glacier/ . She is on board the Oden.  There are some great pictures of the sea ice they have encountered as well as a picture of the face of Petermann

If you go to http://obuoy.datatransport.org/monitor#buoy9/movie and put the movie all the way at the end (drag the bar at the bottom of the image), at the top will be the lat/lon info.  Hope this helps

I am sticking with my 4.5-4.75 bin from last poll - but I may change to a lower amount before the poll closes.  Still watching to see what the next couple of weeks brings for the Beaufort and whether things pick up on the Atlantic side.

Greenland and Arctic Circle / Re: what's new in Greenland ?
« on: July 29, 2015, 11:59:35 PM »
This project - http://www.nature.com/news/nasa-launches-mission-to-greenland-1.18085?WT.mc_id=TWT_NatureNews sounds interesting and should produce some interesting data. 
Excerpt:
"Called Oceans Melting Greenland (OMG), the US$30-million NASA project will help scientists to predict the future of the Greenland ice sheet, which holds enough water to boost sea levels by around 6 metres and already seems to be melting more rapidly in response to increasing air temperatures. But it is not clear how much the oceans affect the rate of melting along the island’s edges, which depends on poorly known variables such as how warm, saline water interacts with the glaciers."

Up a bin to 4.5-4.75 - Beaufort still looks "slushy" and might be a surprise, but everywhere else seems to me to be slow.  Guess we will see what happens this month :)

While the weather currently is pretty overcast in Churchill, this http://www.portofchurchill.ca/port-media/live-feed shows some melting, as opposed to a couple of weeks ago when everything was uniformly frozen.

According this post on Climate Crocks - http://climatecrocks.com/2015/04/24/will-the-chilean-volcano-be-big-enough-to-cool-2015/#more-23560 (fixed link) Calbuco probably won't have much of a cooling effect.

Anreas Muenchow has an interesting new post on Petermann over at his blog - http://icyseas.org/2015/02/08/lab-notes-of-a-physical-oceanographer/ - he is hoping to install some instruments on Petermann this summer - hoping to crowdfund this project (see https://experiment.com/projects/ocean-warming-under-a-greenland-glacier )

I think Andreas Munchow is currently on the Polarstern headed to this area (http://icyseas.org/2014/04/14/north-greenland-glacier-ice-ocean-interactions-2014/ ) so perhaps there will be some more information and studies of this area soon.

Arctic sea ice / Re: What the Buoys are telling
« on: June 03, 2014, 12:09:11 AM »
I would say footprints (polar bear most likely  :) ) and definitely looks like open water especially on today's image just coming in - nice and sunny too.  Webcam #1 on its side http://psc.apl.washington.edu/northpole/NPEO2014/9.jpg , while not as interesting, gives a good view of melting ice.

Arctic sea ice / Re: NSIDC 2014 Arctic SIE September minimum: June poll
« on: June 01, 2014, 09:17:54 PM »
At this point in time I am being much more "conservative" than last year and ticked the 4.5-4.75 box.  That said, I expect June to be a telling month for where the extent will finally end up.  Ice seems very fractured and weak to me (eyeball observations of MODIS), but hard to say if that will equate to a big melt - will wait and see how the June weather turns out.

« on: May 05, 2014, 09:21:31 PM »
They are within 19 miles of the pole and finding really bad ice conditions - lots of leads, only small ice floes, needing to swim leads or worse, unexpectedly falling thru the ice - these last few miles may be the most difficult ones.

45
Arctic background / Re: Eric Larsen's "Save The Poles" Expedition
« on: May 04, 2014, 01:44:54 AM »
This expedition is closing in on the pole - latest position Latitude: 89.273, Longitude: -41.19 | Dist To Pole: 50.3 Miles.  After a couple of days of good ice, clear weather and not a lot of drift, they are now struggling with flat light and more drift.  They also report polar bear tracks on the same path they are on - an additional worry.  Hopefully the polar bear finds a nice tasty seal to snack on and won't be interested in them.

After getting a resupply and a relocation to the west via airplane (they had drifted about 142 km to the east), Expedition Hope is at 85deg 14min N, 79def 18min W and battling lots of pressure ridges and big leads.

Very interesting expedition to follow. 
There is another expedition led by Eric Larsen (Save the Poles)  http://www.savethepoles.com/updates/]  [url]http://www.savethepoles.com/updates/ [/url] -  that is going from Canada to the Pole - opposite direction to Expedition Hope.  Interesting to read the blog and see the ice conditions they are encountering.
