Arctic Maps

[magnamentis]

It appears I didn't mention here the Windytv.com website with awesome presentations of wind, temperature, waves, precipitation and pressure forecasts.

has been mentioned and used to post images a few times in the past but it's a such an extremely nice and useful tool that it's certainly good to bring it to more users by regular re-mentioning :-)

Feliz Año :-)

Dragons that once appeared on maps of the Arctic apparently now only live in the Southern Ocean near Australia.

A type of seadragon known only from museum specimens has been seen in the wild for the first time in deep water off Western Australia.

Two ruby seadragons were observed for nearly 30 minutes, uncovering new details about their anatomy, habitat, and behaviour.
 

The researchers from the University of Western Australia, the Western Australian Museum, and Scripps Institution of Oceanography used a mini-remotely operated vehicle in waters more than 50 meters deep near the Recherche Archipelago off Esperance.

Here’s the footage:

Alright, I'm not really convinced early map makers were referencing the same or similar species to these small creatures now known to science.

Cross-posted old map

epiphyte: definitely unprecedented in recorded history.

From one of my articles - http://www.science20.com/chatter_box/arctic_ice_july_2010_update_3_0


The map shows what was considered to be an average minimum, i.e. summer  ice extent in 1939.

[be cause]

I notice pack ice reaches to almost 85' N of Svalbard . Permanent sea ice appears to cover less area than in my old school Atlas from 1975..

So extensive and dangerous a work

    Eleven nations established 14 principal research stations across the Polar Regions. 12 were in the Arctic, along with at least 13 auxilary stations. Over 700 men incurred the dangers of Arctic service to establish and relieve these stations between 1881 and 1884.

Svalbard and Franz Josef Land (FJL)

The Norwegian Svalbard archipelago was known as Spitzbergen before 1925 and includes the island of Spitzbergen.  The Russian military's Franz Josef Land archipelago is also know as Franz Joseph Land and (less often) Franz Josef(ph) Islands.

(Bottom map of both archipelagoes is from a cruse company's PR map)
Svalbard:

A cool map of FJL from an 1894-97 expedition is too big to show as an image.  An FJL sketch map is depicted below.

you can send me the image so i can gonna make it smaller for you if you like, assuming that you're talking about file size not image extent :-) however that as well could be fixed/altered, just in case you're interested.

Thanks, magnamentis.  From above, here is the "cool map of FJL from an 1894-97 expedition is too big to show as an image."  Click for enlarged, and much better looking, version.

This isn't an Arctic map, but some may find this cross-post helpful:

There is a mix of ice shelfs here: Only the first picture shows the Shackelton Ice Shelf, the others show the West Ice Shelf where a large ice berg is finally breaking apart after staying put for at least 25 years.

All of the above images show the Shackleton ice shelf.  The West ice shelf lies between Amery and Shackleton and is not shown above.  Please see the image below.

The ice island in Shackleton is sometimes known as Pobeda ice island: it is mentioned in my article The Amery Zig-Zags.

couple of interesting links, the first shows bathymetry worldwide reasonably well, but with too little detail for the shelves, the second is one of a series of 16 gives a slightly improved veiw but again lacks detail, and stops at 75⁰ N/S

Has the limestone gone dolomitic? Memories of breaking my hands and heart breaking up some of it in the Forest of Dean, England.
ps: These old maps are wonderful, made by true Mariner Masters.

[Tor Bejnar]

A much better map than what I created June 15, 2015 (above)!

Mind you, by an ironic conincidence, "less than 1 million km2 of ice extent"  is almost exactly 15% of the average 1990s summer minimum...

Ha, I was wondering about that. Thanks, Peter. [...]

I like to say 'ice-free for all practical purposes', after hearing Walt Meier putting it like that once.

Someone has almost certainly already done this, but I don't know where, so I re-invented this wheel...

Here's a map showing what 1.0 million, 0.5 million, and 0.1 million km2 of ice extent could look like.  It's based on the grid cells with the maximum concentration in NSIDC September maps for the years 2008-2016.  My assumption is that ice will last longest in grid cells where Sept concentration is consistently the highest over the past decade.

[edit:  see map below]

If someone knows of a better version of this analysis here or elsewhere, please let me know!

Looking at the map, I'd say that 1 million km2 is actually a bit high for an "ice-free" threshold, personally.

I don't recall posting a link to the sister thread Sea Level Rise Projections and Maps that is in the "AGW in general - Consequences" section.  (There are precious few references to the Arctic in that thread, and no actually maps of the Arctic posted there.)

[Tor Bejnar]

Real maps!  Cross post from What's new in Greenland? thread.  I particularly value the map on the right that shows where glaciers have 'deep water ports' and are therefore most likely to suffer from warm ocean water melting their undersides.  The Petermann Glacier's fjord's depth was (more or less) known to me.  Of interest is Jakobshavn Glacier's deep connection to the interior.  Then there is the 3rd 'direct access' to the interior via Kane Basin and Humboldt Glacier.

https://www.nasa.gov/feature/jpl/new-greenland-maps-show-more-glaciers-at-risk

'New maps of Greenland’s coastal seafloor and bedrock beneath its massive ice sheet show that two to four times as many coastal glaciers are at risk of accelerated melting as previously thought.'

Sigh.

So is this the largest freshwater "lake" in the world - by far

Title: "New map reveals landscape beneath Greenland's ice sheet"

https://phys.org/news/2017-12-reveals-landscape-beneath-greenland-ice.html

I wonder what is the relationship between the "new Greenland map" Adam Ash reported on above (November 7) and this one ["published this week (Thursday 14 December 2017)"].

From November 7 linked article:

Researchers at the University of California at Irvine (UCI), NASA and 30 other institutions have published the most comprehensive, accurate and high-resolution relief maps ever made of Greenland's bedrock and coastal seafloor. Among the many data sources incorporated into the new maps are data from NASA's Ocean Melting Greenland (OMG) campaign.

From today's linked article:

Produced by researchers at British Antarctic Survey (BAS), University of Bristol and University of California at Irvine (UCI), the printed map is unveiled this week at the American Geophysical Union meeting in New Orleans.

"Greenland Basal Topography BedMachine v3" is the new 1:3,500,000 scale map created from data collected by over 30 institutions.

The Boundaries of the Arctic Ocean Seas.

I looked for a definitive map of the Arctic Ocean with the boundaries marked in three ways - those used by the NSIDC for their regional extent and area spreadsheets, and the political boundaries.

I did not do very well.  I attach examples

Any idea where I can find them?

[Edit: Note: the following map on the NSIDC site is interactive: each region is selectable.]

I think this is the NSIDC regions map.

Slightly OT but interesting:
Greenland’s Hand-Sized Wooden Maps Were Used for Storytelling, Not Navigation
<snip>

On February 8, 1885, a hunter named Kunit approached Holm (Danish explorer) with a driftwood carving he had made—a representation of unbroken coastline that could be flipped around as one followed the contours of the coast. “[Kunit] had carved the chart himself and declared that it was not unusual to make such charts when one wanted to tell others about regions they did not know,” Holm wrote. The hunter produced three maps in total, now collectively referred to as the “Ammassalik maps.”

One carving, 5.5 inches in length, is highly detailed, embedded with all sorts of information and place names for the fjords above and beyond the 65th parallel. It even indicates locations where a traveler would need to carry his kayak overland to get to the next fjord. Another carving measures a little over 8.5 inches long and depicts a specific chain of islands along the coast, connected by narrow stems. These two maps could be placed next to one another to demonstrate the relative positions of the islands along the coast. A third, smaller map was also commissioned by Holm and shows the fjords stretching from Sermiligaaq to Kangerlussuatsiaq and includes valleys, shores, and inlets farther inland. Holm never actually traveled through the regions represented by the maps, but they helped him get a larger understanding of the local geography.

Thank you Anne.  The article was fascinating. And maps are maps, so it wasn't 'off topic'!

I agree - maps is maps and always useful. So here are three more that I found useful when considering topics such as snow cover, effects of June river flows etc etc.

One of my favourite resources for whole Arctic maps is the ECM, it gives some really nice theoretical maps based on global temperature changes

This doesn't do a northern hemisphere projection, but it does allow for checking height/depth of features. Frinstance the depth of the hot-spot delivery trough

Lots of stuff on the melting season thread on the Canadian Archipelago. Here is a political map with at least some of the names on.

[litesong]

DeLorme(now owned by Garmin) highway maps are "books" of maps of the states of the U.S. The representation of Alaska is  a 156 page real book, with the highest detailed sector maps giving a stunning lifetime study of Alaska. Unfortunately for this website's followers, northern & western representation maps (including Alaskan lands bordering the Bering Sea, above the Arctic Circle line & Aleution Islands) are at a lower presentation of detail (still good,tho) & no sea ice conditions are included. However, the high detailed south & eastern sector maps, including shorelines & interior, do have glacier extents (hopefully accurate).  I have a 1998 version (gotten at garage sale) that I love. An up-dated Delorme Alaskan map is available, & would give interesting physical terrain detail differences to the original, if such be the case.

PS:

weather.us has direct day-to-day comparisons now for very many variables! Unfortunately the data only goes back to 2017, but here is the year over year for snow depth.



You can toggle back and forth for many other variables as well (SWE, water temp, sea ice, pretty much anything).

Go here and input whatever you want, just change region / timestamp etc:

https://weather.us/model-charts/euro/massachusetts/gusts-3h-mph/20171030-0600z.html

The ^ data is from the EURO. On that note, it is interesting that EURO is the only model where water temps and sea ice appear to be un-static, perhaps explaining one of the reasons why it is so much more accurate than the GFS / CMC, both of which lack these options for toggling (and whose consistently terrible output leads me to believe they do not incorporate it beyond 00z hr data as well).

Thanks for the resource, BBR

Not sure where this should go - but worth noting - looks like the Magnetic North Pole is sliding away from Canada / USA towards Russia.

I don't think this a DCMarvels superhero style achievement by some dastardly scientist / politician.....

"OSLO (Reuters) - Rapid shifts in the Earth’s north magnetic pole are forcing researchers to make an unprecedented early update to a model that helps navigation by ships, planes and submarines in the Arctic, scientists said.   
Compass needles point towards the north magnetic pole, a point which has crept unpredictably from the coast of northern Canada a century ago to the middle of the Arctic Ocean, moving towards Russia....... "

Hmmm.  I clicked on "Wikipedia map" and got a black X in a square instead of a map.  The map is at https://upload.wikimedia.org/wikipedia/commons/e/ee/Operational_Navigation_Chart_A-5%2C_3rd_edition.jpg

I was looking for a map with place names for the north-northwest corner of Greenland and came upon this detailed Wikipedia map.  It appears to not include places like Oodaaq/Oodaap Qeqertaa (which may not exist any more) but looks very useful.  I also found a Mapcarta map, but place names don't exactly match locations!

Does Espen have an opinion?

Go to the map and look at it enlarged.  (Screen prints are at 25% and 400%, just for a taste.)

Hello Tor the 2 islands you are asking for are found in some few maps like this one from GEUS the northernmost of the "islands" (sand gravel) is located at 83.40 where as Kap Morris Jesup is at 83.39 see attachment
