A couple of maps naming the islands of the Canadian Archipelago

And or those who like things on paper, a new map about Greenland and a lot more.

Quote

The seasonal sea-ice is in long-term decline and the ice sheet that sits atop Greenland is losing mass at a rate of about 280 billion tonnes a year.

So, if you choose to make a map of the region, you start from the recognition that what you're producing can only be a snapshot that will need to be updated in the relatively near future.

Laura Gerrish, a geographical information systems and mapping specialist at the British Antarctic Survey (BAS), knows this. Polar science and polar cartography are all about tracing change.

Laura has just finished making a exquisite new printed sheet map (1:4,000,000) of Greenland.

The detail is a delight - from the winding path of all the fjords and inlets, to the precise positioning of current ice margins, and the use of all those tongue-twisting Greenlandic names.
The Greenland and the European Arctic map is available for sale as either a flat wall map or a folded map at several outlets, including the Scott Polar Research Institute and Stanfords map store in London.

The match if Pacific salinity with melting patterns in the Chukchi Sea etc is also pretty neat - you can even see the baby elephants trunk along the Chukotka coast
I need a better resolution bathymetry map. The noaa map doesn't have the ~30m trough west of wrangel shown on mercator. Does anyone have one? Complete arctic ocean.
edit: please post in maps thread here https://forum.arctic-sea-ice.net/index.php/topic,417.0.html

Does this work? This is published by NOAA. (so maybe not) Any way, here goes:

Tor Bejnar · « **Reply #107 on:** July 22, 2019, 06:23:58 PM »

Just having a look at the East Siberian Sea (ESS) bathymetry from ARCGIS. These two images are 'big' so that the 10m, 25m and 50m contours show, as well as much of the width of the ESS. The first image includes Wrangle Island and a spot of Siberia. The second shows part of the New Siberian Islands WNW of the Lena Delta and much of the ESS's width. Roughly speaking, it looks like the ESS is about half over 25m deep, and mostly under 50m. (click for full size if you want) The two areas are not adjacent.

Hmmm: the scale is in "mi" = miles. Is the depth feet, fathoms, meters?

? Depth is in meters.

uniquorn · « **Reply #108 on:** July 22, 2019, 06:55:22 PM »

Thanks. ess has very few features by the look of it, just gradual slope. That doesn't even show at all on the noaa bathy (unless I'm doing something wrong)

uniquorn · « **Reply #109 on:** July 22, 2019, 07:12:44 PM »

here's my contribution from noaa. If you look carefully you can probably see the joins. If anyone knows how to show 34m contour let me know

johnm33 · « **Reply #110 on:** July 22, 2019, 08:31:38 PM »

It will zoom in a little more, try options bathymetry-contours, it doesn't always load fully, maybe once in three tries I'll get the full map with contours etc.

It'll zoom in a little more but that's it as far as detail goes, what is handy is bottom left tells you the depth at any point.

mitch · « **Reply #112 on:** July 22, 2019, 08:37:03 PM »

When you refer to the "NOAA map" are you refering to the International Bathymetric Chart of the Arctic Ocean?:
https://www.ngdc.noaa.gov/mgg/bathymetry/arctic/arctic.html

The biggest problem in the Arctic is lack of data. This is especially true on the shelf areas, because one needs to run a close grid of ship soundings to improve the map. The version 3 of this map now has a 500 m pixel.

uniquorn · « **Reply #113 on:** July 22, 2019, 09:07:57 PM »

Thanks again everyone.
johnm33, I occasionally get incomplete contours, so I suppose I will try again, although if I zoom in that far it will be tricky to patch all the images together.
mitch, I've seen the letter sized map, I was hoping for something larger. Though it is pretty good when zoomed using acrobat. I'll try patching that together too.

I tried heavy contrast on the previous compilation and surprise, the contours are there. They are nearly all the same colour though. Here is the heavy contrast version, which satisfies me for now.

Thanks for this. As the CAA is currently melting rather fast,many of these place names are being mentioned, and many of us are pretty fuzzy about where they are.

Thanks so much, Ossifrage! I knew you mentioned waterways not on the map I found, and looking them up and adding them was beyond my time-availability. I like that your map also includes the several towns in the region (readable when the map is clicked/enlarged). Also, when the map is opened in its own (computer screen) window, I can see the map and legend at the same time.

Thanks for posting that, El Cid,

Awesome is the word. I guess they had to use a lot of old ships logs for sightings of the ice edge. I was told a long time ago that in the days of sail there was a 15% rule of thumb. Ships were advised to retreat if they felt there was more than 15% ice cover to avoid the risk of being trapped- which makes sense if you haven't got an engine with which to beat a hasty retreat.
