CAS = Central Arctic Sea.  Used by NSIDC.  Which gerontocrat tells us is 3.2 km2 less than the CAB.  JAXA uses CAB right?
Whoops - we are talking about the division of the High Arctic into the 7 central seas
- see attached table & maps.

CAS = Central Arctic Sea.  Used by NSIDC.

Where does NSIDC call it "Central Arctic Sea"?  On their website they call it Central Arctic Basin (or briefly Central Arctic), just like everyone else. 

There are different ways to define the CAB (Wipneus uses a different definition than the NSIDC).  But I see no reason to add some non-existent "CAS" terminology that was made up by gerontocrat.  By that logic, you may as well rename Hudson Bay to Hudson Sea...

   I hear you.  I was just responding to gerontocrat's CAS graphs and trying to clarify "CAS" vs CAB.  But apparently there is no such CAS label, just different definitions for CAB.  So I change that suggestion to a new one -- the glossary should note that CAB has different definitions between NSIDC and others.

Gero maybe you can replace CAS with CAB Central Arctic Basin (and Baffin Sea to Baffin Bay) in your publications? This will help clarify things by sticking to the common names.
I will add a clarification to CAB in the glossary regarding its contentious borders.

   If the ASIF glossary is not limited to acronyms, even though gerontocrat restates the list in his updates, glossary definitions for
Central Arctic Seas (= Chukchi, Beaufort, CAA, East Siberian Sea, Central Arctic Basin, Laptev Sea, Kara Sea)
vs.
Peripheral Arctic Seas (=Okhotsk, Bering, Hudson Bay Baffin  Bay, Gulf of St. Lawernce, Greenland Sea, Barents Sea)
  would be useful to have in the glossary because that is where people are likely to go first when they encounter those terms and are looking for clarification.

    Also worth noting in definition of the CAB that even though the Lincoln Sea is labeled as a separate entity (e.g. NSIDC map), for Extent/Area/Volume stats it is counted as part of the CAB.

Added entries for Peripheral Seas and for High Arctic. Edited CAA entry to include list of main waterways. Edited CAB to include mention of the Lincoln Sea - and the Wandel Sea...

     1st draft glossary entry for "Atlantic Front"  - "An area of what used to be contiguous ice pack between the Fram Strait - Svalbard - Franz Josef Land and the North Pole that fractured into individual floes in 2020-2021."   Feel free to edit.

     1st draft entry for Transpolar Drift - "The predominant pattern of ice movement in the Arctic Ocean from the Russian side across the North Pole and towards the Fram Strait between Greenland and Svalbard.  The speed and direction vary, but this pattern consistently occurs." 
    I'm sure somebody can do better.

     1st draft entry for Beaufort Gyre - "A loosely defined circular pattern of ice movement from the Beaufrot Sea towards the Russian side of the Arctic Ocean and then toward the Central Arctic Basin and ultimately back to Beaufort Sea.  However, whether such a pattern actually exists is a matter of debate as there is neither a persistent nor consistent specific pattern to the ice movement.  Thus some experts dismiss it as making any number of temporary periods fit under a name that is not really an actual entity.  The concept of a Beaufort Gyre is frequently cited as a source for the creation of multiyear ice because the movement would keep the ice in the regions of the Arctic Ocean for many years allowing ice to accumulate thickness from year to year without exiting the Arctic.  The transition of the areas traversed by a hypothetical Beaufort Gyre into areas of summer ice melt is cited as the reason for the demise of multi-year Arctic sea ice."

     I'm really sure somebody can do better that this.

     I think both terms should be in the glossary so that new people coming to the Forum can get up to speed with the terminology bandied about quickly.

Thanks Glen. I will add all these terms to the glossary, but reduce the level of detail to maintain some uniformity. In parallel I have made quite a few edits recently and will continue to somewhat enhance the level of detail in some of the entries.
Also added HYCOM, CDW, AABW, DMI +80N.
