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.
