I may be a bit late to today’s meeting as I’m taking my dog to the  vet.

>> periglaciation
>> proglacial
>> subglacial
>> supraglacial
>> 
>> 
>> depth hoar
>> frost
>> granular ice
>> hoar crystal
>> ice
>> ice crystal

>> 
>> …..harmonizing EnvO and SWEET (along the semantic gradient) not solving all of SWEET’s issues.
>>               SWEET  “glaciation” maps to EnvO “glacial ice gain”.
>> Ruth notes that glaciations as time periods are named (e.g. Pleistocene).
>> 
>> 
>> Chuck geo-schema (with OWL-Time) might provide a cross walk for the 2 ontologies looking at geo-time periods.
>> 
>> 
>> Work included editing Chuck’s owl file such as deprecating “periglaciation”.
>> 
>> 
>> Getting back to harmonizing EnvO and SWEET (is this a 2 step process? If we add the terms to SWEET, clean them up AND then see how to map to EnvO.) :
>> Issue #185 - definition of “glaciation”. Involves meaning of “glacial” and its sub-properties. Ruth notes 3 different meanings of glaciation in GCW depending on the discipline. So 3 sub-types of Glacial Process?
>> For example difference noted of glaciers advancing to cover land, vs. “glacial ice gain” (mass).
>> 
>> 
>> Issue 190: related to Issue 185. Will be resolved in the quality section of EnvO/PATO.
>> 
>> 
>> Glacial retreat (Maybe also Glacial Advance).  May now be more of a non-issue for alignment but is a SWEET issue - is it a sub-class of “melting”. Probably not.
>> Issue 185: shows the need to revise the whole branch area in SWEET.
>> 
>> 
>> Environmental zone discussion- some distinctions made by NEON about named entity/ sampling sites.  They may have fiat boundaries rather than boundary from a physical process.
>> Q:  Does an ablation zone have to be Part-Of a glacier...or is it overlapping? This hasn’t been answered by the Cryo community.  To some iit can be elsewhere such as on an ice sheet.
>> So EnvO might have an “ice ablation zone” as well as the more general “ ablation zone”.
>> Some discussion of geo-relations in BFO rather than Egenhofer relations.
>> 
>> 
>> Issue: Alpine - resolved exact match issue and noted issue in SWEET about tundra concept.
