There was a general agreement is yesterday’s Sem Tech session that we would

use this as a hackathon-style effort and focus this harmonization session
on the mapping of Cryo

terms to EnvO (and SWEET). We had been matching more things up with SWEET
and ticketing issues.

See the Cryohackathon spreadsheet
<https://docs.google.com/spreadsheets/d/1XmqB5F1SKLZ3y-PIVdQByU3Eho4cHAnUUafko3JNtn0/edit#gid=1512660924>
for the terminologies.

Example:

periglaciation

proglacial

subglacial

supraglacial



depth hoar

frost

granular ice

hoar crystal

ice

ice crystal



As context some notes from our May session on terms.


May 13th Meeting (before our focus on the 5 pager and the ESIP Summer
session)

…..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.

that
America’s cult of individualism was perilously close to raw selfishness —
the “me first” instinct we often see today.

“Individualism, at first, only saps the virtue of public life, but, in the
long run, it attacks and destroys all others, and is at length absorbed in
downright selfishness” — a strait that he warned “blights the germ of all
virtue.”
