Science - Environment & Ecology / Different types of snow, one is missing
German term or phrase: Schwimmschnee
Es bilden sich Kristalle, die in einer Schicht von *Schwimmschnee* oder *Tiefenreif* angereichert sind.

Jetzt weiß ich schon jede Menge über Schnee, Kristalle und deren Tragfähigkeit. Allerdings ist mir die Übersetzung von *Schwimmschnee* absolut unbekannt. Auch durch Suchen konnte ich nichts finden.

(Für Tiefenreif habe ich schon jede Menge Varianten)

Hilfe wäre nett.

rotten snow
Explanation:
der Tiefenreif • depth hoar (der Tiefenreif). Consider also: temperature gradient snow (der Schwimmschnee), rotten snow (der Schwimmschnee). ...

Depth hoar otherwise known as rotten snow is a deadly weak layer. Getting stuck a lot is a good sign that the snowpack may be unstable.

http://www.fsavalanche.org/Default.aspx?ContentId=13&LinkId=...

Depth hoar: Imagine you're a snowflake near the ground. The Earth warms you up, and you start to sweat. (Okay, okay... it's not sweat, but you do pump water vapor into the air spaces between your lovely, fluffy crystals.) This vapor migrates to colder snowflakes and recrystallizes. They get larger, but weaker, and the result is a layer of elaborate but weakly bonded crystals called "depth hoar."

agree  philgoddard: You beat me to it with "depth hoar", but I'll leave my answer up as it contains a couple more references.

  -> Looks like they're synonyms. Just another word for the same thing as in the ST.

sugar snow


Explanation:
I think sugar snow describes what you are talking about, but am not certain this is identical to Schwimschnee.

See: http://factsanddetails.com/china.php?itemid=196&catid=6&subc...
"Avalanches usually occur when a layer of snow called "sugar snow" (snow that doesn't bond well with other snow) cannot support the weight of additional snow and collapses, causing the top layers of snow to slide. Sugar snow is produced when water vapor condenses, forming loosely bonded crystals, when the temperature difference with the snowpack exceed 10°C per meter. "

depth hoar


Explanation:
It means the same as Tiefenreif, and also translates as "coarse-grained snow".

Example sentence(s):
  • Coarse-grained snow (a.k.a. “depth hoar” or “Schwimmschnee”) is then formed. Coarse-grained snow comprises large grains with loose connection between one another.
  • Often, the combined weight of snow and people walking on a snowpack with an internal weak layer such as depth hoar (German: Schwimmschnee) or light density snow will cause the weakness to collapse

Asker: I am not sure but I think it´s like a "special" version of fresh snow. The often adevrtised powder snow (which you can find in marketing texts also as like being champaign powder or so).
