HETEROGENEOUS ICE NUCLEATION IN SUPERCOOLED MICRO-ARTHROPODS.

Author(s) : BLOCK W.

Type of article: Article

Summary

THE PROBABILITY OF FREEZING INCREASED EXPONENTIALLY WITH LOWERED TEMPERATURE FOR SEVEN SPECIES OF ANTARCTIC ARTHROPODS. SLOPES OF FITTED REGRESSIONS WERE SIMILAR FOR MOST SPECIES AT TWO LOCATIONS. LOW TEMPERATURE ACCLIMATION MOVED THE REGRESSION LINE SIGNIFICANTLY DOWNWARDS, BUT THE SLOPE REMAINED UNCHANGED. INDIVIDUAL ARTHROPODS BEHAVED IN A SIMILAR FASHION TO WATER DROPLETS WHEN SUPERCOOLED AT 0.5 TO 1.0 DEG/MIN, BUT NEITHER STOCHASTIC NOR SINGULAR MODELS FOR HETEROGENEOUS NUCLEATION APPEAR ADEQUATE.
