Most people following climate change know that Arctic sea ice AREA (region with all ice, no open water), EXTENT (-15% ice), and THICKNESS are dropping like a rock. 

Here I discuss AGU 2017 talks on how less known ice properties (strength, wetness, age, density, cohesiveness, motion, salinity, etc.) are changing; and also how satellite instruments detect these properties; and which limitations exist, fo example ice -30 cm thick and salt content measurements are problematic.
