Name: SIMB3 2024J — sea ice deployment data
Creator: Cryosphere Innovation

First Year, saline ice on the surface at the exact deployment location, but there is a clearly multiyear hummock 20 ft away, so this is at least in some way MYI. Deep snow prevents really determining the nature of the floe more broadly. Seems likely we deployed in a melted thru pond or in a FYI component of a conglomerate ice floe. Quickly drilling other places on the floe, aside from the obvious hummock, yields similar ice thickness, so if MY, the floe appears to have barely survived summer

Cryosphere Innovation Seasonal Ice Mass Balance Buoy (Version ARCSIX Standard). Buoy has an elongated hull, an Apogee albedometer, a one-part embedded digital temperature string on the upper section.

SIMB3 2024J

Configuration for standard variant ARCSIX SIMB3 (no SnowTATOS).

Bosch BME280 combination pressure, temperature and humidity sensor.

DS18B20 air temperature sensor located at the top of the buoy surounded by a radiation shield. Located approximately 1.2 meters above the ice surface.

Upward looking Apogee pyranometer mounted approximately 1.2 m above the ice

Downward looking Apogee pyranometer mounted approximately 1.2 m above the ice
