Three optical sensors were integrated into the Seasonal Ice Mass Balance Buoy (SIMB) 3 to autonomously measure Arctic sea ice mass balance and solar radiation partitioning simultaneously to better understand how Arctic sea ice responds to environmental forces and amplifies climate change. Two pyranometers measure incoming and reflected solar irradiance and an underwater quantum sensor measures PAR and transmitted solar radiation. The optical sensor SIMB-3 was sent to the Beaufort Sea, Alaska, for deployment. Due to complications with Covid-19 and dynamic ice conditions, the device is now scheduled for deployment in spring 2021. The results section presents data from a SIMB-3 that was deployed in the Beaufort Sea in fall 2019 and compares the data with previous Beaufort Sea mass balance sites. Increased observation of the Arctic can help attribute changes in sea ice to environmental forces that are poorly understood.
