SESS report 2021

The State of Environmental Science in Svalbard (SESS) report 2021 has been released during the SIOS Polar Night Week in Longyearbyen, 24 January 2021. It is the fourth issue of an annual series of reports published by SIOS.

In the three first years of the SESS report, SIOS has received more than 140 recommendations on how to improve the observing system for Earth system science in Svalbard. In 2021 it was time to consolidate and implement these recommendations. Therefore, the SESS report 2021 is the first report focusing on chapters already published in previous SESS reports.

The SESS report is published in two versions:
