Cover Story: The COVID-19 pandemic has impacted polar research in many ways since the start of 2020, including cancellation of field campaigns, cancellation and/or postponement of important conferences, workshops, and training courses, delays in delivery of scientific outputs because of shutdown of campuses, cancellations and/or delay in funding and many more. Further, field campaigns to Svalbard are expected to remain severely affected in 2021. In response to the changing situation, SIOS initiated several operational activities suitable to mitigate new challenges resulting from the pandemic. The paper provides an extensive overview of EO, RS and other operational activities developed in response to COVID-19. It is probably the first attempt to highlight the role of EO and RS in mitigating the damage in terms of possible data gaps in long time data series of scientific observations in one of the most remote places on planet Earth.View this paper
