The COVID-19 (coronavirus disease) pandemic spread has virtually paralyzed daily life, and the world is facing huge challenges getting back to normal. The study also demonstrates the relevance of satellite radar observations in coastal areas with severe cloud cover, such as the one evaluated here.
This fact has relevant repercussions for the population living in isolated areas, such as many places in Patagonia, including Tierra del Fuego. The results demonstrate that the total maritime traffic activity in the three geographical hotspots selected along western Patagonia, the Chacao Channel, crossing of the Reloncavi Fjord and the Strait of Magellan was totally interrupted during April–May 2020. The spatial information is analyzed using the Google Earth Engine (GEE) platform as a global geographical information system and the EO Browser tool, integrated with several satellite data. For this goal, three locations are observed using geoinformatic techniques and high-resolution satellite data from the Sentinel-1 satellites of the European Commission’s Copernicus programme. The purpose of this research is to describe this interruption of navigation using satellite synthetic aperture radar data. Maritime navigation has been affected in strategic connections between some regions in Patagonia, at the southern end of South America. Human mobilization during the COVID-19 lockdown has been reduced in many areas of the world.
