Research during the quarantine
“I began valuing my personal relationships more during the pandemic”
Oceanographic research is heavily dependent on fieldwork and, to a large extent, on laboratory and on-board work. In March, with the prospect of a lockdown looming on the horizon, activities at USP [University of São Paulo] were suspended, as well as our field trips. This was the main impact of the pandemic on my work... View Article
