Replication data for: Subglacial upwelling in spring increases under-ice primary production
The dataset was taken in April 2019 in Billefjorden, Svalbard, a sea-ice covered tidewater glacier influenced fjord. The aim of the study is to investigate the effect of potential subglacial upwelling on oceanographic and biogeochemical processes in the fjord. We hypothesized that subglacial upwelli...
