Pelagic ecosystem dynamics between late autumn and the post spring bloom in a sub-Arctic fjord

Marine ecosystems, and particularly fjords, are experiencing an increasing level of human activity on a year-round
basis, including the poorly studied winter period. To improve the knowledge base for environmentally
sustainable management in all seasons, this study provides hydrographic, and biological baseline data for the
sub-Arctic fjord Kaldfjorden, Northern Norway (69.7 N, 18.7 E), between autumn 2017 and spring 2018.
