Abstract. The Green Edge project was designed to investigate the onset,
life, and fate of a phytoplankton spring bloom (PSB) in the Arctic Ocean.
The lengthening of the ice-free period and the warming of seawater, amongst
other factors, have induced major changes in Arctic Ocean biology over the
last decades. Because the PSB is at the base of the Arctic Ocean food chain,
it is crucial to understand how changes in the Arctic environment will
affect it. Green Edge was a large multidisciplinary, collaborative project
bringing researchers and technicians from 28 different institutions in seven
countries together, aiming at understanding these changes and their impacts
on the future. The fieldwork for the Green Edge project took place over
two years (2015 and 2016) and was carried out from both an ice camp and a
research vessel in Baffin Bay, in the Canadian Arctic. This paper describes
the sampling strategy and the dataset obtained from the research cruise,
which took place aboard the Canadian Coast Guard ship (CCGS) Amundsen in late
spring and early summer 2016. The sampling strategy was designed around the
repetitive, perpendicular crossing of the marginal ice zone (MIZ), using not
only ship-based station discrete sampling but also high-resolution
measurements from autonomous platforms (Gliders, BGC-Argo
floats …) and under-way monitoring systems. The dataset is
available at https://doi.org/10.17882/86417 (Bruyant et al., 2022).
