Abstract
For each station, we profiled an instrumented cage from the surface to 120 m (bottom depth ≈ 200 m).
The cage was equipped with a bathyphotometer (UBAT–Underwater Bioluminescence Assessment Tool, WetLabs, Philomath, OR) and CTD (SBE 49 FastCAT, Sea-Bird, Bellevue, WA).
For each cast, we held instruments for 4 min at every 20 m depth interval to measure bioluminescence.
Fjord sampling in January 2014 (A2014, B2014, C2014, D2014) was conducted in Kongsfjord, Svalbard (78° 56.16'N, 11° 56.58'E). For more detail on this data collection see: Cronin et al. (2016) Scientific Reports 6:36374, DOI: 10.1038/srep36374
Fjord sampling in January 2017 (A2017) was conducted in Rijpfjorden, Svalbard (80° 18.261'N / 02° 215.705'E). For more detail on this data collection see: Shulman et al. (2020) Ocean Dynamics 70:1211–1223, https://doi.org/10.1007/s10236-020-01392-2
Shelf/slope sampling in January 2017 (B2017, C2017) was conducted offshore from Rijpfjorden, Svalbard (80° 55.364'N / 017°32.469E, 80°35.923'N / 013°40.636'E). For more detail on this data collection see: Shulman et al. (2020) Ocean Dynamics 70:1211–1223, https://doi.org/10.1007/s10236-020-01392-2
Arctic basin sampling in January 2017 (D2017) was conducted further offshore of Rijpfjorden, Svalbard (81°21.285'N / 014°51.079'E). For more detail on this data collection see: Shulman et al. (2020) Ocean Dynamics 70:1211–1223, https://doi.org/10.1007/s10236-020-01392-2

Description
The three .m files, and two .asc files can be used to re-create Figures 2, 3, and 4 in the Shulman et al. manuscript:
Figure 2: "plot.Figure02.m" is a Matlab m file that calls data from two .asc files ("PNC17_v2_R3and NS6.asc" and "PNC17_stopPoints.asc") to re-create the figure. These data are drawn from stations A2017 and D2017 (see full datasets in "Shulman et al_BLtransitionDepth_A2017.csv" and "Shulman et al_BLtransitionDepth_D2017.csv").
Figure 3: "plot.Figure03.m" is a Matlab m file that contains all necessary data and code to re-create Figure 4.
Figure 4: "plot.Figure04.m" is a Matlab m file that contains all necessary data and code to re-create Figure 4.
The open access research publication featuring this data, "Comparisons of Underwater Light From Atmospheric and Mechanically Stimulated Bioluminescence Sources in High Arctic Polar Night," was published in the Journal of Geophysical Research: Oceans on 4/29/2024.
