Putative spawning rises, meaning abrupt movements of fish to shallower depths, identified in archival tag data for 3 female 
Greenland halibut (Reinhardtius hippoglossoides) tagged in 2004, 2006, and 2012 (tag nos. 5282, 4551, and 383, respectively) in 
the eastern Bering Sea. (A) Tag-recorded depths of fish are provided for the first 50 d of the year (grey circles), with black cir- 
cles indicating depths during spawning rises. Panel titles are the tag number and the year data were recorded (e.g., 5282:2004 
means data recorded in 2004 for the fish implanted with tag no. 5282). (B) Close-ups of spawning rises that reached an esti- 
mated depth <400 m are provided, with the time for the minimum depth recorded set to 0 min to align all the rises. In each B 
panel, horizontal dashed lines at depths of 200 and 350 m are shown as references.
