Putative spawning rises, meaning abrupt movements of fish to shallower depths, identified in archival tag data for 6 male 
Greenland halibut (Reinhardtius hippoglossoides) tagged in 2004 (tag nos. 4122, 4126, 5319, 5364, and 5385) and 2005 (tag no. 
5385) in the eastern Bering Sea and in 2010 (tag no. 3883) in the Aleutian Islands. (A) Tag-recorded depths of fish are provided 
for the first 50 d of the year (grey circles), with black circles indicating depths during spawning rises. Panel titles are the tag 
number and the year data were recorded (e.g., 4122:2004 means data recorded in 2004 for the fish implanted with tag no. 4122). 
(B) Close-ups of spawning rises that reached a 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.
