A pair of event tables (in a list) documenting the movements of tagged Coho Salmon (Oncorhynchus kisutch) in Bear Creek (Southwest Alaska, USA) for 29 July - 19 August 2008. Table motion lists individual fish residence time intervals in each of three stream regions, while table origin lists the study-wide residence time of each fish and the stream region in which the fish was first tagged.
Two data frames motion and origin with 1,140 rows and 149 rows of 4 variables, respectively.
from, to - start and end times as seconds since 1970-01-01 UTC (POSIXct)
fish.id - unique identifier for each fish
region - stream region (1 = 0 - 930 m, a cold downstream region with abundant and spawning sockeye salmon; 2 = 930 - 1360 m, a cold middle region with few if any sockeye salmon; 3 = > 1360 m, a warm upstream region where sockeye salmon were absent)
