Distribution of adult Sockeye and Chinook salmon migrating over the marine array. If a fish was detected at more than one receiver, a proportion was allocated to the receiver, for example, if an ID code was detected on two receivers, each receiver was assigned a value of 0.5. The values above the bars indicate the proportion of time that the receiver was operational during the season. ‘No data’ indicates the extent of the inshore region lacking instrumentation. Right hand labels (grey bars) indicate sub-array distances (km) from the center of the release area.
