Abundance of 0+ snapper by water velocity.

<p>Snapper abundance is the maximum count observed within a one minute video sample. The left column of plots is for flood tide camera deployments, the right column for ebb tide camera deployments. Each row of plots represents snapper abundance as observed from a different camera position. Data presented have been subsampled to reduce temporal autocorrelation. The red line for each panel represents a 2^nd order polynomial quantile regression spline fitted through the 50^th percentile of the data.
