Visualization of a single simulation replicate of instrumental-based surveys for seals and polar bears in the Chukchi Sea. First, a realization of abundance (N) is simulated for each species (a). Next, virtual transect surveys are conducted, yielding counts for each species (b). Note that grey cells are unsurveyed. Finally, abundance is estimated (; c), and compared to simulated abundance to tabulate performance metrics.
