The density of ringed seals (Phoca hispida) in 2 to 4 km 2 study plots was determined using a combination of removal sampling to determine density of seal holes and estimates of hole to seal ratios. A dog survey technique was adapted to removal sampling, where seal holes located under the snow by th...
