Mark recapture distance sampling training workshop
Registration is now open for our latest online interactive training
workshop, on mark-recapture distance sampling. Join us by video from
anywhere around the world! For full details, and to register, please go to

Workshop Overview
Conventional distance sampling methods assume that all animals at zero
distance are detected with certainty. However, in some situations this
assumption is violated, and some animals are missed, causing a negative
bias in the density and abundance estimates. This occurs on some
shipboard surveys of marine mammals, for example, where animals may be
missed on the trackline because they are underwater while the survey
vessel passes, or because the sea conditions are rough so that even some
animals right on the line are missed. The former (being underwater and
so not available for detection) is often called availability bias and
the latter perception bias.
In this two-day workshop, we cover survey protocols and analytical
methods for dealing with both perception bias and availability bias.
The workshop is intended for those already familiar with the basics of
distance sampling.
