Distance sampling is a survey technique widely used to estimate the density and abundance of marine mammal populations, and other taxa. The Centre for Research into Ecological and Environmental Modelling are pleased to announce that we will be running 2 live online workshops this May on aspects of distance sampling. Registration is now open. The workshops are: - Practical design and simulation to optimise distance sampling surveys, 9-12 May 2022. Good survey design is critical to get the most out of marine mammal distance sampling surveys, which typically involve high field costs. Simulation is an inexpensive way to investigate design alternatives and optimize at the planning stage. We will demonstrate available free tools for this. - Distance sampling when animals are missed at zero distance, 17-18 May 2022. In marine mammal surveys animals may be missed because they are below the water and so unavailable to visual observers, or because of difficult sighting conditions. (Analogous issues occur for other types of marine mammal survey, such as passive acoustic surveys.) We will teach methods for dealing with these situations, and practical software tools. For more details, and to register, go to https://workshops.distancesampling.org We are offering one free place on each workshop with the goal of to widening participation to scientists from countries with fewer resources and groups traditionally under-represented in wildlife science. More details are at http://workshops.distancesampling.org/widening-participation and the closing date for applications for the widening participation scholarships is April 18th.
