Complex Region Spatial Smoother (CReSS)
(University of St Andrews, 2011) - ReportConventional smoothing over complicated coastal and island regions may result in errors across boundaries, due to the use of Euclidean distances to represent inter-point similarity. The new Complex Region Spatial Smoother ... -
Comparing pre- and post-construction distributions of long-tailed ducks Clangula hyemalis in and around the Nysted offshore wind farm, Denmark : a quasi-designed experiment accounting for imperfect detection, local surface features and autocorrelation
(University of St Andrews, 2011) - ReportWe report a novel technique to model abundance patterns of wintering seaducks in relation to the construction of an offshore wind farm (OWF) based on seven years of aerial survey transect data. Distance sampling was used ... -
Density estimation implications of increasing ambient noise on beaked whale click detection and classification
(University of St Andrews, 2010) - ReportAcoustic based density estimates are being increasingly used. Usually density estimation methods require one to evaluate the effective survey area of the acoustic sensors, or equivalently estimate the mean detection probability ... -
Comparison of aerial survey methods for estimating abundance of common scoters
(CREEM, University of St Andrews, 2009) - ReportDuring the month of March, four survey methods were applied to the SPA at Camarthen Bay. WWT staff carried out visual aerial surveys using distance sampling methodology (Camphuysen et al. 2004). Visual shore-based counts ... -
