Start date: 6 August 2014 - End date: 8 August 2014
Time: 9:00 am - 5:00 pm

The Centre for Research into Ecological and Environmental Modelling (CREEM) will be running a 2.5 day workshop to introduce participants  to modelling spatially explicit change in environmental impact assessment in  our purpose-built facilities at the University of St Andrews, Scotland. The course will comprise both taught and  practical sessions, with time for discussion on the morning of the third day.

In line with results based on a large scale study  undertaken by CREEM (commissioned by Marine Scotland) we introduce the  recommended modelling approach for baseline characterisation and EIA analyses.  Specifically, we outline the CReSS spatially adaptive smoothing method using  SALSA for model selection (Mackenzie et  al., 2013, Scott-Hayward et al.,  2013a, Walker et al., 2011). This workshop will introduce these methods to  the participants and describe how they can be used for EIA analysis using the  MRSea package in R.

The content of the course is below:


  • Basic features of baseline characterisation and  EIA data
  • Survey methods
  • Correcting for imperfect detection: Distance  sampling analyses
  • Modelling spatially explicit change:
    • Exploratory  data analysis
    • Model  fitting using CReSS and SALSA
    • Diagnostic  tools
    • Prediction  and inference and the identification of compelling spatially explicit change

We will illustrate the taught and practical material based  on simulated data based on existing (large off-shore) marine renewables  developments. This data is found within  the R package we will use throughout – the MRSea package.

The workshop will begin at 09:00 on Wednesday 6th  August, with registration at CREEM from 08:45 and will finish at lunchtime on Friday 8th.
