We’re delighted to announce – and invite you to attend – the INPAS Symposium – exploring the effects of Impulsive Noise on Porpoises and Seals.

INPAS will be a one day symposium presenting the latest research on marine mammals and impulsive noise. The symposium will take place in Amsterdam, The Netherlands, on 12th June 2018 and is intended to bring together scientists, regulators, industry, and environmental groups to present and discuss the big picture of impulsive noise on marine mammals. It’s made possible by Rijkwaterstraat, Gemini Windpark in the Netherlands and is being coordinated by Floor Heinis of HWE (Heinis Waterbeheer en Ecologie) and our own Cormac Booth. You can register here!

This symposium will capture some of the latest updates in research on marine mammals and impulsive noise – with a focus on species occurring in the North Sea – and presents an excellent opportunity to keep discussions advancing. We’ll be posting an update next week with the speakers, titles and abstracts. But we’ve got a summary for you below. We have structured the presentations around three broad thematic questions (but we recognise there is a lot of overlap across these topics):

What is disturbance and when does it occur?: The presentations in the first block will focus on effect distances for porpoises and seals: contributions by Jakob Tougaard (Aarhus), Christ de Jong (TNO); on noise propagation and possible disturbance areas, Gordon Hastie (University of St. Andrews/SMRU) and Geert Aarts (Wageningen Marine Research); on seal tagging and effects of OWF noise, Isla Graham (University of Aberdeen) and Miriam Brandt (BioConsult SH); and on effect distances of porpoises due to piling noise in the UK and Germany (GEISHA project), respectively.

What is the effect of disturbance on individuals?: Jonas Teilmann (Aarhus University) will talk about the foraging efficiency of porpoises at various circumstances, with contribution of Ron Kastelein (SEAMARCO) on porpoise energetics and noise. A summary of what we know about energetics in seals will be given by David Thompson (University of St Andrews/SMRU).

What is the significance of disturbance, i.e. what is the effect on populations?: In the third block we will focus on the extrapolation of effects on individuals to population effects. John Harwood (University of St. Andrews/SMRU) will start with a general introduction on PCoD (concepts, sensitivity of models), leading into Jacob Nabe-Nielsen presenting the individual based model approach of DEPONS, followed by Bernie McConnell (University of St. Andrews) presenting on the IBM seal project he is involved in. The program will be structured in such a way that there are lots of opportunities to contribute to discussions. At the end of the day we intend to determine the key gaps and decide on a roadmap for future research. The symposium will be chaired by René Dekeling (Dutch Ministry of Infrastructure and Water Mangement).

Whilst the symposium is an open invite event (so Register now!), Cormac will also be coordinating and facilitating a closed expert elicitation to update the transfer functions in the Interim PCoD model.
