Sequoia Scientific

PiE Conference 2014

PiE Logo What is PiE 2014?

Particle in Europe, or PiE, is a bi-annual conference on the measurement, monitoring, and managing of in situ particle size and sediment concentration in the aquatic environment. The meeting is organized by Sequoia and a local organizer somewhere in Europe. PiE 2014 will be in Esbjerg, Denmark and it co-sponsored by University of Copenhagen and the MacArtney Underwater Technology Group.

Who should attend?

PiE brings together some of the world’s experts in measuring and monitoring particles in the water.  The presentations are not limited to specific technology or field of study.  Anybody interested in measuring, monitoring, modeling or managing particles in oceans, rivers, lakes, storm water, streams and ice: Researchers, students, environmental officials, government employees, and monitoring agencies should attend the meeting.



The meeting dates are Tuesday-Thursday 7-9 October 2014, with an icebreaker Monday evening 6th October 2014.


PiE 2014 will be in Esbjerg, Denmark.  With a population of ~75,000 Esbjerg is Denmark’s 5th largest city. Situated on the SW coast of Denmark, in the northern part of the European Wadden Sea area and with easy access to the North Sea the city is a magnet for beach lovers, bird watchers, tourists, and the offshore industry. Some of the largest offshore wind turbines in the world are being shipped out from Esbjerg, and offshore oil rigs frequently appear in the port for overhaul and service. With 2 universities there’s a vibrant student community and atmosphere. Esbjerg can be reached by car, bus, train, ferry or plane. Esbjerg airport, with daily connections to Aberdeen and Stavanger is less than 15 km from the city centre. Denmark’s 2nd largest airport, Billund, is 50 km away. Billund Airport has multiple daily connections to e.g. Frankfurt, Amsterdam, Paris, London and Copenhagen. You can also fly in to Copenhagen and take the train from Copenhagen to Esbjerg, a 3-hour trip. If you are arriving from the U.K. you might consider taking the ferry from Harwich to Esbjerg. Esbjerg itself is one of Denmark’s youngest cities, created from scratch after the Danish defeat to Germany in the 1864 war. Amongst other losses, this resulted in Denmark losing its main access port to the North Sea, Ankona to Germany. Denmark thus desperately needed a new port for access to the North Sea for export purposes, and Esbjerg was chosen.

What do past attendees have to say?

“The PiE meeting is one of the most scientifically informative as well as enjoyable conferences on my calendar.  I try not to miss it.”, – Rick Reynolds, Scripps Institution of Oceanography

“The PIE workshops provide an ideal opportunity to meet and discuss the latest research on aquatic particles.  Unlike conferences, its size allows for ample discussion in an environment that promotes inter-disciplinary cooperation. I have found these workshops to be thought provoking and a lot of fun.” – Tim Milligan, Bedford Institute of Oceanography

“The PIE workshops provide a forum for marine scientists from a number of disciplines to come together to assess our capability to measure and understand bodies in the water column, be they biological, flocculating cohesive sediments or non-cohesive sands. I have always enjoyed the workshops, finding them to be stimulating and interesting, with a good balance of the academic, social and informal.” – Peter Thorne, National Oceanography Centre, Liverpool, UK

“PiE is the kind conference that one should attend when dealing with particles in aquatic environments. The relative small number of participants, the specialised topics and the sufficient time for socializing with colleagues from other institutions makes the conference for me an event not to miss.” – Michael Fettweis, MUMM, Belgium

Who are the Keynote speakers?

Professor Daniel Hanes from St. Louis University, USA will talk about ‘The confounding effects of particle characteristics on acoustic backscatter measuring techniques’ and Professor Colin Jago from Bangor University, UK will talk about ‘SPM dynamics in a Region of Freshwater Influence (Liverpool Bay)’. Together, these talks are guaranteed to resonate with everybody that are curious about the prospects of using acoustics to quantify particle size and/ or concentration as well as studying particle dynamics in physically, biologically and optically complex waters.

Who else will be speaking?

The abstracts for talks have been received and have been organized into a preliminary program.  Click here to view the PiE 2014 Program (Last updated Oct 2nd).  Click here to view the Full Program with Abstracts (6.9Mb).  This program will be updated as changes are made to the program.  Check this page to the latest Program.

How do I get to Esbjerg Conference Hotel?

By Taxi from Billund Airport:

You can always take a taxi to Esbjerg. The cost is around DKK 500 one way and will take approximately 40 minutes. Taxis are parked just outside the arrival terminal. The destination address is Esbjerg Conference Hotel, Stormgade 200, 6700 Esbjerg.

By Bus from Billund Airport:

Bus # 144 departs Billund airport, just outside the arrival terminal and to within 150 m from Esbjerg Conference Hotel. The bus stop where you need to get off is called ‘Stormgade v Spangsbjerg Kirkevej’ (Stormgade / Spangsbjerg Kirkevej intersection’). It is by a Shell gas station. It is then a 150 m walk to Esbjerg Conference Hotel. Bus 144 departs every hour and the trip takes 1:50 hours. The cost is around 80 DKK one way. If you are staying in another hotel in Esbjerg, bus 144 terminates at Esbjerg Bus Station. It is then no more than a 5 minute walk to the city centre where most of the hotels are.

On you can check the departure times. Enter ‘Billund Airport (fly)’ in the From field and ‘Stormgade 200, 6700 Esbjerg, Esbjerg Kommune’ in the To field. Then select one of the options with Bus # 144. You have to purchase the bus tickets in the airport or on the bus as you board it. You cannot buy them on-line.

By Train from Copenhagen:

If you are arriving by train to Esbjerg you will end up at Esbjerg Central. This is just next to the bus station, so again, if you’re staying in a hotel in the city centre it is a 5 minute walk.

From Esbjerg Central you can take a taxi to Esbjerg Conference Hotel, a 5 minute drive.

You can also take the bus. Bus # 2 will take you to within 300 m of ECH. If you use, input ‘Esbjerg st’ in the from field and ‘Stormgade 200, 6700 Esbjerg, Esbjerg Kommune’ in the To field. The cost is 20 DKK one way and the trip takes 10-15 minutes.

You can also walk from Esbjerg Central to Esbjerg Conference Hotel– here’s a link to Google maps directions for the walk from the train station to Esbjerg Conference Hotel.

The Maritime and Fisheries Museum – the venue for the PiE conference dinner:

The Maritime and Fisheries Museum (, 3 km from the conference facilities is the venue for the PiE conference dinner. Sit down for a delicious dinner with a view of the North Sea. Take a stroll through the museum and check out the fish and seals at night, and discover the story of the Danish West coast.

The Wadden Sea National Park:

The Wadden Sea National Park, Denmark’s largest national park with an area of almost 1500 km2 ( begins just outside Esbjerg city limits. Birds are everywhere in the national park, as is Denmark’s largest herd of seals. As for particles, the Wadden Sea has plenty of those, ranging in size from tiny clay particles to big seals. Widespread muddy and sandy tidal flats abound. Large plankton blooms on the tidal flats makes it an ideal location for studying the interaction between biology, physics and geology – all kinds of particles! We’ll talk a lot more about this during the excursion to the park on Wednesday 8 October.

History of PiE:

The first PiE was held in Bologna, Italy in October 2008, organized by Sequoia and ISMAR and had some 40 participants.
