What is PiE 2018?

Particle in Europe, or PiE, is a bi-annual conference on the measurement, monitoring, impact, and managing of in situ particle size and concentration in the aquatic environment. The meeting is sponsored by Sequoia Scientific, Inc. of USA and the Instituto Hidrografico Marinha of Lisbon, Portugal. Specialists from many fields but with a common interest in particles in water attend in an intimate, informal environment and exchange ideas on phenomena, dynamics, and technologies.
