Methods and protocols used in the collection of this data package

Description:	Water samples are collected by a Van-Dorn sampler, and then transferred directly to 250ml Nalgene HDPE bottles and stored in cold room until analysis (max of 30 days). Water samples are analyzed by a Particle size distribution (PSD) measurement using Liquilaz LS200 (Particle Measurement Systems Inc., Boulder, Colorado, USA).
Instrument(s):	Liquilaz LS200
