Patent ID: 8051727

Claim:
A pore-water sampler for collecting pore-water samples at desired depths above and below a sediment-water interface, the pore-water sampler comprising: a plurality of sample intake probes, each sample intake probe receiving a separate pore-water sample and each sample intake probe comprising: an inner probe fitting having an opening on an outer wall thereof to receive the pore-water sample, a tip attached to a bottom of the inner probe fitting, the tip being placed in or on bottom sediment of an aquatic system, and a first filter positioned at the bottom of the inner probe fitting above the tip and adjacent to the opening in the outer wall of the inner probe fitting, the first filter providing a first filtering of the respective pore-water sample; a plurality of second filters respectively connected in-line to the tops of the sample intake probes, the second filters each having a pore size less than a pore size of the first filters and providing a second filtering of the respective pore-water samples; a plurality of sample containers respectively connected in-line to the second filters to receive, without atmospheric exposure, the pore-water samples filtered by the respective second filters; and a sample triggering system connected to the sample containers to initiate sampling.
