VerdexMicroplastic counts from Long Island’s south shore.
Verdex is a student-run sampling effort. We record microplastic particle counts in Long Island’s coastal waters under a published, version-locked protocol.
Every session, logged.
Sessions appear here whether the counts are interesting or not. Blank results and zero counts stay in the record — removing them would make the dataset a highlight reel.
One protocol, version-locked.
The Verdex Sampling Standard (VSS) v1.1 is adapted from NOAA marine-debris monitoring guidance. It was locked before Session 1 so that sessions stay comparable to one another.
Collect
Surface grab samples in pre-rinsed glass jars, rinsed three times in source water before filling. Nitrile gloves throughout. Site, time, tide stage, and weather recorded on the field sheet at the moment of collection.
Blank
A procedural blank is opened and handled alongside the real samples at every session from Session 1 forward. If the blank is dirty, the session's counts are reported with that blank value attached — never quietly dropped.
Filter
Samples are vacuum-filtered onto a 100 µm mesh in a covered workspace with foil-lined trays, then dried before examination.
Count
Particles are counted and typed as fiber, fragment, or bead under an Accu-Scope EXS-210-13 stereo microscope, with a hot-needle check on ambiguous particles. Counts and photos are entered into the Verdex sheet the same day.
Single-team disclosure
All samples to date were collected, processed, and counted by one team using one protocol. No independent laboratory has re-counted a Verdex sample, and inter-observer agreement has not yet been quantified. Counts are visual identifications, not polymer confirmations.
Verdex will not recruit additional teams or sites until it has completed six consecutive protocol-compliant sessions and closed at least one external methodology review.
