Now Available: Version 1.0

The full spectrum
of soil life.

GloSED is the first dataset to map the entire soil eukaryome—from fungi and protists to plants and animals—across 4,000+ standardised sites worldwide.

Revealing the
Dark Taxa

Standard metabarcoding misses what it doesn't know. GloSED uses long-read sequencing (PacBio) and an expert-curated dark taxa framework to illuminate lineages that short reads discard.

  • Full-length ITS and 18S-V9 coverage
  • Expert-curated dark taxa

A truly global baseline.

From the Amazon to the Arctic, we sampled 351 terrestrial ecoregions using identical protocols.
