dataset
posted on 2025-01-29, 03:07 authored by TESS NELSONTESS NELSON, Grant HoseGrant Hose

Three stygofauna taxa were examined how they responded to groundwater drawdown under different sedimentary environments.

Treatments:

Stygofauna taxa - Amphipoda, Harpacticoid and Cyclopoida

Drawdown rates - Fast 400 cm/day, medium 100 cm/day, slow 40 cm/day, very slow 4 cm/day and control no flow.

Sedimentary environments - Coarse gravel, fine gravel, coarse sand, medium sand and fine sand.

Upon completion of drawdown experiments, the location of stygofauna with columns were counted by separating columns into segments (15-12 cm (top), 12-9 cm, 9-6 cm, 6-3 cm and 3-0 cm (bottom), and counting under a microscope.

FAIR Self Assessment Summary

This text has been generated from a tool that has been adapted from the ARDC FAIR Assessment Tool Findable -------- Does the dataset have any identifiers assigned? Global Is the dataset identifier included in all metadata records/files describing the data? Yes How is the data described with metadata? Comprehensively (see suggestion) using a recognised formal machine-readable metadata schema What type of repository or registry is the metadata record in? Data is in one place but discoverable through several registries Accessible ---------- How accessible is the data? Publicly accessible Is the data available online without requiring specialised protocols or tools once access has been approved? Standard web service API (e.g. OGC) Will the metadata record be available even if the data is no longer available? Yes Interoperable ------------- What (file) format(s) is the data available in? In a structured, open standard, machine-readable format What best describes the types of vocabularies/ontologies/tagging schemas used to define the data elements? Standardised vocabularies/ontologies/schema without global identifiers How is the metadata linked to other data and metadata (to enhance context and clearly indicate relationships)? The metadata record includes URI links to related metadata, data and definitions Reusable -------- Which of the following best describes the license/usage rights attached to the data? Standard machine-readable license (e.g. Creative Commons) How much provenance information has been captured to facilitate data reuse? Partially recorded
