Sediment chemical and physical properties (DP1.20194.001)

This data product contains the quality-controlled, native sampling resolution data from NEON's aquatic sediment collection and field metadata, as well as associated chemical data (nutrients, carbon, heavy metals) and physical properties (sediment size and texture) provided by a contracted lab. Organic contaminants were analyzed prior to 2020. In 2022, sediment began to be archived for future analysis. Sediment field samples are collected in wadeable streams, rivers, and lakes 2 times per year (spring and fall). Samples are collected from several depositional zones, homogenized, subsampled, and shipped to an external lab. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage.

Latency:
The expected time from data and/or sample collection in the field to data publication is as follows, for each of the data tables (in days) in the downloaded data package. See the Data Product User Guide for more information.
