SCOC: a Sediment Community Oxygen Consumption (SCOC) dataset

Description Usage Format Author(s) References See Also Examples

Description

This literature dataset, compiled by Andersson et al. (2004) contains 584 measurements of sediment community oxygen consumption rates, as a function of water depth, and performed in deep-water sediments, either by in situ incubations or via modelling of oxygen microprofiles.

Usage

1

Format

a dataframe with 584 rows, and with following columns:

Depth.m, the water depth at which the measurement was performed.

SCOC.mmol/m2/d, the oxygen consumption rate of the sediment, [mmolO2/m2/d]
