a Sediment Community Oxygen Consumption (SCOC) dataset

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]
