NODC Standard Format Seabed Oxygen Consumption from In-Situ Sources (F050) Data (1974-1978) (NODC Accession 0014186)

This data type contains data from analyses of seabed oxygen consumption determined from measurements over a specified time interval of initial and final dissolved oxygen concentration. Cruise information, position, date, time, number of replicates (repeat measurements), bottom depth, temperature, dissolved oxygen concentration and oxygen saturation are reported for each experiment. General environmental information may include meteorological and sea surface conditions, water transparency, elapsed time, initial dissolved oxygen concentration, final dissolved oxygen concentration, oxygen consumption and weight percent organic matter are reported for each replicate. Data on water column respiration (e.g., oxygen concentration, oxygen consumed or produced) may also be reported.

本数据集收录经分析得到的海底耗氧量数据，该数据通过对规定时间区间内的初始与终态溶解氧浓度（dissolved oxygen concentration）进行测量计算得到。每项实验均记录航次信息、采样位置、日期、时间、重复测量次数（replicates，即repeat measurements）、海底水深、水温、溶解氧浓度以及氧饱和度（oxygen saturation）。通用环境信息可涵盖气象与海面状况、水体透明度、历时时长；每项重复实验均记录初始溶解氧浓度、终态溶解氧浓度、耗氧量以及有机质质量百分比（weight percent organic matter）。此外，本数据集还可收录水柱呼吸作用（water column respiration）相关数据（例如氧浓度、耗氧量或产氧量）。
