MIXS:0000013 env_local_scale 0..1 Report the entity or entities which are in the sample or specimen’s local vicinity and which you believe have significant causal influences on your sample or specimen. We recommend using EnvO terms which are of smaller spatial grain than your entry for env_broad_scale.

MIXS:0000014 env_medium 0..1 Report the environmental material(s) immediately surrounding the sample or specimen at the time of sampling. We recommend using subclasses of 'environmental material' ( EnvO documentation about how to use the field: .

MIXS:0000183 salinity 0..1 The total concentration of all dissolved salts in a liquid or solid sample. While salinity can be measured by a complete chemical analysis, this method is difficult and time consuming. More often, it is instead derived from the conductivity measurement. This is known as practical salinity. These derivations compare the specific conductance of the sample to a salinity standard such as seawater. None .
MIXS:0000110 samp_store_temp 0..1 Temperature at which sample was stored, e.g. -80 degree Celsius None .
