Table 3
Example values of metabolic rates in some selected lakes. Z mean (m): mean depth of the lake, GPP (mmol O2 m−2 d−1): gross primary production, ER (mmol O2 m−2 d−1): ecosystem respiration, NEP (mmol O2 m−2 d−1). International country codes based on the ISO 3166 standard published by the International Organization for Standardization (https://www.iso.org/iso-3166-country-codes.html) are in parentheses.
