Primary production in two lakes of contrasting morphometry in the Canadian Arctic was estimated independently from the differences in oxygen, pH, and carbon 14 uptake between light and dark bottles. The estimates were in general agreement. Together with production estimates from two other high latitude lakes reported in the literature the data show that the morphometry of the lake basins exerts a considerable control over rate of production, with the shallower lakes having a higher intensity of production (g C/m 3 /day) than the deeper lakes. The available data also suggest strongly that the rate of production is generally low in the Arctic, and that the amount of production accomplished by the more productive lakes is roughly the same order of magnitude as that of the least productive temperate lakes reported in the literature.
