[¦man·ə·mō′lim·nē‚än]
(hydrology)
The dense bottom stratum of a meromictic lake; it is stagnant and does not mix with the water above.

These latter authors report a [H.sub.2]S value of 70 [micro]mol/L and the monimolimnion extends from 13 m down.
It is still a meromictic lake, with high [H.sub.2]S concentration in the monimolimnion. The lake is not much warmer than previous reports, although surface temperatures were always higher than reported historical minimum.
Water samples for contaminant analyses from depths of 2 m (underneath the ice cover), 10 m (the bottom of the mixed layer), and 32 m (in the monimolimnion) were taken with a 6.2 L Kemmerer sampler (all-plastic construction) and transferred to two new 4 L polypropylene bottles rinsed three times with lake water.
The total PFC concentrations at depths of 2 and 10 m (both located within the mixed layer) did not differ significantly from one another, but both were significantly higher than the total PFC concentrations at 32 m, in the monimolimnion, which were close to our MDLs (two-way ANOVA: F = 27.49, p = 0.04).
It is a deep (maximum 489m), meromictic lake, with oxic mixolimnion up to 70m and a deep monimolimnion rich in dissolved gases, particularly methane [9].
On the other hand, the word MONIMOLIMNION is the longest possible word that can be formed from the letters of 20 different windows, attributable to the fact that the word's letters are spread across a relatively small part of the alphabet, I-O.
We may thus justify reference henceforth to the upper mixolimnion and lower monimolimnion of Laguna de Guatavita.
The meromictic stratification and the substantially hypoxic condition of the monimolimnion surely benefit ammonification, leading to relatively high values of ammonia and phosphates in deep water.
