"mean water temperature" is a correct and commonly used phrase in written English.
It refers to the average temperature of a body of water over a certain period of time. Example: The researchers collected data on the mean water temperature of the lake over the past year, showing a gradual increase in temperature due to climate change.
On the basis of their observations of iceberg deterioration, American researchers W.F. Weeks and Malcolm Mellor have proposed a rough formula for predicting melt loss: –Z = K D, where Z = loss in metres per day from the walls and bottom of the iceberg, K = a constant of order 0.12, and D = mean water temperature in °C averaged over the draft of the iceberg.
We employed presence absence data and five variables: altitude, distance from the river source, surface of catchment area, annual mean water temperature, and annual mean water flow.
Clearfell harvesting raised the yearly mean water temperature by between 0.25 °C and 0.94 °C, and raised the maximum water temperature by between 0.84 and 1.6 °C.
The mean water temperature (WT), which is an important factor to control aquatic life, varies between 25 and 31 °C from different sites.
Tidal and seasonal fluctuation of mean water temperature at the selected measuring points ranged from 19.23°C to 31.57°C with an average of 27.15°C.
To test this, we performed a three-month outdoor mesocosm experiment exposing a natural soft-bottom community of benthic plants and animals to four different treatments: relatively low mean water temperature (18 °C) with low (< 4%) and high (c. 31%) trematode prevalence in the snail population, and relatively high mean water temperature (22 °C) with low and high trematode prevalence.
Mean water temperatures achieved for each of the three nominal temperatures tested (23, 26 and 29 °C) were 21.4 ± 0.3, 26.5 ± 0.2 and 29.7 ± 0.4 °C, respectively, with the salinities obtained consistent with nominal salinities (30, 35 and 40‰).
To examine whether the Mg/Ca-based temperatures of marine sediments represent SSTs, core-top temperatures reconstructed using Mg/Ca were compared with observed summer to autumn (June November) mean water temperatures at depths of 0 50 m from the JODC database (Fig. 4c f).
Although the highest monthly mean water temperatures outside embayments on the temperate Pacific Coast are typically much lower than this, regional climatic variation produces monthly mean water temperatures in excess of 21°C in some parts of both San Francisco and Anaheim Bays.
The cohorts encountered mean water temperatures that ranged over 8.8°C, encompassing nearly all of the seasonal variability in this region.
Mean water temperatures increased by only 0.3°C (to 30.5°C) in the month prior to the disease outbreak in 2008, whereas temperatures increased by 1.7°C in the month prior to the 2009 outbreak and reached 31.7°C.
