It would only be redundant if the context had already made it unambiguous that it was water. It is possible to be submerged under any liquid: for example french fries are cooked submerged under hot oil (they can't be cooked submerged under hot water).
Yes, "submerged underwater" is redundant. Submerged under anything is redundant since the prefix "sub-" means "under." In most cases, the use of "submerged" alone is sufficient. In case there is some question about the substance something is submerged in (not necessarily liquid, not necessarily tangible), you might occasionally have use for "submerged in water."
It is used to express someone who says very little often is very knowledgeable and has profound thoughtIt is used to express someone who says very little often, but can be very knowledgeable and have profound thought."Still waters run deep."Some rivers have rough surfaces with waves. That's usually because the water is shallow and there are rocks near the surface. But deep rivers have no rocks near the surface and the water is smooth and still. "Still waters run deep" means that people who are calm and tranquil on the outside, often have a strong, "deep" personality.still (adjective) = calm, motionlessdeep (adjective) = going far down
Still Waters - Run Deep - was created in 1996.
'Unknown' is an adjective, 'waters' is a common noun. Possibly the expression is the title of something in particular that you meant, in which case you should have capitalised it.
The noun 'water' is a singular, uncountable noun, a word for a substance. Units of water are expressed in measures or forms such as cups of water, glasses of water, bodies of water, etc.The plural noun 'waters' is a word specifically for an area of seawater bordering on and under the control of a country (territorial waters); water from a particular source (the waters at Baden-Baden); or used for a particular type of situation (troubled waters).The word 'water' is also a verb: water, waters, watering, watered.

Surface waters of the Earth are typically referred to as "water bodies" or "water sources," which include oceans, seas, rivers, lakes, and streams. These surface waters play a crucial role in supporting various ecosystems and human activities.
Ponds and lakes typically undergo turnover in the fall and spring. In the fall, cooling surface waters sink and mix with deeper, oxygen-rich waters. In the spring, warming surface waters mix with cooler, nutrient-rich waters.

water lilies help them adapt in water. they usually float on the surface of quiet waters, with the stalk reaching down to the bottom of the pond. some varieties, however, grow completely under water, even producing their flowers and fruits while submerged.
Upwelling is the ocean process that brings vital nutrients from the bottom to the surface waters. It occurs when cold, nutrient-rich waters from the deep ocean rise to the surface, fueling the growth of phytoplankton and supporting a vibrant marine ecosystem.

Buoyancy is the force exerted by the weight of water displaced by an object that is at least partially submerged in the water. Surface tension a force of attraction exerted between water molecules at the waters surface interface. Something can not become submerged in the water until this surface tension is broken. Surface tension is a very weak force and can be overcome physically or by changing the chemistry at the surface (adding a wetting agent).
The pH of surface waters is often higher than that of most ground waters due to the presence of carbon dioxide, organic matter, and various minerals that can lower groundwater pH. Surface waters are influenced by atmospheric interactions and photosynthetic activity, which can increase pH by removing CO2 and promoting the formation of bicarbonates. Additionally, surface waters may receive inputs from alkaline sources, such as runoff from soils rich in limestone. In contrast, groundwater can be more acidic due to longer residence times and the leaching of minerals.
