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."
Water Lily and Lotus are some I know

While submerged in water? ie. Swimming outside Yes because while you are swimming you are still receiving some of the sun's rays, they should change.
A water lily is fully submerged an sends its leaves and flowers up to the surface.
The unit weight of submerged soil: Submerged Density (kN/m3) = Saturated Density - Water Density Water Density = 9.81 kN/m3
No, it is a floating plant, i know you might argue that the roots are underwater while the leaves are above but actually that counts as a floating plant, or else water hyacinth and water lettuce are half-submerged too. Floating plants is a plant that has it's leaves above water and it's roots dangling in water, partially submerged is leaves above water but roots in the soil below water, completely submerged is the roots in the soil below and the leaves also below water surface. -LJTG
None! It was 1918-20 that saw the creation of new countries and the revival of submerged countries ...
The floating leaves of hydrophytes usually float on water while those of submerged leaves are usually submerged in water as the name suggests.
When an object is immersed in water, it means it is completely surrounded or covered by the water.
Yes
No, Cabomba is a partially-submerged plant. It is rooted in soil at the bottom of the pond with its leaves, flowers, fruits on or above the surface of the water.
