Enter the room while building a shinespark and use it on the lowest part of the ramp to diagonally spark up and out of the water. Use very low jump height space jumps to carry momentum to the far side of the submerged ramp. Both Choots must be killed. Using Screw Attack: stay a little bit high in the water so that it remains active for the second Choot. Using Plasma or ammo: kill the first Choot while running down the middle platform, and the second while gliding above it after spacejumping through the water. Then shinespark up and use SpaceJump to reach the door.
