If you take a gallon of water from the deepest ocean and bring it up to the surface in a sealed container, will the pressure break the container as it is risen up into the surface?

At the depth of the typical ocean floor — about 3km — water is compressed to 98.2% of its sea-level volume. The Mariana Trench is just over 11km deep, producing a pressure of around 1100 atmospheres, so water there is compressed to around 94% of its sea-level volume.
