Less than 200 Million years old.
The ocean is 4 billion yars old, however due to subduction, the oldest sediment found in the ocean's floor is 180 million years old.
It is believed that old rocks are rare on ocean floors bevause the floor has manny remains and we are not unable to reach them

don't hold back
The oldest oceanic crust is in the west Pacific and north-west Atlantic. They are about 180 to 200 million years old.
The oldest recorded iceberg was estimated to be over 18,000 years old. It broke off from the Ross Ice Shelf in Antarctica and drifted in the Southern Ocean.
The oldest rock on the ocean floor can be found in the central parts of the ocean basins, particularly in regions known as abyssal plains. These rocks are generally around 200 million years old or older.
The oldest in-situ oceanic lithosphere is found at lithospheric subduction zones, where oceanic crust is being drawn into the mantle. These would normally be the point furthest away from its point of origin at the mid-ocean ridge.However the oldest remnant of oceanic crust found on earth dates from the early Archean when the lithosphere began to develop and are a product of obduction (where slivers of oceanic crust are thrust onto a continental crustal plate rather than below them). An example would be the Jamestown Ophiolite Complex of the Barberton greenstone belt in South Africa which formed approximately 3.5 billion years ago.
The oldest sediments recovered by deep-ocean drilling are around 180 million years old. These sediments are typically found in the Pacific Ocean and provide valuable information about Earth's history and past environmental conditions.
The oldest ocean, geologically, is the Panthalassa Ocean which was around 220 million years ago in the Triassic era. It encompassed the whole Earth except the land mass Pangea. See related link for more information.
the oldest are old bcause they are old
