Propose an undersea feature name

You can propose names for undersea features such as seamounts, troughs, ridges and sea channels on the continental shelf of New Zealand and in the Ross Sea region of Antarctica.

On this page

We encourage other nations to consult with us before naming undersea features within our jurisdiction.

We have the exclusive right to name undersea features within 12 nautical miles of our territory. Beyond that anyone can propose an undersea feature name, but they must consult with us first if the feature is within our responsibility.
