quently below mean high water. Finally, Alaska argues that Dinkum Sands should be treated as an island when it is in fact above mean high water. We find no error in the Master's conclusion.

In the proceedings before the Master, the United States took the position that an island must be "permanently" above mean high water, Brief for United States on Dinkum Sands 17-29, while Alaska argued that Article 10 permits a feature "to slump on occasion below" mean high water but still qualify as an island, Brief for Alaska on Dinkum Sands 64. The Master essentially rejected the United States' position in favor of a somewhat more lenient standard, under which an island must "generally," "normally," or "usually" be above mean high water. Although Alaska now objects to this standard, Alaska Exceptions Brief 44-45, 51, it sets forth no clear alternative. Alaska's observation that "an island that is occasionally submerged is no less an island," id., at 45, is not inconsistent with the Master's approach.
If Alaska is now implicitly claiming that a feature need appear only episodically above mean high water to qualify as an island, its position is without merit. Because Article 10(1) does not specify how frequently a feature must be above mean high water to qualify as an island, we must look to the Convention's drafting history for guidance. See Louisiana Boundary Case, 394 U. S., at 42-47. In urging that the Master's interpretation of Article 10(1) is inconsistent with the development of that provision, Alaska focuses on the fact that earlier drafts specified that an island must be "permanently above high-water mark."
