Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

NSF lists this award's end date as 30 June 2031.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 October 2031.

Abstract

Underwater communication is much harder than over-the-air communication. Radio waves do not travel well in water. Underwater systems usually rely on acoustic communication, which uses sound to carry information. However, sound travels much more slowly and can transmit far less information than radio waves, making it difficult for underwater robots, sensors, and vehicles to communicate effectively and reliably. This…
