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

How we got this date

NSF lists this award's end date as 31 January 2031.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 31 May 2031.

Abstract

Some of the ocean’s most efficient swimmers, including jellyfish, salps, and siphonophores, move by expelling water in the form of vortex rings. These vortex rings are created by the systematic contraction and relaxation of their bodies. Colonial siphonophores have many small, flexible, jetting units along their body. These units can coordinate to produce multiple pulsed vortex rings at once, enabling efficient…
