160083/160000, the seascape comma, otherwise described as the undecimal hemifourths comma, is an 11-limit unnoticeable comma measuring about 9/10 of a cent. Tempering it out gives the highly accurate rank-4 seascape temperament, which splits the perfect fourth, 4/3, into two intervals of 231/200.
The name comes from the typical base-10 fractional representation of this interval bearing a striking resemblance of that of the landscape comma, 250047/250000, while only adding 11 to the mix of prime factors, and being of a relatively similar size.
