Black holes under the sea

Hello again, 

Another weird thing ive come across. Two black holes under the ocean. Now im not sure if its a glitch on the app or something but still weird. 

Heres the co-ords

56°22'57"N 143°34'18"E

Of course these are not real holes. Such places can be sometimes found in GE. The reason is probably that shallow areas were not covered with real imagery (the seabed is not a real image but a simulation). Here is an example at 76 ° 57'09.90 "N 157 ° 21'52.41" E.

At one point, the real picture was "forgotten".
