None of this is good news. The ocean in the area has become warmer and it is affecting marine life negatively.
How much damage there is and what the long term consequences are in unknown. The area will need to be watched.
Is this a sign of bigger more serious changes in the oceans? It is possible. Any ocean change is not a good sign. Changes in the patterns of marine life behavior 
can mean serious changes are taking place. We should be worried.
