In a measurement taken on Wednesday, NASA’s Curiosity rover discovered startlingly high amounts of methane in the Martian air, a gas that on Earth is usually produced by living things. The data arrived back on Earth on Thursday, and by Friday, scientists working on the mission were excitedly discussing the news, which has not yet been announced by NASA.
The measurement this week found 21 parts per billion of methane, or three times the 2013 spike.
Even before this week’s discovery, the mystery of methane has been deepening.
Curiosity scientists developed a technique that enabled the rover to detect even tinier amounts of methane with its existing tools. The gas seems to rise and fall with the red planet’s seasons. A new analysis of old Mars Express readings confirmed Curiosity’s 2013 findings. One day after Curiosity reported a spike of methane, the orbiter, passing over Curiosity’s location, also measured a spike.

It is like there is some sort of seasonal bloom we have not been able to see yet.
At least that is what it seems like to me.
