You might be wondering how our Hydrothermal Hunt is going – and perhaps more importantly - you might be wondering how you are doing in our betting pool. (You have made a guess as to where
We have used a combination of CTD tow-yos and Sentry AUV dives to conduct our search for hydrothermal vents
Due to an ominous weather forecast, we then decided to temporarily skip Segments 8 & 9 so that we could survey Segment 10 before the weather turned worse. There we measured our largest plume signals yet when our CTD hovered briefly apparently nearly right over a vent on the seafloor. The Segment 10 “investors” on board were suddenly euphoric, like their favorite sports team had just won the game by coming from behind at the last minute, while the Segment 5 fans (me) were crushed and demoralized, let down again after a short-lived dream of glory! But Segment 10 fans better not get too cocky – after all, we have two more segments yet to survey (Segments 8 & 9) and they could be de-throned just as unceremoniously as I was.
Overall, our Hydrothermal Hunt has been very successful so far. We have explored 8 of the 10 back-arc segments, and we’ve found that 6 of those segments are hydrothermally active. And we’ve got 2 more segments to explore, so there could be more. What surprises might those segments have for us? Keep following to find out!
