This side really okay we're finally preparations are done
yeah here we go
swishes lock
hi this bill Chadwick from Oregon State University I'm out on the Falkor one of
the things we saw at daikaku sea map that was really amazing was this tiny
little sulfur chimney bubbles of gas are coming out and it's spinning out sulfur
at the same time this was something that none of us had ever seen before and it
was so amazing to see hi my name is Julie Huber I am a marine microbiologist
sailing aboard the hydrothermal hunt cruise and these two berms are
fascinating because the way they make a living in this really harsh ecosystem is
through a symbiotic relationship with bacteria so single-celled organisms that
live in the gut of these two worms they're fixing carbon and using the
hydrogen sulfide that's in the venting fluid to create organic carbon that the
worms use to grow
we baptized it that's right it was an exciting dive I'm super proud of
Sebastian right so if this has been a long time coming it's been about a year
and a half that I started on this project and now to see it actually bring
up some samples and scientists with smiles on their face and the vehicles
back on board so we'll be going in tomorrow and just exploring a little bit
more today we were able to pick up snails from tomorrow Simone Alvina conca
and I'm pretty sure the species here is the diamond species at a mantis only
known once before one place the hairy snails among the most heat tolerant
animals that we have in the ocean so they live on smokers right around the
highest flows that we found of about 50 to 60 degrees if you peel the back the
shell you would see a very large Gill and the skill has symbiotic there
chemosynthetic bacteria they need access to the vent flows the hydrogen sulfide
so these snails sit in piles around the vent in the high flow pumping water over
their gills to feed their symbiotic and that's how they are then fed from the
same violence these animals want to get to hot water but don't want to burn so
they got to hit it just right they have to find the right sweet spot
we're hoping to see some patterns here you know we're looking for is there a
characteristic set of vent chemistry biological communities that exist in the
backyard we're trying to fill a gap in knowledge
right now and that's really what this particular cruise is about
