This video is a compilation of bathymetry data of the submarine Havre Volcano system on the Kermadec Ridge, 400km North of New Zealand. 🌋🌏 @utas_earth_sciences @havrevolcano . Bathymetry is the study of mapping the ocean floor. This video shows 3 bathymetric layers: 1) ship based bathymetry of the whole volcanic system (the main caldera crater is 5 km wide!), 2) high resolution AUV bathymetry from the autonomous underwater vehicle Sentry @woodshole_ocean taking over 20 days of mapping, and 3) elevation differences between 2002 and 2015 bathymetry showing us the locations of new lava and mass wasting deposits! . More detailed results of the eruption that formed all of this new lava can be found in an Open Access paper published last month in Science Advances 🔎🔬: "The Largest Deep Ocean Silicic Volcanic Eruption of the Past Century"! ~~~~~~~~~~~ . #science #nature #geology #earthcapture #earthscience #geoadventure #discover #explore #ocean #oceanography #geophysics #volcanology #blue #sea #deepsea #stem #technology #auv #seafloor #tech #robot #robotics #stemeducation #scicomm #education #outreach #sciencecommunication #valentines #ilovescience

Sentry is an Autonomous Underwater Vehicle used to map the seafloor in extremely high resolution (less than 1 meter!!). This could be used to find indivudal rock features, bacterial colonies, black smokers and even fine details of a shipwreck! . Being autonomous, it is not remotely operated, instead it has a set plan programmed into it's system which it then follows. This can be updated by signaling to Sentry as it constantly feeds back it's data stream. . It can also be used to attach other geophysical surveying instruments and to measure water chemistry. She really is a nifty little robot; extremely helpful for when we were mapping volcanoes out at sea in the SW Pacific! . . #science #nature #geology #earthcapture #earthscience #geoadventure #discover #explore #ocean #oceanography #geophysics #volcanology #blue #sea #deepsea #stem #technology #auv #seafloor #tech #robot #robotics #stemeducation #scicomm #education #outreach #sciencecommunication #lifeatsea #pacific

30 tags and 1 profile in descriptionSampling volcanoes on the seafloor is no easy feat, but with a little help from our (to be) Supreme Robotic Overlords, it's possible! 🌋🤖 . An ROV (Remotely Operated Vehicle) is controlled from a surface ship and control room and can be sent underwater to explore the seafloor. The benefit of this over manned submarines is the ability to pack lots of technology into the same space: cameras, sampling methods, instruments and software. . Here, the ROV is going to retrieve a temperature probe that it placed into volcanic sediment. The objective was to measure heat flow near hydrothermal vents in a recently active volcanic system (Havre, 2012). This @woodshole_ocean ROV is called Jason 🙌 . It's rare to get pictures of ROVs in action on the seafloor without a #RobotSelfie , but we mounted a #gopro onto another platform that we sent to the seafloor to place our samples on. . For being taken at 1km deep, it really is an astounding photo! . #science #nature #geology #earthcapture #earthscience #geoadventure #discover #explore #travel #ocean #oceanography #geophysics #volcanology #blue #sea #deepsea #ROV #robot #robotics #photography #naturephotography #underwater #underwaterphotography #technology #stem #scicomm #outreach #sciencecommunication

It was a huge privilege to represent NIWA and join an international team of scientists for several weeks on a research expedition to the Kermadec Trench! I was lucky enough to see 6 new marine mammal species (including the biggest mammal in the ocean!), 100’s of incredible sea birds and also learn all about life 10km below the surface!
