One thing I’ve learned from the Okeanos Explorer’s ROV trip to the Marianas Trench, is that deep sea jellyfish just like to let it all hang out. How else you going to feed effectively if you don’t wave your tentacles around like you just don’t care? But get too close to this unidentified jelly, and you risk triggering its Inspector Gadget quality evasive maneuvers. RETRACT! SWIM AWAY! Live to extend another day. You go jelly, you go.

Kim is a Senior Oceanographer at Sea-Bird Scientific. She received her Ph.D. in Physical Oceanography from the University of Washington in 2010. Her goal in life is to throw expensive s**t in the ocean. When not at sea, she has used observations from moored, satellite and land-based instruments to understand the pathways that wind and tidal energy take from large (internal tides) to small scales (turbulence). Her current mission is to make your oceanographic data be the best data it can be.
