With shoreside assistance from Marv Lilley, Jason carefully inserted this temperature and resistivity probe into a 340 ºC vent chimney at Diva vent in the International District vent field. Credit: UW/NSF-OOI/WHOI, Dive J2-1546, V23.

We saw an assemblage of scale worms, palm worms, and blue colonial ciliates surrounding the chimneys at the "Diva" vent in the International District vent field. Credit: UW/NSF-OOI/WHOI, Dive J2-1546, V23.

About one hour of dive J2-1545 was spent finding the perfect location for the RAS/PPS fluid sampler vent cap. It had to be warmer than 20 ºC (so that we know that it's vent fluid) but not TOO hot, so that it wouldn't block the pump input with sulfide deposits. The still camera is positioned to monitor the site for the next year. Credit: UW/NSF-OOI/WHOI, Dive J2-1545, V23.

Mystery! We encountered these green orbs on a few 2023 dives, mostly at 200 - 500 m depths, off the OR coast and at Axial Seamount. At first we thought they might be clogged larvacean houses, but they're all perfectly circular. Credit: A. Simmen, University of Washington.
