Realtime data from ASHES Seafloor CTD (MJ03B-CTDPFB304)
This page displays plots of near-real-time data (updated every 15 minutes) from the seafloor CTD instrument in the ASHES Vent Field at Axial Seamount, part of the National Science Foundation's (NSF) Ocean Observatories Initiative (OOI) Cabled Array seafloor observatory, operated by the University of Washington. The seafloor CTD at ASHES was installed in August 2017. The instrument samples at 1 Hz, but the data are downsampled to every 1 minute in the plots below. The dates/times in the plots below are in GMT (+8 hrs of local PST, or +7 hrs of PDT time on the US west coast).
