Realtime data from International District Seafloor CTD

(MJ03D-CTDPFB307)

 

Update: This instrument stopped working on 14 Nov 2025, but then came back online on 15 Jan 2026, so realtime data is now being plotted again.

 

This page displays plots of realtime data (updated every 15 minutes) from the seafloor CTD instrument located at the International District at Axial Seamount, part of the National Science Foundation's (NSF) Ocean Observatories Initiative (OOI) Regional Cabled Array (RCA), operated by the University of Washington. The seafloor CTD at the International District was installed in summer 2024. 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).
