A bizarre sponge, Chondrocladia lampadiglobus, seen at Axial Base (2600m deep). First seen in 1960 in grainy black and white pictures, it was originally thought to be a Russian listening device by the US Navy, before it was eventually identified as an organism.

The HPIES instrument is being lowered over the side of the R/V Thompson for installation at the base of Axial Seamount. The HPIES (Horizontal Electrometer Pressure Inverted Echosounder) measures the horizontal electrical field, the bottom pressure, and the acoustic travel time from the seafloor to the sea surface to characterize the properties of the water column.
