Description:

A numerical model of ocean ﬂow, hydrography, and transport is used to extrapolate observations of currents and hydrography and infer patterns of material ﬂux in the deep ocean around AxialSeamount, a destination node of NSF’s Ocean Observatories Initiative’s Cabled Array. Using an inverse method, the model is made to approximate measured deep ocean ﬂow around this site during a 35 day time period in the year 2002. The model is then used to extract month-long mean patterns and examinesmaller-scale spatial and temporal variability around Axial. Like prior observations, model month-long mean currents ﬂow anticyclonically around the seamount’s summit in toroidal form with maximum speeds at 1500 m depth of 10–11 cm/s. As a time mean, the temperature (salinity) anomaly distribution takes theform of a cold (briny) dome above the summit. Passive tracer material continually released at the location of the ASHES vent ﬁeld exits the caldera primarily through its southern open end before ﬁlling the caldera.
