Seamount Mapping
July 16, 2017
Access Dive Summary and ROV Data

Today's remotely operated vehicle dive was cancelled due to high sea state, wind conditions, and shifting currents around Johnston Atoll. Instead, the team spent the day conducting mapping operations to add multibeam coverage to seamounts mapped by NOAA Ship Okeanos Explorer in 2015. New data were collected over ridge features extending northeast from Keli Ridge, resulting in a nearly complete map of the feature. Data were also acquired over top of a seamount to the east and resulted in a complete map of this unnamed seamount – providing new data and insights on the many seamounts and ridges in the Johnston Atoll Unit of the Pacific Remote Islands Marine National Monument.
