Magnetic anomaly processed data (PDF wiggle plots), Emperor Seamounts and Hess Rise, R/V Falkor cruise FK190726 (2019)
These processed marine magnetic anomaly wiggle plots were derived from the magnetic anomaly grids. The magnetic surveys were conducted at the Hess Rise and Emperor Seamounts in the North Central Pacific Ocean during R/V Falkor cruise FK190726 (chief scientist Les Watling). The cruise was primarily a biogeographic study using ROV SuBastian and the surveys were designed for ROV dive site selection and multibeam gap filling when time allowed. The data set is divided into 10 sites that represent places where the magnetometer was deployed for a dedicated survey with nearly parallel lines or some other pattern. The Emperor Seamounts surveyed include Suiko (3 surveys), Yomei, Nintoku, Jingu, Annei, and Koko (from north to south, respectively). Two surveys were carried out on Hess Rise. The 11th and final file of the data set (file name containing 20190822) is a short test file acquired during the return transit and is not one of the project study sites. The image data files are in PDF format and were generated as part of a project called Deep Coral Diversity at Emperor Seamount Chain 2019. Funding was provided by a grant from Schmidt Ocean Institute (Ship, ROV, gravimeter, magnetometer) to Les Watling, PI, and from NOAA OER grant number NA16OAR0110192 (Science support) to John R. Smith, PI.
