MBARI Mapping AUV near-bottom processed sub-bottom profile images (PNG format) at the Mid-Atlantic Ridge Puy des Folles Seamount, EMARK Massif, Falkor EMARK Vents, and Hydra (Grappe Deux) (2023)
This processed sub-bottom data set was collected with an Edgetech 2205 sonar/sub-bottom system flown at 50-m altitude on MBARI Mapping AUV mission surveys at four Mid-Atlantic Ridge sites: the summit of Puy des Folles Seamount from missions 20230310m1, 20230310m2, and 20230402m1; the EMARK Massif from missions 20230314m1, 20230314m2, 20230315m1, 20230316m1, 20230317m1, 20230317m2, 20230318m1, 20230319m1, 20230319m2; the Falkor EMARK Vents from missions 20230321m1, 20230321m2, and 20230323m1; and Hydra (Grappe Deux) from missions 20230325m1, 20230326m1, 20230328m1, and 20230329m1 (investigators David Caress, Jeffrey Beeson, Jennifer Paduan, Sharon Walker, David Butterfield). The data profile images are in PNG format and contain processed 1-6 kHz CHIRP sub-bottom data. The AUV survey missions were conducted during the 2023 R/V Falkor (too) cruise FKt230303 (chief scientist David Butterfield) to the Mid-Atlantic Ridge. Funding was provided by the Schmidt Ocean Institute and a grant from the David and Lucile Packard Foundation to MBARI.
