Sidescan data from the FRAM strait (PS126 expedition, 2021) collected by the Ocean Floor Observation and Bathymetry System (OFOBS).

This data upload comprises all the Ocean Floor Observation and Bathymetry (OFOBS) binned sidescan data collected from ca. 2 m above seafloor during the PS126 RV Polarstern Arctic expedition to the FRAM strait. The data gives a spatial assessment of the seafloor structure of numerous seafloor locations across the FRAM strait, in high resolution, as mapped by the EdgeTech sidescan system mounted on the OFOBS. For a description of the OFOBS and sidescan system specifically, please see the IEEE open-access paper (Purser et al., 2018, DOI: 10.1109/JOE.2018.2794095).

Naming format for files is :

1) First four digits, year of collection.
2) next two digits, month of collection.
3) next two digits, day of the month of collection.
4) final six digits, hour, minute and second of collection.

As an example "20210619210227_binned.jsf" was recorded at 21:02:27 on the 19th June, 2021.
