Summary of activities from 2018-20

Since February 2018, IBCSO is part of the Nippon Foundation – GEBCO Seabed 2030 Project.  In the scope of this project, work on IBCSO v2.0 was intensified. Different to IBCSO v1, IBCSO v2.0 covers the area south of 50°S, thus more than doubling the area of seafloor covered.  Over the course of the past two years, data handling and workflows have been developed and optimised to cope with increase data volumes.  Furthermore, additional bathymetric datasets have been integrated continuously in the IBCSO database.  In February to April 2019 large areas in the Powell Basin were mapped during expedition PS118 with RV Polarstern.  These data will be included in IBCSO v2.0.  Throughout the past 2 years IBCSO was presented at international conferences, meetings and workshops.

The publication of IBCSO v2.0 is anticipated for late 2020/early 2021.
