What little we still know about our own planet! However, we are to believe the Global Warming Hoax and Climate Change Religion!
This is still a very incomplete map of the ocean floor around Antarctica! It still remains terra incognita to some extent in the year 2022!
"... Details a new deepest point — a depression called the Factorian Deep located at 7,432 meters (24,383 feet) below sea level. ...
500 meters grid squares, 23% [only 23%???] of these cells now have at least one depth measurement. ...
And there’s still a long way to go, the researchers argue. What we know from the planet’s underwater terrain largely comes from low-resolution satellite measurements that have infrared the presence of tall seamounts and deep valleys from the gravitational influence these have on the sea surface. So this is really just the start. ..."

"... Here we present IBCSO Version 2 (IBCSO v2) (Fig. 1) covering the area south of 50°S. The resolution is 500 m × 500 m in IBCSO Polar Stereographic projection (EPSG: 9354, see also the usage notes). It covers over 77 million km² of seafloor (approximately 2.4 times the area of seafloor covered by IBCSO v1). ..."
From the abstract:
"The Southern Ocean surrounding Antarctica is a region that is key to a range of climatic and oceanographic processes with worldwide effects, and is characterised by high biological productivity and biodiversity. Since 2013, the International Bathymetric Chart of the Southern Ocean (IBCSO) has represented the most comprehensive compilation of bathymetry for the Southern Ocean south of 60°S. Recently, the IBCSO Project has combined its efforts with the Nippon Foundation – GEBCO Seabed 2030 Project supporting the goal of mapping the world’s oceans by 2030. New datasets initiated a second version of IBCSO (IBCSO v2). This version extends to 50°S (covering approximately 2.4 times the area of seafloor of the previous version) including the gateways of the Antarctic Circumpolar Current and the Antarctic circumpolar frontal systems. Due to increased (multibeam) data coverage, IBCSO v2 significantly improves the overall representation of the Southern Ocean seafloor and resolves many submarine landforms in more detail. This makes IBCSO v2 the most authoritative seafloor map of the area south of 50°S."
