| International Bathymetric Chart of the Arctic Ocean, Version 3.0 |
 |
IBCAO Version 3.0 represents the largest improvement since 1999 taking advantage of
new data sets collected by the circum-Arctic nations, opportunistic data collected
from fishing vessels, data acquired from US Navy submarines and from research ships
of various nations. Built using an improved gridding algorithm, this new grid is on
a 500 meter spacing, revealing much greater details of the Arctic seafloor than IBCAO
Version 1.0 (2.5 km) and Version 2.0 (2.0 km). The area covered by multibeam surveys
has increased from ~6 % in Version 2.0 to ~11% in Version 3.0. |
