1999年，国际北冰洋等深线图发布了第一份网格等深线汇编。自那时以来，国际北极科学组织的测深描绘支持了广泛的北极科学活动，例如，为海洋环流模型提供了约束条件，并为界定和提出关于北极海底地貌地质起源的假设提供了手段。IBCAO 3.0版是自1999年以来最大的改进，利用了环北极国家收集的新数据集，从渔船收集的机会数据，从美国海军潜艇和各国研究船获得的数据。这个新网格使用改进的网格算法构建，间距为500米，比IBCAO 1.0版（2.5公里）和2.0版（2.0公里）显示了更多的北极海底细节。多波束调查覆盖的区域从2.0版的6%增加到3.0版的11%。引文：Jakobsson，M.，等人（2012年），《北冰洋国际等深线图（IBCAO）3.0版》，地球物理学。保留信函：39，L12609，doi：10.1029/2012GL052219。
The International Bathymetric Chart of the Arctic Ocean (IBCAO) released its first gridded bathymetric compilation in 1999. The IBCAO bathymetric portrayals have since supported a wide range of Arctic science activities, for example, by providing constraint for ocean circulation models and the means to define and formulate hypotheses about the geologic origin of Arctic undersea features. 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 similar to 6% in Version 2.0 to similar to 11% in Version 3.0. Citation: Jakobsson, M., et al.
