IBCAO v. 5 (International Bathymetric Chart of the Arctic Ocean version 5)

Knowledge about seafloor depth, or bathymetry, is crucial for various marine activities, including scientific research, offshore industry, navigation, and ocean exploration. Mapping the central Arctic Ocean is challenging due to the presence of perennial sea ice, which limits data collection to icebreakers, submarines, and drifting ice stations. The International Bathymetric Chart of the Arctic Ocean (IBCAO) was initiated in 1997 with the goal of updating the Arctic Ocean bathymetric portrayal. The project team has since released four versions, each improving resolution and accuracy. Here, we present IBCAO Version 5.0, which offers a resolution four times as high as Version 4.0, with 100 × 100 m grid cells compared to 200 × 200 m. Over 25 % of the Arctic Ocean is now mapped with individual depth soundings, based on a criteria for what is considered mapped that depends on water depth. Version 5.0 also represents significant advancements in data compilation and computing techniques. Despite these improvements, challenges such as sea-ice cover and political dynamics still hinder comprehensive mapping.

Statement

Data is collected by Stockholm University, analysed and cleaned by data processors, and combined into a grid with smoothing and interpolation methods to fill in blank regions without data.

Description

IBCAO Version 5 contains data from numerous sources and mapping methods, totalling roughly 1400 datasets. A majority of these are multibeam and single-beam datasets from research cruises, though they also include measurements from isolated soundings, lidar, optics, gravity data, interpolations, bathymetric charts, pre-generated grids, and steering points.
