A new bathymetric map of Lake Baikal

In 1999 it was decided to create an international team of specialists and combine efforts and expertise to produce a new, more accurate bathymetric map of Lake Baikal. The aim was to re-compile the original sounding data that were used for the 1992 maps, to digitise them, to correct them using up-to-date, calibrated acoustic velocity information, to integrate them with as much as possible of the more recently acquired sounding data, and to produce a new, computer-generated, computer version of the Lake Baikal bathymetry map based on ALL available sounding data.1999年，相关机构决定组建一支国际专家团队，整合各方力量与专业专长，以绘制一幅更为精准的贝加尔湖（Lake Baikal）湖底水深测绘图。本次工作的核心目标为：重新整编1992年版水深图所使用的原始测深数据，对其进行数字化处理；采用最新校准后的声速信息对数据开展校正；整合尽可能多的新近获取的测深数据；并基于全部可用测深数据，生成全新的计算机生成贝加尔湖湖底水深测绘图。
