March through August Ice Edge Positions in the Nordic Seas, 1750-2002, Version 1

This product contains ice edge coordinates for the Nordic Seas from 1750 through 2002 for months March through August. Ice edge in this product is defined as the outer boundary of ice having at least 30 percent ice concentration. Data are derived from publicly available sea ice products and use observational data from ship logbooks, diaries, and other sources in addition to more recent satellite data products from the Scanning Multichannel Microwave Radiometer (SMMR) and the Special Sensor Microwave Imager (SSM/I).

本数据集涵盖1750年至2002年北欧海域3月至8月的海冰边缘坐标。本数据集所界定的海冰边缘，指冰浓度不低于30%的海冰的外边界。该数据集的数据源自公开可用的海冰产品，同时纳入了船舶日志、航海日记及其他来源的观测数据，此外还使用了扫描多通道微波辐射计（Scanning Multichannel Microwave Radiometer, SMMR）与专用传感器微波成像仪（Special Sensor Microwave Imager, SSM/I）的最新卫星数据产品。
