Betula nana ring widths

Ring width data for Betula nana shrubs growing near the terminus of the Russell Glacier in western Greenland. Samples were collected in support of Cassandra Gamm's M.S. thesis at the University of Alaska Anchorage. The goal of the measurements was to examine long-term growth trends in relation to changes in climate. Data are available in both .rwl and column (.csv) format.本数据集为格陵兰西部罗素冰川（Russell Glacier）周边生长的矮桦（Betula nana）灌丛的年轮宽度数据。样本采集工作系为支撑卡桑德拉·甘姆（Cassandra Gamm）在阿拉斯加安克雷奇大学的硕士学位论文而开展。本次测量的核心目标为探究与气候变化相关的长期生长趋势。数据集提供.rwl与逗号分隔值（.csv）两种格式。
