Meiofaunal counts, 2003-2009, from marsh cores along Rowley River tidal creeks associated with long term fertilization experiments, Rowley, MA. The long term fertilization experiment, TIDE project, aims to simulate eutrophication on a large scale by the addition of NO3- aiming to reach 70µM concentrations from May to September every year during the growing season. This fertilization of the marsh has been going on at Sweeney Creek since the 2004 growing season and at Clubhead Creek in 2005 and then again in 2009 .本数据集为2003年至2009年采自美国马萨诸塞州罗利市罗利河潮汐溪沿岸沼泽沉积物柱样的小型底栖生物（Meiofaunal）计数数据，该区域配套开展有长期施肥实验。本次长期施肥实验即TIDE项目，旨在通过添加硝酸根离子（NO₃⁻）模拟大规模富营养化过程，在每年生长季的5月至9月将水体硝酸根浓度维持在70微摩尔（µM）的目标水平。其中，斯威尼溪（Sweeney Creek）的沼泽施肥实验自2004年生长季起持续开展，克拉布黑德溪（Clubhead Creek）则分别于2005年、2009年实施施肥处理。
