Macroinfaunal counts, 2003-2017, from marsh cores along Rowley River tidal creeks associated with long term fertilization experiments, Rowley, MA.

Macroinfaunal counts, 2003-2006, 2007, 2009, 2012-17, 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 from 2009 till 2016. Fertilization stopped in 2016.本数据集收录2003-2006年、2007年、2009年及2012-2017年的大型底栖无脊椎动物计数数据，采集自马萨诸塞州罗利市罗利河潮汐水道沿线的沼泽沉积物岩心，该区域配套开展了长期施肥实验。本长期施肥实验即TIDE项目，旨在通过添加硝酸根离子（NO₃⁻），在每年生长季的5月至9月将水体浓度提升至70微摩尔（μM），以此大规模模拟富营养化过程。该沼泽施肥实验于2004年生长季起在斯威尼水道（Sweeney Creek）启动，2005年开始对俱乐部头水道（Clubhead Creek）实施施肥，并于2009年至2016年持续推进相关实验，最终于2016年停止施肥。
