Nekton species counts and density from flume net collections along Rowley River tidal creeks associated with long term fertilization experiments, Rowley, MA.

The flume nets were deployed with the purpose of capturing salt marsh nekton. Nekton species were identified to the lowest taxonomic level using species keys. The 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 through 2016 and at Clubhead Creek in 2005 and from 2009 till 2016. Years 2017-2020 are enrichment recovery years.

本研究布设流槽网（flume nets）以采集盐沼自游生物（nekton）。自游生物物种通过物种检索表（species keys）鉴定至最低分类阶元。TIDE项目（TIDE project）旨在通过添加硝酸根离子（NO3-），于每年生长季的5月至9月间将浓度提升至70μM，以模拟大规模富营养化过程。该盐沼养分添加干预自2004年生长季起在斯威尼溪（Sweeney Creek）持续实施至2016年，在克拉布黑德溪（Clubhead Creek）则于2005年及2009年至2016年间开展。2017年至2020年为富集恢复阶段。
