   Climate change is predicted to shift or extend the range of warm-water species poleward. In 2014, the fiddler crab was observed for the first time at the PIE LTER site in Northeast Massachusetts, which is north of its historical range. Beginning in 2014, density estimates were collected.

   Density (individuals per m2) of epibenthic invertebrate (on the surface such as snails and amphipods) for Rowley River tidal creeks associated with long term fertilization experiments, Rowley and Ipswich, MA. 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. Marsh fertilization from 2004 - 2016 at Sweeney Creek and 2005, and 2009-2016 at Clubhead Creek. Nutrient enrichment ended in 2016.

4. Nekton individual data from flume net collections along Rowley River tidal creeks associated with long term fertilization experiments, Rowley, MA.

   Deegan, Linda; Nelson, J (January 2022, Environmental Data Initiative)

   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.

5. Marsh plant species stem counts for Rowley River tidal creeks associated with long term fertilization experiments, Rowley and Ipswich, MA.

   Marsh plant species stem counts for Rowley River tidal creeks associated with long term fertilization experiments, Rowley and Ipswich, MA. 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 2012 and at Clubhead Creek in 2005 and from 2009 till 2012. The reference creeks, West and Nelson, have been sampled in pair with the nutrient enriched creeks.
