Abstract:Macroinfaunal counts, 2003-2006, 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 through 2011 and at Clubhead Creek in 2005 and then from 2009 till 2011.

Taxonomic Protocols
Organisms studied Manayunkia aestuarina, Fabricia sabella, Nereis diversicolor, Streblospio benedicti
 
Methods:Macroinfauna samples were taken with push corers (6.6 cm inner diameter) in the sediment to a depth of 5 cm. Animals retained on a 500 micron sieve were enumerated and identified. Samples taken along an inudndation gradient at low tide from the mudflats to the high marsh along three transects within each creek branch.

Creeks-
Reference creeks are West and Nelson
Nutrient Enriched creeks are Sweeney and Clubhead. Sweeney was fertilized every summer (May-Sept, ~120 days) from 2004-2006. Clubhead had been fertilized in 2005 . A branch of each creek was selected for fish reduction where the killifish Funudulus heteroclitus was reduced ~60-80%. Killifish reduction occurred from 2004-2006.

All creeks have two branches determined by direction at confluence while facing upstream (Left or Right).
