Abstract: 

Nassarius obsoletus (Ilyanassa obsoletus) length and biomass measurements 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 2016 and at Clubhead Creek in 2005 and from 2009 till 2016.

Methods

All samples taken in late 2009-10, 2012-2016 In the field, 10 quadrats were haphazardly tossed in the creek bottoms at low tide along 250 meters.

Creeks-
Reference creeks are West and Nelson
Nutrient Enriched creeks are Sweeney and Clubhead.

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