Nassarius obsoletus (Ilyanassa obsoleta) length and biomass measurements for Rowley River tidal creeks associated with long term fertilization experiments, Rowley and Ipswich, MA.

Abstract: 

Nassarius obsoletus (Ilyanassa obsoleta) 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 2014 and at Clubhead Creek in 2005 and from 2009 till 2014.

All samples taken in late 2009-10, 2012-2014 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. Sweeney has been fertilized every summer from 2004-2014 Clubhead had been fertilized in 2005 and then from 2009-2014.

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