GenBank accession numbers for ammonia oxidizer genes collected on the R/V Endeavor (SQO-Delta) in the San Francisco Bay Delta during September and October 2007.

<p>Surface sediment samples were collected for potential nitrification rates, using sediment slurries with filtered site water. Ammonia oxidizer gene abundances (AOA and AOB <em>amoA</em>) were quantified using qPCR, and clone libraries for each gene were sequenced using Sanger sequencing.</p> <p><strong>Related Manuscript: Damashel <em>et al., </em>2015</strong></p> <p>&nbsp;</p>
