Experimental results: Remineralization experiments to assess the ability of natural assemblages of bacteria to utilize DOM produced under Si and N limitation (SBDOM project, SBC LTER project)

<p>Culture studies of diatoms that dominate spring blooms in the Santa Barbara Channel were used to examine the effects of N and Si stress on the magnitude of production and the chemical composition of DOM (see the <a href=\"http://www.bco-dmo.org/dataset/518427\">BIB Experiments</a> dataset). The ability of natural assemblages of bacteria to utilize DOM produced under Si and N limitation was then assessed using remineralization experiments. Species examined in the remineralization experiments include: <em>Skeletonema marinoi</em>, <em>Chaetoceros socialis</em>, <em>Thalassiosira weissflogii</em>, and <em>Odontella aurita</em>.</p>
