<div><p>Seawater samples for pigment analyses were immediately filtered (2 to 5 l volume) onto Whatman 47 mm GF/F filters under low vacuum (<0.5 atm). The filters were blotted dry, and stored in 2 ml cryotubes (Fisher) in liquid nitrogen until analysis. Analyses were performed within 6 months to a year of sampling.</p>
<p>Extraction procedures and HPLC analytical methods follow those described in Thomas (2012) and HPLC_Method_Summary.pdf (see related files and publications). </p></div>

HPLC analysis
<div><p>HPLC samples were analyzed during August-September 2018 at the Horn Point Analytical Laboratory by Meg Maddox (<a href="mailto:mmaddox@umces.edu">mmaddox@umces.edu</a>). Values of -8888 indicate concentrations that were below detection levels. Values of -9999 indicate missing data. Coefficient of variation (replicate filter precision) for all NSF_Gulf_Rapid_HPLC samples was TChl a = 3.09%; Ppig = 4.28%.</p>
<p>The HPLC was controlled by Agilent Chemstation software.</p></div>
