CTD bottle data matched to dissolved, inorganic nutrient concentrations and to stable isotope measurements of particulate nitrogen and carbon rom R/V Melville cruise MV1110 in the Western Tropical North Atlantic in 2011

<p>Hydrographic data&nbsp;and water samples collected during casts with a CTD-rosette system (SBE911plus equipped with a fluorometer, transmissometer, oxygen sensor, and a PAR sensor)</p>

<p>Nutrient samples were run at sea using a Lachat QuickChem 8000 flow-injection analyzer equipped with the following methods:</p>

<p>Phosphate&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 31-115-01-1-I<br />
Silicate&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 31-114-27-1-B<br />
Nitrate+Nitrite&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 31-107-04-1-A<br />
Nitrite&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 31-107-05-1-A</p>

<p>Particle (particulate N and C) samples for stable isotope (d15N, d13C) were collected and analyzed following methods in Montoya et al. 2002.&nbsp;</p>
