Production vs Irradiance data from RVIB Nathaniel B. Palmer cruise NBP0103 in the Southern Ocean in 2001 (SOGLOBEC project)

<h2>Production vs Irradiance</h2>

<p>&nbsp;</p>

<p><strong>A short note on the \"Southern Ocean Grid System\":</strong> The grid is a Cartesian plane covering the sample region in which distances are easy to calculate. The grid system used for SOGLOBEC is a universal transverse mercator (UTM) projection with a certain base point and rotation. The base point was chosen in the far south and the rotation was chosen to create one axis along the peninsula, and the other offshore. The units of UTM are meters, but the points are chosen in km rounded to the nearest km. Negative numbers mean that samples were taken southwest of the y axis or southeast of the x axis. For more details see: <a href=\"http://globec.whoi.edu/so-dir/soglobec.grid.txt\"> Complete explanation of the Southern Ocean grid system. </a></p>
