Chlorophyll a and Phaeo Pigments from Bottle Casts and Ice / Ice Cores A short note on the "Southern Ocean Grid System": 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> METHODS: Chlorophylls were dissolved in 90% acetone and measured using a Turner Designs Digital 10-AU-05 Fluorometer. The instrument was calibrated using chlorophyll a standards from Sigma Chemicals as noted below. Calibration Notes: NBP0103 Calibrated at start of cruise using Sigma Chemicals chl_a standard. Calibration values used were as follows:     High Fd: 0.109 High tau: 1.970 Med Fd: 0.111 Med tau: 1.950 Low Fd: 0.109 Low tau: 2.215     Calibration Notes: NBP0104 Calibrated at start of cruise using Sigma Chemicals chl_a standard. Calibration values used were as follows:     High Fd: 0.090 High tau: 1.982 Med Fd: 0.092 Med tau: 1.981 Low Fd: 0.100 Low tau: 2.215     Calibration Notes: NBP0202 Calibrated at start of cruise using Sigma Chemicals chl_a standard. Calibration values used were as follows:     High Fd: 0.109 High tau: 1.954 Med Fd: 0.103 Med tau: 1.949 Low Fd: 0.100 Low tau: 1.954     Calibration Notes: NBP0204 Calibrated at start of cruise using Sigma Chemicals chl_a standard. Calibration values used were as follows:     High Fd: 0.149 High tau: 1.887 Med Fd: 0.141 Med tau: 1.968 Low Fd: 0.149 Low tau: 1.938     Data submitted by: Maria Vernet Scripps Institute of Oceanography University of California, San Diego La Jolla, California 92093-0218 Phone: 1-858-534-5322 email: <a href="mailto=mvernet@ucsd.edu">mvernet@ucsd.edu</a> Last update: November 30, 2005; gfh

叶绿素a及类黄素色素来自瓶体沉淀物及冰/冰芯关于“南大洋网格系统”的简要说明：该网格为一个笛卡尔平面，覆盖采样区域，其中距离易于计算。SOGLOBEC所采用的网格系统为一种带特定基准点和旋转的通用横轴墨卡托（UTM）投影。基准点被选在远南端，旋转被选以在半岛上创建一条轴线，另一条则向海中延伸。UTM的单位为米，但选取的点以千米为单位，四舍五入至最接近的千米。负数表示样本取自y轴西南侧或x轴东南侧。更多详情请参阅：<a href="http://globec.whoi.edu/so-dir/soglobec.grid.txt">南大洋网格系统的完整说明。</a>方法： 叶绿素溶解于90%的乙醚中，并使用Turner Designs Digital 10-AU-05荧光计进行测量。仪器使用Sigma Chemicals提供的叶绿素a标准品进行校准，具体如下。校准说明：NBP0103 在航次开始时使用Sigma Chemicals的chl_a标准品进行校准。 使用的校准值如下：  高Fd：0.109 高tau：1.970 中Fd：0.111 中tau：1.950 低Fd：0.109 低tau：2.215  校准说明：NBP0104 在航次开始时使用Sigma Chemicals的chl_a标准品进行校准。 使用的校准值如下：  高Fd：0.090 高tau：1.982 中Fd：0.092 中tau：1.981 低Fd：0.100 低tau：2.215  校准说明：NBP0202 在航次开始时使用Sigma Chemicals的chl_a标准品进行校准。 使用的校准值如下：  高Fd：0.109 高tau：1.954 中Fd：0.103 中tau：1.949 低Fd：0.100 低tau：1.954  校准说明：NBP0204 在航次开始时使用Sigma Chemicals的chl_a标准品进行校准。 使用的校准值如下：  高Fd：0.149 高tau：1.887 中Fd：0.141 中tau：1.968 低Fd：0.149 低tau：1.938  数据提交者：Maria Vernet 斯克里普斯海洋研究所 加州大学圣地亚哥分校 加利福尼亚州拉霍亚 92093-0218 电话：1-858-534-5322 电子邮件：<a href="mailto=mvernet@ucsd.edu">mvernet@ucsd.edu</a>最后更新：2005年11月30日；gfh
