Interactive Effects of UV Radiation and Vertical Mixing on Phytoplankton and Bacterial Productivity of Ross Sea Phaeocystis Blooms

Abstract: Data from five research cruises from OPP grant entitled "Interactive Effects of UV and Vertical Mixing on Phytoplankton and Bacterial Productivity of Ross Sea Phaeocystis Bloom (OPP0127022). The first two cruises were ships of opportunity cruises in the Pacific Ocean, the first collecting data between Valapariso, Chile and San Diego, CA (October 2002). The second and third cruises combined to provide data in a transect from 70 N to 68 S latitude in the Pacific ocean (August - November 2003). The remaining two cruises were to the Ross Sea, the first in December 2004 - January 2005 and the last from October - November 2005. Data presented include microbial biomass (bacterial direct counts) and chlorophyll a concentrations, bacterial production (as leucine or thymidine incorporation), solar irradiance data, CTD profiles, and one set of under water diffuse attenuation coefficients of for the Ross Sea.

摘要：本数据集源自OPP资助项目《紫外辐射与垂直混合对罗斯海棕囊藻（Phaeocystis）水华期间浮游植物与细菌生产力的交互影响》（项目编号OPP0127022）的5个研究航次所获观测数据。前两个航次为太平洋海域的机会航次：第一个航次于2002年10月在智利瓦尔帕莱索至美国加利福尼亚州圣迭戈海域开展数据采集；第二个与第三个航次合并完成了太平洋海域北纬70°至南纬68°的断面观测，观测时段为2003年8月至11月。剩余两个航次的作业海域为罗斯海：第一个航次于2004年12月至2005年1月开展，最后一个航次则于2005年10月至11月实施。本数据集包含的观测数据包括：微生物生物量（细菌直接计数结果）、叶绿素a浓度、以亮氨酸或胸苷掺入量表征的细菌生产力、太阳辐照度数据、CTD（温盐深剖面仪）剖面数据，以及一套罗斯海海域的水下漫射衰减系数数据集。
