TN249-10, TN250-10 Chlorophyll and Primary Production 2010. Version 1.0

These data were collected from process stations and other stations where the Phytoplankton Ecology Lab of BIOS collected bulk chlorophyll (Chl) measurements on the following Bering Sea Ecosystem Study-Bering Sea Integrated Ecosystem Research Program (BEST-BSIERP) cruises: TN249 and TN250. Data presented are total and >5um Chla, and total and >5um primary production. All samples were collected on the eastern Bering Sea shelf from 55-63oN and 164-180oW during spring and summer. At process stations, seven (7) depths were sampled representing roughly the 100%, 55%, 30%, 17%, 9%, 5% and 1.5% light depths. At other stations, generally four (4) depths were sampled and were chosen as surface, deep chlorophyll maximum, and two other depths selected based upon equal distributions throughout the water column or profile features (e.g., elevated concentrations near the bottom). The data were collected from 11 May 2010 through 12 July 2010. BEST-BSIERP together are the Bering Sea project.

这些数据采集自过程站位及其他站位，BIOS浮游植物生态学实验室在以下白令海生态系统研究-白令海综合生态系统研究计划（Bering Sea Ecosystem Study-Bering Sea Integrated Ecosystem Research Program, BEST-BSIERP）航次中开展了批量叶绿素（Chl）测量：TN249和TN250。所呈现的数据包括总叶绿素a（Chla）、大于5微米的叶绿素a、总初级生产力及大于5微米的初级生产力。所有样本均于春季和夏季在白令海东部陆架（北纬55°至63°、西经164°至180°）采集。在过程站位，采集了7个深度的样本，大致对应100%、55%、30%、17%、9%、5%和1.5%的光照深度；在其他站位，通常采集4个深度的样本，选择依据为表层、叶绿素最大深度，以及另外两个根据水柱均匀分布或剖面特征（如近海底浓度升高）选取的深度。数据采集时间为2010年5月11日至7月12日。BEST-BSIERP共同构成白令海项目。
