资源简介:

<p>This dataset includes Doliolid abundance, carbon and nitrogen content, depth, temperature, salinity and in situ chlorophyll a from 25 cruises on the RV/Savannah at the South Atlantic Bight, Mid-Continental Shelf, (31 N 80 W) during 2015-2017. From the bottle samples, the following parameters were also measured:<br /> - Average chemical extracted size fractionated total and &gt; 8 um chlorophyll&nbsp;a and phaeophytin (mg m-3)<br /> - Total and size fractionated (&lt;10 um) POC (mg m-3 and mole L-1)<br /> - Total and size fractionated (&lt;10 um) PON (mg m-3 and mole L-1)<br /> - Total and size fractionated (&lt;10 um) delta13C (per mil vs PDB standard)<br /> - Total and size fractionated (&lt;10 um) delta15N (per mil vs air N2)<br /> - Average delta13C (per mil vs PDB standard) and delta15N (per mil vs air N2) of starved D. gegenbauri zooids.<br /> - D. gegenbauri abundance (individuals m-3)</p>

本数据集涵盖了2015年至2017年间,在南大西洋湾(South Atlantic Bight)大陆架中部(北纬31°、西经80°)海域,由萨凡纳号研究船(RV/Savannah)执行的25个航次所采集的纽鳃樽(Doliolid)丰度、碳氮含量、水深、水温、盐度及原位叶绿素a数据。通过采水器采集的样品,还测定了以下参数: - 经化学萃取分级得到的总叶绿素a、>8 μm级分叶绿素a及脱镁叶绿素的平均含量(单位:mg·m⁻³) - 总颗粒有机碳(Particulate Organic Carbon, POC)及<10 μm级分颗粒有机碳(单位:mg·m⁻³ 与 mol·L⁻¹) - 总颗粒有机氮(Particulate Organic Nitrogen, PON)及<10 μm级分颗粒有机氮(单位:mg·m⁻³ 与 mol·L⁻¹) - 总及<10 μm级分的碳稳定同位素比值δ¹³C值(相对于PDB标准,单位为‰) - 总及<10 μm级分的氮稳定同位素比值δ¹⁵N值(相对于大气氮,单位为‰) - 饥饿状态下的格氏纽鳃樽(D. gegenbauri)个虫的平均δ¹³C值(相对于PDB标准,单位为‰)与平均δ¹⁵N值(相对于大气氮,单位为‰) - 格氏纽鳃樽丰度(单位:ind·m⁻³)
