资源简介:

SupplementaryTable1.xlsx lists all the samples used to calculate the regional reservoir correction. SupplementaryTable2.xlsx lists all information on the individual radiocarbon dates of all the cores used in the study: LabID, Depth [cm], 14C age ± error, Calibrated age (95% confidence range and mean), and Dated species. Please note that the age-depth relationships have been modeled using a Bayesian approach so the Calibrated ages might differ from the ages that would be yielded by the calibration of individual radiocarbon ages. SupplementaryTable3.xlsx contains all the data used in the study: OCE2017-GR02:- Depth [cm] - Age [ka BP] (this study)- N. pachyderma [%] (Telesiński et al. 2022)- summer sSST 100m [°C] (this study) MSM5-5-723:- Depth [cm]- Age [ka BP] (this study)- N. pachyderma [%] (Werner et al. 2015)- summer sSST 100m [°C] (this study)- PBIP25 (Werner et al. 2015)- Planktic foraminifera fragmentation [%] (Werner et al. 2003) JM10-330GC:- Depth [cm]- Age [ka BP] (this study)- N. pachyderma [%] (Consolaro et al. 2018)- summer sSST 100m [°C] (this study)- Planktic foraminifera [ind./g] (Consolaro et al. 2018) MSM5-5-712:- Depth [cm]- Age [ka BP] (this study)- N. pachyderma [%] (Werner et al. 2013)- summer sSST 100m [°C] (this study)- IRD flux [#/cm**2/kyr] (Werner et al. 2013, recalculated to the new age model)- PBIP25 (Müller et al. 2012) M23258:- Depth [cm]- Age [ka BP] (this study)- N. pachyderma [%] (Sarnthein et al. 2003)- summer sSST 100m [°C] (this study)- annual SST [°C] (Martrat et al. 2003) M17730-4- Depth [cm]- Age [ka BP] (this study)- N. pachyderma [%] (Telesiński et al. 2015)- summer sSST 100m [°C] (this study)- Planktic foraminifera [ind./g] (Telesiński et al. 2015) MD95-2011- Depth [cm]- Age [ka BP] (this study)- N. pachyderma [%] (Risebrobakken et al. 2003)- summer sSST 100m [°C] (this study)- Planktic foraminifera [ind./g] (Risebrobakken et al. 2003) MD99-2284- Depth [cm]- Age [ka BP] (this study)- N. pachyderma [%] (Bakke et al. 2009, Eldevik et al. 2014)- summer sSST 100m [°C] (this study) JM09-020- Depth [cm]- Age [ka BP] (this study)- annual SST [°C] (Łącka et al. 2019) SupplementaryFigure1.pdf shows Age-depth relationships of cores used in the study as modeled using a Bayesian approach with the Bacon software (Blaauw and Christen, 2011). Dark shading indicates the more likely ages for a given depth, the grey dashed line indicates the 95% confidence range, and the red dashed line indicates the best-fit (mean) age model. SupplementaryFigure2.pdf shows Sea-ice concentration in (A) 6.83-6.85 ka BP and (B) 7.63-7.65 ka BP in the TraCE-21ka. Subsurface (92 m) temperature in (C) 6.81-6.83 ka BP and (D) 7.63-7.65 ka BP in the TraCE-21ka.

SupplementaryTable1.xlsx 列出了本研究用于计算区域储层校正的全部样品。 SupplementaryTable2.xlsx 收录了本研究所用全部岩芯的单颗放射性碳测年(radiocarbon dating)信息,包括实验室编号(LabID)、深度[cm]、14C年龄±误差、校准年龄(Calibrated age,95%置信区间与均值)以及测年物种。请注意,本研究采用贝叶斯方法(Bayesian approach)构建了年龄-深度关系模型,因此校准年龄可能与单独对单颗放射性碳年龄进行校准所得结果存在差异。 SupplementaryTable3.xlsx 包含本研究所用的全部数据: OCE2017-GR02:- 深度[cm] - 年龄[ka BP](本研究测得)- 厚壁新方球虫(N. pachyderma)占比[%](Telesiński等,2022)- 夏季100米层次表层海温[°C](本研究测得) MSM5-5-723:- 深度[cm] - 年龄[ka BP](本研究测得)- 厚壁新方球虫(N. pachyderma)占比[%](Werner等,2015)- 夏季100米层次表层海温[°C](本研究测得)- PBIP25指标(Werner等,2015)- 浮游有孔虫(Planktic foraminifera)破碎率[%](Werner等,2003) JM10-330GC:- 深度[cm] - 年龄[ka BP](本研究测得)- 厚壁新方球虫(N. pachyderma)占比[%](Consolaro等,2018)- 夏季100米层次表层海温[°C](本研究测得)- 浮游有孔虫丰度[个/克](Consolaro等,2018) MSM5-5-712:- 深度[cm] - 年龄[ka BP](本研究测得)- 厚壁新方球虫(N. pachyderma)占比[%](Werner等,2013)- 夏季100米层次表层海温[°C](本研究测得)- 冰筏碎屑通量(IRD flux)[#/cm²/kyr](Werner等,2013,已重新计算以适配新年龄模型)- PBIP25指标(Müller等,2012) M23258:- 深度[cm] - 年龄[ka BP](本研究测得)- 厚壁新方球虫(N. pachyderma)占比[%](Sarnthein等,2003)- 夏季100米层次表层海温[°C](本研究测得)- 年际海表面温度(Sea Surface Temperature, SST)[°C](Martrat等,2003) M17730-4:- 深度[cm] - 年龄[ka BP](本研究测得)- 厚壁新方球虫(N. pachyderma)占比[%](Telesiński等,2015)- 夏季100米层次表层海温[°C](本研究测得)- 浮游有孔虫丰度[个/克](Telesiński等,2015) MD95-2011:- 深度[cm] - 年龄[ka BP](本研究测得)- 厚壁新方球虫(N. pachyderma)占比[%](Risebrobakken等,2003)- 夏季100米层次表层海温[°C](本研究测得)- 浮游有孔虫丰度[个/克](Risebrobakken等,2003) MD99-2284:- 深度[cm] - 年龄[ka BP](本研究测得)- 厚壁新方球虫(N. pachyderma)占比[%](Bakke等,2009;Eldevik等,2014)- 夏季100米层次表层海温[°C](本研究测得) JM09-020:- 深度[cm] - 年龄[ka BP](本研究测得)- 年际海表面温度(Sea Surface Temperature, SST)[°C](Łącka等,2019) SupplementaryFigure1.pdf 展示了本研究所用岩芯的年龄-深度关系模型,该模型通过Bacon软件(Blaauw与Christen,2011)采用贝叶斯方法构建。图中深色阴影代表特定深度对应的最概然年龄,灰色虚线代表95%置信区间,红色虚线代表最优拟合(均值)年龄模型。 SupplementaryFigure2.pdf 展示了TraCE-21ka数据集下(A)6.83至6.85 ka BP与(B)7.63至7.65 ka BP时段的海冰浓度,以及(C)6.81至6.83 ka BP与(D)7.63至7.65 ka BP时段的92米次表层水温(Subsurface temperature)。
