Supplementary Data for: Worldwide consequences of a mid-Holocene cold event in the Nordic Seas

<p>SupplementaryTable1.xlsx lists all the samples used to calculate the regional reservoir correction.</p> <p>SupplementaryTable2.xlsx lists all information on the individual radiocarbon dates of all the cores used in the study: LabID, Depth [cm], 14C age &plusmn; 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.</p> <p>SupplementaryTable3.xlsx contains all the data used in the study:</p> <p>OCE2017-GR02:<br>- Depth [cm]&nbsp;<br>- Age [ka BP]&nbsp;(this study)<br>- <em>N. pachyderma </em>[%] (Telesiński et al. 2022)<br>- summer sSST 100m [&deg;C] (this study)</p> <p>MSM5-5-723:<br>- Depth [cm]<br>-&nbsp;Age [ka BP] (this study)<br>- <em>N. pachyderma</em>&nbsp;[%] (Werner et al. 2015)<br>- summer sSST 100m [&deg;C] (this study)<br>-&nbsp;P_BIP₂₅ (Werner et al. 2015)<br>- Planktic foraminifera fragmentation [%] (Werner et al. 2003)</p> <p>JM10-330GC:<br>- Depth [cm]<br>-&nbsp;Age [ka BP] (this study)<br>- <em>N. pachyderma </em>[%] (Consolaro et al. 2018)<br>- summer sSST 100m [&deg;C] (this study)<br>-&nbsp;Planktic foraminifera [ind./g]&nbsp;(Consolaro et al. 2018)</p> <p>MSM5-5-712:<br>- Depth [cm]<br>-&nbsp;Age [ka BP] (this study)<br>- <em>N. pachyderma </em>[%] (Werner et al. 2013)<br>- summer sSST 100m [&deg;C] (this study)<br>- IRD flux [#/cm**2/kyr] (Werner et al. 2013, recalculated to the new age model)<br>- P_BIP₂₅(M&uuml;ller et al. 2012)</p> <p>M23258:<br>- Depth [cm]<br>-&nbsp;Age [ka BP] (this study)<br>- <em>N. pachyderma </em>[%] (Sarnthein et al. 2003)<br>- summer sSST 100m [&deg;C] (this study)<br>-&nbsp;annual SST [&deg;C] (Martrat et al. 2003)</p> <p>M17730-4<br>- Depth [cm]<br>-&nbsp;Age [ka BP] (this study)<br>- <em>N. pachyderma </em>[%] (Telesiński et al. 2015)<br>- summer sSST 100m [&deg;C] (this study)<br>-&nbsp;Planktic foraminifera [ind./g]&nbsp;(Telesiński et al. 2015)</p> <p>MD95-2011<br>- Depth [cm]<br>-&nbsp;Age [ka BP] (this study)<br>- <em>N. pachyderma </em>[%] (Risebrobakken et al. 2003)<br>- summer sSST 100m [&deg;C] (this study)<br>-&nbsp;Planktic foraminifera [ind./g] (Risebrobakken et al. 2003)</p> <p>MD99-2284<br>- Depth [cm]<br>- Age [ka BP] (this study)<br>- <em>N. pachyderma </em>[%] (Bakke et al. 2009, Eldevik et al. 2014)<br>- summer sSST 100m [&deg;C] (this study)</p> <p>JM09-020<br>- Depth [cm]<br>-&nbsp;Age [ka BP] (this study)<br>-&nbsp;annual SST [&deg;C] (Łącka et al. 2019)</p> <p>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).
