Samples with a dry weight of approximately 10 g were wet sieved using a 150 μm and 63 μm sieves. Coarse fraction >150 μm was decarbonized using 10% HCl, washed using distilled water, and dried. The ratio of weight percentage for the decarbonized coarse fraction (150–2,000 µm) relative to the weight of the dried bulk sediment were used as IRD. This is consistent with the commonly used size fraction > 150 μm for delimiting IRD (Hemming, 2004). Data in the intervals of the visible tephra layers were excluded from the IRD record because this material was delivered into sediment through the atmosphere, rather than by ice and, therefore, is not IRD. Need to understand that the nearby Kamchatka peninsula is area of active volcanism. Therefore, the determined IRD values (wt % of decarbonated fraction 150-2,000 µm) may include as terrigenous particles as volcanic particles, which were earlier fallout of the land during explosive volcanic eruptions, captured by sea ice and icebergs from the coast and land and then transferred into core location by water currents. 167.262 167.262 51.567 51.567 167.262 51.567 2016-08-01T00:27:00 2016-08-01T00:27:00 0.0 5.57 vertical profile LV76-21 51.567 167.262 -2769.0 2016-08-01T00:27:00 LV76 Gorbarenko, Sergey A 2016-07-16 2016-08-17 Akademik M.A. Lavrentyev Gravity corer GC 558 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ DEPTH, sediment/rock Depth sed m depth http://purl.obolibrary.org/obo/PATO_0001595 sediment http://purl.obolibrary.org/obo/ENVO_00002007 rock Length L http://dbpedia.org/resource/Length Gorbarenko Sergey A gorbarenko@poi.dvo.ru 0000-0001-8864-0499 Depth sed [m] Size fraction > 0.063 mm, sand >63 µm % size http://purl.obolibrary.org/obo/PATO_0000117 Fraction sand Dimensionless Ratio ψ Grain size, sieving Gorbarenko Sergey A gorbarenko@poi.dvo.ru 0000-0001-8864-0499 >63 µm [%] CurationLevelC Enhanced curation https://wiki.pangaea.de/wiki/Curation_levels citable AMS 14C ages Benthic and planktonic foraminifera Detroit Seamount IRD LV76-21 Magnetic susceptibility productivity proxies author27671 author94316 author94318 author97695 basis105 campaign49255 curlevel30 event3036158 geocode1 geocode1599 geocode1600 geocode1601 geocode8128 license21 method11107 method65 param1555 pi27671 term1073131 term1073204 term38263 term41056 term42093 term43794 term43863 term44034 term47597 term48140 term67292 term71965 term71966 term71967 term818 topotype3
