The Fe-Mn oxyhydroxide fraction in marine pelagic sediments is an ideal archive for this purpose because seawater-derived trace metals such as neodymium (Nd), hafnium (Hf) and lead (Pb) can be chemically extracted from this fraction. This archive was already successfully used in earlier studies for the reconstruction of the seawater Nd isotope evolution in the South Atlantic, but no such record at sub-millennial resolution exists for the North Atlantic. For Hf and Pb isotopes, not a single record using the Fe-Mn oxyhydroxide fraction exists to date. Especially Hf and Pb isotopes in seawater, however, potentially yield valuable information about short-term climatic changes, intensity of glaciation and the prevailing weathering regime on the continents. Therefore, using seawater-derived Hf and Pb isotopes in conjunction with Nd isotopes from the same seawater-derived fraction allow determining the provenance of a water mass and the climatic conditions prevailing at the continental source area.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Marcus Gutjahr\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 383813351X\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783838133515\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Sudwestdeutscher Verlag Fur Hochschulschrifte\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 06\/19\/2012\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 188\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.62lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.43d","brand":"Marcus Gutjahr","offers":[{"title":"Paperback","offer_id":44126047895807,"sku":"9783838133515","price":96.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_0b9c5f4f-d35b-49b3-9189-5e56167314a2.jpg?v=1687445989","url":"https:\/\/www.whiterainbookhouse.com\/products\/tracing-ocean-circulation-and-weathering-marcus-gutjahr-9783838133515","provider":"WR Book House","version":"1.0","type":"link"}
