High-resolution Sr-isotopic evolution of Black Sea water during the Holocene: Implications for reconnection with the global ocean

Abstract

Abstract The 10\u202fm-thick Holocene succession at core site M02-45 (41°41.17′N, 28°19.08′E, −69\u202fm water depth) has key advantages for investigation of the Sr-isotopic evolution of the Holocene Black Sea. Earlier studies have focussed on thinner successions and coquinas. At the M02-45 site (augmented by nearby core M05-03P), 87Sr/86Sr determinations on mollusc shells extracted at mostly 10–20\u202fcm depth increments provide a temporal resolution mostly
