From the comparison between these profiles, a dominant contribution of sulphuric acid to the ionic balance of Antarctic ice for the Holocene was confirmed. A progressive increase with depth was observed for chloride concentrations, showing a change of relative contribution between sulphate and chloride. A higher increase of chloride was evident between 270 and 360 m depth, probably due to a change in source or transport processes or to an increase of the annual snow-accumulation rate. The DEP, ECM and sulphate ice signatures of Tambora (AD 1816) and El Chichon (?) (AD 1259) eruptions are described in detail. A characteristic peak series, due to HCl deposition, was identified at 103\u2013109 m depth from the ECM, DEP and chloride profiles.", "doi": "10.3189/172756400781820750", "keywords": [ "NEANIAS Atmospheric Research Community", "Earth-Surface Processes" ], "language": "eng", "license": { "id": "other-open" }, "notes": "", "publication_date": "2000-01-01", "relations": { "version": [ { "count": 1, "index": 0, "is_last": true, "last_child": { "pid_type": "recid", "pid_value": "121925" }, "parent": { "pid_type": "recid", "pid_value": "121924" } } ] }, "resource_type": { "subtype": "article", "title": "Journal article", "type": "publication" }, "title": "Holocene electrical and chemical measurements from the EPICA\u2013Dome C ice core" }, "owners": [ 14 ], "revision": 1, "stats": { "downloads": 0.0, "unique_downloads": 0.0, "unique_views": 0.0, "version_downloads": 0.0, "version_unique_downloads": 0.0, "version_unique_views": 0.0, "version_views": 0.0, "version_volume": 0.0, "views": 0.0, "volume": 0.0 }, "updated": "2023-09-27T14:45:48.830889+00:00" }
