dramatic channel changes when viewed against the river’s longer-term Holocene history. In this paper, new measurements of the Macdonald River’s channel morphology are used to resolve the river’s evolution in the ∼ 50 years since these major channel-altering floods. By 2002, the Macdonald River’s bed had narrowed
1 sty 2015 · The Holocene climate history showed three stages of natural climate oscillations in the Baltic Sea region: short-term cold episodes related to deglaciation during a stable positive temperature trend (11,000–8000 cal year BP); a warm and stable climate with air temperature 1.0–3.5 °C above modern levels (8000–4500 cal year BP), a ...
26 sie 2012 · The early Holocene is the most recent portion of Earth history with rapid ice-sheet retreat and sea-level rise under interglacial climate conditions, and, as such, relevant in the context of...
12 sty 2012 · Here we provide new well-dated constraints on the deglaciation history, and changes in sea ice and climate based on analyses of sedimentological proxies, diatoms and fossil pigments in a sediment core collected from an isolation basin on Beak Island in Prince Gustav Channel, NE Antarctic Peninsula (63°36′S, 57°20′W).
25 paź 2024 · Holocene Epoch - Coastal Ecosystems, Sea Level Rise, Climate Change: It was recognized as early as 1842 that a logical consequence of a glacial age would be a large-scale withdrawal of ocean water. Consequently, deglaciation would produce a postglacial “glacioeustatic” transgression of the seas across the continental shelf.
Online exhibits: Geologic time scale: Cenozoic Era. The Holocene Epoch. To observe a Holocene environment, simply look around you! The Holocene is the name given to the last 11,700 years* of the Earth's history — the time since the end of the last major glacial epoch, or "ice age."
25 paź 2024 · Holocene Epoch, younger of the two formally recognized epochs that constitute the Quaternary Period and the latest interval of geologic time, covering approximately the last 11,700 years of Earth’s history.
