Volcanic ash retrieved from the GRIP ice core is not from Thera

چکیده
[2] The date of the eruption of the volcano Thera (Santorini), Greece, during the Minoan archaeological period in the second millennium BC, has been much debated. There have been tens of research papers [e.g., Warren, 1984; Hammer et al., 1987; Baillie and Munro, 1988; Zielinski and Germani, 1998a, 1998b; Wiener, 2003] and at least two books [Hardy and Renfrew, 1990; Manning, 1999] devoted to the eruption date. The date has generated such debate because of its potential for resolving Ancient Near Eastern chronology. Hammer et al. [2003]—hereinafter ‘‘the H report’’—have presented tephra (i.e., volcanic ash) found in the GRIP (Greenland Ice core Program) ice core, from Greenland. The H report claims that this tephra is from Thera. If the claim were true, then the eruption would be dated (because the layer of ice in which the tephra was found dates the corresponding eruption). The present work considers the claim.

Bristlecone pine tree rings and volcanic eruptions over the last 5000 yr
Many years of low growth identified in a western USA regional chronology of upper forest border bristlecone pine (Pinus longaeva and Pinus aristata) over the last 5000 yr coincide with known large explosive volcanic eruptions and/or ice core signals of past eruptions. Over the last millennium the agreement between the tree-ring data and volcano/ice-core data is high: years of ring-width minima ...
متن کاملA model sensitivity study of the impact of clouds on satellite detection and retrieval of volcanic ash
Volcanic ash is commonly observed by infrared detectors on board Earth-orbiting satellites. In the presence of ice and/or liquid-water clouds, the detected volcanic ash signature may be altered. In this paper the sensitivity of detection and retrieval of volcanic ash to the presence of ice and liquid-water clouds was quantified by simulating synthetic equivalents to satellite infrared images wi...
متن کاملHeterogeneous Ice Nucleation by Soufriere Hills Volcanic Ash Immersed in Water Droplets
Fine particles of ash emitted during volcanic eruptions may sporadically influence cloud properties on a regional or global scale as well as influencing the dynamics of volcanic clouds and the subsequent dispersion of volcanic aerosol and gases. It has been shown that volcanic ash can trigger ice nucleation, but ash from relatively few volcanoes has been studied for its ice nucleating ability. ...

[1] We present a new method for inferring the relative location (lowversus high-southern latitude), and therefore the potential climatic impact, of past eruptions based on the particle size distribution (PSD) of micrometer-sized ash measured continuously in the West Antarctic Ice Sheet (WAIS) Divide ice core. We find that particles from a high-southern latitude eruption (Buckle Island, Antarcti...
متن کاملIce nucleation and overseeding of ice in volcanic clouds
[1] Water is the dominant component of volcanic gas emissions, and water phase transformations, including the formation of ice, can be significant in the dynamics of volcanic clouds. The effectiveness of volcanic ash particles as ice-forming nuclei (IN) is poorly understood and the sparse data that exist for volcanic ash IN have been interpreted in the context of meteorological, rather than vol...
