Description
Summary:AGAVE was a US-financed project where scientists explored life in the hydrothermal vents from the core of the Earth, which has been found at the Gakkel Ridge, a mountain ridge below the Arctic Ocean. The expedition was an International Polar Year (IPY) collaboration between scientists from the USA, Sweden, Germany and Japan. The AGAVE expedition made a number of exciting discoveries on the Gakkel Ridge, and one of the most surprising was the fact that the axial valley at the 85°E segment is blanketed in pyroclastic deposits - the largest unconsolidated deposits ever found on the seafloor (picture 4). These deposits are caused by explosive volcanic eruptions, which many scientists had assumed were impossible in the deep ocean because of the great pressures at such depths. The AGAVE observations turn this idea upside down, and demonstrate that volcanic activity at the 85°E site has been accompanied by the catastrophic discharge of magmatic volatiles. These pyroclastic deposits are being analyzed to determine ... : I juli 2007 genomfördes forskningsexpeditionen Arctic Gakkel Vents (AGAVE) med isbrytaren Oden i Arktiska oceanen. AGAVE var ett amerikanskt forskningsprojekt där man undersökte livet i de hydrotermala utlopp från jordens kärna man har hittat vid Gakkelryggen, en bergsrygg under Arktiska oceanen. Expeditionen genomfördes i samarbete mellan forskare från USA, Sverige, Tyskland och Japan inom ramen för det Internationella polaråret 2007–2008. Under AGAVE-expeditionen gjordes en mängd upptäckter, men den största är nog att axialklyftan vid 85°E på Gakkelryggen är täckt av pyroklastiska avlagringar (material från vulkanutbrott), och det är den största enskilda pyroklastiska avlagringen som någonsin hittats på havsbotten. Syfte: AGAVE-expeditionen hade två syften: ett vetenskapligt syfte som var att undersöka Gakkelryggens vulkaniska och hydrotermiska egenskaper, samt ett tekniskt syfte som var att utveckla ny teknik för forskning av istäckta hav. This data set contains meteorological, oceanographic and ship data ...
