magnetic susceptibility has been extensively used to determine the magnetic properties of rocks for different applications, such as hydrocarbon or mineral explorations. this magnetic quantity can be directly measured in an accurate but time-consuming operation, or it can be mathematically approximated using a reliable procedure to achieve a desired accuracy. the poisson theory is one of the mos...

Fjord-scale circulation forced by rising turbulent plumes of subglacial meltwater has been identified as one possible mechanism of oceanic heat transfer to marine-terminating outlet glaciers. This study uses buoyant plume theory and a nonhydrostatic, three-dimensional ocean–icemodel of a typical outlet glacier fjord in west Greenland to investigate the sensitivity of meltwater plume dynamics an...

Equilibrium-line altitudes (ELAs) of former glaciers in the Zardkuh Mountain of the Zagros Mountain Range were reconstructed from glacial-geologic data on former ice limits by using various methods. In the study area various types of glacial landforms such as outwash fans, moraines and well developed glacial cirques are observed. The results suggest that ELA were depressed 1433 m below to prese...

the presence of glacial deposits is among the most important evidences of quaternary climatic changes. the aalamkooh and thakht-e-solieman glaciers are the samples of those glaciers in the alborz mountains. all iranian and foreign researchers who have worked on the alamkooh glaciers believe the glaciers of northern alborz are parts of active ones in iran. the objective of this research is inves...

[1] While the impacts of long‐term climate change trends on glacier hydrology have receivedmuch attention, little has been done to quantify direct glacier runoff contributions to streamflow. This paper presents an approach for determining glacier runoff contributions to streamflow and estimating the effects of increased temperature and decreased glacier area on future runoff. We focus on late s...

The impact of the timing of dust deposition on glacier runoff was evaluated using a glacier mass–balance model with a newly improved scheme to track a dusted layer in a snow layer of a glacier. The lowering of surface albedo due to the dusted layer appearing leads to a drastic increase of glacier runoff even under the same meteorological conditions. Calculations of seasonal sensitivity, the rel...
