Quantifying glacier melt enhancement due to dust deposition during the 2022 melt season. Tungnaárjökull glacier, South Iceland
… event occurred over the southwest outlets of Vatnajökull ice cap during early July of 2022 causing surface darkening. To investigate the impact of the dust event on the melt season SMB, this study used automatic weather station (AWS) data from three different sites on Tungnaárjökull glacier, a …

National Park Explorer
… solution we built an example exhibition of the Vatnajökull National Park where it’s possible to interact with a 3D map using touch input to explore and experience the national park in an engaging and interesting way. In this report we outline the functionalities of our solution as well as our …

Holocene development of Lake Lögurinn and Eyjabakkajökull : a multi-proxy approach
… of Icelandic glaciers, including the large Vatnajökull ice cap and its outlet glaciers, is not fully known. In this thesis, a sediment sequence covering the past 10 500 years from Lake Lögurinn in eastern Iceland has been analysed. This glacier-fed lake currently receives meltwater and …

Insights into marine biological responses to Icelandic glacial outburst floods from remote sensing data
… cauldrons and Grímsvötn volcano beneath the Vatnajökull ice cap, SE Iceland (64.4220° N, 16.7902° W) at least since 1940. Jökulhlaup (glacial outburst floods) frequency has increased but their magnitude has decreased. This study examines jökulhlaup effects on the marine environment at the …

Towards monitoring volcanoes in Iceland and Hawai’i with seismic velocity variations
… pairs across the network. I locate tremor under Vatnajökull glacier, associated with small sub-glacial eruptions, and at the main vents in the Holuhraun lava field. I comprehensively explain variations in dv/v arising from diverse crustal stresses, including those from magmatic pressurisation and …

The structure and seismicity of Icelandic rifts
… anomalies are seen in the north-west of the Vatnajökull icecap, at the location of thickest crust and inferred centre of the underlying mantle plume. Inversion for shear wave velocity structure shows high velocity-gradients in the top 10 km, defining a thickened extrusive upper crust in …

Weathering and riverine fluxes in pristine and controlled river catchments in Iceland
… the dam (Kárahnjúkar) in the highlands East of Vatnajökull ice cap was from 2004 to 2007. An initial baseline study of Jökulsá á Dal, prior to dam construction, was conducted from 1998 to 2003 in order to constrain the natural discharge regime and fluxes of suspended- and dissolved material. …

Rheological response to tectonic and volcanic deformation in Iceland
… in the WVZ, 14.0 ± 2 mm/yr (between south of Vatnajökull glacier and Torfajökull volcanic system) in the EVZ, and 18.4 ± 1.5 mm/yr (crossing Fremri Námur volcanic system) in the NVZ. The widths of the deformation zones along those profiles are ~50 km in the WVZ, ~100 km in the EVZ, and ~56 km …
