“…SWE estimates are of more interest for resource assessment and hydrological modeling, but in situ observations of SWE from snow pillows or transects from snow courses are few, sparse, and discontinuous, providing limited capabilities to analyze and interpret annual distribution and evolution of snow through time [22,23]. The single longest continuous record of snow depth, density, and other properties of the snowpack was collected at Hvervellir, in the central highlands, from 1965 until 2004, when the site was upgraded to automatic measurements and snow observations decommissioned [24].…”

Efficient water resource management in glacier- and snow-dominated basins requires accurate estimates of the snow water equivalent (SWE) in late winter and spring and melt onset timing and intensity. To understand the high spatio-temporal variability of snow and glacier ablation, a spatially distributed energy balance model combining satellite-based retrievals of albedo and snow cover was applied. Incoming short-wave energy, contributing to daily estimates of melt energy, was constrained by remotely sensed surface albedo for snow-covered surfaces. Fractional snow cover was used for non-glaciated areas, as it provides estimates of snow cover for each pixel to better constrain snow melt. Thus, available daily estimates of melt energy in a given area were the product of the possible melt energy and the fractional snow cover of the area or pixel for non-glaciated areas. This provided daily estimates of melt water to determine seasonal snow and glacier ablation in Iceland for the period 2000–2019. Observations from snow pits on land and glacier summer mass balance were used for evaluation, and observations from land and glacier-based automatic weather stations were used to evaluate model inputs for the energy balance model. The results show that the interannual SWE variability was generally high both for seasonal snow and glaciers. For seasonal snow, the largest SWE (>1000 mm) was found in mountainous and alpine areas close to the coast, notably in the East- and Westfjords, Tröllaskaga, and in the vicinity of glacier margins. Lower SWE values were observed in the central highlands, flatter inland areas, and at lower elevations. For glaciers, more SWE (glacier ablation) was associated with lower glacier elevations while less melt was observed at higher elevations. For the impurity-rich bare-ice areas that are exposed annually, observed SWE was more than 3000 mm.

Ágrip Inngangur: Um fjórðungur barna sem greinist með krabbamein deyr vegna sjúkdóms síns eða meðferðartengdra fylgikvilla. Tilgangur rannsóknarinnar var að kanna lifun og dánarorsakir barna sem greinst hafa með krabbamein á Íslandi. Aðferðir: Rannsóknin var afturskyggn, lýðgrunduð og náði til allra einstaklinga yngri en 18 ára sem greindust með krabbamein á Íslandi frá upphafi árs 1981 til loka ársins 2006. Upplýsingum var safnað frá Krabbameinsskrá Íslands, sjúkraskrám og Hagstofu Íslands. Niðurstöður: Á rannsóknartímabilinu greindust 279 börn með krabbamein á Íslandi. Af þeim voru 215 á lífi í lok árs 2008. Á tímabilinu var fimm ára lifun 81,2% og 10 ára lifun 76,7%. Ekki var marktaekur munur á lifun milli kynja, greiningartímabila, aldurs eða búsetu. Gaeti það skýrst af smaeð þýðisins. Lifun var mismunandi eftir krabbameinstegundum. Ellefu einstaklingar greindust síðar með meðferðartengd krabbamein, átta þeirra létust. Sextán þeirra 64 sem létust voru í laeknandi meðferð fram að andláti. Var dánarorsök meðferðartengdir fylgikvillar hjá 12 úr þeim hópi. Ályktun: Horfur barna og unglinga á Íslandi með krabbamein eru sambaerilegar við önnur vestraen ríki. Horfur eru mun verri í meðferðartengdum krabbameinum samanborið við frumkrabbamein. Meðferðartengdir fylgikvillar eru algengasta dánarorsök ef krabbameinsmeðferð er gefin með laeknanlegum tilgangi.
