Assessing Greenland Ice Sheet meltwater losses at the pixel and drainage basin scale
No full textThe Greenland Ice Sheet (GrIS) is expected to increase its contributions to sea level rise with atmospheric warming, and it is important to accurately predict future sea level change. Surface meltwater runoff losses, modulated by surface albedo, are two dominant uncertainties in future GrIS sea level rise estimates. The first component of this study characterizes surface albedo in the lower ablation zone, a key variable controlling the surface energy and mass balance of the GrIS, and an important parameter in regional climate models (RCMs). This analysis is expanded in a second study to evaluate satellite albedo retrievals and assess its ability to resolve sub-pixel spatial variability of ablation area albedo. In situ spectral albedo data collected along a transect, Moderate Resolution Imaging Spectroradiometer (MODIS) daily albedo product, and high spatial resolution WorldView-2 (WV-2) data are utilized in these two studies. The results show that the distribution of dominant ice surface types (e.g., snow, bare ice, light-absorbing impurities, and streams) act as an additional mechanism for controlling ablation zone albedos. This can significantly impact seasonal and inter-annual changes in ablation zone albedo, and subsequent melt. These findings have important implications for current RCMs, which don’t fully integrate a seasonally evolving ice surface type’s albedo scheme. The second study demonstrates over spatially heterogeneous surfaces, such as in the ablation zone, that a multiple ‘point-to-pixel’ comparison, utilizing multiple ground albedo observations coinciding with a satellite pixel, is superior to the frequently used single ‘point-to-pixel’ comparison. This points to the significance of evaluating the spatial representativeness of ground albedo sites (e.g., automatic weather stations) prior to validation of satellite or model-derived albedos. The second component of this study quantifies meltwater runoff losses, a dominant, yet understudied term of GrIS mass loss, at the drainage-basin scale. To do this, the Modèle Atmosphérique Régionale (MAR) RCM discharge estimates are compared with proglacial river discharge observations at three drainage basins – Thule, Watson, and Nuuk – located north-to-south in west Greenland. I find that MAR poorly resolves daily discharge variability in the Nuuk and Thule basins, but is better able to capture variability at longer time averages. Model-observation agreement is reduced during peak discharge events. The model-observation discharge discrepancies are likely due to an underestimation of cloud cover, from an overestimation of downward shortwave radiation. The discrepancies of model and measurements during peak discharge events is important to understand as they are expected to occur more frequently with continued warming. In a fourth study, annual and daily peak river discharge was unprecedented at all basins in the extreme melt season of 2012. Exceptional flows in all three rivers were observed corresponding with two ice sheet wide surface melt episodes in mid- and late-July 2012. These results suggest the need to further study runoff processes at the local-, basin- and continental-scale not fully captured by current RCMs. These four studies collectively contribute information that will allow for better understanding of Greenland’s complex hydrologic system. Finally, these studies provide the framework to improve physical representation of meltwater runoff and albedo components used in RCMs to project changes in Greenland’s mass loss, and subsequent contributions to sea level rise.Ph.D.Includes bibliographical referencesby Samiah Moustaf
Evidence of Meltwater Retention within the Greenland Ice Sheet
No full textGreenland ice sheet mass losses have increased in recent decades with more than half of these attributed to surface meltwater runoff. However, the magnitudes of englacial storage, firn retention, internal refreezing and other hydrologic processes that delay or reduce true water export to the global ocean remain less understood, partly due to a scarcity of in situ measurements. Here, ice sheet surface meltwater runoff and proglacial river discharge between 2008 and 2010 near Kangerlussuaq, southwestern Greenland were used to establish sub- and englacial meltwater storage for a small ice sheet watershed (36–64 km2). This watershed lacks significant potential meltwater storage in firn, surface lakes on the ice sheet and in the proglacial area, and receives limited proglacial precipitation. Thus, ice sheet surface runoff not accounted for by river discharge can reasonably be attributed to retention in sub- and englacial storage. Evidence for meltwater storage within the ice sheet includes (1) characteristic dampened daily river discharge amplitudes relative to ice sheet runoff; (2) three cold-season river discharge anomalies at times with limited ice sheet surface melt, demonstrating that meltwater may be retained up to 1–6 months; (3) annual ice sheet watershed runoff is not balanced by river discharge, and while near water budget closure is possible as much as 54% of melting season ice sheet runoff may not escape to downstream rivers; (4) even the large meltwater retention estimate (54%) is equivalent to less than 1% of the ice sheet volume, which suggests that storage in en- and subglacial cavities and till is plausible. While this study is the first to provide evidence for meltwater retention and delayed release within the Greenland ice sheet, more information is needed to establish how widespread this is along the Greenland ice sheet perimeter.Peer reviewe
Understanding Greenland ice sheet hydrology using an integrated multi-scale approach
No full textImproved understanding of Greenland ice sheet hydrology is critically important for assessing its impact on current and future ice sheet dynamics and global sea level rise. This has motivated the collection and integration of in situ observations, model development, and remote sensing efforts to quantify meltwater production, as well as its phase changes, transport, and export. Particularly urgent is a better understanding of albedo feedbacks leading to enhanced surface melt, potential positive feedbacks between ice sheet hydrology and dynamics, and meltwater retention in firn. These processes are not isolated, but must be understood as part of a continuum of processes within an integrated system. This letter describes a systems approach to the study of Greenland ice sheet hydrology, emphasizing component interconnections and feedbacks, and highlighting research and observational needs.Peer reviewe

No full textCanadian trends in opioid-related mortality and disability from opioid use disorder from 1990 to 2014 through the lens of the Global Burden of Disease Study
No full textIntroduction: Several regions in Canada have recently experienced sharp increases in opioid overdoses and related hospitalizations and deaths. This paper describes opioid-related mortality and disability from opioid use disorder in Canada from 1990 to 2014 using data from the Global Burden of Disease (GBD) study. Methods: We used data from the GBD study to describe temporal trends (1990–2014) in opioid-related mortality and disability from opioid use disorder using common metrics: disability-adjusted life years (DALY), deaths, years of life lost (YLL) and years lived with disability (YLD). We also compared age-standardized YLL and DALY rates per 100 000 population between Canada, the USA and other regions. Results: The age-standardized opioid-related DALY rate in Canada was 355.5 per 100 000 population in 2014, which was higher than the global rate of 193.2, but lower than the rate of 767.9 in the United States. Between 1990 and 2014, the age-standardized opioid-related YLL rate in Canada increased by 142.2%, while globally this rate decreased by 10.1%. In comparison with YLL, YLD accounted for a larger proportion of the overall opioid-related burden across all age groups. Health loss was greater for males than females, and highest among those aged 25 to 29 years. Conclusion: The health burden associated with opioid-related mortality and disability from opioid use disorder in Canada is significant and has increased dramatically from 1990 to 2014. These data point to a need for public health action including enhanced monitoring of a range of opioid-related harms

Introduction
Several regions in Canada have recently experienced sharp increases in
opioid overdoses and related hospitalizations and deaths. This paper describes opioid-related
mortality and disability from opioid use disorder in Canada from 1990 to 2014
using data from the Global Burden of Disease (GBD) study.
Methods
We used data from the GBD study to describe temporal trends (1990–2014) in
opioid-related mortality and disability from opioid use disorder using common metrics:
disability-adjusted life years (DALY), deaths, years of life lost (YLL) and years lived with
disability (YLD). We also compared age-standardized YLL and DALY rates per 100 000
population between Canada, the USA and other regions.
Results
The age-standardized opioid-related DALY rate in Canada was 355.5 per
100 000 population in 2014, which was higher than the global rate of 193.2, but lower
than the rate of 767.9 in the United States. Between 1990 and 2014, the age-standardized
opioid-related YLL rate in Canada increased by 142.2%, while globally this rate
decreased by 10.1%. In comparison with YLL, YLD accounted for a larger proportion of
the overall opioid-related burden across all age groups. Health loss was greater for
males than females, and highest among those aged 25 to 29 years.
Conclusion
The health burden associated with opioid-related mortality and disability
from opioid use disorder in Canada is significant and has increased dramatically from
1990 to 2014. These data point to a need for public health action including enhanced
monitoring of a range of opioid-related harms.

Tendances canadiennes en matière de mortalité liée aux opioïdes et d’invalidité découlant d’un trouble de consommation d’opioïdes, à la lumière de l’Étude sur la charge mondiale de morbidité (1990-2014)
No full textIntroduction. Plusieurs régions du Canada ont récemment connu de brusques hausses de surdoses d’opioïdes ainsi que des hospitalisations et des décès connexes. Cet article traite de la mortalité liée aux opioïdes et de l'invalidité découlant d'un trouble de consommation d’opioïdes au Canada entre 1990 et 2014, à la lumière des données de l’Étude sur la charge mondiale de morbidité (ÉCMM). Méthodologie. Nous avons utilisé les données de l’ÉCMM pour décrire l'évolution (1990 à 2014) en matière de mortalité liée aux opioïdes et d’invalidité découlant d’un trouble de consommation d’opioïdes en calculant les années de vie ajustées du facteur invalidité (AVAI), les décès, les années de vie perdues (AVP) et les années vécues avec invalidité (AVI). Nous avons également comparé les taux d’AVP et d’AVAI pour 100 000 au Canada, aux États-Unis et dans d'autres régions. Résultats. Le taux normalisé selon l’âge d’AVAI lié aux opioïdes au Canada était de 355,5 par 100 000 en 2014, soit un taux supérieur au taux mondial de 193,2 mais inférieur au taux de 767,9 aux États-Unis. Entre 1990 et 2014, le taux normalisé selon l’âge d’AVP attribuables aux opioïdes a augmenté de 142,2 % au Canada alors qu’il a diminué de 10,1 % à l’échelle mondiale. Les AVI ont contribué à une plus grande proportion du fardeau global lié aux opioïdes que les AVP, et ce, dans tous les groupes d’âge. La perte de santé a été plus importante chez les hommes que chez les femmes, et particulièrement marquée chez les 25 à 29 ans. Conclusion. Le fardeau sur la santé dû à la mortalité liée aux opioïdes et à l’invalidité découlant d’un trouble de consommation d’opioïdes au Canada est important et s’est considérablement alourdi entre 1990 et 2014. Ces données révèlent la nécessité d’agir en santé publique, notamment par le renforcement de la surveillance des divers méfaits liés aux opioïdes
