Hydrology of a Polythermal Glacier, Erikbreen, Northern Spitsbergen

Hydrology Research, 1995
Glacial and glaciohydrologic processes that control the glaciofluvial sediment delivery from Erikbreen, a polythermal glacier on the north coast of Spitsbergen (79°40'N, 12°30'E), were studied during the summer seasons of 1990,1991 and 1992. Erikbreen differs from most glaciers of similar size in Svalbard, by the high flow velocity and a heavily ...

Authoring Terrestrial Planets with Diffusion Models

Computer Graphics Forum, EarlyView.
Abstract To support the design and subsequent generation of terrestrial planets for use in the creative media, we propose a solution that employs a generative model trained on satellite data from planetary bodies with a defined solid surface, such as the Earth and Mars.

A large sample analysis of European rivers on seasonal river flow correlation and its physical drivers [PDF]

, 2019
The geophysical and hydrological processes governing river flow formation exhibit persistence at several timescales, which may manifest itself with the presence of positive seasonal correlation of streamflow at several different time lags. We investigate

An experimental examination of dispersal decisions made by flight‐capable heteropteran insects in urban stormwater pond conditions

Ecological Entomology, EarlyView.
Salty conditions in urban stormwater ponds can influence dispersal timing in species‐specific ways for actively dispersing aquatic heteropteran insects. Assaying multiple aspects of dispersal propensity, Hesperocorixa obliqua emigrated earlier in stormwater pond conditions while overall probabilities remained unchanged; Notonecta undulata emigration ...

Tracking extinct glaciers in GLIMS

Annals of Glaciology
Global Land Ice Measurements from Space (GLIMS), an initiative to build and distribute a database of global glacier data, has recently begun to track glaciers that have recently disappeared.

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

Fisheries Management and Ecology, EarlyView.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Priority areas for arthropod conservation in the Iberian Peninsula and Balearic Islands: Insights from a multi‐taxon distributional database

Insect Conservation and Diversity, EarlyView.
Using over 416,000 occurrence records from 13 arthropod groups (6233 arthropod species), we mapped large‐scale richness patterns and identified biodiversity hotspots across the Iberian Peninsula and Balearic Islands. Hotspot congruence among arthropod groups was low, underscoring the importance of integrative, multi‐taxon approaches for conservation ...

Warm proglacial lake temperatures and thermal undercutting enhance rapid retreat of an Arctic glacier [PDF]

The Cryosphere
Determining the characteristics of Arctic proglacial lakes is essential for understanding their current and future influence on glacier mass loss, capacity as a carbon sink and the associated impacts for downstream hydrology and ecology.

Hydrology and Glaciers in the Upper Indus Basin [PDF]

, 2013
Examines the state of the science associated with the snow and ice hydrology in the Upper Indus Basin (IUB), reviewing the literature and data available on the present and projected role of glaciers, snow fields, and stream flow. Considerable speculation but little analysis exists concerning the importance of glaciers in the volume and timing of flow ...

Demonstration of an instream flow model to accommodate a threatened tiger beetle in riverine dune habitat

Insect Conservation and Diversity, EarlyView.
Burrows of the threatened Gibson's Big Sand Tiger Beetle in riverine dune habitats are susceptible to flooding through managed flows. HEC‐RAS modelling identified the flow thresholds above which flooding would occur for burrows and affect the beetle larvae. These findings provide instream flow guidelines for conserving this threatened species and guide
