Paleocene-Eocene volcanic segmentation of the Norwegian-Greenland seaway reorganized high-latitude ocean circulation

Communications Earth & Environment, 2021
Uplift and volcanism drove fragmentation of the Norwegian-Greenland seaway, which may have restricted Arctic-Atlantic exchange during the Paleocene-Eocene Thermal Maximum, according to sedimentological, paleontological and seismic analyses from NE ...

Transitions of social-ecological subsistence systems in the Arctic [PDF]

, 2017
Transitions of social-ecological systems (SES) expose governance systems to new challenges. This is particularly so in the Arctic where resource systems are increasingly subjected to global warming, industrial development and globalization which ...

Shaping the human face: Periosteal bone modeling across ontogeny

The Anatomical Record, EarlyView.
Abstract Facial morphology is a defining aspect of Homo sapiens that distinguishes our species from fossil ancestors and plays a central role in estimating age, sex, and ancestry in both past and present populations. Understanding how the face develops during postnatal ontogeny is essential for interpreting adult facial variation.

A first constraint on basal melt-water production of the Greenland ice sheet

Nature Communications, 2021
Melting at the base of the Greenland Ice Sheet is often disregarded as a source of quantifiable mass loss. In this study, the authors find the basal mass loss is equivalent to 8% of the ice sheet’s present imbalance, and that the loss of mass from basal ...

Monitoring for seismological and geochemical groundwater effects of high-volume pumping of natural gas at the Stenlille underground gas storage facility, Denmark

GEUS Bulletin, 2021
The large natural gas storage facility at Stenlille, Denmark, has been monitored to investigate the effect of pumping large amounts of gas into the subsurface. Here, we present a new dataset of microseismicity at Stenlille since 2018.

Impact of ocean stratification on submarine melting of a major Greenland outlet glacier [PDF]

, 2011
Submarine melting is an important balance term for tidewater glaciers1,2 and recent observations point to a change in the submarine melt rate as a potential trigger for the widespread acceleration of outlet glaciers in Greenland3-5.

Ontogenetic changes and sexual dimorphism in the cranium and mandible of the Atlantic walrus (Odobenus rosmarus rosmarus L.)

The Anatomical Record, EarlyView.
Abstract Walruses have been an important subsistence and cultural resource for humans and have been exploited for millennia across their distribution. This exploitation has contributed to severe declines in several populations and local extirpations.

Sedimentation and subsidence history of the Lomonosov Ridge [PDF]

, 2006
During the first scientific ocean drilling expedition to the Arctic Ocean (Arctic Coring Expedition [ACEX]; Integrated Ocean Drilling Program Expedition 302), four sites were drilled and cored atop the central part of the Lomonosov Ridge in the Arctic ...

The absent presence of disability in British higher education

British Educational Research Journal, EarlyView.
Abstract Rates of disability disclosure are steadily increasing in British higher education (HE), with 18% of the student population having a known disability in 2023/24. It might be assumed that progress is being made with increased representation, rights and support for disabled students.

Tusk anomalies in narwhals (Monodon monoceros) from Greenland

Polar Research, 2022
The elongated, spiraled tusk of male narwhals (Monodon monoceros) grows continuously throughout the life of the whale and is most likely a secondary sexual trait used in male–male hierarchical competition and possibly in female mate choice.
