A Narwhal in the Thames Estuary [PDF]
THE recent stranding of a narwhal (Monodon monoceros) at Rainham, Essex, is a record of considerable interest. This species is usually limited to Arctic waters, although it occasionally penetrates into the North Sea. The infrequency of its occurrence off the British coast may be gauged by the fact that since 1588, when one was found on the coast of ...

Ethical ecotourists: the narwhal dilemma revisited [PDF]
Studying the ethical philosophies of individual travellers is a valid field of research, but there are practical difficulties in defining an industry subsector in terms of the intentions of its customers. Concerns over the conservation of endangered species may conflict with equally principled concerns over the rights and responsibilities of Indigenous

Studies of the inner shelf and coastal sedimentation environment of the Beaufort Sea from ERTS-A [PDF]
The author has identified the following significant results. Shearing periodically occurs between the westward moving pack ice (3 to 10 km/d) within the Pacific Gyre and the fast ice along the coast, forming major grounded shear and pressure ridges ...

Seismo-Stratigraphy and Sedimentology of Holocene Sediments off Grande Rivière de la Baleine, Southeastern Hudson Bay, Québec [PDF]
The regional distribution of Holocene sediments of eastern Hudson Bay off the Grande Rivière de la Baleine mouth was mapped using a grid of reflection seismic lines (approximately 300 km long and covering an area of approximately 800 km2) and data from 7

Space‐use strategies drive diet composition of Baffin Bay polar bears
Polar bears (Ursus maritimus) depend on sea ice to hunt their ice‐associated prey. However, climate‐induced sea ice loss is leading to changes in space‐use strategies of polar bears, with bears in some subpopulations spending more time on land or ...

Research highlight: how to cage a unicorn—confining light in a tiny volume
Overcoming the diffraction limit in optics is challenging and demands a profound understanding of light behavior under extreme confinement. The newly developed framework, termed singulonics, demonstrates the formation of sub-diffraction limit narwhal ...

Singulonics: narwhal-shaped wavefunctions for sub-diffraction-limited nanophotonics and imaging
The diffraction limit, rooted in the wave nature of light and formalized by the Heisenberg uncertainty principle, imposes a fundamental constraint on optical resolution and device miniaturization.

Evidence of a narwhal (Monodon monoceros) summer ground in Nares Strait
Our limited knowledge of the marine mammal fauna in northernmost Greenland and Canada, specifically north of 80°N, relies largely on opportunistic observations collected during expeditions with different objectives.
