Experimental and Numerical Investigation of Hydrodynamic Characteristics of Aquaculture Nets: The Critical Role of Solidity Ratio in Biofouling Assessment

Computation
Biofouling on aquaculture netting increases hydrodynamic drag and restricts water exchange across net cages. The solidity ratio is introduced as a quantitative parameter to characterize fouling severity.

Theoretical models for compressible vortex dynamics [PDF]

, 2017
In this thesis, we study the effects of weak compressibility on staggered vortex streets, which are a ubiquitous phenomenon observed in nature. They are formed by fluid flowing past an obstacle, and can be found at several different length scales ranging

Thorncliffe Formation: A proglacial to subglacial lacustrine basin sequence, Greater Toronto Region, Canada

Boreas, Volume 55, Issue 3, Page 717-750, July 2026.
Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

Boreas, Volume 55, Issue 3, Page 866-884, July 2026.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

Combined EISCAT radar and optical multispectral and tomographic observations of black aurora [PDF]

, 2008
Black auroras are recognized as spatially well-defined regions within a uniform diffuse auroral background where the optical emission is significantly reduced.

Dusty vortex streets in Saturn's rings [PDF]

, 1996
It is shown that the equations governing the electromagnetic equilibrium of moving charged dust grains admit vortex street solutions. The latter should be useful in understanding the salient features of coherent nonlinear structures that have been ...

Weichselian history of the Fennoscandian Ice Sheet centre, Kvarken archipelago, western Finland—flow shifts, thermal regime and deglaciation

Boreas, Volume 55, Issue 3, Page 670-701, July 2026.
Rapid thaw of the Earth's cryosphere in response to anthropogenic warming highlights the need to identify and understand the contrasting signatures of past ice‐sheet stability and collapse. The Kvarken archipelago, western Finland, at the centre of the former Fennoscandian Ice Sheet (FIS), has been designated a UNESCO World Heritage site in recognition
