New Zealand Geographer, Volume 82, Issue 3, December 2026.ABSTRACT In a move away from exclusive use by modality, a number of shared tramping and mountain biking tracks have been developed in New Zealand. We ask: On shared tracks, what tensions arise and how are they experienced? Using data from online surveys of track‐users, we examine bikers' and trampers' perspectives and experiences of conflict.

Transactions of the Institute of British Geographers, Volume 51, Issue 4, December 2026.Short Abstract This paper contributes to conceptual debates on ruins by generating novel insights into how encounters with the haunted materialities of ruins in the field inform (post)colonial trajectories of exploration. Empirically, it examines how material and spectral traces of past lives in the field, alongside play with categories of absence and ...

Considerations to the Probabilities of Collision of Ships by a Model of Collision Avoiding System
The Journal of Japan Institute of Navigation, 1973 An improved model of a collision avoiding system in the present paper was represented by two parameters called the intensity and the Allowance of Collision Avoiding Maneuvers, of which the practical meanings of ship nandling were discussed. The model was applied to ships navigating through the ten narrow channels in Japan in order to study the ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.Abstract Atmospheric mineral dust and black carbon (BC) aerosols play important roles in the Earth's climate system, yet direct observations over the Southern Ocean (SO) are scarce. In this study, we present the characteristics of airborne water‐insoluble particles (WIPs) collected during a cruise of the R/V Shirase in the Australian and Indian sectors
