Environmental, ecological and cultural impacts of tidal bores, benaks, bonos and burros [PDF]
, 2009 A tidal bore is a series of waves propagating upstream as the tidal flow turns to rising. It forms during the spring tide conditions when the tidal range exceeds 4 to 6 m and the flood tide is confined to a narrow funnelled estuary with low freshwater ...

The IceShark, an effective method for sampling plankton under sea ice
Limnology and Oceanography: Methods, EarlyView.Abstract Seasonal sea ice plays a crucial role in shaping coastal ecosystem dynamics throughout the circumpolar region. Of particular interest to oceanographers is the ice‐ocean interface which functions as a multidimensional habitat, supporting both sympagic algae and pelagic phytoplankton in the under‐ice surface waters.

Environmental Impact of a Tidal Bore on Tropical Rivers [PDF]
, 2002 A tidal bore impacts significantly on the estuarine ecosystem, although little is known on the flow field, mixing and sediment motion beneath tidal bores.

Field Measurements of Unsteady Turbulence in a Tidal Bore: the Garonne River in October 2013 [PDF]
, 2015 A tidal bore is an unsteady rapidly-varied open channel flow generated by the swift advance of the early flood tide in a funnel-shaped river estuary when the tidal range exceeds 4.5 to 6 m.

Limnology and Oceanography: Methods, EarlyView.Abstract Mutvei's solution is a widely utilized standard staining method for revealing growth increments in biogenic carbonates; however, it is a slightly toxic, destructive approach with varying success across species groups. Therefore, there has been growing interest in finding non‐toxic, less destructive, and straightforward alternative techniques ...

Effect of a large bed roughness on positive surge propagation in canals [PDF]
, 2016 In open channels and water supply canals, the brusque operation of control valves and gates may induce large unsteady flow motions called surges. To date, the literature has focused on the propagation of surges in smooth canals, ignoring the effects of ...

Mixing and dispersion role of tidal bores [PDF]
, 2004 When a river mouth has a flat converging shape and when the tidal range exceeds 6 to 9 m, the river may experience a tidal bore. A tidal bore is basically a positive surge propagating upstream as the tidal flow turns to rising. The occurrence of a bore has a significant impact on estuarine systems.

Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status
Nordic Journal of Botany, EarlyView.Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.

Tidal bores, Aegir, Eagre, Mascaret, Pororoca: theory and observations [PDF]
, 2012 A tidal bore is a series of waves propagating upstream as the tidal flow turns to rising. It forms during spring tide conditions when the tidal range exceeds 4 to 6 m and the flood tide is confined to a narrow funnelled estuary.

Remote Sensing in Ecology and Conservation, EarlyView.Tree canopy height is a key indicator of forest biomass and structure, yet accurate mapping across the Amazon remains challenging. Here, we generated a canopy height map of the Amazon forest at ~4.8 m resolution using Planet NICFI imagery and a deep learning U‐Net model trained with airborne LiDAR data.
