Substrate facies monitoring is critical for the understanding of fluvial geomorphologic and ecohydraulic patterns processes. However, direct substrate measurement time-consuming subjected to data sparsity because small sample, size, limited collections within an area interest, which make it difficult capture patterns. Most new experimental studies focus on mapping based median grain size a spec...

Stereo-video scuba transects were conducted during daylight hours from June to September 2013 within a proposed marine protected area (MPA) in the Firth of Clyde, west of Scotland. More juvenile Atlantic cod Gadus morhua of fork length (LF ) range 6-11 cm were observed in substrata containing mixed gravel, including maerl, than in boulder-cobble substrata with high algal cover, or sand with low...

Sediment transport is an intrinsically stochastic process, and measurement of bed load in the environment is further complicated by the unsteady nature of river flooding. Here we present a methodology for analyzing sediment tracer data with unsteady forcing. We define a dimensionless impulse by integrating the cumulative excess shear velocity for the duration of measurement, normalized by grain...

Short-term effects of bottom trawling on a 'hard-bottom' (pebble, cobble, and boulder) seafloor were studied on the outer continental shelf in the eastern Gulf of Alaska. Eight sites were trawled in August 1996; then, from a research submersible we videotaped each trawl path and a nearby reference transect to obtain quantitative data. Boulders were displaced, and large epifaunal invertebrates w...

The experience of older adults who play video games illustrates the con­temporary challenges ageing and strategies that individuals set up to navigate them. ethnography a game workshop ded­icated in French cultural centre offers an opportunity examine how group 15 women aged 60–82 years exert their agency as technogenarians (Joyce & Loe 2011). In order fully engage play, workshop’s particip...

Yuchanyan Cave in Daoxian County, Hunan Province (People's Republic of China), yielded fragmentary remains of 2 or more ceramic vessels, in addition to large amounts of ash, a rich animal bone assemblage, cobble and flake artifacts, bone tools, and shell tools. The artifacts indicate that the cave was a Late Paleolithic foragers' camp. Here we report on the radiocarbon ages of the sediments bas...

Writing in Environmental Health Perspectives (2005), Booth and Zeller [hereafter BZ05] embark on the highly ambitious task of applying ecosystem modeling to the difficult problem of tracing the flow of methylmercury (MeHg) the biologically active, potentially toxic form of mercury in the Faroe Island marine ecosystem as changing functions of both fish mortality (commercial catch rates) and clim...
