Until recently, hydrothermal vents were not considered to be an important source to the marine dissolved Fe (dFe) inventory because hydrothermal Fe was believed to precipitate quantitatively near the vent site. Based on recent abyssal dFe enrichments near hydrothermal vents, however, the leaky vent hypothesis [Toner BM, et al. (2012) Oceanography 25(1):209-212] argues that some hydrothermal Fe ...

Animals that display plasticity in behavioral, ecological, and morphological traits are better poised to cope with environmental disturbances. Here, we examined individual intraspecific variation the morphometrics, movement patterns, dive behavior of an enigmatic apex predator, leopard seal ( Hydrurga leptonyx ). Satellite/GPS tags time-depth recorders were deployed on 22 seals off Western Anta...

This is a cryostat for the ProtoDUNE II neutrino detector test bed located at CERN nuclear research center on France-Switzerland border. It precursor to DUNE (Deep Underground Neutrino Experiment) detector. prototype and now under construction in United States benefit from experience gained design, construction, operation of facilities such as Large Hadron Collider (also CERN). The generator Fe...

Tidal currents flowing over benthic relief (e.g., banks, shelf break) can produce large internal waves. These waves propagate away from their origin and are capable of crossing the continental seas. Studies shoreward transport larval invertebrates fish by these unintentionally tested whether they capture, concentrate floating plastic. Plastic surface drifters deployed in front sets wave converg...

Most documents can be said to be related to some form of geographic context and, recently, geographic information retrieval has captured the attention of researchers from fields related to text mining and data retrieval, envisioning the support for tasks such as map-based document indexing, retrieval and visualization. In this paper, I empirically evaluate automated techniques, based on a hiera...

BACKGROUND Since physical activity levels in older adolescents have the potential to be increased by stimulating active transportation to school (ATS), the most important correlates of ATS should be determined before developing interventions, especially in those adolescents for whom the distance to school is feasible for active commuting. The main aims of this study were to determine criterion ...

On 8 January 2022, a Moment Magnitude (Mw) 6.7 earthquake occurred in Menyuan, China. The epicenter was located the western segment of Lenglongling fault Qilian-Haiyuan zone. In this area, Mw 5.9 Menyuan on 26 August 1986 and 21 2016 successively occurred. seismogenic structures earthquakes are Northern fault, which is few kilometers away from fault. After 2022 earthquake, we collected GF-7 Sen...

The area accessible from a spaceborne imaging radar, e.g. a synthetic aperture radar (SAR), generally increases with the elevation of the satellite while the map coverage rate is a more complicated function of platform velocity and beam agility. The coverage of a low Earth orbit (LEO) satellite is basically given by the ground velocity times the relatively narrow swath width. The instantaneousl...
