Abstract The location of mixing due to internal tides is important for both the ocean circulation as well local biogeochemical processes. Numerous observations and modeling studies have shown that submarine canyons may be regions enhanced tide‐driven mixing, but there has not yet been a systematic study all resolved in bathymetric datasets. Here, we parameterize dissipation from suite simulatio...

Dissolved iron (dFe) and copper (dCu), the concentration conditional stability constants of organic binding ligands (LFe, LCu, log KcondFe3+L KcondCu2+L) were studied in surface coastal waters Macaronesia region (Cape Verde, Canary Islands, Madeira) using competitive ligand exchange-adsorptive cathodic stripping voltammetry (CLE-ACSV). Two oceanic stations also studied: Cape Verde Ocean Observa...

Earthquakes cause rock fracturing, opening new flow pathways which can result in the mixing of previously isolated geofluids with differing geochemistries. Here, we present first evidence that seismic events significantly reduce groundwater pH without requirement for fluid mixing, solely through process dynamic fracturing. At Grimsel Test Site, Switzerland, observe repeated, short-lived drops 1...

The flexible superhydrophobic thermoplastic polyurethane(TPU) porous material was prepared by heat-induced phase separation method with two cooling steps. influence of the preparation process on microstructure discussed in depth. microstructure, hydrophobicity and specific surface area TPU materials were analyzed detail. wettability, selectivity, saturated adsorption capacity rate, mechanical p...

Models of neutrino masses are discussed capable of explaining in a natural way the maximal mixing between ν µ and ν τ observed by the Super-Kamiokande collaboration. For three generations of leptons two classes of such models are found implying: a) ∆m 23 2 ≪ ∆m 12 2 ≈ ∆m 13 2 and a small mixing between ν e and the other two neutrinos, b) ∆m 12 2 ≪ ∆m 13 2 ≈ ∆m 23 2 and a nearly maximal mixing f...
