DOI: 10.1002/2017gl073368
Abstract: Electrical and electromagnetic methods are extensively used to map electrically conductive tracers within hydrogeologic systems. Often, the tracers used consist of dissolved salt in water, leading to a denser mixture than the ambient formation water.… read more here.

DOI: 10.1002/lno.11389
Abstract: The meroplanktonic larvae of many invertebrate and vertebrate species rely on physical transport to move them across the shelf to their adult habitats. One potential mechanism for cross‐shore larval transport is Stokes drift in internal… read more here.

DOI: 10.1016/j.marchem.2017.06.011
Abstract: Abstract Radium (Ra) isotopes are enriched in hydrothermal fluids, have a wide range of half-lives and are minimally impacted by scavenging removal processes; therefore, they have the ability to provide key information on the fate… read more here.

DOI: 10.1016/j.oceaneng.2020.107512
Abstract: Abstract The net buoyancy, driving force of underwater gliders, decreases gradually when the gliders dive or climb in the seawater, which increases the energy consumption and reduces the gliding range. The neutrally buoyant hull is… read more here.

DOI: 10.1103/physrevfluids.8.054501
Abstract: Inertial particles in stably stratified flows play a fundamental role in geophysics, from the dynamics of nutrients in the ocean to the dispersion of pollutants in the atmosphere. We consider the Maxey-Riley equation for small… read more here.
