However, few studies have been found to focus on survey of underwater gliders (UGs) motion performance inside mesoscale eddies. The dynamic model UG considering eddy density is established predict its eddy. Ignoring effect vertical velocity UG, simulation results experimental data are compa...

Population density and home range are the two major ecological characteristics pertaining to the ecosystem-level energy use by the species. Home range usually grows more rapidly with body size than does individual metabolic rate. Neither this phenomenon nor the observed absence of isometry between inverse home range and population density (the latter often scaling as the reciprocal of metabolic...

Eight years of passive acoustic data (2007–2014) from the Beaufort Sea were used to estimate mean cue rate (calling rate) individual bowhead whales (Balaena mysticetus) during their fall migration along North Slope Alaska. Calls detected on directional recorders (DASARs) triangulated provide estimates locations at times call production, which then translated into densities (calls/h/km2). Variou...
