Magnetic reconnection has long been thought to play an important role in turbulent plasmas – with the nonlinear dynamics of systems being well known self-consistently generate intense current structures and associated magnetic shears that can be sites where so-called turbulence-driven occur. However, complex three-dimensional topologies small-scale nature these events have traditionally made it challenging assess from either a numerical or observational perspective. Recent high-resolution observations NASA’s Magnetospheric Multiscale (MMS) mission provided unprecedented new opportunity systematically examine region shock-driven turbulence within Earth’s magnetosheath. These insight into plasmas, revealing under right conditions electron-only reconnection, which ion jets are not accelerated by newly reconnected fields, In this talk, we explore how observationally constrain contribution makes energy dissipation rate turbulence. We then directly compare estimates observed MMS cascade for specific intervals magnetosheath observe within. The potential implications traditional ion-coupled versus budget overall discussed detail.
