The Earth's biggest magmatic events are believed to originate from massive melting when hot mantle plumes rising from the lowermost mantle reach the base of the lithosphere. Classical models predict large plume heads that cause kilometre-scale surface uplift, and narrow (100 km radius) plume tails that remain in the mantle after the plume head spreads below the lithosphere. However, in many cas...

Technological improvements over the past decade have led to the widespread use of autonomous surface and underwater vehicles for data collection in marine environmental sensing and modeling in coastal environments. However, these vehicles and their sensors still have limitations, especially when tasked with observing highly dynamic or transient processes. We investigate the application of a sma...

Observations of magnetic reconnection between colliding plumes of magnetized laser-produced plasma are presented. Two counterpropagating plasma flows are created by irradiating oppositely placed plastic (CH) targets with 1.8-kJ, 2-ns laser beams on the Omega EP Laser System. The interaction region between the plumes is prefilled with a low-density background plasma and magnetized by an external...
