TL;DR: In this article, the authors investigated the cause of tropical Indian Ocean (TIO) sea surface temperature (SST) warming, increased tropical tropospheric temperature, an anomalous anticyclone over the subtropical northwest Pacific, and increased mei-yu-baiu rainfall over East Asia.

TL;DR: Results from 22 years of plankton tows in the North Atlantic showed the pattern of plastics accumulation was indeed as predicted by theories of ocean circulation, but, despite the steady increase in plastic production and disposal, the concentration of plastic debris had not increased and no trend in plastic concentration was observed in the region of highest accumulation.

TL;DR: The geography and structure of the collection regions are characterized and factors that determine their dynamics are discussed and a new scale R(c)=(4k/|D|)(½) is introduced to characterize tracer distribution under competing effects of horizontal divergence D and diffusion k.

TL;DR: A transect through the South Pacific subtropical gyre carried out in March-April 2011 bisected a predicted accumulation zone associated with the convergence of surface currents, driven by local winds, showing an increase in surface abundance of plastic pollution as the authors neared the center and decrease as they moved away, verifying the presence of a garbage patch.

TL;DR: It is demonstrated that the extreme warming off the west coast of Australia in February–March 2011 was mostly driven by an unseasonable surge of the poleward-flowing Leeuwin Current in austral summer, which transported anomalously warm water southward along the coast.
