lutants travel, they move in stages through a repeated process of volatilization and deposition. To learn more about this "grasshopper effect," Jurado and Dachs focus on a class of persistent organic pollutants called polychlorinated biphenyls (PCB). Through studies of the grasshopper effect's seasonal variability and long-range atmospheric transport potentials, the authors find that the number of hops taken by a chemical over the oceans is driven by seasonal biogeochemical processes occurring in the water column. For example, the transport of PCBs to the remote Arctic is maximized during seasons of low primary productivity. Such studies have important implications for understanding the distribution and fractionation processes of persistent organic pollutants on a global scale.

Title: Seasonality in the "grasshopping" and atmospheric residence times of persistent organic pollutants over the oceans

5. Antarctica ice-sheet loss modeled

The West Antarctic Ice Sheet has been rapidly losing mass to the oceans over recent decades. The most significant losses have occurred across the Amundsen Sea coastline, where dynamical changes in outlet glaciers have led to increased discharge. The synchronous response of several independent glaciers is generally considered an indicator that the changes are being forced by warming ocean waters. Scientists have documented deep flooding over the Amundsen Sea's continental shelf by almost unmodified Circumpolar Deep Water (CDW); though cold, this deep water is several degrees above freezing and drives rapid melting of the floating terminus of the Pine Island Glacier.
