Mercury (Hg) concentrations and Hg isotopic composition were investigated in three sediment cores in Lake Michigan (LM).

Overall, this study suggests that sedimentary Hg isotopes maybe a useful tracer in understanding Hg sources and history of Hg contamination in large lakes.

Upon entering aquatic ecosystems, Hg may undergo complex reactions and transformations including oxidation, reduction, evasion to the atmosphere as gaseous Hg(0), binding to organic matter in the water column, and adsorbing to particles and depositing to sediments ().

An evil curse sends seven of Storybrooke's best into the dreamscape and it'll take all their combined wits to make it out. Pandora arrives in Storybrooke, looking for her magical box and sending every person in town back to a troubling time in their life. And can Emma and Killian find each other, and save the people of Storybrooke? What if Hermione was a Pureblood, sorted into Slytherin? No one is who they appear to be, and loyalties are rebuilt and tested as everyone tries to navigate their new path.

-If her friends were Draco Malfoy & Pansy Parkinson and her enemies were Harry Potter & Ron Weasley? When the machinations of an evil man threaten them all, can Emma and Killian overcome their differences to defeat him?

Historical trends of Hg influxes suggest increased Hg deposition began in the 1890s in Green Bay and in the early 1800’s in offshore LM.

Recently deposited sediment reflecting more anthropogenic influence shows similar δHg values (-0.02 to 0.27‰) was observed from inner Green Bay to the offshore of LM, which may indicate increased input of atmospheric Hg and decreased watershed inputs along this transect.

It’s the show that reveals whether it’s possible to fall in love with someone you’ve spoken to at length, you’ve touched, perhaps even tasted… And although they’re not able to see a thing, viewers will, thanks to infrared cameras, be able to see everything that’s taking place!

On the last day, each of the participants will choose a partner based on their previous mutual encounters in the dark.

When a banshee targets Emma's family, it means someone is facing a certain death.
