In deeper waters6/7/2023 ![]() During the stable stratified period, increases in the strength or duration of thermal stratification isolate the cool, deeper waters by reducing vertical mixing 1, 2, with profound implications for nutrient and oxygen availability 3, 4, primary productivity 5, 6, 7, and fisheries production and habitat 5, 8, 9. The consequences of climate and environmental changes on lake thermal structure affect the ecological function of lakes, including key processes like nutrient cycling and depletion of deepwater dissolved oxygen. These findings suggest that external drivers beyond our tested lake characteristics are important in explaining long-term trends in thermal structure, such as local to regional climate patterns or additional external anthropogenic influences. The variability in deepwater temperature trends was not explained by trends in either surface water temperatures or thermal stability within lakes, and only 8.4% was explained by lake thermal region or local lake characteristics in a random forest analysis. In contrast, however, deepwater temperature trends showed little change on average (+ 0.06 ☌ decade −1), but had high variability across lakes, with trends in individual lakes ranging from − 0.68 ☌ decade −1 to + 0.65 ☌ decade −1. We found significant increases in surface water temperatures across lakes at an average rate of + 0.37 ☌ decade −1, comparable to changes reported previously for other lakes, and similarly consistent trends of increasing water column stability (+ 0.08 kg m −3 decade −1). We have compiled the most comprehensive data set to date of long-term (1970–2009) summertime vertical temperature profiles in lakes across the world to examine trends and drivers of whole-lake vertical thermal structure. Globally, lake surface water temperatures have warmed rapidly relative to air temperatures, but changes in deepwater temperatures and vertical thermal structure are still largely unknown. Scientific Reports volume 10, Article number: 20514 ( 2020) Tal must escape if he hopes to save his family and the kingdom.Deeper waters are changing less consistently than surface waters in a global analysis of 102 lakes But before they can pursue anything further, Tal is kidnapped by pirates and held ransom in a plot to reveal his rumored powers and instigate a war. ![]() That is, until Tal runs into Athlen days later on dry land, very much alive, and as charming-and secretive-as ever. So when Athlen leaps overboard and disappears, Tal feels responsible and heartbroken, knowing Athlen could not have survived in the open ocean. Tasked with watching over the prisoner, Tal is surprised to feel an intense connection with the roguish Athlen. His first taste of adventure comes just two days into the journey, when their crew discovers a mysterious prisoner on a burning derelict vessel. After spending most of his life cloistered behind palace walls as he learns to keep his forbidden magic secret, he can finally see his family’s kingdom for the first time. Prince Tal has long awaited his coming-of-age tour. “A frothy confection of sea-foam, young love, and derring-do.” -NPRįrom the New York Times bestselling author of So This Is Ever After, a young prince must rely on a mysterious stranger to save him when he is kidnapped during his coming-of-age tour in this swoony adventure that is The Gentleman’s Guide to Vice and Virtue meets Pirates of the Caribbean.
