Impacts of CO2 Perturbation on the Ecology and Biogeochemistry of Plankton Communities During a Simulated Upwelling Event: A Mesocosm Experiment in Oligotrophic Subtropical Waters
This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact.
Ocean Artificial Upwelling – Ecological Responses and Biogeochemical Impacts
Feeding a growing human population and achieving net-zero CO2 emissions by 2050 are the great challenges of the 21st century. Whilst terrestrial resources are already utilized intensively by competing societal sectors, the vast ocean ecosystems still hold untapped potential. The productivity of the ocean is, however, limited by the transport of nutrient-rich deep waters to the sun-lit surface layer. In large parts of the global ocean, this transport is blocked by a temperature-induced density gradient, with warm light waters residing on top of heavier cold waters. The upward transport of nutrient-rich deep waters through artificial upwelling can break this blockade and enhance primary production. However, little is presently known about the ecological responses to forced upwelling in oligotrophic waters, their impacts on biogeochemical cycling and possible feedbacks to the climate system. In view of its potential contribution to securing marine food production and mitigating climate change, a comprehensive assessment of the feasibility, effectiveness, and associated risks of artificial upwelling is of particular scientific and societal interest.
The Sounds of Life
An amazing journey into the hidden realm of nature’s sounds The natural world teems with remarkable conversations, many beyond human hearing range. Scientists are using groundbreaking digital technologies to uncover these astonishing sounds, revealing vibrant communication among our fellow creatures across the Tree of Life. At once meditative and scientific, The Sounds of Life shares fascinating and surprising stories of nonhuman sound, interweaving insights from technological innovation and traditional knowledge. We meet scientists using sound to protect and regenerate endangered species from the Great Barrier Reef to the Arctic and the Amazon. We discover the shocking impacts of noise po...
The Warming Papers
Chosen for the 2011 ASLI Choice - Honorable Mention (History Category) for a compendium of the key scientific papers that undergird the global warming forecast. Global warming is arguably the defining scientific issue of modern times, but it is not widely appreciated that the foundations of our understanding were laid almost two centuries ago with the postulation of a greenhouse effect by Fourier in 1827. The sensitivity of climate to changes in atmospheric CO2 was first estimated about one century ago, and the rise in atmospheric CO2 concentration was discovered half a century ago. The fundamentals of the science underlying the forecast for human-induced climate change were being published ...
Global Warming and the Climate Crisis
This textbook introduces readers to basic scientific principles of climate change. Based on extensive empirical evidence, it explains weather events that indicate climate change’s evolution and presents important topics connected to climate change, such as political controversies, climate policy, as well as Native American perspectives. Finally, it presents attempted solutions, including policy recommendations and technological proposals for necessary changes in our world. Providing a well-written and easy-to-follow overview of knowledge of science-based geophysical facts, including thermodynamics, the book puts a strong emphasis on why expeditious action on global warming is urgent. The b...
Our Dying Planet
Weaving into the narrative his own firsthand field experiences around the world, the author, an ecologist brings ecology alive while giving a solid understanding of the science at work behind today's pressing environmental issues. He delves into topics including deforestation, biodiversity loss, over fishing, population growth, use of fossil fuel and climate change while discussing the real consequences of out growing ecological footprint. Coral reefs are on track to become the first ecosystem actually eliminated from the planet. So says the author in this crash course on the state of the planet. He draws from his own extensive work on coral reefs, and from recent research by other ecologists, to explore the many ways we are changing the Earth and to explain why it matters. Most important, this book emphasizes that a gloom-and-doom scenario is not inevitable, and as the author explores alternative paths, he considers the ways in which science can help us realize a better future.
Seasick
We have long lorded over the ocean. But only recently have we become aware of the myriad life-forms beneath its waves. We now know that this delicate ecosystem is our life-support system; it regulates the earth’s temperatures and climate and comprises 99 percent of living space on earth. So when we change the chemistry of the whole ocean system, as we are now, life as we know it is threatened. In Seasick, veteran science journalist Alanna Mitchell dives beneath the surface of the world’s oceans to give readers a sense of how this watery realm can be managed and preserved, and with it life on earth. Each chapter features a different group of researchers who introduce readers to the import...
