Living with the Georgia Shore
The wide sandy beaches, quiet maritime forests, and vast Spartina marshes of the natural Georgia coast create a most spectacular, albeit gentle, Southern beauty. Casual visitors and longtime residents alike have been charmed by this special place. Living with the Georgia Shore provides an essential reference and guide for residents, visitors, developers, planners, and all who are concerned with the conditions and future of Georgia's coastal zone. Recounting the human and natural history of the islands, the authors look in particular at the phenomenon of coastal erosion and the implications of various responses to this process. In Georgia, as elsewhere in the United States, the future of the ...
How to Read a Florida Gulf Coast Beach
Come explore the geology of Florida's Gulf Coast beaches, from a bird's-eye view down to a crab's-eye view. You'll journey from Panhandle sugar-sand beaches to southwestern shell beaches, taking a fresh look at the ever-changing landscape. With Tonya Clayton as your guide, you'll learn how to recognize the stories and read the clues of these dynamic shores, reshaped daily by winds, waves, and sometimes bulldozers or dump trucks. This dynamic tour begins with a broad description of Florida's Gulf Coast, roaming from popular Perdido Key in the northwest to remote Cape Sable in the south. You'll first fly over large-scale coastal features such as the barrier islands, learning to spot signs of t...
Designing Nanostructures at the Interface between Biomedical and Physical Systems
Last November, the National Academies Keck Futures Initiative held the Designing Nanostructures at the Interface Between Biomedical and Physical Systems conference at which researchers from science, engineering and medicine discussed recent developments in nanotechnology, directions for future research, and possible biomedical applications. The centerpiece of the conference was breakout sessions in which ten focus groups of researchers from different fields spent eight hours developing research plans to solve various problems in the field of nanotechnology. Among the challenges were: Building a nanosystem that can isolate, sequence and identify RNA or DNA Developing a system to detect diseas...
Restoring Lands - Coordinating Science, Politics and Action
Environmental issues, vast and varied in their details, unfold at the confluence of people and place. They present complexities in their biophysical details, their scope and scale, and the dynamic character of human action and natural systems. Addressing environmental issues often invokes tensions among battling interests and competing priorities. Air and water pollution, the effects of climate change, ecosystem transformations—these and other environmental issues involve scientific, social, economic, and institutional challenges. This book analyzes why tackling many of these problems is so difficult and why sustainability involves more than adoption of greener, cleaner technologies. Susta...
Design and Evaluation of a Directional Antenna for Ocean Buoys
A system concept has been developed by Viasat, Inc. and Woods Hole Oceanographic Institution for improving the data telemetry bandwidth available on ocean buoys. This concept utilizes existing communications satellites as data relay stations and mechanically steered antenna arrays to achieve increased data rates and improved power efficiency needed for ocean applications. This report describes an initial feasibility and design study to determine if a mechanically steered antenna array can meet the requirements of open ocean buoy applications. To meet the system requirements, an 18-element microstrip antenna (9-element transmit, 9-element receive) was designed and fabricated under subcontract...
Living with Florida's Atlantic Beaches
A call to live with the coast, as opposed to living at the coast; unless Florida coastal communities conserve beaches and mitigate storm impacts, the future of the beach-based economy is in question.
Collaborations of Consequence
This publication represents the culmination of the National Academies Keck Futures Initiative (NAKFI), a program of the National Academy of Sciences, the National Academy of Engineering, and the National Academy of Medicine supported by a 15-year, $40 million grant from the W. M. Keck Foundation to advance the future of science through interdisciplinary research. From 2003 to 2017, more than 2,000 researchers and other professionals across disciplines and sectors attended an annual "think-tank" style conference to contemplate real-world challenges. Seed grants awarded to conference participants enabled further pursuit of bold, new research and ideas generated at the conference.
Living on the Edge of the Gulf
A new look at the West Florida and Alabama Gulf shoreline, in the context of burgeoning development and revised coastal regulations.
Seasonal Carbon Cycling in the Sargasso Sea Near Bermuda
Each year, the concentration of dissolved inorganic carbon (DIC) in the mixed layer at Station S in the Sargasso Sea decreases from winter to summer by about 30 umol/kg. The authors of this study demonstrate that by simultaneously observing changes in the stable isotopic ration of DIC, it is possible to quantify the contribution of physical and biological processes to this summer-fall drawdown. They find that biology is the dominant contrbutor to the drawdown, but that physical processes also play an important role.
