Evolution and Revolution in Measuring Ocean Optical Properties
Evolution and Revolution Ocean Optical
2015/8/4
Measuring and interpreting the optical properties of ocean waters has been, and continues to be a challenging endeavor in oceanography. Just as the measurements of temperature~ salinity and density (T...
Advances in ocean optical modeling and sensor design, coupled with the development of autonomous sampling platforms, have provided the oceanographic community with unprecedented opportunities to measu...
Optics of the Sea Floor
Optics Sea Floor
2015/8/4
The Bahamas. You drop off the side of a small boat in clear tropical waters and swim over a lightly current-rippled bright sand bottom, spotted with brown patches of microalgae. You pass over a dark p...
Underwater Optical Imaging:Status and Prospects
Underwater Optical Imaging Status and Prospects
2015/8/4
As any backyard stargazer knows, one simply has to look up at the sky on a cloudless night to see light whose origin was quite a long time ago. Here, due to the fact that the mean scattering and absor...
Settling Particles in Aquatic Environments:Low Reynolds Numbers
Settling Particles Aquatic Environments Low Reynolds Numbers
2015/7/23
The purpose of this activity is to familiarize students with how a particle's size, shape and orientation affects its settling at low Reynolds numbers. This activity can also be used to teach statisti...
Physical processes in the world's oceans span an enormous range of spatio-temporal scales, from ocean circulation at the global scale down to dissipation and mixing at the centimeter scale. It is impo...
Quantifying Uncertainties in Ocean Predictions
Ocean Predictions Quantifying Uncertainties
2015/7/23
A multitude of physical and biological processes occur in the ocean over a wide range of temporal and spatial scales. Many of these processes are nonlinear and highly variable, and involve interaction...
Computational simulation is now an essential methodology of science, along with theory and observation. The ability of scientists to understand and predict planetary climate variability largely depend...
Coupled Biological and Physical Models:Present Capabilities and Necessary Developments for Future Studies of Population Connectivity
Coupled Biological Physical Models Present Capabilities Necessary Developments Future Studies Population Connectivity
2015/7/22
The combination of wide-ranging spatial and temporal scales associated with the oceanic environment, together with processes intrinsic to the biology of marine organisms, makes the quantitative study ...
There is probably nothing more foundational to understanding the ocean than the study of salinity. New discoveries regarding its magnitude and variability continue to feed our knowledge of the nature ...
Forecasting the Ocean's Optical Environment Using the BioCast System
Ocean's Optical Environment BioCast System
2015/7/20
The Bio-Optical Forecasting (BioCast) system is a model that provides the US Navy with short-term forecasts of the ocean's optical environment. The forecasts are required to support a broad spectrum o...
The Fate of Fisheries Oceanography: Introduction to the Special Issue
Special Issue Fisheries Oceanography
2015/7/20
What is Fisheries Oceanography? Fisheries oceanography can be broadly defined as study of the interaction between marine fish and their environments across multiple life-history stages. Traditional fi...
A Framework for a Marine Biodiversity Observing Network Within Changing Continental Shelf Seascapes
Changing Continental Shelf Seascapes Biodiversity Observing
2015/7/17
Continental shelves and the waters overlying them support numerous industries as diverse as tourism and recreation, energy extraction, fisheries, transportation, and applications of marine bio-molecul...
Hovercraft as a Mobile Science Platform Over Sea Ice in the Arctic Ocean
Arctic Ocean Science Platform Over Sea Ice
2015/7/17
Physical sampling of sea ice, the water mass, and subbottom geology in the Arctic Ocean is carried out from icebreakers or temporary ice camps deployed and supported by aircraft. Here, we consider an ...
The importance of Dissimilatory Nitrate reduction to ammonium (DNra) in the Nitrogen cycle of coastal ecosystems
Dissimilatory Nitrate Nitrogen cycle
2015/7/16
Until recently, it was believed that biological assimilation and gaseous nitrogen (N) loss through denitrification were the two major fates of nitrate entering or produced within most coastal ecosyste...
