SURFACE SNOW DENSITY OF EAST ANTARCTICA DERIVED FROM IN-SITU OBSERVATIONS
Surface snow density Matrix completion Empirical Orthogonal Function Kriging
2018/5/15
Models based on physical principles or semi-empirical parameterizations have used to compute the firn density, which is essential for the study of surface processes in the Antarctic ice sheet. However...
Cofortification of ferric pyrophosphate and citric acid/trisodium citrate into extruded rice grains doubles iron bioavailability through in situ generation of soluble ferric pyrophosphate citrate complexes
iron bioavailability iron fortification extruded rice ferric pyrophosphate trisodium citrate iron deficiency
2018/11/29
Background: Iron fortification of rice is a promising strategy for improving iron nutrition. However, it is technically challenging because rice is consumed as intact grains, and ferric pyrophosphate ...
Optical measurements of atmospheric particles from airborne platforms:in situ and remote sensing instruments for balloons and aircrafts
remote sensing LIDAR backscattersonde aerosol
2015/9/7
Multiwavelength laser backscattersondes (MAS) have been widely used from a variety of airborne platforms for in situ measurements of optical properties of clouds and atmospheric particulate as well as...

One of the challenges we face as oceanographers is the wide range of spatial and temporal scales over which we must measure the physical, biological, and chemical properties and processes in the ocean...
Value Added Benefits of High Definition Surveying (Laser Scanning) in Contrast to In-Situ Surveying for Erosion of Hydrological Waterways
Laser Scanning waterway surveying
2015/8/14
The purpose of this paper is to depict and illustrate the benefits of High DefinitionSurveying (HDS) also known as 3-dimensional laser scanning, in contrast to traditional surveying methods, such as R...
New Sensor Technology for In Situ Measurements of Ocean Chemistry
New Sensor Technology Situ Measurements Ocean Chemistry
2015/8/14
Chemical processes in the ocean and at its interfaces with the atmosphere and the seafloor play a major role in regulating global biogeochemical cycles. Predicting the impact of human disturbances on ...
Ocean-observing systems are changing the way ocean science is accomplished. No longer is ocean science limited to observations made by ships, whose scheduling and expense often constrain research to s...
