We present the results of a study of optical scattering and backscattering of particulates for three coastal sites that represent a wide range of optical properties that are found in U.S. near-shore waters. The 6000 scattering and backscattering spectra collected for this study can be well approximated by a power-law...
Hydrological optics has a rich history, playing a significant role in physical, chemical, and biological oceanography. The success over the last 30 years has provided oceanographers with a non-invasive means to study regional and global scale physical, chemical, and biological processes (Figure 1). The ability to map the color of...
Hyperion is a hyperspectral sensor on board NASA’s EO-1 satellite with a spatial
resolution of approximately 30 m and a swath width of about 7 km. It was originally designed
for land applications, but its unique spectral configuration (430 nm – 2400 nm with a ~10 nm
spectral resolution) and...
The physical, biological, chemical, and optical
processes of the ocean operate on a wide
variety of spatial and temporal scales, from
seconds to decades and from micrometers to
thousands of kilometers (Dickey et al., this
issue; Dickey, 1991). These processes drive
the accumulation and loss of living and nonliving
mass...
In optically shallow waters, i.e., when the bottom is visible through the water,
a tantalizing variety and level of detail about bottom characteristics are
apparent in aerial imagery (Figure 1a). Some information is relatively easy to
extract from true color, 3-band imagery (e.g., the presence and extent of submerged
vegetation),...
Global ocean phytoplankton biomass (C-phyto) and total particulate organic carbon (POC) stocks have largely been characterized from space using passive ocean color measurements. A space-based light detection and ranging (lidar) system can provide valuable complementary observations for C-phyto and POC assessments, with benefits including day-night sampling, observations through absorbing aerosols...
