Remote-sensing reflectance is easier to interpret for the open ocean than for coastal regions because the optical signals are highly coupled to the phytoplankton (e.g., chlorophyll) concentrations. For estuarine or coastal waters, variable terrigenous colored dissolved organic matter (CDOM), suspended sediments, and bottom reflectance, all factors that do not covary...
The Moderate Resolution Imaging Spectroradiometer (MODIS) will add a significant new capability for investigating the 70% of the Earth's surface that is covered by oceans, in addition to contributing to the continuation of a decadal scale time series necessary for climate change assessment in the oceans. Sensor capabilities of particular...
The propagation of downwelling irradiance at wavelength l from surface to a depth (z) in the ocean is governed by the diffuse attenuation coefficient, K𝒹(λ). There are two standard methods for the derivation of K𝒹(λ) in remote sensing, which both are based on empirical relationships involving the blue-to-green ratio of...
Ocean color remote-sensing systems require highly accurate calibration (<0.5%) for accurate retrieval of water properties. This accuracy is typically achieved by vicarious calibration which is done by comparing the atmospherically corrected remote-sensing data to accurate estimates of the water-leaving radiance. Here we present a new method for vicarious calibration of...
Euphotic zone depth, z[subscript]1%, reflects the depth where photosynthetic available radiation
(PAR) is 1% of its surface value. The value of z[subscript]1% is a measure of water clarity, which is
an important parameter regarding ecosystems. Based on the Case-1 water assumption,
z[subscript]1% can be estimated empirically from the remotely derived...
The distribution of particles in the Eastern Pacific Ocean was
investigated from 2 January to 14 February, l969, on the YALOC-69
cruise of Oregon State University. The size distributions were well
fitted by the two-parameter Weibull distribution function, with a
predominant number of them nearly exponential in distributional
shape. Although...
