We evaluate the theoretical performance of a point-source integrating-cavity absorption meter (PSICAM) with Monte Carlo simulations and a sensitivity analysis. We quantify the scattering errors, verifying that they are negligible for most ocean optics applications. Although the PSICAM detector response is highly sensitive to the value of the wall reflectivity,...
Remotely sensed sea surface temperature (SST) and a model originally developed for Cap Blanc, northwest Africa [Dugdale et al., 1989], are used to estimate new production (i.e., nitrate uptake, in the sense of Dugdale and Goering [1967]) for the persistent coastal upwelling feature at Point Conception, California. Parameters required to...
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...
Macronutrients persist in the surface layer of the equatorial Pacific Ocean because the production of phytoplankton is limited; the nature of this limitation has yet to be resolved. Measurements of photosynthesis as a function of irradiance (P-I) provide information on the control of primary productivity, a question of great biogeochemical...
As a demonstrator for technologies for the next generation of ocean color sensors,
the Hyperspectral Imager for the Coastal Ocean (HICO) provides enhanced spatial and
spectral resolution that is required to understand optically complex aquatic environments. In
this study we apply HICO, along with satellite remote sensing and in situ...

Current ocean color sensors, for example SeaWiFS and MODIS, are well suited for sampling the open ocean. However,
coastal environments are spatially and optically more complex and require more frequent sampling and higher spatial
resolution sensors with additional spectral channels. We have conducted experiments with data from Hyperion and
airborne...
Existing atmospheric correction algorithms for multichannel remote sensing of ocean color from space were designed for retrieving water-leaving radiances in the visible over clear deep ocean areas and cannot easily be modified for retrievals over turbid coastal waters. We have developed an atmospheric correction algorithm for hyperspectral remote sensing of...
