Evolution of a Man-Made Plume in Coastal Waters
The ability to understand the biogeophysical parameters that create ocean color in coastal waters is fundamental to the ability to exploit remote sensing for coastal applications. This article describes an experiment in which a controlled quantity of a single inorganic material with known absorption and scattering properties was released into a coastal environment. The plume experiment was conducted in conjunction with a Pacific Northwest National Laboratory (PNNL) field collection campaign in and around Sequim Bay on the Strait of Juan de Fuca in Washington State. The objective of the field campaign was to identify and characterize features in the near shore environment from the standpoint of quantifying environmental parameters to improve operational planning in littoral regions. The aerial component of the mission involved imagery acquisitions from the NRL's PHILLS hyperspectral sensor, and two commercial IR cameras. Coincident satellite data was obtained from commercial sources. Ground truth activities included atmospheric profiles, ground, surface water, and in-water spectral measurements, panels for radiometric calibration, water column water optics, water samples and profiles from support vessels, in-situ tide and weather measurements, and beach and intertidal transects and surveys (via scientific dive teams). This field collection campaign provided a unique opportunity for a multisensor data collection effort in littoral regions, to identify and characterize features from multiple platforms (satellite, aerial, water surface and subsurface) and sensors. Data from this mission is being used as input to both radiative transfer and ocean transport models, for characterizing the water column and the near-shore, and quantitatively estimating circulation and transport in coastal environments.
