 | This effort delivered the ability to produce bathymetry, bottom typing, and water column optical property estimates from multispectral and hyperspectral imagery products in Very Shallow Waters (VSW). The VSW is a very different remote sensing environment relative to Deep Water (DW) environments, and requires special algorithms to retrieve these environmental products. The algorithms and software transitioned in the deliverables are based on an optimized spectral matching technique. This technique starts ... |

| The focus of this effort is to create a managed library appliance that supports the Navy METOC personal in their ability to search for in-house hyperspectral and multispectral imagery products, and provide algorithms that create bathymetry estimates from those imagery products on-demand. This one-year effort seeks to deliver an image library system that handles terabytes of imagery products with a simple and easy to use index, search, discovery, and delivery ... |

| This project seeks to develop the technology to fuse high spatial resolution Multi Spectral Imagery (MS I) with lower spatial resolution, but higher spectral resolution, HyperSpectral Imagery (HSI) to provided enhanced target detection and battlespace characterization. It seeks to push beyond traditional PAN sharpening techniques to develop applications that will increase the accuracy and fidelity of the sharpened spectral imagery. |

|
| The LUT approach to inverting ocean color spectral remote- sensing data seeks to use the greater number of degrees of freedom available in the hyperspectral data to retrieve (1) bathymetry, (2) water column lOPs, and (3) bottom identification in optically-shallow waters. We have discovered several significant findings in developing this approach. First is that the quality of the input measured spectra is critical to the success of the technique. Thus, ... |

|
| The optical impacts of a scattering benthic boundary layer are fairly obvious to in situ and remote sensing techniques that measure ocean color. These scattering layers cause an increase in light reflectance from positions above the benthos, a reduction in the penetrating photons to the bottom, and a decrease in photons scattered from the bottom back toward the surface. The net result is that these layers reduce the ability of ... |

| Atmospheric correction of coastal hyperspectral remotely sensed data is a difficult problem. The subtle yet variable signals found in these areas do not lend themselves to traditional techniques of selecting atmospheric correction parameters. The procedures investigated not only address how to select these parameters given ground truth data, but also suggest ways in which atmospheric correction can be done completely remotely. In addition to the development of operational atmospheric correction ... |

|
| This effort produced a fully coupled physical, chemical, biological, and optical numerical model, which at its foundation is the community physical model ROMS 2.2. This physical model enjoys wide spread support in the open source ocean modeling community, and continues to receive development funding from the Navy and the National Science Foundation. The chemical and biological model includes the ability to simulate multiple groups of phytoplankton, multiple limiting nutrients, spectral ... |

|
| The work in this effort centered on HyperSpectral Imaging (HSI) data collection and HSI sensor calibration. The data collection occurred at high altitudes (^30,000 ft.) off the coast of Mobile, AL and at lower altitudes (^10,000 ft) in the Florida Keys. These data have been used in multiple presentations and publications in the development of robust HSI data collection and processing techniques, which are suitable for the characterization of the ... |

| This work focuses on the development of ecological and optical interaction equations embedded in a 2D hindcast model of the shallow water optical properties on the West Florida Shelf (WFS) during late summer/fall of 1998. This 2D simulation of the WFS includes one case with a Loop Current intrusion above the 40-m isobath and one with the Loop Current intrusion, in addition to a periodic terrestrial nutrient supply below the ... |

| The Ocean Portable Hyperspectral Imager for Low-Light Spectroscopy (Ocean PHILLS) is a hyperspectral imager specifically designed for imaging the coastal ocean. It uses a thinned, backside illuminated CCD for high sensitivity and an all-reflective spectrograph with a convex grating in an Offner configuration to produce a nearly distortion free image. The sensor, which was constructed entirely from commercially available components, has been successfully deployed during several oceanographic experiments in 1999-2001. ... |
