A spectral model of scalar irradiance with depth is applied to calculations photosynthetically available radiation for a vertically homogeneous water column. The runs more than 14,000 times faster the full Hydrolight code, while it limits percentage error 2.20% and maximum less 4.78%. distribution incident sky radiance effects wind-roughened surface are integrated into this model. It can be case 1 waters as well 2 that happen gelbstoff rich, volume-scattering phase function generated...
The upwelling radiance distribution in optically shallow water is investigated with experiments and Hydrolight numerical simulations for two different benthic surfaces a range of solar zenith angles (≪60°). Over bright sand surface (water depth 5 m) the was brightest at nadir decreased toward horizon. nearly azimuthally symmetric but strongly influenced by wave focusing. Q ( E u /L , where irradiance L radiance) this case significantly less than π. 440 nm 670 nm, almost independent angle....
Recent increases in global urea usage, including its incorporation slow-release fertilizers commonly used lawn care Florida, have the potential to alter form and amount of nitrogen inputs coastal waters. This shift may, turn, impact phytoplankton community diversity nutrient cycling processes. An autonomous water quality monitoring sampling platform containing meteorological instrumentation, phycocyanin sensors, was deployed between June November 2009 Sarasota Bay, Florida. shallow, lagoonal...
Aircraft images were collected near Lee Stocking Island (LSI), Bahamas, with wavelike features for bright sand bottoms during times when solar zenith angles large. The image contrast between leading and trailing wave facets approached a 10–15% difference because of algae accumulations in troughs or topographic variations the bottom. Reflectance blue light was greater than red green wavelengths detritus present troughs. However, at caused by interplay bottom topography oblique illumination. A...
The U.S. Integrated Ocean Observing System is being designed to be an end-to Dend, integrated, sustained, operational of Systems that provides data, information and products benefit a broad range stakeholders in their decision-making. These design concepts form the basis pilot projects undertaken by Gulf Mexico Coastal Regional Association (GCOOS-RA). This paper presents case study GCOOS-RA Harmful Algal Bloom (HABIOS) Project. A set research activities related harmful algal blooms examined...
The ability to acquire information about inherent optical properties such as total spectral absorption (a((lambda) ), m<SUP>-1</SUP>) and scattering (b((lambda) from reflectance of oceanic waters is fundamental the development remote sensing algorithms. While considerable success has been achieved in relatively clear waters, inversion methods determine a((lambda) ) b((lambda) conjunction with profiles situ radiance at various locations off Cape Hatteras, North Carolina during spring 1996....
