Abstract. During the BIOSOPE field campaign October–December 2004, measurements of inherent optical properties from surface to 500 m depth were made with a ship profiler at stations covering over 8000 km through Southeast Pacific Ocean. Data ~3000 section containing very clearest waters in central gyre are reported here. The total volume scattering function 117°, βt(117°), was measured WET Labs ECO-BB3 sensor 462, 532, and 650 nm estimated uncertainties 2×10-5, 5×10-6, 2×10-6 m−1 sr−1,...

In this study, the potential of wind and solar power to reliably meet electricity demand New England is evaluated, as well role energy storage in improving reliability region's renewable system. Using 44 years hourly weather data from 1980 2023 obtained NASA MERRA-2 reanalysis product, variability these resources their impact on supply investigated. With varying mixes sufficient capacity generate equal annual demand, we find that a wind-dominant system can approximately 73% whereas...

Optical variability occurs in the near‐surface and upper ocean on very short time space scales (e.g., milliseconds millimeters less) as well greater scales. This is caused by solar, meteorological, other physical forcing biological chemical processes that affect optical properties their distributions, which turn control propagation of light across air‐sea interface within ocean. Recent developments several technologies modeling capabilities have enabled investigation a variety fundamental...
