Spatiotemporal underwater light field fluctuations in the open ocean

Spatiotemporal underwater light field fluctuations in the open ocean

The light availability in the upper layer of the open sea is subject to strong fluctuations due to focusing of surface waves. This paper shows measurements of downwelling spectral irradiances as well as spatiotemporal light field patterns along the water column. Results are interpreted with respect to diverse surface waves. Direct wind develops capillary and small gravity waves that affect the ...

Persistent Ocean Monitoring with Underwater Gliders: Adapting Spatiotemporal Sampling Resolution

Ocean processes are dynamic, complex, and occur on multiple spatial and temporal scales. To obtain a synoptic view of such processes, ocean scientists collect data over long time periods. Historically, measurements were continually provided by fixed sensors, e.g., moorings, or gathered from ships. Recently, an increase in the utilization of autonomous underwater vehicles has enabled a more dyna...

11: Wave-Induced Fluctuations in Underwater Light Field: Analysis of Data From RaDyO Experiments

We investigate fluctuations in underwater light field produced by sea surface waves under various boundary conditions. Our objectives focus on the characterization of wave-induced fluctuations in downwelling irradiance and radiance as a function of various environmental parameters and depth of observation. The central theme of our study is to characterize the most intense light fluctuations at ...
