Calibrated Near-Forward Volume Scattering Function Obtained From The Lisst Particle Sizer, Wayne H. Slade, Emmanuel S. Boss
Calibrated Near-Forward Volume Scattering Function Obtained From The Lisst Particle Sizer, Wayne H. Slade, Emmanuel S. Boss
Marine Sciences Faculty Scholarship
The physical nature of particles, such as size, shape, and composition govern their angular light scattering, which is described by the volume scattering function (VSF). Despite the fact that the VSF is one of the most important inherent optical properties, it has rarely been measured in aquatic environments since no commercial instrument exists to measure the full VSF in the field. The commonly used LISST (Laser In Situ Scattering and Transmissometry) particle sizer (Sequoia Scientific, http://www.sequoiasci.com) measures near-forward angular scattering of a laser source (λ = 670 nm) at 32 logarithmically-spaced photodetectors arranged between 0.08 and 15 degrees and inverts …
Hands-On Oceanography. Settling Of Particles In Aquatic Environments Low Reynolds Numbers, Emmanuel Boss, Lee Karp-Boss, Peter A. Jumars
Hands-On Oceanography. Settling Of Particles In Aquatic Environments Low Reynolds Numbers, Emmanuel Boss, Lee Karp-Boss, Peter A. Jumars
Marine Sciences Faculty Scholarship
The purpose of this activity is to familiarize students with how a particle’s size, shape and orientation affects its settling at low Reynolds numbers. This activity can also be used to teach statistical skills (e.g., replication of measurements, propagation of error, type I vs. type II regressions).
Potential Of Argo Drifters For Estimating Biological Production Within The Water Column, Seung Hyun Son, Emmanuel Boss, Jae Hoon Noh
Potential Of Argo Drifters For Estimating Biological Production Within The Water Column, Seung Hyun Son, Emmanuel Boss, Jae Hoon Noh
Marine Sciences Faculty Scholarship
Argo drifters provide information of the vertical structure in the water column and have a potential for the improvement of understanding phytoplankton primary production and biogeochemical cycles in combination with ocean color satellite data, which can obtain the horizontal distribution of phytoplankton biomass in the surface layer. Our examples show that using Argo drifters with satellite-measured horizontal distribution of phytoplankton biomass at the sea surface allow an improved understanding of the development of the spring bloom. The other possible uses of Argo drifter are discussed.
