Measuring the Sea Water Absorption Factor Using Integrating Sphere

Practical questions of quickly determining the sea water absorption factor using an integrating sphere are considered: measurement technique and data processing, as well as reference solution calibration. Numerical experiments using the Monte-Carlo method are performed to evaluate the influence of the device features (absence of spherical symmetry and the presence of a reflection specular component from the quartz shell) on the determination of the absorption factor considering scattering properties of the medium. Examples of how the results of the proposed technique can be used are given under the conditions of sea expeditions.
