This paper describes my career in Ocean Optics over nearly half a century. It was centered around the Inherent Optical Properties (IOP, the scattering and absorption properties of sea water and its dissolved and suspended materials). The paper descri

The reflectance of the bottom is of importance when interpreting optical data in shallow water. Closure studies of radiative transfer, interpretation of laser line scanner data, lidar, and remote sensing in shallow waters require understanding of the

Measurements of inherent optical properties (IOP) were conducted over bottoms with different substrates by use of a sampling package mounted on and operated by a SCUBA diver. It was found that in areas of low ambient currents the distribution of IOP

Huge accumulations of diatom-dominated marine snow (aggregates >0.5 mm in diam- eter) were observed in a layer approximately 50 cm thick persisting over a 24 h period in a shallow fjord in the San Juan Islands, Washington, USA. The layer was associat

A new instrument package for measuring physical (temperature, salinity, and depth) as well as optical (absorption and attenuation at nine wavelength) parameters using SCUBA is described. The package is attached to the SCUBA bottle and allows for samp

A model based on Mie theory is described that estimates bulk participate refractive index n¯p from in situ optical measurements alone. Bulk refractive index is described in terms of the backscattering ratio and the hyperbolic slope of the particle s

Spectral attenuation and absorption coefficients of particulate matter and colocated hydrographic measurements were obtained in the Mid-Atlantic Bight during the fall of 1996 and the spring of 1997 as part of the Coastal Mixing and Optics experiment.

A new technique for measuring the light field within sea ice has been developed and deployed in first and multiyear ice. Portions of the radiance distribution are determined by profiling a 3° field-of-view radiance head at a number of zenith and azi

Measuring coastal and oceanic absorption coefficients of dissolved and particulate matter in the visible domain usually requires a methodology for amplifying the natural signal because conventional spectrophotometers lack the necessary sensitivity. T
