Experimental studies on the optical properties of sea water

Abstract

Attenuation, absorption, and total scattering coefficients for sea water at 5300 A were obtained nearly simultaneously from experimental observations at the Argus Island tower in the North Atlantic Ocean and in Long Island Sound and Block Island Sound. A unique in situ instrument permitted scattering measurements at a minimum forward angle of 0.2°. Depth profiles of the three coefficients exhibit an over‐all agreement with simple theoretical prediction within a factor of 2. Coefficients measured in Long Island Sound were about a factor of 10 larger than those from the North Atlantic station, and coefficients from Block Island Sound were intermediate.

“…[8] The earliest treatment of the optical properties of LIS in the literature dates back to Morrison's [1970] study, and several studies have included optical data from LIS since then [Leathers et al, 1999;Gardner et al, 2001;Sosik et al, 2001;Morrison and Sosik, 2002;Werdell and Roesler, 2003;Etheridge and Roesler, 2004;Branco and Kremer, 2005;Ackleson, 2006]. Time series profiles of IOPs at the Race in 2000 and 2001 [Morrison and Sosik, 2002] showed twofold variability in the absorption properties of surface waters associated with tidal transport.…”
