Bio-Optical Characteristics of the Northern Gulf of California during June 2008

Table 2

Average (minimum and maximum in parenthesis) values for each bio-optical region of first optical depth (1OD), chlorophyll- concentration (Chla), phytoplankton light absorption coefficient at 440 nm ((440)) and 675 nm ((675)), nonpigmented particles light absorption coefficient at 440 nm ((440)), percent contribution of nonpigmented particles to light absorption (%), reflectance at 560 nm (R(560)), and maximum reflectance ratio (MRR). In column “Region” number in parenthesis is the number of data used for average calculations for all data except R(560) and MRR. For these last two variables the number of data used for calculation is indicated at the right of the slash.
