    • 2 (8, 11). Upon recovery, cup samples were frozen after removal of swimmers (mobile fauna) and later analyzed in duplicate for total carbon, with a Perkin-Elmer elemental analyzer, and inorganic carbon, with a Coulometrics carbon analyzer with corrections for salinity (8). Organic carbon was calculated as the difference between total and inorganic carbon.

    • Macrozooplankton volumes were calculated from net tows carried out during California Cooperative Oceanic Fisheries Investigations (CalCOFl) cruises between March 1990 and October 1996. Data were averaged from tows on lines 77, 80, 83, 87, 90, and 93 at stations 70 through 100, all of which are located at least 30 miles offshore. Macrozooplankton were collected in oblique net tows from 210 m depth to the surface. A summary of the procedures used to determine macrozooplankton volume can be found at www-mlrg.ucsd.edu/calcofi.html and in D. Kramer, M. J. Kalin, E. G. Stevens, J. R. Thrailkill, J. R. Zweifel, NOAA Technical Report NMFS CIRC-370 (1972).
