Plankton Production Biology
Abstract
Mining existing data I have continued to investigate hydrography and nutrients in respect to plankton production in the central and eastern Arabian Sea and on the shelf off India's west coast. Occasionally I have commented on general oceanographic or ecological principles. The principal objective during FY2013 was the completion of a study of variability on daily to fourdecadal scales of dissolved oxygen and nitrite in the upper Oxygen Minimum Zone (OMZ) of the central Arabian Sea. The editing toward publication by India s National Institute of Oceanography of a translation from the Russian of Sazhina (1985) about the larvae (nauplii) of 86 common marine planktonic copepods was taken up again after the completion of the OMZ review. Under the second no-cost extension of the grant, together with Indian colleagues I have collected and evaluated essentially all discrete O2 data obtained by one mode of the Winkler procedure and all NO2 - measurements, besides temperature and salinity, from the same water bottles in the upper Oxygen Minimum Zone (OMZ). The data, taken between 1959 and 2004 from near 150, 200, 300, 400, and 500 m depth, were grouped in zonally-paired boxes of 1 lat. and 2 long. centered at 8 , 10 , 12 , 15 , 18 , 20 , and 21 N along 65 E and 67 E and the quality of the analyses checked by the accompanying NO2 - measurements.
