Biological, chemical and radiochemical studies of marine plankton
Ketchum, Bostwick H.
From the introduction: Since the last progress report and research proposal was submitted
to the U.S. Atomic Energy Commission we have completed seven cruises
on which the primary objectives were the study of the biology, chemistry
and radiochemistry of marine plankton populations. As in the past, our
program of plankton research has been jointly sponsored by the Atomic
Energy Commission, by grants from the National Science Foundation, by
contract with the Office of Naval Research and by Institution funds.
Of the seven cruises mentioned above, three included a complete hydrographic
and zooplankton collecting section of 13 - 15 stations extending
from Montauk Point to the vicinity of Bermuda; one occupied the
first third of this section extending across the continental shelf to
the Gulf Stream, and three were for the purposes of specialized studies.
