North Atlantic Bloom Experiment Cruises
U.S. participation in the North Atlantic Bloom Experiment consisted
of three cruises to several study sites along 20° W and north
of 40° N in the northeastern Atlantic. During the Spring of
1989, these process-oriented cruises monitored the annually occurring
phytoplankton bloom to track the fluxes of the biogeochemical system.
Hydrographic data from the North Atlantic Bloom Experiment cruises
have been combined into three comprehensive data products. The U.S.
JGOFS Data Management Office compiled the Niskin bottle and CTD data
products from the three process-oriented cruises listed in the table
below. It is important to note that in creating the CTD synthesized
product, the DMO translated some of the parameter names in order to
make them consistent for all the basin studies. Specifically, beam_c
was renamed beam_cp and re_fluor and fluor were
renamed fluor_re in the merged data product.
The Niskin bottle data product only includes data from the Atlantis
II cruises (AT119 legs 4 and 5) listed in the table below. There was
no base Niskin bottle data reported from the Endeavor cruise.
