Daily Incident Photosynthetically Available Radiation (PAR) Measured during the JGOFS North Atlantic Bloom Experiment (NABE)Entry ID: JGOFS_NABE_PAR
Abstract: The Joint Global Ocean Flux Study (JGOFS) seeks to understand
the processes that control the transfer of carbon and other
biologically active elements in the ocean. In addition, JGOFS
hopes to improve global-scale predictions of the ocean's response to
human-inducded climate change.
The North Atlantic Bloom Experiment (NABE) ... was a multidisciplinary,
multinational pilot study of JGOFS, studying the spring phytoplankton
bloom in the North Atlantic and its associated biogeochemical
processes. It took place from April until July, 1989, on two cruises
of the RV Atlantis II and one cruise of the RV Endeavor. The stations
in the North Atlantic were located from 18N to 72N and from 8W to 47W.
Measurements of incident photosynthetically available radiation (PAR)
were integrated to daily values. The following values are given:
integrated daily incident PAR, peak incident PAR, integrated daily
spherical PAR, peak spherical PAR, and daily clear sky PAR. PAR units
are in moles per square meter; the peak PAR units are in moles per
second per square meter.
