dc.description.abstract | The differences among phytoplankton carbon (Cphy) predictions from six ocean color
algorithms are investigated by comparison with in situ estimates of phytoplankton
carbon. The common satellite data used as input for the algorithms is the Ocean
Color Climate Change Initiative merged product. The matching in situ data are derived
from flow cytometric cell counts and per-cell carbon estimates for different types of
pico-phytoplankton. This combination of satellite and in situ data provides a relatively
large matching dataset (N > 500), which is independent from most of the algorithms
tested and spans almost two orders of magnitude in Cphy. Results show that not a single
algorithm outperforms any of the other when using all matching data. Concentrating
on the oligotrophic regions (Chlorophyll-a concentration, B, less than 0.15 mgChlm−3),
where flow cytometric analysis captures most of the phytoplankton biomass, reveals
significant differences in algorithm performance. The bias ranges from −35 to +150%
and unbiased root mean squared difference from 5 to 10 mgCm−3 among algorithms,
with chlorophyll-based algorithms performing better than the rest. The backscatteringbased
algorithms produce different results at the clearest waters and these differences
are discussed in terms of the different algorithms used for optical particle backscattering
coefficient (bbp) retrieval. | en_US |
