Satellite measurements of chlorophyll distribution during spring 2005 in the California Current
Open accessAbstract
Eight years of satellite data quantify spring 2005 surface chlorophyll‐a (chl‐a) anomalies in coastal areas of the California Current. Negative anomalies <−1.0 mg m−3 begin in March north of ∼47°N, spread south to 43°N in April and 40°N in May and June 2005, maximum (<−2.0 mg m−3) north of 45°N. Positive chlorophyll anomalies dominate from ∼40°N to 27°N during this period. Strongest negative wind stress and positive coastal surface temperature anomalies are located south of maximum chl‐a anomalies, in the region of maximum climatological summer wind stress. Despite the magnitude of these wind anomalies, they remain upwelling‐favorable and negative chl‐a anomalies are in higher latitude regions of weaker wind anomalies, sufficient however, to prolong winter downwelling, delaying the onset of spring upwelling. In June, winds across the entire region become strongly upwelling favorable and by July, chl‐a anomalies switch to positive.

In 2005 in the California Current, a significant delay in the spring transition appears to have led to ecosystem changes affecting primary production, zooplankton, fish, birds, and mammals.
“This was particularly evident in 2005 in the California Current, when a significant delay in the spring transition [77,78] appears to have led to ecosystem changes affecting primary production [79], to zooplankton [80], to fish, birds, and mammals [81][82][83].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
