Fall 2009 Update: Spring Sea Surface Temperature Distribution

The progression of spring sea surface temperatures for the months of January through June are shown in the left hand set of panels. Higher SSTs appear as warm shades whereas low SSTs appear as cool shades. The right hand set of panels show exceptional anomalies of SST, those tending to exceed plus or minus one quarter of a standard deviation of the overall SST for the field. This type of anomaly tends to highlight high SSTs in an area, the red shades, and low SSTs in an area, the blue shades. The progression of spring warming was generally at average levels for most of the Northeast Shelf with the exception of warm conditions that were established during May. This warming took place over much of the shelf, but as indicated by the pink tones, it was not a pattern of strong or consistent warming. By June there was some indication that the mid shelf region had actually cooled, most likely related to shifting weather patterns in the region.
