Shown is the May 2015 monthly average Sea Surface Temperature (SST) anomaly showing 'the Blob' of record warm temperatures in the Pacific Ocean.  This image was generated by PO.DAAC using NASA's Multi-Scale Ultra-High Resolution (MUR) SST dataset. The image was featured on the cover of a recent Geophysical Research Letters journal in association with an article by Chelle Gentleman, a former PO.DAAC User Working Group member.
