I asked Nate Mantua of NOAA’s Southwest Fisheries Science Center to comment on the 1977 California Drought event in relation to the more recent “Blob” event of 2013. “The 1977 drought is very well known in the Pacific climate research community, and in the water resources world in CA-OR-WA because it was so extreme. Like our recent west coast drought, the proximate cause was a remarkably … Continue reading How does the 1977 climate event and related California drought of that period compare to the “Blob” event from 2013?
Those who follow North Pacific temperature patterns closely are well aware that the past summer brought a dramatic expansion of above-normal temperatures at the ocean surface across the northern North Pacific Ocean, reversing the cold anomalies that developed last winter during the strong El Niño episode. The two maps below illustrate the change, based on OIv2 SST data. The late winter pattern was very characteristic … Continue reading Subsurface Conditions

The Pacific Anomalies Workshop II, which was held in Seattle, Washington in January 2016 has a published report summarizing the current understanding of the “Blob” and its impact on the marine ecosystem along the US Pacific coastline, from Alaska to the Baja Peninsula. This report is available for download or viewing online to the public. PAWS II Workshop Report from January 2016 Presentations and video … Continue reading Pacific Anomalies Workshop II Report Is Published and Available to the Public
New research based on ocean models and near real-time data from autonomous gliders indicates that the “The Blob” and El Niño together strongly depressed productivity off the West Coast, with The Blob driving most of the impact. To read the whole recent summary, visit eco. Continue reading ‘The Blob’ Overshadows El Nino, (ecomagazine.com)
This is not really directly related to the Blob; however, it is likely these kinds of phenomena will vary from the norm during years experiencing events like warm pools similar to the Blob. Having a series of imagery throughout time will prove highly valuable at helping assess large-scale impacts on the oceanography of regions during anomalous years. From NASA’s Earth Observatory website, check out this story on … Continue reading “There’s more than one way to feed a phytoplankton bloom in the Gulf of Alaska”
The JISAO PDO index for May declined slightly from April, to +2.35. However, that’s still the highest value of record for May, edging out +2.32 in May 1940. The spring (Mar-May) mean value was +2.46 is by far the highest in the past 117 years (for the JISAO time series). JISAO is the Joint Institute for the Study of Atmosphere and Ocean.
