Monthly SST anomalies 1920–2016
August 30, 2017

New research confirms that links between warm and cool years in the California Current System and El Niño are important but imperfect.  

sea surface height anomalies and upper-ocean temperature from the NOAA Kuroshio Extension Observatory
April 26, 2017

Approximately seven years of daily-averaged autonomous CO2 observations from NOAA’s Kuroshio Extension Observatory surface mooring were used to close the mixed-layer carbon budget, finding high rates of net community production during the spring bloom period.

Warm Blob
March 3, 2017

New research shows the extent and development of 'the Blob' using satellite surface temperature data to reveal warm temperature anomalies appearing as early as March 2014 in the central and southern California coast, and eventually extending to the entire West Coast and dissipating in August 2016.

Salinity and atmospheric circulation
June 2, 2016

Ocean-to-land moisture transport leaves an imprint on sea surface salinity, making this “nature’s rain gauge” to measure the variations of the water cycle. Two new studies provide strong evidence that salinity in the subtropical North Atlantic is a skillful predictor for precipitation in the African Sahel and the US Midwest.

Small island nations aridity
April 19, 2016

Future changes in freshwater availability are a major concern in the context of climate change. New research finds that overall changes to island freshwater balance will shift towards greater aridity for over 73% of 80 globally distributed island groups identified, impacting 16 million people by mid-century.

Arctic sea ice schematic
February 11, 2016

The fate of sea ice in the Arctic Ocean in the coming years and decades is dependent upon our understanding of the complex ocean–ice–air interactions and feedbacks to the system. A new paper by Carmack et al. identifies the critical processes, key questions, and required elements for a research agenda to study this new Arctic environment.

Warming in Norht Atlantic
January 4, 2016

In the Northwest Atlantic, the ensemble of global climate models has a warm bias in sea surface temperature due to a misrepresentation of the Gulf Stream position; thus, existing climate change projections could be underestimating the warming rate in the upper ocean by two to three times, according to new research by Saba et al.

AMOC impacts on biogeochemistry
December 8, 2015

The underlying physical driver for the decadal variability in the Gulf Stream path and the regional biogeochemical cycling is linked to the low-frequency variability of the large-scale ocean circulation in the Atlantic, also known as Atlantic meridional overturning circulation (AMOC).

Sea surface temperatures Pacific Ocean 2015
May 20, 2015

As of spring 2015, a wide strip of relatively warm water was present along the entire West Coast of North America. The causes and effects of this warm ocean water event is sometimes referred to as the “blob” and are the results of a new paper in Geophysical Research Letters.
