The Irminger Gyre: Circulation, convection, and interannual variability (2011, background): “As lLSW formation ceased and the subpolar gyre contracted through the 1990s, increased flow of warm, saline subtropical water into the eastern part of the North Atlantic ensued (Hátún et al., 2005; Sarafanov et al., 2008).”
A biological consequence of reducing Arctic ice cover: arrival of the Pacific diatom Neodenticula seminae in the North Atlantic for the first time in 800 000 years (2007, background): “In the North Atlantic, in contrast, the distribution is largely restricted to a much smaller area in the western Atlantic, a pattern that closely fits the observation by Hátún et al. (2005) that the circulation of the subpolar gyre retreated to the western basins from the mid-1990s.”
Temperature (2019, neutral): “The sub-polar Gyre is a key circulation feature in the North Atlantic and its expansion and contraction are linked to warming and cooling phases as well as changes in the strength of important currents in the North Atlantic system (Hátún et al., 2005).”
Solar forcing of North Atlantic surface temperature and salinity over the past millennium (2014, neutral): “Previous modelling and palaeodata studies have interpreted changes in the hydrographic properties of the NAC, and particularly salinity south of Iceland, to be controlled by frontal mixing resulting from changes in the spatial extent of the SPG as a response to changes in its strength 9,13 .”
Predicted slowdown in the rate of Atlantic sea ice loss (2015, background): “…Atlantic Water across the Iceland-Scotland ridge [Hátún et al., 2005; Holliday et al., 2008; Eldevik et al., 2009; Glessmer et al., 2014] that in turn have been associated with slow modulations in the strength, shape, and heat content of the SPG [Hátún et al., 2005; Nakanowatari et al., 2014].”
Climate-related variations in the occurrence and distribution of mackerel (Scomber scombrus) in Icelandic waters (2012, background): “the northern North Atlantic, whereas local conditions affect smaller scales (Malmberg and Kristmannsson, 1992; Jonsson and Valdimarsson, 2005; Hátún et al., 2005).”
Response of the North Atlantic subpolar gyre to persistent North Atlantic oscillation like forcing (2009, methodology): “Horizontal grid spacing might play a role, since Hatun et al. (2005) using a nested and higher (20 km) resolution version of an OGCM similar to the one used in this study obtain a better agreement between the simulated and observed North Atlantic gyre circulation strength.”
The North Atlantic subpolar circulation in an eddy-resolving global ocean model (2015, result): “Theweakening trend in the subpolar circulation has also been found in previous studies (Hátún et al., 2005) and coincides with a period of rapid warming that characterised the SPG in the mid 1990s ig.”
Bi-decadal variability excited in the coupled ocean–atmosphere system by strong tropical volcanic eruptions (2012, background): “Warm (cold) ENSO identifies quasi uniform warmer (colder) than average SSTs over the tropical Pacific (Fig. 3a), suggesting a bias towards ‘‘Central Pacific’’ type El Nin ˜os (e.g., Kao and Yu 2009 )a s commonly featured by IPCC AR4 models ( Guilyardi 2006 ).”
World ocean heat content and thermosteric sea level change (0–2000 m), 1955–2010 (2012, background): “Hatún et al. [2005] noted that the subarctic Atlantic Ocean began warming in 1995 after a period of cooling that began in the 1970s.”
Variability of the Atlantic meridional overturning circulation in CCSM4 (2012, neutral): “These features appear to be inconsistent with some recent observational studies (e.g., Hatun et al. 2005; Bersch et al. 2007), which find warm and salty anomalies in the upper ocean and a contracting SPG following reductions in the Labrador Seawater formation and in AMOC.”
Migration and wintering of a declining seabird, the thick-billed murre Uria lomvia, on an ocean basin scale: Conservation implications (2016, background): “Year-to-year variation in strength of the Subpolar Gyre (Hátún et al., 2005) affecting conditions in the Irminger and Labrador Seas and around South Greenland has been specifically linked to the decline in Svalbardmurres (Descamps et al., 2013).”
Large bio-geographical shifts in the north-eastern Atlantic Ocean: From the subpolar gyre, via plankton, to blue whiting and pilot whales (2009, methodology): “Annual averages of: the Atlantic Multi-decadal Oscillation (AMO) (Enfield et al., 2001), the SST west of the British Isles (Rayner et al., 2006) (see text), the inverted gyre index (GI) ( Hatun et al., 2005b ) and the North Atlantic Oscillation (NAO, inverted) (http://www.cdc.noaa.gov) are shown.”
