Abstract: Ice-Tethered Profilers (ITP), deployed in the Arctic Ocean between 2004 and 2013, have provided detailed temperature and salinity measurements of an assortment of halocline eddies. A total of 127 mesoscale eddies have been detected, 95% of which were anticyclones, the majority of which had anomalously cold cores. These cold-core anticyclonic eddies were observed in the Beaufort Gyre region (Canadian water eddies) and the vicinity of the Transpolar Drift Stream (Eurasian water eddies). An Arctic-wide calculatio… Show more

“…Approximately the same ratio of eddy polarization was found at mooring M1g, with 12 out of 23 eddies (or 52%) being cyclonic. This almost equal partitioning of eddies between cyclonic and 5 anticyclonic is in contrast with the findings by Woodgate et al (2001), who reported a larger amount of anticyclonic eddies compared to cyclonic eddies at the Lomonosov Ridge, as well as Zhao et al (2014), who found anticyclonic predominance for halocline eddies in the deep EB. We cannot explain this difference in ratios between cyclonic and anticyclonic eddies at the EB slope and in the deep Eurasian and Canadian basins.…”

“…The warming and freshening trend in the Pacific-water layer has already been reported by many studies [e.g., Proshutinsky et al, 2009;Jackson et al, 2010;Giles et al, 2012;Timmermans et al, 2014]. The cooling trend in the central Canada basin and the warming trend along its southern perimeter is a consequence of deepening of the warm Atlantic Water in the central basin and concurrent upwelling of warm Atlantic Water at the boundaries, a manifestation of an intensification of the anticyclonic Beaufort Gyre in recent years [e.g., McLaughlin et al, 2009;Karcher et al, 2012;Zhong and Zhao, 2014].…”

“…The autocorrelation at zero (Fig. 12a, c) show smaller values (0.6 -0.7) in the upper 100 m depth range, indicating active mesoscale processes (e.g., eddy activity observed in the Pacific-water layer [e.g., Zhao et al, 2014]). The zero-lag autocorrelations for spatial (Fig.…”

“…Note that the estimation of the autocorrelation quantifies basin-scale variability. Smaller-scale variability (e.g., mesoscale eddies on the deformation scale; Zhao et al, 2014) remains unresolved and is an intrinsic part of the autocorrelation function. The study area is the Amerasian Basin.…”
