The latest temperature and salinity data for L4 and E1 are now available as easy to view plots. The above shows the series for 2016 (asterisks) compared with the average (solid line: period 1903 – present) and standard deviation (dashed line). As for 2015 the winter and autumn were markedly warm with a cooler spring period. This is reflected throughout the water column.
The salinity at E1 was on average about 0.1 PSU above the long-term average, possibly indicative of a dry year and / or greater influence of open Atlantic water pushing in from the west.
