Helaas heb ik momenteel te weinig tijd en inzicht om er echt diep op in te gaan. Om er echt kritisch naar te kunnen kijken, heb je toch wel kennis van eerdere publicaties e.d. nodig. Iemand anders wellicht?
Volgens de auteurs iig:
When
highly reflective sea ice is replaced by open water during the ice
melting period, there is a substantial solar heat input directly into
the ocean, increasing the heat stored in the upper ocean. For example, the cumulative solar heat input in the Beaufort Sea during
the ice melting period in 2007 can be a factor of two to five higher
than climatology, which is sufficient to warm the upper 5 m of
the ocean by 5 °C (24). The loss of sea ice in the Canada basin
has also been accompanied by the widespread appearance of a
near-surface temperature maximum at 25- to 35-m depth due to
penetrating solar radiation (25). Warming of the upper ocean retards the recovery of sea ice during the fall freeze-up. As a result,
the ice coverage in late autumn and early winter for the past few
years is significantly below the mean of 1979–2000, exceeding two
standard deviation of ice variability (Fig. S3). The anomalously
warm, ice-free ocean water increases the ocean surface flux of
heat and moisture into the atmosphere in late autumn and early
winter, which in turn has substantial impacts on winter atmospheric circulation.
