Sea Spray and Icing in the Emerging Open Water of the Arctic Ocean
With the sea ice cover in the Arctic Ocean declining, the more extensive areas of open water will foster more frequent storms, higher winds, and bigger waves. These conditions can create copious amounts of sea spray. We anticipate that structures placed in shallow water wind turbines or drilling rig...

With the sea ice cover in the Arctic Ocean declining, the more extensive areas of open water will foster more frequent storms, higher winds, and bigger waves. These conditions can create copious amounts of sea spray. We anticipate that structures placed in shallow water wind turbines or drilling rigs, for instance will, therefore, experience more episodes of freezing spray that will create hazards for both personnel on these structures and for the structures themselves. Few observations, however, have been made of sea spray generation in high winds above, say, 15 20 m/s; and no spray observations have been made in freezing temperatures. Our objective is, thus, to observe the size distribution and rate of creation of spray droplets at air temperatures below freezing and in winds above 15 m/s and, preferably, above 20 m/s.
