A new study finds that an area of the Arctic Ocean critical for the survival of polar bears is fast becoming vulnerable to climate change.

The region, dubbed the “last ice area” had been expected to stay frozen far longer than other parts of the Arctic.

But this new analysis says that this area suffered record melting last summer.

The researchers say that high winds allied to a changing climate were behind the unexpected decline.

The objectives of this research are to quantify the connection between seasonal warming of arctic surface waters and the absorption of solar energy, and additionally to identify the presence and seasonal cycling of materials responsible for this absorption. Seasonal changes in the attenuation of solar radiation within the sea ice and upper 30m of the water column will be measured at high temporal resolution (hourly) by a new proof of concept buoy system. Temperature and PAR (photosynthetically active radiation) irradiance measurements will be made using optical sensors paired with thermisters within the water column and sea ice. A fluorometer will…

Observations of surface air pressure (SAP) and surface air temperature (SAT) provide the foundation of our ability to forecast weather and ice conditions, and our ability to understand the earth’s climate and climate change. These basic variables are monitored through out the globe by weather stations on land, moored buoys along the coast, and drifting buoys in most of the world’s oceans. However, the Southern Ocean and sea ice around Antarctica continue to be one of the least sampled areas of the planet. This lack of observations around Antarctica hinders our ability to accurately predict weather (Bromwich and Cassano, 2001),…

Recent years have seen extreme changes in the Arctic sea ice cover and adjacent open ocean – reduced ice extent, record sea surface temperatures, thinner and younger ice, and loss of ice in areas that had been ice-covered throughout human memory.Particularly striking are changes within marginal ice zones (MIZ) – areas that are becoming increasingly covered by low concentration, diffuse sea ice.The proposed work, referred to here as the “Marginal Ice Zone Ocean and Ice Observations and Processes Experiment (MIZOPEX)”, brings to bear the capabilities of unmanned aircraft systems (UAS) in concert with in-situ observations and satellite remote sensing to…
