Approximate net sea ice exchange (see legend for key to arrow sizes), extent of shorefast ice and winter sea ice, and coastal polynyas and main polynya concentrations Approximate net sea ice exchange (see legend for key to arrow sizes), extent of shorefast ice and winter sea ice, and coastal polynyas and main polynya concentrations
An example of a positive feedback loop Warming leads to a decrease in sea ice cover which in turn leads to a decrease in albedo over the ocean, the result of which is further warming and further decreases in the sea ice cover An example of a positive feedback loop Warming leads to a decrease in sea ice cover which in turn leads to a decrease in albedo over the ocean, the result of which is further warming and further [..]

Main sources of icebergs and common iceberg drift trajectories The main ice circulation pattern follows the Transpolar Drift in the eastern Arctic and the Beaufort Gyre in the western Arctic (white arrows) Main sources of icebergs and common iceberg drift trajectories The main ice circulation pattern follows the Transpolar Drift in the eastern Arctic and the Beaufort Gyre in the western Arctic (white [..]
The hydrologic balance in the Arctic is highly dynamic on the seasonal time scale with large and rapid ice melts in the spring On land, this ice and snow melting results in large rapid floods and surges in rivers The hydrologic balance in the Arctic is highly dynamic on the seasonal time scale with large and rapid ice melts in the spring On land, this ice and snow melting results in large rapid floods and [..]
Lower tropospheric temperatures since 1979, from satellite monitoring High variability is characteristic of the Arctic region due to its isolation from the moderating influences of warm, lower latitude, ocean currents Lower tropospheric temperatures since 1979, from satellite monitoring High variability is characteristic of the Arctic region due to its isolation from the moderating influences of warm, lower [..]

To refine your search you can combine your search strings with AND, OR, NOT and NEAR and phrases can be quoted:
water OR waste searches for either of these words
oceans AND biodiversity searches for blocks with both words
pollution NEAR water searches for blocks with either of these words, with them being closer ranks higher
"climate change" searches for this phrase
