The NOAA-led Arctic Report Card was released today. The annual assessment of change in the Arctic shows the region continues to outpace the rest of the globe in response to climate change, warming at twice the rate of anywhere else on earth.
The report documents changes in air temperature, sea surface temperature, snow cover, sea ice extent, the Greenland ice sheet, ocean productivity, and vegetation over the tundra. A special addition this year includes an assessment of polar bear population dynamics in several different regions of the Arctic.

Researchers are looking to the past to gain a clearer picture of what the future holds for ice in the Arctic. A project to analyze and digitize ship logs dating back to the 1850's aims to lengthen the timeline of recorded ice data.
Nearly 10 years ago, the world woke the day after Christmas to news of the most deadly tsunami in recorded history. Click to read more about PMEL's contribution to warning products to improve tsunami preparedness.
Sea snails that build aragonite shells are also known as pteropods. They are a prolific upper-ocean zooplankton, especially abundant in high-latitudinal environments in the Arctic and the Southern Ocean but also found in highly productive upwelling regimes such as the California Current System. They represent a food source for higher trophic levels, including varieties of fish, birds, and whales, and they play a key role in energy transfer and carbon fluxes in these regions by exerting a... more
