Why We Go North

Why We Go North

This blog post by Jeremy Mathis, director of NOAA's Arctic Research Program, is the first in a series of posts from NOAA scientists aboard US Coast Guard Cutter Healy who are measuring Arctic environmental change.

NOAA scientists set sail on Coast Guard icebreaker to measure change in the Arctic

NOAA scientists set sail on Coast Guard icebreaker to measure change in the Arctic

On Friday, August 25, U.S. Coast Guard Cutter Healy will sail from Dutch Harbor, Alaska, with a team of NOAA scientists and collaborators on a 22-day cruise to study environmental change in the western Arctic Ocean.

Sailing drone captures dawn while crossing the Bering Strait

In the early hours of August 1, one of two remotely operated unmanned sailing vehicles snapped this dreamy photo as it sailed through the choppy Bering Strait, bound for a voyage of data collection. In the distance are the islands of Little Diomede in the United States and Big Diomede in Russia.

Summer of sailing drones

Summer of sailing drones

Over the next four months, NOAA scientists will launch unmanned ocean vehicles, called Saildrones, from the Arctic to the tropical Pacific Ocean to help better understand how changes in the ocean are affecting weather, climate, fisheries and marine mammals. The wind and solar-powered research vehicles that resemble a sailboat will travel thousands of miles across the ocean, reaching some areas never before surveyed with such specialized technology.

Research shows ocean acidification is spreading rapidly in the Arctic

Research shows ocean acidification is spreading rapidly in the Arctic

Ocean acidification is spreading rapidly in the western Arctic Ocean in both area and depth, potentially affecting shellfish, other marine species in the food web, and communities that depend on these resources, according to new research published in Nature Climate Change by NOAA, Chinese marine scientists and other partners.

NOAA is transforming science with unmanned systems

NOAA is transforming science with unmanned systems

At first glance they might be mistaken for toys, but these remote-controlled devices aren’t for play. Unmanned aircraft and watercraft are being put to work by NOAA scientists to gather astonishing new data from our wildlands and waterways.

As Alaska warms, methane emissions appear stable

As Alaska warms, methane emissions appear stable

Analysis of nearly three decades of air samples from Alaska’s North Slope shows little change in long-term methane emissions despite significant Arctic warming over that time period, according to new research published in Geophysical Research Letters.

Q&A: What do Arctic ice and Atlantic hurricanes have in common?

Q&A: What do Arctic ice and Atlantic hurricanes have in common?

The journal Nature Geoscience published a paper by Tom Delworth and his colleagues examining how a natural atmospheric force--the North Atlantic Oscillation--may be changing ocean currents in the North Atlantic. Among other impacts, the stronger ocean currents increase the amount of heat flowing toward polar areas, which could speed up Arctic ice melt and affect how hurricanes form. We asked Delworth a few questions about his study:

New study: Sea ice loss likely no factor in cold Northern Hemisphere winters

New study: Sea ice loss likely no factor in cold Northern Hemisphere winters

The rapid loss of Arctic sea ice is a major driver of the warming trend sweeping across the Arctic in recent  years, but melting sea ice is probably not behind recent cold winters in parts of Europe, Asia, and the United States, according to a new NOAA study.

Arctic set for record-breaking melt this summer

Arctic set for record-breaking melt this summer

The record heat baking Alaska is poised to smash a host of climate records in 2016, including the earliest snowmelt date at NOAA’s Barrow Observatory, the northernmost point in the nation.
