Autonomous Multi-Vehicle System Designed for Long-Term Arctic Studies
Computer Science. “Additionally, there remains much to uncover about Arctic phytoplankton and algae, which play a crucial role in the food web and influence ocean-atmosphere interactions. This new system could enhance our scientific understanding of their ecological significance while supporting Alaska’s indigenous communities in adapting to future changes in wildlife and food resources.&rdquo
Padilla, Murkowski Introduce Bill for Atmospheric River Forecasting
U.S. Senators Alex Padilla (D-Calif.) and Lisa Murkowski (R-Alaska) have announced bipartisan legislation that will reduce flood risks and bolster emergency preparedness by improving atmospheric river forecasting to predict the timing and location of these storms more precisely. The Improving Atmospheric River Forecasts Act would require the National Oceanic and Atmospheric Administration (NOAA) to establish a forecast improvement program within the National Weather Service. The legislation was announced as major atmospheric river storms bring high winds, heavy rain, and snowfall to California
NOAA Expands Water Level and Wave Dataset
so they can better prepare and respond to future events.”NOAA scientists will integrate CORA’s historical datasets into existing products, including the Sea Level Calculator and High Tide Flooding Outlooks.NOAA plans to release Coastal Ocean Reanalysis datasets for the West Coast, Hawaii and Alaska by late 2026
Storm Chaser Cyrena Arnold to Sign Books at R.M. Young AMS 2025 Booth
(AMS) Annual Meeting, January 13–14, 2025.Arnold’s professional accomplishments begin back in 2006 when she received a NASA certificate of appreciation for her efforts towards aviation safety while employed at a NASA contractor, AirDat. She then installed weather stations on the remote Alaska tundra for six years with McVehil-Monnett Associates, then came to New Hampshire as the Director of Summit Operations for the non-profit Mount Washington Observatory and was an NH1 News TV Meteorologist. She has made guest appearances on WIRED, Good Morning America, Insider, USA Today, GQ, Popular
Podcast: Fascinated by Shipwrecks; USS Monitor Digitally Reimagined
. Tane’s specialties include 19th-century warships and deep-water archaeology, as well as building collaborative partnerships, public outreach and exhibit design. He has led NOAA archaeological expeditions in the Florida Keys, the Great Lakes, California, the Northwestern Hawaiian Islands, Alaska, and USS Monitor. He’s also participated in projects including a sunken Boeing B-29 Superfortress in Lake Mead, a Civil War blockade runner in Bermuda, USS Arizona, and was most recently part of an expedition to RMS Titanic. Tane’s projects have used technical diving, remotely operated
Most Coastal Arctic Infrastructure at Risk by 2100
can be compounded by other climate threats, such as changing weather patterns and land subsidence.“That can result in very important shifts in the coastline in some areas,” said Rodrigue Tanguy, a researcher at b.geos and first author on the study. “For example, along the coasts of Alaska, Canada and Siberia, there is a huge number of lakes on permafrost. If subsidence and erosion trigger breaches in these lakes, there will be a totally different coastal landscape.”The work was published in Earth’s Future
Seals Have Preferences for Different Icebergs
bergs for giving birth and caring for newborn pups, while in the molting season, they and the rest of the seal population favor speedier ice near the best foraging grounds. The study focused on harbor seals and icebergs in Johns Hopkins Inlet and Glacier, located in Glacier Bay National Park, Alaska. Johns Hopkins is one of the few glaciers on Earth that is advancing (growing thicker and flowing forward into the fjord) rather than retreating due to global warming, partly thanks to its terminal moraine, comprising crushed rock and other sediment, which effectively barricades the front of the
The Power of Scientific Collaboration is Perennial
for it.The importance of the work is that it suggests that as deserts release dust into the air and as that dust settles on the ocean's surface, it could help phytoplankton growth, potentially increasing the amount of CO2 the ocean absorbs from the atmosphere.On CO2, researchers at the University of Alaska Fairbanks have developed a sensor that measures CO2 in the ocean, and they have made their design, published in the journal Ocean Science, available to the scientific community. Installed on an unmanned underwater vehicle, the sensor can provide high spatial and temporal resolution data for weeks
New CO2 Sensor Added to Seaglider
Researchers at the University of Alaska Fairbanks (UAF) and their industry partners have advanced the technology available to measure carbon dioxide in the ocean.Their design, published in the journal Ocean Science, is now available to the scientific community.During the past six years, a team from the UAF International Arctic Research Center and private companies developed a way to equip an unmanned, underwater vehicle called a Seaglider with a sensor that monitors carbon dioxide. The sensor communicates with a satellite to provide high spatial and temporal resolution data for weeks at a time.IARC&rsqu
