An Unintentional Iron Fertilization Experiment
waters further and further away from Hawai‘i, Hawco said.“To the best we can tell, the impacts of anthropogenic iron on ecosystems is most intense in the North Pacific. During our cruises, bad weather prevented us from reaching beyond 42 north, but we expect that impacts would reach up to Alaska.”There are likely key areas of anthropogenic iron release in South America and Southern Africa that will grow over time, he says. It’s also likely that there were significant emissions during industrialization of the US east coast and throughout western Europe that would have added iron
Mother Ship with USV Flotilla Could Boost Coast Guard Capabilities
provide extended range monitoring and on-scene presence, possibly up to 400 NM. This could allow two or three flotillas to monitor the Labrador Sea from Newfoundland up through Baffin Bay. Similarly, one mother ship and flotilla could monitor much of Hudson Bay. Another application could be the Gulf of Alaska and the Bering Sea.The USVs could be controlled from the mother ship or operate autonomously under some conditions. They would be suitable and seaworthy for the purpose intended and could have sufficient fuel capacity for 40 to 60-day endurance at moderate speed.The mother ship may be reinforced
Satellite data from Ship Captures Landslide-Generated Tsunami
of the study. “Scientists have captured larger, earthquake-induced tsunamis using ship navigation systems. Our team had equipment in the right place at the right time to show this method also works for landslide-generated tsunamis.”On May 8, 2022, a landslide near the port city of Seward, Alaska, sent debris tumbling into Resurrection Bay, creating a series of small tsunami waves. The R/V Sikuliaq, a research ship owned by the National Science Foundation and operated by the University of Alaska Fairbanks, was moored 650 meters (0.4 miles) away. It was equipped with an external Global Navigation
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
