The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.
Increase your understanding of the Federal Register eco-system and improve your FederalRegister.gov skills with these helpful, unofficial educational articles and videos. See more of our reader aids here.
Section 22214 of the Bipartisan Infrastructure Law (BIL) of 2021 tasks the Federal Railroad Administration (FRA), under delegation from the Secretary of Transportation, with conducting an Amtrak Daily Long-Distance Service Study to evaluate the restoration of daily intercity passenger rail service and the potential for new Amtrak long-distance routes. Under BIL, FRA is required to conduct a study to assess the restoration of daily intercity rail passenger service along any Amtrak long-distance routes that were discontinued, as well as any Amtrak long-distance routes with nondaily service. In evaluating intercity passenger rail routes, FRA may assess potential new Amtrak long-distance routes. This includes routes in service as of April 1971 but not continued by Amtrak, taking into consideration whether those new routes would:
FRA has been engaging with and listening to stakeholders, including transportation and rail partners, federally recognized tribes, and communities, to evaluate how to better connect people with long-distance rail services. Stakeholder engagement for the Long-Distance Service Study began in September 2022 and will continue throughout 2023 and part of 2024.
Sea ice data is updated daily, with a one-day lag. The orange line in extent and concentration images (left and middle) and the gray line in the time series (right) indicate 1981 to 2010 average extent for the day shown. The graph also includes lines for selected earlier years, for comparison. Learn about update delays and other problems which occasionally occur in near-real-time data. Read about the data.
July is the warmest month in the Arctic and hence also the month of peak sea ice loss. As of the middle of July 2024, extent is declining at an above average pace. Sea is mostly gone in Hudson Bay, and there has been extensive retreat in the Barents and Laptev Seas. Satellite data reveal a small area of unusually dense sea ice formed last winter near Wrangel Island.
On July 15, 2024, halfway through the month, sea ice extent stood at 8.16 million square kilometers (3.15 million square miles), ranking seventh lowest in the satellite passive microwave record for that date. The rate of ice loss from July 1 to July 15 of 121,000 square kilometers (47,000 square miles) per day was above the average value of 89,000 square kilometers (34,000 square miles) per day. As assessed using the NSIDC sea ice spatial comparison tool, ice losses over the past two weeks have been most notable along the Eurasian coast, particularly over the northern Barents and Laptev Seas (Figure 1b). Some ice still remains in western Hudson Bay. Data from the Advanced Microwave Scanning Radiometer 2 (AMSR-2) instrument aboard the Japan Aerospace Exploration Agency (JAXA) Global Change Observation Mission-Water (GCOM-W) satellite shows areas of low concentration ice north of Alaska and in the East Siberian Sea, interspersed with areas of more compact ice, especially south and east of Wrangel Island (Figure 1c). Ice over the central Arctic Ocean remains compact.
Air temperature at the 925 hPa level (about 2,500 feet above the surface) averaged over the first two weeks of July was 2 to 6 degrees Celsius (4 to 11 degrees Fahrenheit) above average over the Laptev Sea, where substantial sea ice losses have been observed so far in the month (Figure 2a). Temperatures were also 2 to 4 degrees Celsius (4 to 7 degrees Fahrenheit) below average extending from the East Siberian Sea, across the Beaufort Sea, and in the western Canadian Arctic Archipelago. In contrast to June 2024, which was characterized by a strong Beaufort High, the sea level pattern for the first two weeks of July 2024 features below average pressure covering much of the Arctic Ocean, with a small area of above-average pressures centered over the Laptev Sea (Figure 2b).
Colleagues at the University of Washington Polar Science Center maintain maps of sea surface temperature over the Arctic region. Fairly high sea surface temperatures of 3 to 5 degrees Celsius (37 to 41 degrees Fahrenheit) prevail along parts of the Siberian coast where the sea ice retreated earlier this season. Fairly warm waters are also creeping into the eastern Chukchi Sea.
Winds from the east-southeast in spring have tightly packed sea ice between Wrangel Island and mainland Siberia. Sea ice concentrations in this wedge-shaped area in the Advanced Microwave Scanning Radiometer 2 (AMSR-2) mapping is higher than the other regions along the Siberian coast (Figure 1c). The area on the downwind side of open water can be seen both in the AMSR-2 mapping and in an image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite from July 7 (Figure 4a). Looking back at the sea level pressure field from earlier in the season, June 1 to June 15, points to winds that would compact sea ice into this region between the island and the mainland (Figure 4b).
Ice concentrations in this area appear to be nearly 100 percent. This sea ice also appears to be especially thick, 1.5 meters (4.9 feet) above average, as depicted in the June fields from the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS).
Arctic Sea Ice News & Analysis (ASINA) is produced by the National Snow and Ice Data Center (NSIDC), which is part of the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder. Researchers Walt Meier, Ted Scambos, Mark Serreze, and Julienne Stroeve regularly contribute to ASINA, sometimes featuring guest authors, and with support from Kevin Beam, Andy Barrett, Lisa Booker, Michael Brandt, Florence Fetterer, Matt Fisher, Agnieszka Gautier, Marin Klinger, Jonathan Kovarik, Jed Lenetsky, Luis Espinosa Lopez, Audrey Payne, Bruce Raup, Matt Savoie, Trey Stafford, Bruce Wallin, and Ann Windnagel.
The NASA award NNX16AJ92G funds the ASINA project. The sea ice data for the Sea Ice Index are from the NASA Snow and Ice Distributed Active Archive Center (DAAC), which is funded by NASA award 80GSFC18C0102, and from the CIRES cooperative agreement with NOAA, which is funded by NOAA NA15OAR4320137.
A Wisconsin State Park System vehicle admission sticker is required on all motor vehicles stopping in state parks, forests and recreation areas. Admission stickers can be purchased online or at most individual properties via drive-up window service, electronic sales kiosks or self-registration stations.
There's an additional $5 fee for anyone who fails to pay for admission before using the park, forest, trail or recreation area. If a visitor refuses or fails to buy a sticker/trail pass, a citation can be issued.
Buy online: The Department of Natural Resources has the option to purchase Wisconsin State Park vehicle admission stickers online. Annual and daily Wisconsin Resident, Annual Wisconsin Resident Senior and Nonresident Annual stickers can be purchased online. Additionally, one Reduced Rate Annual sticker (for a vehicle registered to the same household address) can be purchased online at the same time as a full-price sticker. An admission sticker or admission sticker package can be purchased one at a time through the online service. A combination of stickers/trail passes can be purchased in one transaction at a state park property.
