On 2022 February 15–16, multiple spacecraft measured one of the most intense solar energetic particle (SEP) events observed so far in Solar Cycle 25. This study provides an overview of interesting observations made by multiple spacecraft during this event. Parker Solar Probe (PSP) and BepiColombo were close to each other at 0.34–0.37 au (a radial separation of ∼0.03 au) as they were impacted by the flank of the associated coronal mass ejection (CME). At about 100° in the retrograde direction and 1.5 au away from the Sun, the radiation detector on board the Curiosity surface rover observed the largest ground-level …

The main driver of the acceleration of solar energetic particles (SEPs) is believed to be shocks driven by coronal mass ejections. Extreme-ultraviolet (EUV) waves are thought to be the propagating footprint of the shock on the solar surface. One of the key questions in SEP research is the timing of the SEP release with respect to the time when the EUV wave magnetically connects with an observer. Taking advantage of close-to-the-Sun measurements by Parker Solar Probe (PSP) and Solar Orbiter (SolO), we investigate an SEP event that occurred on 2021 September 28 and was observed at different locations by SolO, …

Modeling Archaic Land Use And Mobility In North-Central Belize, Marieka Brouwer Burg, Eleanor Harrison-Buck Feb 2024

Modeling Archaic Land Use And Mobility In North-Central Belize, Marieka Brouwer Burg, Eleanor Harrison-Buck

Faculty Publications

The Archaic period has not been as widely studied in Mesoamerica as it has been in other parts of the Americas. This problem stems from intractable issues such as low archaeological visibility and high post-depositional disturbance. And, while existing Archaic data from northern Belize indicates that foraging groups practiced diverse adaptations, little theoretical effort has been dedicated toward developing frames of reference for understanding the coupled human-landscape interactions ongoing during this period. Here, we outline a multi-method approach for situating hunter-gatherer-fisher-emergent horticultural land use behaviors, including comparative ethnographic data, extant archaeological information, and geospatial modeling. We set out a series …

Faculty Publications

River networks play a crucial role in the global carbon cycle, as relevant sources of carbon dioxide (CO2) to the atmosphere. Advancements in high-frequency monitoring in aquatic environments have enabled measurement of dissolved CO2 concentration at temporal resolutions essential for studying carbon variability and evasion from these dynamic ecosystems. Here, we describe the adaptation, deployment, and validation of an open-source and relatively low-cost in situ pCO2 sensor system for lotic ecosystems, the lotic-SIPCO2. We tested the lotic-SIPCO2 in 10 streams that spanned a range of land cover and basin size. Key system adaptations for lotic environments included prevention of biofouling, …

Observational Features Of Charge Distribution In Earth's Inner Magnetosphere, Lai Gao, Chao Shen, Yufei Zhou, Yong Ji, Zuyin Pu, George Parks, Christopher T. Russell, Gang Zeng, Lan Ma, Roy B. Torbert, Yanyan Yang, James L. Burch Feb 2024

Observational Features Of Charge Distribution In Earth's Inner Magnetosphere, Lai Gao, Chao Shen, Yufei Zhou, Yong Ji, Zuyin Pu, George Parks, Christopher T. Russell, Gang Zeng, Lan Ma, Roy B. Torbert, Yanyan Yang, James L. Burch

Faculty Publications

Understanding the motion of charged particles in the electromagnetic field in the inner magnetosphere is essential for space science and space weather. Charge accumulation can occur due to the dipole magnetic and convective electric fields in this region. However, until the recent Magnetospheric Multiscale (MMS) mission, there were few means to detect charge distribution in situ. We report unambiguous in situ observation of the spatial distribution of the excess charge density in the inner magnetosphere by the MMS mission. We find that a positive (negative) charge accumulates in the dusk (dawn) side inner magnetospheres, which is contrary to the long …

Biden, Trump Running Away With Primary Races In Vermont 2/22/2024, Unh Survey Center Feb 2024

Biden, Trump Running Away With Primary Races In Vermont 2/22/2024, Unh Survey Center

All UNH Survey Center Polls

Less than two weeks away from the primary on Super Tuesday, former President Donald Trump holds a 30 percentage point lead over former U.N. Ambassador Nikki Haley among likely Republican Primary voters in Vermont. President Joe Biden holds an even larger lead over Minnesota Representative Dean Phillips, though relatively few Democratic primary voters would be enthusiastic if Biden is the party's nominee. Vermonters rate Biden more highly than Trump on several characteristics. Biden's biggest strengths according to Vermont residents are his honesty, integrity, and temperament, though many rate his mental and physical fitness poorly.


What Diameter? What Height? Influence Of Measures Of Average Tree Size On Area-Based Allometric Volume Relationships, Yilin Wang, John A. Kershaw, Mark J. Ducey, Yuan Sun, James B. Mccarter Feb 2024

What Diameter? What Height? Influence Of Measures Of Average Tree Size On Area-Based Allometric Volume Relationships, Yilin Wang, John A. Kershaw, Mark J. Ducey, Yuan Sun, James B. Mccarter

Faculty Publications

Volume is an important attribute used in many forest management decisions. Data from 83 fixed-area plots located in central New Brunswick, Canada, are used to examine how different measures of stand-level diameter and height influence volume prediction using a stand-level variant of Honer's (1967) volume equation. When density was included in the models (Volume=f(Diameter,Height,Density)) choice of diameter measure was more important than choice of height measure. When density was not included (Volume=f(Diameter,Height)), the opposite was true. For models with density included, moment-based estimators of stand diameter and height performed better than all other measures. For models without density, largest tree …

Biden, Trump Dominate Maine Primaries 2/22/2024, Unh Survey Center

All UNH Survey Center Polls

The 2024 Maine Presidential Primary is less than two weeks away and more than three-quarters of likely Republican primary voters support former President Donald Trump. President Joe Biden holds an even larger lead on the Democratic side, but likely Democratic voters are less enthusiastic about him becoming the party's nominee. When asked to rate several characteristics of Biden and Trump, majorities rate Biden's temperament, honesty, and integrity more highly than Trump's, but a plurality believe Trump has better mental and physical stamina.
