Is It Hot Here? How Increased Water Temperature Impacts Tunicates On A Physiological Level, Melanie Burley

Inquiry Journal Spring 2024

When you think of marine species that live in the Gulf of Maine, a tiny invertebrate attached to the side of a dock may not be the first one that comes to mind. However, tunicates have a powerful influence on other species within their environment. This is especially true in the Gulf of Maine, where they have been found on the side of boat docks, tangled up on lobster traps, and attached to oyster and mussel beds.

Increasing amounts of certain invasive species of tunicates can negatively impact the organisms around them. Tunicates can have a drastic impact on local …

Quantifying the temperature sensitivity of methane (CH4) production is crucial for predicting how wetland ecosystems will respond to climate warming. Typically, the temperature sensitivity (often quantified as a Q10 value) is derived from laboratory incubation studies and then used in biogeochemical models. However, studies report wide variation in incubation-inferred Q10 values, with a large portion of this variation remaining unexplained. Here we applied observations in a thawing permafrost peatland (Stordalen Mire) and a well-tested process-rich model (ecosys) to interpret incubation observations and investigate controls on inferred CH4 production temperature sensitivity. We developed a field-storage-incubation modeling approach to mimic the full …

Coronal holes are recognized as the primary sources of heliospheric open magnetic flux (OMF). However, a noticeable gap exists between in situ measured OMF and that derived from remote-sensing observations of the Sun. In this study, we investigate the OMF evolution and its connection to solar structures throughout 2014, with special emphasis on the period from September to October, where a sudden and significant OMF increase was reported. By deriving the OMF evolution at 1 au, modeling it at the source surface, and analyzing solar photospheric data, we provide a comprehensive analysis of the observed phenomenon. First, we establish a …

Universal Design For Learning (Udl)- Strategies For Engaging Rural Youth Co-Researchers With Informal Stem Learning, Amanda Bastoni, Jayson Seaman, Andrew D. Coppens, Cindy Hartman, Kate Moscouver, Courtnie Lachaine

Faculty Publications

This article describes methods and findings from a study focused on youth living in rural communities in northern New Hampshire who struggle with accessing STEM learning opportunities for reasons including economic underinvestment and geographical isolation. These challenges also negatively impact researchers hoping to learn how rural youth benefit from informal STEM learning experiences, which contribute to low-project participation and retention rates. As in other amenity-rich rural areas, the communities in this study are promoting outdoor recreation as a vehicle for economic development. We wanted to understand if outdoor recreation activities tied to economic growth initiatives — activities which youth have …

Reliable Identification Of Binary Supermassive Black Holes From Rubin Observatory Time-Domain Monitoring, Megan C. Davis, Kaylee E. Grace, Jonathan R. Trump, Jessie C. Runnoe, Amelia Henkel, Laura Blecha, W N. Brandt, J Andrew Casey-Clyde, Maria Charisi, Caitlin A. Witt

Faculty Publications

Periodic signatures in time-domain observations of quasars have been used to search for binary supermassive black holes (SMBHs). These searches, across existing time-domain surveys, have produced several hundred candidates. The general stochastic variability of quasars, however, can masquerade as a false-positive periodic signal, especially when monitoring cadence and duration are limited. In this work, we predict the detectability of binary SMBHs in the upcoming Rubin Observatory Legacy Survey of Space and Time (LSST). We apply computationally inexpensive sinusoidal curve fits to millions of simulated LSST Deep Drilling Field light curves of both single, isolated quasars and binary quasars. The period …

Parker Solar Probe (PSP) observations of a small dispersive event on 2022 February 27 and 28 indicate scatter-free propagation as the dominant transport mechanism between the low corona and greater than 35 solar radii. The event occurred during unique orbital conditions that prevailed along specific flux tubes that PSP encountered repeatedly between 25 and 35 Rs during outbound orbit 11. This segment of the PSP orbit exhibits almost stationary angular motion relative to the rotating solar surface, such that in the rotating frame, PSP’s motion is essentially radial. The time dispersion often observed in impulsive solar energetic particle (SEP) events …

Factors Affecting Iodine Content Of Cow Milk-A Review, Mmh Khandakar, Ma Islam

Faculty Publications

This review discusses the importance of iodine as an essential nutrient for human health and the factors that can influence the concentration of iodine in cow milk. For an adult, the daily recommended requirement of iodine is 150 µg/day and the maximum tolerable limit ranges from 600 to 1100 µg/day. Cow milk is a significant source of iodine in many countries, particularly in areas where iodine-rich foods are not readily available. Therefore, evaluating the variables that affect the iodine content of cow milk is important. The iodine concentration of cow milk can vary depending on several factors such as genetics, …

Size Limits And Fission Channels Of Doubly Charged Noble Gas Clusters, Ianessa Stromberg, Stefan Bergmeister, Lisa Ganner, Fabio Zappa, Paul Scheier, Olof Echt, Elisabeth Gruber

Faculty Publications

Small, highly charged liquid droplets are unstable with respect to spontaneous charge separation when their size drops below the Rayleigh limit or, in other words, their fissility parameter X exceeds the value 1. The absence of small doubly charged atomic cluster ions in mass spectra below an element-specific appearance size n_a has sometimes been attributed to the onset of barrierless fission at X = 1. However, more realistic models suggest that n_a marks the size below which the rate of fission surpasses that of competing dissociative channels, and the Rayleigh limit of doubly charged van der Waals clusters …

Influence Of Climate Zone Shifts On Forest Ecosystems In Northeastern United States And Maritime Canada, Samuel Roy, Xinyuan Wei, Aaron Weiskittel, Daniel J. Hayes, Peter Nelson, Alexandra R. Contosta

Faculty Publications

Climate zones play a significant role in shaping the forest ecosystems located within them by influencing multiple ecological processes, including growth, disturbances, and species interactions. Therefore, delineation of current and future climate zones is essential to establish a framework for understanding and predicting shifts in forest ecosystems. In this study, we developed and applied an efficient approach to delineate regional climate zones in the northeastern United States and maritime Canada, aiming to characterize potential shifts in climate zones and discuss associated changes in forest ecosystems. The approach comprised five steps: climate data dimensionality reduction, sampling scenario design, cluster generation, climate …

Science Opportunities For Imap-Lo Observations Of Interstellar Neutral Hydrogen And Deuterium During A Maximum Of Solar Activity, M A. Kubiak, M Bzowski, E Möbius, Nathan A. Schwadron

Faculty Publications

Direct-sampling observations of interstellar neutral gas, including hydrogen and deuterium, have been performed for more than one cycle of solar activity by IBEX. The IBEX viewing is restricted to directions perpendicular to the spacecraft–Sun line, which limits the observations to several months each year. This restriction is removed in the forthcoming mission called Interstellar Mapping and Acceleration Probe. The IMAP-Lo instrument will have the capability of adjusting the angle of its boresight with the spacecraft rotation axis. We continue a series of studies of the resulting science opportunities. We adopt the schedule of adjusting the boresight angle suggested by Kubiak …

Salt Marsh Migration Into Coastal Uplands And Application For Conservation In New Hampshire, Grant Mckown, David Burdick

Jackson Estuarine Laboratory

Salt marshes across the East Coast, including New Hampshire, have lost considerable areas of vegetation cover from shoreline erosion and interior pool formation as sea level rise outpaces the marsh’s ability to maintain elevation. Marsh migration, or the inland transgression of halophyte vegetation into upland habitats, is one of the main mechanisms for salt marshes to maintain their areal extent on centennial timescales and recently has been a key strategy discussed by resource managers for shorter term timescales. A literature review was conducted to determine the extent of the research on the topic including biogeochemical drivers, response of the vegetation …

Cummings, J R. Szalay, C M S Cohen, Nathan A. Schwadron, R Chhiber, F Pecora, W H. Matthaeus, R A. Leske, M L. Stevens

Faculty Publications

Solar energetic particle (SEP) events have been observed by the Parker Solar Probe (PSP) spacecraft since its launch in 2018. These events include sources from solar flares and coronal mass ejections (CMEs). The IS⊙IS instrument suite on board PSP is measuring ions over energies from ∼ 20 keV nucleon−1 to 200 MeV nucleon−1 and electrons from ∼ 20 keV to 6 MeV. Previous studies sought to group CME characteristics based on their plasma conditions and arrived at general descriptions with large statistical errors, leaving open questions on how to properly group CMEs based solely on their plasma conditions. To help …

The Gyrokinetic Dispersion Relation Of Microtearing Modes In Collisionless Toroidal Plasmas, Benjamin D G Chandran, A A. Schekochihin

Faculty Publications

We solve the linearized gyrokinetic equation, quasineutrality condition and Ampere's law to obtain the dispersion relation of microtearing modes (MTMs) in collisionless low- $\beta$ toroidal plasmas. Consistent with past studies, we find that MTMs are driven unstable by the electron temperature gradient and that this instability drive is mediated by magnetic drifts. The dispersion relation that we derive can be evaluated numerically very quickly and may prove useful for devising strategies to mitigate MTM instability in fusion devices.
