title: “Elastic Universe Theory: Core Appendices on EFT Equivalence, Higher-Order Operators, and Physical Applications”

description: This document presents the core appendices of the Elastic Universe Theory (EUT), a unified physical framework in which spacetime, matter, and all fundamental interactions emerge from the elastic dynamics of a continuous vacuum field η(x,t).The EFT Equivalence Theorem demonstrates that any local, Lorentz-invariant, unitary, and SU(4)-gauge-invariant field theory with a stabilizing potential is mathematically reducible, at low energy, to the canonical EUT Lagrangian.This Lagrangian uniquely integrates gauge dynamics (strong, weak, and electromagnetic), the elastic-metric formulation of gravity, and a Landau-type synchronization term responsible for global temporal coherence.<br>Appendix B introduces higher-order operators (dimensions 6 and 8) describing nonlinear corrections relevant at extreme curvature or quantum-gravitational regimes, while Appendix C outlines physical applications connecting the three core parameters of the theory—elastic modulus K, mean strain ε, and natural frequency ω₀—to observable phenomena such as matter formation, elastic gravitation, and quantized oscillons.<br>The results confirm that gravitation, particle masses, and cosmic expansion are not independent sectors but coherent elastic modes of the same vacuum continuum.The work formalizes the theoretical completeness of the EUT as the unique effective field theory compatible with SU(4) symmetry and vacuum stability.

title: Assessing the Distribution and Variability of Marine Mammals through Archaeology, Ancient DNA, and History in the North Atlantic (1960-2024)

description: The North Atlantic Marine Mammal Project uses the transdisciplinary tools of history, saga studies, archaeology, ancient DNA (aDNA), and marine mammalogy to reconstruct economic contributions of cetaceans and pinnipeds across premodern Iceland and Orkney, ca. 800 – 1500 CE. Using aDNA and Zoo Archaeology by Mass Spectrometry (ZooMS) analysis, over 295 specimens, comprising 15 species have been identified from archaeological sites in northern Iceland, Orkney, and the Faroe Islands. Species identified include blue, right, and gray whales, species whose populations were devastated by industrial whaling.

title: NOAA/WDS Paleoclimatology - Mt. Logan - 7,400 Year Glaciochemical Data

description: A high-resolution, 8000 year-long ice core record from the Mt. Logan summit plateau (5300 m asl) reveals the initiation of trans-Pacific lead (Pb) pollution by ca. 1730, and a >10-fold increase in Pb concentration (1981–1998 mean = 68.9 ng/l) above natural background (5.6 ng/l) attributed to rising anthropogenic Pb emissions from Asia. The largest rise in North Pacific Pb pollution from 1970–1998 (end of record) is contemporaneous with a decrease in Eurasian and North American Pb pollution as documented in ice core records from Greenland, Devon Island, and the European Alps. The distinct Pb pollution history in the North Pacific is interpreted to result from the later industrialization and less stringent abatement measures in Asia compared to North America and Eurasia. The Mt. Logan record shows evidence for both a rising Pb emissions signal from Asia and a trans-Pacific transport efficiency signal related to the strength of the Aleutian Low.

title: NOAA/WDS Paleoclimatology - ACT2 - Toxic Heavy Metals Data

description: Toxic heavy metals emitted by industrial activities in the midlatitudes are transported through the atmosphere and deposited in the polar regions; bioconcentration and biomagnification in the food chain mean that even low levels of atmospheric deposition may threaten human health and Arctic ecosystems. Little is known about sources and long-term trends of most heavy metals before ≈1980, when modern measurements began, although heavy-metal pollution in the Arctic was widespread during recent decades. Lacking detailed, long-term measurements until now, ecologists, health researchers, and policy makers generally have assumed that contamination was highest during the 1960s and 1970s peak of industrial activity in North America and Europe. We present continuous 1772–2003 monthly and annually averaged deposition records for highly toxic thallium, cadmium, and lead from a Greenland ice core showing that atmospheric deposition was much higher than expected in the early 20th century, with tenfold increases from preindustrial levels by the early 1900s that were two to five times higher than during recent decades. Tracer measurements indicate that coal burning in North America and Europe was the likely source of these metals in the Arctic after 1860. Although these results show that heavy-metal pollution in the North Atlantic sector of the Arctic is substantially lower today than a century ago, contamination of other sectors may be increasing because of the rapid coal-driven growth of Asian economies.

title: NOAA/WDS Paleoclimatology - Southern Ocean Carbon and Nitrogen Isotopic Ratios

description: Oceanic nutrient cycling in the Southern Ocean is supposed to have an important impact on glacial-interglacial atmospheric CO2 changes and global climate. In order to characterize such nutrient cycling over the last two climatic cycles, we investigated carbon and nitrogen isotopic ratios of diatom-bound organic matter (d13Cdiat and d15Ndiat respectively) in two cores retrieved form the Atlantic and Indian sectors of the Antarctic Ocean. The two cores show the same isotopic patterns. d13Cdiat values are depleted during glacial periods and enriched during interglacial periods indicating lower productivity during cold times. d15Ndiat values are enriched during glacial periods and depleted during interglacial periods arguing for greater nitrate utilization during cold times. Taken at face value, this apparent contradiction leads to opposite conclusions on the role of the Southern Ocean biological pump on the atmospheric CO2 changes. But, the two sets of data can be reconciled by a ""sea ice + mixing rate scenario"" that calls upon a balance between the effect of cutting off gas transfer at the ocean-atmosphere boundary and the effect of reducing vertical transport of nutrients through the pycnocline.
