Geologic Reconnaissance in Baja California [PDF]
The Journal of Geology, 1921 During 1921, I spent several months in Baja California determining geologic relations of a large area, and as there is but little on record regarding the geology of this region, it is desirable to set forth such of my observations as appear to be of general interest.

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.Abstract Proxy records of seawater radiocarbon (14C/C) provide strong constraints on how changes in ocean ventilation contributed to the increase in atmospheric CO2 during the termination of the last ice age (≈18,000‐to‐12,000 years ago). One outstanding problem, however, is the existence of anomalously low deglacial benthic foraminiferal 14C/C in the ...

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.Abstract Climate change is currently driving the expansion of oxygen minimum zones (OMZs), areas of the open ocean with consistently low oxygen levels. Changes in temperature, productivity and consequent respiration, and water mass ventilation drive OMZ expansion and contraction with implications for ecosystem function and biogeochemical cycling ...

Supply Chain Management in Renewable Energy Projects from a Life Cycle Perspective: A Review
Applied SciencesThe growing demand for renewable energy positions it as a cornerstone for climate change mitigation and greenhouse gas emissions reduction. Although renewable energy sources generate around 30% of global electricity, their production and deployment ...

Biomass and reproduction of Pacific sardine (Sardinops sagax) off the Pacific northwestern United States, 2003–2005 [PDF]
, 2010 The Pacific sardine (Sardinops sagax) is distributed along the west coast of North America from Baja California to British Columbia. This article presents estimates of biomass, spawning biomass, and related biological parameters based on four trawl ...

Alimentary Pharmacology &Therapeutics, Volume 63, Issue 10, Page 1390-1397, May 2026.Nationwide implementation of double reflex testing for hepatitis delta in Spain markedly increased anti‐HDV and HDV viral load testing between 2022 and 2024, enabling national seroprevalence estimates. Despite this progress, substantial regional heterogeneity persists, highlighting the need for standardised reflex diagnostic protocols.

Acmaeodera pubiventris Horn (Coleoptera: Buprestidae) : a polytypic species or a superspecies? [PDF]
, 1999 Acmaeodera pubiventris Horn was studied in detail and, without rejecting that it may be a superspecies, I concluded it is a polytypic species comprised of A. p. pubiventris, A. p. lanata Horn, A. p.

Baja California Sur map underway
Eos, Transactions American Geophysical Union, 1992 Through a cooperative effort by geophysicists interested in the geology of Baja California, a map of the southern state of the peninsula will be compiled and published in three sheets at a scale of 1:250,000.At the April 1991 First International Meeting on the Geology of the Baja California Peninsula, held at the Universidad Autonoma de Baja California

High‐Resolution Observations Unveil (Sub)Mesoscale Heat Fluxes Shaping Upper‐Ocean Heat Content
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Upper‐ocean heat content (UOHC) modulates air–sea exchange in tropical regions; however, its variability at (sub)mesoscale remains insufficiently resolved. Here we combine Surface Water and Ocean Topography (SWOT) observations with high‐resolution glider sections in the northeastern tropical Pacific, where mesoscale eddies and sharp frontal ...

Dynamically‐Informed Extreme Event Attribution Using Circulation Imprints
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract We present a novel extreme event attribution approach, isolating dynamical from other contributions to changing extreme event probability. Event‐specific, multivariate circulation imprints are linked to impact‐relevant hazard indices in a flexible framework which we demonstrate for three recent high‐impact extreme events: the 2025 Los Angeles ...
