Water Vapor Vertical Distribution on Mars After Six Years of TGO/NOMAD Solar Occultations: 1. Global Climatology

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract We present vertical profiles of water vapor obtained during six continuous years of solar occultation observations in the infrared by the Nadir and Occultation for MArs Discovery (NOMAD) instrument on board Trace Gas Orbiter. The retrievals have been performed with an inversion code previously applied to smaller samples of this data set, but ...

Water Vapor Vertical Distribution on Mars After Six Years of TGO/NOMAD Solar Occultations: 2. Cross‐Validation Within TGO and Comparison With MPCM

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract This is the second part of an investigation of water vapor in the Martian atmosphere using solar occultation observations by the Nadir and Occultation for MArs Discovery (NOMAD) spectrometer on board the ExoMars Trace Gas Orbiter. Following the analysis of six Earth years of NOMAD observations performed in the first part, a cross‐validation ...

An arbuscular mycorrhiza from the 407‐million‐year‐old Windyfield Chert identified through advanced fluorescence and Raman imaging

New Phytologist, Volume 249, Issue 1, Page 448-459, January 2026.
Summary Mycorrhizal associations between fungi and plants are a fundamental aspect of terrestrial ecosystems. Mycorrhizas occur in c. 85% of extant plants, yet their geological record remains sparse. Rare fossil evidence from early terrestrial environments offers crucial insights into these ancient symbioses, but visualizing fossil fungi at the ...

The Manufacture of Rochia nilotica rings: The chaîne opératoire Identified for Lapita Sites in Vanuatu

Archaeology in Oceania, Volume 60, Issue 3, Page 201-219, October 2025.
ABSTRACT Rings made on marine shell are a conspicuous artefact form found throughout cultural sequences for much of the Pacific over millennia. Despite their importance in both recent and ancient times, in‐depth consideration of the manufacturing processes involved in shell ring production are limited.

The coronal line regions of planetary nebulae NGC 6302 and 6537: 3-13 mu m grating and echelle spectroscopy [PDF]

, 2000
We report on advances in the study of the cores of NGC 6302 and 6537 using infrared grating and echelle spectroscopy. In NGC 6302, emission lines from species spanning a large range of ionization potential, and in particular [Si IX] 3.934 μm, are ...

Unexpected pathway for intercontinental movement into the Nearctic revealed by phylogenetic analyses

Zoologica Scripta, Volume 54, Issue 4, Page 562-574, July 2025.
Abstract Much of North America's freshwater biodiversity is derived from Palearctic lineages. Isopods of the Holarctic family Asellidae are among the most widespread and diverse freshwater crustaceans, but Nearctic species are poorly studied. We examined the evolutionary history of the family, utilizing Sanger sequencing of mitochondrial and nuclear ...

Inter‐Model Variability of Tropical Total Ice Water Path Simulated by the Convection Permitting DYAMOND Models

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 9, 16 May 2025.
Abstract Cirrus clouds have a large impact on radiation, yet coarse resolution models struggle to simulate their properties and structure realistically. Employing globally resolutions of below 5 km, the models from the Dynamics of the Atmospheric general circulation Modeled On Non‐hydrostatic Domains (DYAMOND) project do not require a parameterization ...

Relationships Between Aquatic Ecology, Landscapes, Hydrogeology and Hydrochemistry in Great Basin and Mojave Desert Spring Systems USA

Ecohydrology, Volume 18, Issue 3, April‐May 2025.
ABSTRACT Springs are groundwater‐dependent systems sustaining most of the riparian and aquatic habitat in western North America's deserts. The relationship between hydrogeology and springs is recognized by groundwater hydrologists and ecologists; however, studies integrating these disciplines have focused on site and species‐specific relationships.

Experimental demonstration of a cross-order echelle grating triplexer based on an amorphous silicon nanowire platform

, 2009
We present the design, fabrication, and characterization of an ultracompact silicon-on-insulator-based echelle grating triplexer. It is based on the cross-order design, which utilizes different diffraction orders to cover a large spectral range from 1.3 ...
