Utilization of the Child Opportunity Index to Evaluate Timing of Tympanostomy Tube Placement

Otolaryngology–Head and Neck Surgery, Volume 174, Issue 2, Page 547-553, February 2026.
Abstract Objective Socioeconomic factors including social determinants of health (SDOH) have been implicated in tympanostomy tube (TT) placement and otorrhea. The objective of this study was to determine whether SDOH play a role in delays from presentation to TT placement. Study Design Retrospective cohort study. Setting Tertiary Care Center. Methods A

Improving Geoidal Height Estimates from Global Geopotential Model Using Regression Model and GPS Data [PDF]

, 1997
Conventionally, for most application, position of a point is often referred to the geoid as the reference surface. Thus there is an important need for the knowledge of the geoid undulation in the area where positioning tasks is performed, This ...

Lithospheric Delamination Below the North American Midcontinent Ceased Subsidence in Cratonic Basins

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Cratonic lithospheres carry a long history of tectonic modifications that result in heterogeneous structures, as revealed by an increasing number of geophysical observations. The existence of cratonic basins indicates protracted periods of tectonic modification, causing subsidence within global continental interiors.

Geoid model determination for the Hellenic area “Hellas Geoid 2023”

Acta Geodaetica et Geophysica, 2023
AbstractThe latest geoid model "HELLAS GEOID 2023" (HG2023) derived by the Hellenic Military Geographical Service is the most comprehensive model for the entire Hellenic area. Long-term gravity data, orthometric and geometric heights, seabed topography and a high-resolution digital terrain model were implemented in the calculations. Data evaluation and

Modeling Geoid and Dynamic Topography From Tomography‐Based Thermo‐Chemical Mantle Convection

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Mantle convection causes the most important contribution to the geoid and dynamic topography. With mantle density inferred from high‐resolution tomography models and numerical methods solving the governing equations of viscous mantle flow, the modeled geoid can fit the observations well.

Evaluating SWOT in the Coastal Zone: Comparisons With Tide Gauge and Airborne LiDAR in the Bristol Channel and Severn Estuary, UK

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Traditional nadir altimeters struggle with coastal water surface elevation (WSE) measurement and fine‐scale river‐estuary interactions, due to land‐water signal interference and their wide inter‐track spacing. The wide‐swath Surface Water and Ocean Topography (SWOT) mission, using a new Ka‐band radar interferometer, aims to address these ...

The Influence of Bathymetry on Regional Marine Geoid Modeling in Northern Europe

Journal of Marine Science and Engineering, 2022
Although Northern Europe has been the target area in many regionwide geoid determination studies, the research has been land-focused, neglecting bathymetry information. With new projects, such as the Baltic Sea Chart Datum 2000, the attention is shifting

Spaceborne Canopy Height Products Should Be Complemented With Airborne Laser Scanning Data: Toward a European Canopy Height Model

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Measuring and mapping vegetation structure is essential for understanding the functioning of terrestrial ecosystems and for informing environmental policies. Recent years have seen a growing demand for high‐resolution data on vegetation structure, driving their prediction at fine resolutions (1–30 m) at state, continental, and global spatial ...

Distribution Models Reveal Important Coastal Habitats for Endangered Leatherback Sea Turtles

Diversity and Distributions, Volume 32, Issue 1, January 2026.
ABSTRACT Aim With the development and operation of offshore wind farms along the United States East Coast, it is imperative that we understand the distributions of vulnerable species so we can track and predict potential interactions. We focused on leatherback sea turtles (Dermochelys coriacea) as they depend on this region for important stages of ...

Unveiling the Floodplain River‐Lake Hydrological Interactions by SWOT Observations

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract The bidirectional exchange between rivers and floodplain lakes is critical for regional hydrology, nutrient cycling, and ecosystem management. However, observing the two‐dimensional water surface elevation (WSE) fields that govern these interactions remains a long‐standing challenge, limiting understanding of hydraulic regime shifts.
