Hydrological Cycle Intensification and Permafrost Thaw Drive Increased Freshwater and Organic Carbon Inputs to Northern Alaska Estuaries

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Understanding how hydrological inflows and climate change influence individual estuaries across northern Alaska is limited by a paucity of measured data, necessitating the application of suitably scaled numerical process models. This study uses an updated model to quantify freshwater discharge and dissolved organic carbon (DOC) export from the

Larsen C Ice Shelf in the Western Weddell Sea is a Hotspot for Export Production in the Antarctic Ocean

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract The Southern Ocean accounts for >30% of the global ocean CO2 sink as a result of its solubility and biological pumps. To investigate the biological pump near Larsen C Ice Shelf (LCIS) in the Southern Ocean's western Weddell Sea, we measured the concentrations and nitrogen isotope ratios of nitrate, ammonium, and particulate organic nitrogen ...

Multiscale Bayes Adaptive Threshold Wavelet Transform Geomagnetic Basemap Denoising Taking Residual Constraints into Account

Sensors
To achieve high-precision geomagnetic matching navigation, a reliable geomagnetic anomaly basemap is essential. However, the accuracy of the geomagnetic anomaly basemap is often compromised by noise data that are inherent in the process of data ...

Development of a Mesoscale‐ and Tide‐Resolving Ocean–Biogeochemistry Model for the Pacific: Tidal Enhancement of the Biological Carbon Pump

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract This study presents a new physical‐biogeochemical simulation of the Pacific Ocean that resolves mesoscale dynamics and explicitly includes tidal forcing. The primary objective is to develop and document a modeling framework that serves both as a detailed record of model configuration and forcing preparation, and as a reference for future ...

An integrated novel approach to the environmental health assessment of Bangladesh's coastal ecosystems

Environmental Challenges
The coastal expanse of Bangladesh, situated along the Bay of Bengal, is a susceptible and low-lying area grappling with multiple environmental challenges. Various physicochemical parameters were employed in the assessment of water quality. The CCME Water
