Short‐Term Estuarine Phytoplankton Dynamics in Response to Hurricanes Along the Gulf Coast of America: A Variational Autoencoder (VAE) Approach With Satellite and Bio‐Optical Observations

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Hurricanes drive diverse estuarine phytoplankton responses and can trigger cascading ecological and physicochemical impacts. Capturing these short‐term dynamics requires high spatiotemporal resolution. Here, we applied a globally‐applicable coastal ocean color algorithm, Variational Autoencoder (VAE), to Sentinel‐2 MSI imagery for chlorophyll ...

Double‐Peaked Hyperspectral Features at 710 and 800 nm for Monitoring Coastal Chlorophyll‐α Concentrations From Space

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract The concentration of chlorophyll‐α $\alpha $ has been estimated from sea color, primarily based on the reflectance ratio between the blue and green spectral bands in multiband images obtained by satellite optical sensors. However, this method is only effective in open, clear water and cannot be reliably applied to shallow coastal waters.

Monitoring Flood Inundation Dynamics From Space

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract With the increasing intensity and frequency of flood events worldwide, the need for accurate and timely inundation mapping has never been more critical. Large‐scale flood extent estimations are vital for coordinating effective disaster response, facilitating recovery, and building future resilience.

Snow and ice broadband albedo from Sentinel-3 OLCI measurements and empirical regression

, 2021
This dataset contains: snow and ice broadband albedo mosaics over Greenland for years 2018 and 2019 computed from a simple empirical approach (Wehrlé et al, 2021). This approach consists of a fit between 4729 hourly PROMICE albedo measurements and

Empirical model for chlorophyll-a determination in inland waters from the forthcoming Sentinel-2 and 3. Validation from HICO images

Revista de Teledetección, 2014
Chlorophyll-a concentration is one of the main indicators of inland waters quality. Using CHRIS/PROBA images and in situ data obtained in four lakes in Colombia and Spain, we obtained empirical models for the estimation of chlorophyll-a concentration ...

Satellite‐Driven Synthesis of Fish Production Dynamics and Carrying Capacity Mechanisms in a High‐Altitude Lake Ecosystem

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This study evaluates fish potential production (FPP) and fish carrying capacity index (FCCI) in Qinghai Lake using satellite‐based primary production estimates. Results show increasing FPP trends and spatially heterogeneous FCCI, indicating potential for sustainable fisheries management and guiding restocking efforts in this high‐altitude lake ...

Novel Insights on Ocean Internal Waves: Quantitative Surface Manifestations and Upper Ocean Layer Displacements From the Surface Water Ocean Topography Mission (SWOT) Measurements

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission provides unprecedented high‐resolution simultaneous observations of both sea surface height anomalies and sea surface roughness. Specifically, it enables more precise analysis of strong internal waves. Off the Amazon Shelf, in the Indonesian Seas, and near the Mascarene Ridge, internal wave

Using Optical Water Types to Monitor Changes in Optically Complex Inland and Coastal Waters

Remote Sensing, 2019
The European Space Agency’s Copernicus satellites Sentinel-2 and Sentinel-3 provide observations with high spectral, spatial, and temporal resolution which can be used to monitor inland and coastal waters. Such waters are optically complex, and the

From Standard to Bayesian: Revisiting Ocean Color Model Evaluation

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Ocean color models, facilitated by satellite‐based remote sensing technologies, have transformed our ability to monitor chlorophyll‐a concentrations at the ocean's surface. These models decode changes in the spectral properties of reflected sunlight to map phytoplankton biomass across extensive spatial and temporal scales.
