The perplexing patches of light-colored ocean are sometimes noticed in other oceans and lakes worldwide, but in the Bahamas, they pop up more often than usual. Direct sampling of the cloudy waters suggests they contain high concentrations of carbonate-rich particles. Much of the Bahama archipelago sits on a submerged platform of carbonate known as the ...

Chesapeake Conservancy’s data science team developed an artificial intelligence deep learning model for mapping wetlands, which resulted in 94% accuracy.

Un team di ricercatori dell’ENEA ha sviluppato un nuovo approccio per prevedere l’area di propagazione e l’intensità delle colate rapide, un particolare tipo di frane veloci altamente distruttivo, e sta testando nuove metodologie per stimarne le soglie di innesco in base al contenuto di acqua dei terreni di copertura. Le innovazioni volte al la produzione ...

Years of research show that climate change signals are amplified in the Arctic, and that sea ice in this region is sensitive to increases in Arctic warming. Sea ice greatly modifies the exchanges of heat, momentum and mass between the atmosphere and the ocean. So, the timings of the sea ice melt and freeze onsets, ...

El Servicio Nacional de Meteorología e Hidrología del Perú (Senamhi) anunció el lanzamiento de Senamhi GEOGloWS, una plataforma que cuenta con tecnología de la Administración Nacional de Aeronáutica y del Espacio (NASA).

In an article published in the journal Remote Sensing, the researchers used Sentinel-2/Multispectral Instrument (MSI) imagery data to a calibrated ocean chlorophyll 2-band (OC-2) model to retrieve chlorophyll-a (chl-a) concentration in the Ha Long bay from 2019 to 2021. Using Sentinel-2 MSI photos on the Google Earth Engine (GEE) platform, this study examines the anthropogenic ...

Avast network of waterways lies hidden under Naples, Italy, including aqueducts that were built when the ancient Greeks colonized the area. “They are waterways or aqueducts that were constructed during that period and also during Roman times,” says Nick De Pace. “There are also streams and other waterways that were developed over time to guide ...

If global warming persists, blue lakes worldwide are at risk of turning green-brown, according to a new study which presents the first global inventory of lake color. Shifts in lake water color can indicate a loss of ecosystem health. While substances such as algae and sediments can affect the color of lakes, the new study ...

Altering streamflow can endanger the ecosystems that rely on it, but researchers have lacked data on how human infrastructure has impacted streamflow in the U.S. Now, a study involving a Colorado State University researcher has mapped streamflow alterations across the continental U.S., providing a wealth of data for determining societal impacts on ecosystems. Up to ...
