Seagrasses are among the most important foundation species in coastal ecosystems, providing habitat for marine life, stabilizing sediments and helping improve water quality.

Harmful algal blooms (HABs) have become an increasingly common threat to lakes, rivers and coastal waters across the United States, endangering drinking water supplies, aquatic ecosystems, public health and local economies.

A new study analyzed data from multiple independent sources, ranging from satellite remote sensing-based machine learning products to state-of-the-art Earth System Models, to reveal how climate change shapes the Northern Eurasian carbon sink. 

Arctic terrestrial permafrost ecosystems store around 1,300 gigatonnes of carbon from organic sources, such as from the remains of plants. Sediments in oceans and river deltas contain a further 400 gigatonnes.

Since the first major bleaching event in 1996, Hawaiian corals have been subject to increasing heat stress and more prevalent bleaching events.

Before being patched with thick black asphalt during recent weeks, the roads across Goldstream Creek’s swampy valley bucked my car like a whitewater raft in the Nenana River canyon.

Streams are abruptly acidifying and turning orange or milky-white across vast regions of North America’s northwest.

Human activities are fundamentally altering the chemical makeup of local coral reefs, according to a study led by the University of Hawaiʻi at Mānoa and published in Nature Communications. 

When University of Rhode Island researchers slipped beneath the surface of the Moosup River recently, they did not expect to find a living freshwater mussel community.

As sea levels rise and saltwater seeps into freshwater, stressed aquatic populations may retain overall growth even as diversity declines, MIT scientists find.
