Researchers from Sun Yat-sen University and Southern Marine Science and Engineering Guangdong Laboratory (Zhuhai) recently observed a species of armored searobin, Scalicus engyceros, walking sideways and backward on the sea floor in the South China Sea. This is the first time a species of fish has been observed walking backward.

For the first time, researchers have used data from narwhals to document how Atlantic water reaches deep into fjords along Greenland’s east coast. A new study from the University of Copenhagen sheds light on a poorly studied region, and the findings could have important implications for understanding and predicting climate change.

Study by University of Utah geoscientists creates 3D map of a hidden ‘rock glacier’ in the Wasatch Mountains, one of more than 800 in Utah. The team used their novel method of measuring these features to estimate the world’s 50,000 rock glaciers hold 48 cubic kilometers of water.

The use of fossil fuels alters both the concentration and the carbon isotope composition of carbon dioxide in the atmosphere. Since surface water exchanges carbon dioxide with the atmosphere, this also alters the isotopic composition of the carbon dissolved in the ocean. In a study, a team from MARUM – Center for Marine Environmental Sciences at the University of Bremen has now determined how deep this so-called Suess effect has already penetrated into the North Atlantic.

Researchers found that wildfire smoke and rain, through relatively infrequent, can deliver disproportionally large amounts of nitrogen, phosphorus and potassium to ecosystems. Analyzing satellite smoke observations and national network rainfall data from 250 sites across 16 climate regions in 2014, 2020 and 2022, the study found a striking increase in smoke-rain days in 2022 compared with 2014, with regional hotspots shifted from year to year. The findings show wildfire emissions can be an important source of material deposited into ecosystems, but not necessarily in a way that benefits growth or productivity.
