There was a total of 65 unprovoked shark bites worldwide in 2025, slightly less than the most recent 10-year average of 72. Nine of last year’s bites resulted in fatalities, compared to the ten-year average of six.

For more than a century, researchers have suspected that glacier fronts serve as important feeding hotspots for marine predators with no direct evidence. To address this, researchers have examined the stomach contents of ringed seals harvested through Inuit subsistence hunting in Greenland and compared their diet with capture location. The findings show that seals near the glaciers had eaten more than those farther away, highlighting climate-driven glacier retreat may threaten foraging grounds and marine ecosystems.

17 February 2026 / Kiel / Las Palmas. Yesterday, an international team of researchers from various disciplines set off aboard the German research vessel METEOR for an expedition along the west coast of Africa, led by the GEOMAR Helmholtz Centre for Ocean Research Kiel. The expedition focuses on two poorly understood phenomena: the Benguela upwelling system off the coasts of Angola and Namibia, which partly operates independently of the wind, and the recurring marine heatwaves known as Benguela Niños, which have a significant impact on the local climate and cause flooding in Angola and Namibia.

Beneath the ice of West Antarctica lie natural records of past climate variability, containing sediments deposited during warmer periods when the region was partly or entirely ice-free. 

An international team co-led by a researcher from ETH Zurich and the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) has now retrieved the longest sediment core ever drilled from beneath an ice sheet, using a custom-designed drilling system. 

The 228 metre-long core contains geological evidence and fossils of marine organisms that indicate a previously open, ice-free ocean. This archive provides new insights into how sensitive the West Antarctic Ice Sheet is to a warming climate. 

A 40-year study using field data from Projeto Lontra reveals that Neotropical otters act as "living sensors" of ecosystem degradation, with 66% testing positive for land-based pathogens like Toxoplasma gondii carried by runoff. This research, published in Estuarine Management and Technologies, led to the creation of the Otter Health Index (OHI), a low-cost toolkit designed for muncipalities and NGOs to better monitor estuarine health through simple metrics.
