Vertical export of particulate organic matter and fecal pellets off central Peru (Callao, 12°S) during the early 2023 El Niño event

Total mass flux (TMF) represents the export of all particulate material, both organic and inorganic, through the water column and plays a key role in biogeochemical cycling. The objective of this work was to quantify the TMF and assess the contribution of fecal pellets in Callao...

Field-Based Analysis of Saltwater Intrusion Distance, Arrival Time, and Stratification Index Following a Controlled Barrage Opening in the Nakdong River Estuary, South Korea

Saltwater intrusion in regulated estuaries is commonly assessed using intrusion distance; however, its response to barrage operation may also depend on arrival timing, vertical stratification, and bathymetrically influenced near-bed transport. This study investigated these proces...

Amazon Forgotten Fishes. How the remarkable diversity of freshwater fishes is critical to people, rivers and forest

Across the vast sweep of the Amazon Basin, thousands of rivers, streams and floodplain lakes flow in an immense, interconnected waterscape— home to an unparalleled diversity of freshwater fishes. More than 2,700 species have so far been recorded, with dozens more added each year...

A compilation of global bio-optical in situ data for ocean-colour satellite applications – version four

Abstract. A global in situ dataset for validation of satellite products from the ESA Ocean Colour Climate Change Initiative (OC-CCI) is presented. This version of the compilation, with data starting in 1996, extends to 2025, which is important for the validation of recent algorit...
