This dataset focuses on Pennypack Creek in Philadelphia, PA, where synoptic sampling was conducted in March 2022 along a 30 km stretch of stream. By collecting water samples under low-flow conditions, researchers aimed to assess groundwater contributions with minimal precipitation influence, providing insight into spatial variations in stream chemistry.

This dataset focuses on the concentrations of trace gases—carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O)—as well as the nitrogen-to-argon (N₂:Ar) ratio in stream water, providing insight into biological and chemical processes affecting aquatic ecosystems.

The Urban Critical Zone project examines how geology, urbanization, and human activities influence water quality in metropolitan streams along the Eastern Seaboard. This dataset includes bi-weekly water chemistry measurements collected from February 2021 to March 2024 in four watersheds

The GLEON 2025 All Hands’ Meeting will be held at Taman Simalem Resort, Lake Toba, North Sumatra, Indonesia on 17-21 February 2025 with pre-meetings and arrivals on 15-16 February and departures on 21-22 February.

Forests in the Western US have been living with fire for thousands of years. Some even benefit from fire. But climate change and a legacy of fire suppression are making today’s fires larger, more frequent, and more destructive. As a result, some forests and communities may never recover.

As trees grow, they take up carbon from the air and store it in their wood, roots, and soils. An estimated one-third of the carbon emissions released from burning fossil fuels are absorbed by the world's forests every year.
