Salmon life cycles from egg to spawning adults with text explaining each life phase.

This is fieldwork from a Chinook salmon egg survival pilot study in the Sacramento River. Egg boxes were placed in the river at different locations to collect data on egg-to-fry survival. Some examples of data collected include water velocity and river flow, gravel temperature, scour and deposition, and sediment type.

This is a photo of a cutthroat trout being measured. It will then be used in experiments to understand the sublethal effects of the toxic tire byproduct chemical, 6PPD-quinone.

In this image, scientists are exposing fish to the toxic chemical, 6PPD-quinone, to better understand the toxin's effects. This work is being done at the Western Fisheries Research Center wetlab. The science is then used to develop solutions to the toxin.

This video presents the Spring 2025 Saline Lake Ecosystems Integrated Water Availability Assessment Spring Seminar by the U.S. Geological Survey (USGS). Hosted by Allison Shipp, the seminar provides updates on how hydroclimatic changes and water management affect terminal lake ecosystems and waterbird populations.

Field technicians collect soil samples and monitor plants in an invasive grass dominated sagebrush steppe ecosystem in Colorado. The team measured carbon levels at two soil depths at undisturbed sites, sites that have been burned and invaded, areas that are unburned but invaded, and sites that were burned but not invaded.

When disaster strikes, near-real-time images of its effects can be invaluable. In this episode of Eyes on Earth, we learn about how a newly developed system using the Harmonized Landsat Sentinel-2 dataset and artificial intelligence was put to the test when Hurricane Ian tore through Florida in late September 2022.
