Modeled Ocean Acidification Impacts on Puget Sound Food Web

An Ecopath with Ecosim model simulates the biological consequences of ocean acidification on the Puget Sound estuary. Output calculates percent change in biomass for functional groups like calcifying molluscs, crustaceans, and demersal fish, as well as fisheries yield. This modeling study provides insight into potential shifts in ecosystem services and food web structure under acidification scenarios.

Use Cases

• Assessing ecosystem service changes based on modeled biomass shifts for functional groups.
• Evaluating fisheries management strategies under acidification using projected yield changes.
• Analyzing indirect food web effects from productivity declines in calcifying organisms.
• Comparing the relative vulnerability of different trophic groups, such as crustaceans versus demersal fish.

Strengths

• Dataset is hosted on multiple authoritative platforms (NASA EarthData and Data.gov), indicating recognized importance.
• Model output provides specific, quantified metrics: percent change in biomass and fisheries yield.

Limitations

• Column names and exact data structure are not provided in any source description.
• Conflicting last updated dates exist: one source lists 2013-03-17, while others list 2026-03 05, creating uncertainty about data currency.
• No information is provided on dataset size, row count, or license terms.
