| Short Description |
This document is a summary for scientists of the findings of the study "Relationships between the Composition of the Benthos and Sediment and Water Quality Parameters in Hood Canal" (linked below). Analysis of Hood Canal data collected from 1932 to 2005 revealed that sediment texture was the most important factor controlling invertebrate community composition, followed by dissolved oxygen, organic carbon content of the sediments, and station depth. Steps were taken in this report to develop initial critical dissolved oxygen thresholds used to determine when benthic infauna are at risk. (Also see abstract below) | |||

| Abstract | Long Description |
As part of the Hood Canal Dissolved Oxygen Program, sediment quality, water-column dissolved oxygen, and sediment-dwelling invertebrate (benthic infauna) data from Hood Canal studies from 1932 to 2005 were gathered. These data were examined to (1) determine their characteristics in Hood Canal, (2) evaluate their relationship to each other, and (3) determine how low dissolved oxygen may affect benthic infauna in Hood Canal. |
