©2026 Biological and Chemical Oceanography Data Management Office.The project investigates how the metabolic activity of dense aggregations of marine organisms alter the water chemistry of their interstitial spaces, and how these microscale alterations feedback to affect the organisms’ interactions in coastal ecosystems. The research evaluates whether corrosive chemical microclimates (such as low oxygen or low pH) are most extreme in low flow, high temperature conditions, especially for dense aggregations of mussels with large biomass and/or high respiration r...

This data is from a flume experiment undertaken at Friday Harbor Laboratories in July 2023 as part of a project investigating how the complex 3D structure and metabolic activity of dense aggregations of marine organisms can alter interstitial water chemistry, and how these microscale alterations affect interactions in coastal ecosystems.
This dataset presents:
1. Bulk seawater chemistry measurements using HOBO loggers for dissolved oxygen, pH/Temp, and Conductivity
2. Interstitial water chemistry measurements using Pyroscience microsensors for oxygen, pH, and temperature
Additional data on velocity and turbulence measurements using a Nortek Vectrino can be viewed at https://www.bco-dmo.org/dataset/982717 (see also Related Datasets section below).
