Join us at NRNC for an outstanding talk dealing with Ocean Acidification and how we might be able to help.
Ocean Acidification Nearshore Monitoring Network (ANeMoNe): DNR research and volunteer monitoring opportunities
Peter Markos

The Washington State Department of Natural Resources manages 2.6 million acres of state-owned aquatic lands, including aquatic reserves that protect native habitats and areas used to grow shellfish. To support its interest in the health of state-owned aquatic lands, DNR manages the ANeMoNe program. ANeMoNe is a network of sensors placed around Puget Sound and along the Pacific coast to measure local changes in marine chemistry and the influence of eelgrass on local conditions. DNR is concerned about marine chemistry, because when the ocean absorbs carbon dioxide, pH in the water decreases, resulting in ocean acidification (OA). OA can affect shellfish by making it difficult for organisms to build shells and grow. DNR places ANeMoNe sensors in and around eelgrass beds, because eelgrass habitats can buffer local changes in chemistry due to their metabolic conversion of carbon dioxide to oxygen. The data collected through these sensors can be used to evaluate site-specific variability in pH, assess impacts to marine organisms, and identify potential sites that may be more exposed or buffered to changes in marine chemistry. We have established eight sites throughout Puget Sound, including sensors at the Nisqually Reserve. We need your help to maintain those sensors and to collect baseline data on changes in eelgrass, shellfish, and bird populations.

I’m an aquatic ecologist who has lived and worked in many places across the country. I am fortunate to have conducted stream monitoring projects in Ohio (I grew up in Cleveland) and Maryland and to have experienced the warm climates and species diversity of Louisiana (I went to graduate school at LSU) and Hawaii. I have lived in the Pacific Northwest for the last seven years and am impressed by the variety of aquatic habits and the immense natural beauty in our state. I have fond memories of “stopping to take a breath” while conducting scientific monitoring on mountain streams, estuary tide flats, and in bays along the Puget Sound. During my time at DNR, I have developed boat-based bathymetry and nearshore habitat monitoring studies, collaborated with coworkers to develop ANeMoNe sensor deployment strategies and protocols, and am now working to develop our ANeMoNe volunteer monitoring network. I look forward to engaging with citizen scientists to address ocean acidification issues in nearshore habitats across the sound and coast.
