New Sampling Method: Longlining
The Marine Reserves research team uses longlines to research the diversity of fish species found in Redfish Rocks Marine Reserve. Check out this post to learn more about longline gear and how we use it Read More
Scientific Divers to Survey Otter Rock Marine Reserve
Volunteer scientific divers are practicing their survey skills in Otter Rock Marine Reserve this week. Scientific divers play a integral role in conducting ecological research in Oregon’s Marine Reserves. We use diver based underwater visual census methods to identify and count macroalgal, invertebrate, and fish communities. Read More
