| 摘要： | Nonindigenous species (NIS) can be a significant concern in U.S. waters causing extensive economic and ecological impacts.Ballast water discharge from commercial vessels is a major pathway in which nonindigenous species can be introduced.Although the U.S. Coast Guard has regulations for ballast water discharge, there are no standardized measurements currentlyestablished to assess the performance of these management programs in most geographic regions. This project aims to establishsuch measures at a sentinel site in the U.S. Great Lakes, to be conducted as repeated measures over multiple years. This reportprovides recommendations and rationale for site selection and sampling protocols for field-based detection measures, asspecified in Year 1 of the project. The research team has selected Duluth-Superior harbor as a NIS sentinel site for this project,based on the relatively high volume of ballast water discharge, record of invasions, and partners with expertise at this focal site.The team is comprised of researchers from Smithsonian Environmental Research Center (SERC), USCG Research andDevelopment Center (RDC), and collaborators from international, national, regional and local agencies. The team draftedprotocols for field surveys to detect NIS and allow direct comparison to existing NIS sentinel sites in U.S. marine ports. Theprotocols detailed here involve sampling both the benthic and planktonic communities using a combination of habitatcollectors, sediment grabs, and plankton pumps. This suite of sampling methods will ensure that repeatable, standardized dataare collected, which will provide a comprehensive view of NIS presence within the areas sampled and how that relates toballast water management. |
