Description

"Cooperative Long-term Ecosystem Monitoring in the Gulf of Maine"

Project leader: Jeffrey Runge (UNH)
Project assistant: Rebecca Jones (UNH)
Industry participants: Yankee Fisherman's Coop and Portsmouth Fisherman's Coop.
Monitoring Advisory Panel: R.Barnaby (UNH), C.Goudey (MIT Sea Grant), S.Meeker (UNH Sea Grant Extension), L. Mercer (Maine, DNR), D. Mountain (NMFS, Woods Hole), C. Pendleton (NAMA), D. Townsend (UMaine)

The overall goal of this project is the design and development of a cooperative, industry-based contribution to monitoring of the pelagic ecosystem in the Gulf of Maine. The need for long-term biological data collection in the Gulf of Maine becomes critical in light of increasing evidence for change in New England's climate. It becomes increasingly important for the fishing industry as decisions about fishery management shift from a single or multi-species to an ecosystem-based approach. By involving the expertise and resources of the local fishing community, we hope to learn more about the natural and man-made variability of the Gulf of Maine marine ecosystem.

Sampling took place on a weekly schedule with the cooperation of Portsmouth Fishermen's COOP and Seabrook Yankee Fishermen's COOP fishermen. Each week we visited the two stations shown on the above map, GoMOOS Buoy "B" and New Scantum at the southern edge of Jeffreys Ledge.

Associated datasets: see ctd_pulse, nuts_pulse, drywt_pulse, and zoop_pulse for more data from this study.

Methods & Sampling

Dataset acquisition description

Data collected during time series, 2003-2005: temperature, salinity, chlorophyll a (at 6 depths), nutrients (phosphate, nitrate, ammonium), zooplankton biomass, abundance and composition at each station (total of 93 stations at Buoy "B" and 87 stations at Jeffreys Ledge over 3 years).

Samples taken are a CTD (SeaCat 19 plus) cast for salinity, temperature, density, and fluorescence; 2 vertical ring net tows with a 200 micron mesh for zooplankton and ichthyoplankton assemblages and abundance; and water samples taken from every 10 meter depth from 0-50 meters for nutrient and chlorophyll-a profiling as well as phytoplankton assemblages.

Deployment-specific acquisition description

1. Interactions with a Steering Committee (the Monitoring Panel) to guide the design,
implementation, and analysis of industry participation in a pilot program.
2. Create a process to encourage broad industry participation, and to select fishermen
and fishing vessels for participation in the collection of time series samples.
3. Establish a laboratory at the University of New Hampshire for the analysis of
oceanographic field samples for ecosystem monitoring, using standard biological
oceanographic procedures. Obtain necessary field and laboratory equipment for data
and sample analysis. Provide training workshops to provide general and hands-on
experience for commercial fishermen in the laboratory protocols
4. Establish procedures for data collection, quality control, database management, and
analysis of results.
5. Coordinate with ongoing research and monitoring efforts by local, state, regional, and
national programs.
6. Organization of training workshops and seminars for commercial fishermen.
7. The scientific results: Implementation of a two-year project to collect and analyze
samples at the two fixed stations
