Item Identification

Title: Rockfish Recruitment and Ecosystem Assessment Survey
Status: In Work
Creation Date: 1983
Abstract:

In 1983, the Groundfish Analysis Team began a series of annual surveys designed to assess the recruitment strength of juvenile rockfish and various economically and ecologically important species, and to examine the general state of the ecosystem and its variability along the central California coast. Midwater trawls were conducted and CTDs performed during late spring every year since 1983. Initially the survey area was Monterey to Point Reyes; however, in 2004 the geographic range was extended to San Diego through Mendocino.

Purpose:

To provide fishery independent data for stock assessments, to improve knowledge of the early life history of fishes, and to monitor trends and changes in the ecosystem and species assemblages.

Data Quality

Completeness Report:

For our trawl data we have a PROBLEM code to note if there were any issues e.g., winch problem so trawl retrieval took twice as long, large numbers of jellyfish so codend ripped and part of sample lost, etc. We have a STANDARD_STATIONS variable that is based on the PROBLEM code with STANDARD_STATION=1 is a problem free trawl and STANDARD_STATION=0 is a trawl that had some sort of problem (makes the data non-quantitative). For statistical analysis and for general distribution to the public (e.g., posting our data on ERDDAP) we subset the data to exclude problematic trawls. In addition, various species have been identified and enumerated at sea differently over the years, e.g., krill were not identified to species until 2002.

Quality Control Procedures Employed:

Data are checked at sea by comparison with data sheets. Species identifications are confirmed for most species on shore.

Docucomp UUID: dfe238e9-703a-451c-af6b-29ba1b192468
Description:

The fourth vessel of its kind, Bell M. Shimada offers fisheries scientists the ability to monitor fish populations without altering their behavior, allowing them to collect data with unprecedented accuracy. With better data, biologists and oceanographers can help managers make better management decisions. In the Pacific, Bell M. Shimada will help scientists gain valuable insight into the California Current Large Marine Ecosystem, a globally significant natural resource that stretches from Baja California to British Columbia. Two scientists at the Center recently described some of the way in which this vessel will enhance existing or open opportunities for new research projects.

Description:

The Miller Freeman was decommissioned on 3/29/13 after many years of exemplary service. Pictures of the ceremony will be posted here when available - please check back soon. Miller Freeman was a 215-foot fisheries and oceanographic research vessel and was one of the largest research trawlers in the United States. Miller Freeman's primary mission was to provide a working platform for the study of the ocean's living resources. The ship was named for Miller Freeman (1875-1955), a publisher who was actively involved in the international management of fish harvests. The ship was launched in 1967, but not fully rigged until 1975. The vessel was again re-rigged in 1982. Miller Freeman was homeported at the Marine Operations Center-Pacific in Newport, Oregon. With a 12,578 mile / 31 day endurance, Miller Freeman was capable of operating in any waters of the world. Miller Freeman was owned by the United States of America, Department of Commerce's National Oceanic and Atmospheric Administration. The ship was operated by NOAA Marine and Aviation Operations and carried a complement of 7 NOAA Corps officers, 27 crew members, and maximum of 11 scientists.

Identifier: Reuben Lasker (RL)
Docucomp UUID: 12aa6b14-b49e-4e7e-8f36-5bfca5a4369b
Description:

Funded under the American Recovery and Reinvestment Act and built by Marinette Marine Corporation in Wisconsin, the ship's primary objective is to support fish, marine mammal, and turtle surveys off the U.S. West Coast and in the eastern tropical Pacific Ocean. The ship has a low sound signature to reduce reactions of fish to the presence of the ship and provides for a low signal-to-noise ratio for acoustic sensors. This allows scientists to study fish populations and collect oceanographic data with fewer effects on fish and marine mammal behavior. The multi-frequency scientific sonars provide the ability to conduct acoustic surveys that can distinguish fish types, estimate biomass, determine fish school shapes, and provide data on sea floor topography. Reuben Lasker is also equipped with oceanographic sampling and measurement systems, instrumented trawls, longlines, and plankton nets for direct sampling. The ship has a dynamic positioning system to steer along a pre-determined trackline and to accurately hold the ship in a fixed position. The ship is also equipped with meteorological data collection systems and has extensive wet and dry labs to provide maximum utilization of every hour at sea. These technologies will dramatically improve the ability to conduct diverse data collection operations as required by its mission. The ship is named after Dr. Reuben Lasker (1929-1988), who served as the Director of SWFSC's Coastal Fisheries Division and as adjunct professor at Scripps Institution of Oceanography, U.C. San Diego. Dr. Lasker built a renowned research group that focused on the recruitment of young fish to the adult population - a topic with implications for fisheries management throughout the world.
