Summary

The Great Lakes Research Vessel Operations data release is taken from the Research Vessel Catch (RVCAT) database curated at the Great Lakes Science Center (GLSC). RVCAT has been used as the primary data collection tool aboard the GLSC’s research vessel operations. Content: The data set has been collected on various vessel operations on all the Great Lakes and select connecting waterways between the years 1958-2018. Data collection begins in early spring and ends in late fall. Each vessel operation was completed for a specific purpose, or target mission, which are enumerated in this data set. In addition to vessel operations data, RVCAT collects trawl and gillnet catch data, sample information of fish species caught, as well as effort [...]

Summary

The Great Lakes Research Vessel Operations data release is taken from the Research Vessel Catch (RVCAT) database curated at the Great Lakes Science Center (GLSC). RVCAT has been used as the primary data collection tool aboard the GLSC’s research vessel operations.

Content:
The data set has been collected on various vessel operations on all the Great Lakes and select connecting waterways between the years 1958-2018. Data collection begins in early spring and ends in late fall. Each vessel operation was completed for a specific purpose, or target mission, which are enumerated in this data set. In addition to vessel operations data, RVCAT collects trawl and gillnet catch data, sample information of fish species caught, as well as effort applied. The data set also contains data on benthos samples collected. Although not included in this data release, the GLSC collects or collected zebra mussel, hydroacoustics, ichthyoplankton, and zooplankton data in relation to vessel operations.

Data Structure:
These data are collected at the GLSC in the RVCAT Oracle database. The RVCAT database that is the basis for the following data release has been broken down into over 100 tables in order to facilitate greater accessibility. For ease of use, these tables are organized into conceptual groups – Operations, Trawl, Gillnet, Mensuration, Mysis, Benthos Ponar, and Reference. The database structure is described within the metadata record (XML) and entity relationship diagram within each concept group web page.

Data Release Method:
An updated version of the data will be published at least yearly, which will include new operations data, show any changes to the database structure, and have more quality control applied to the data from previous releases. The metadata will also be updated alongside these data releases in order to describe the data at that time of publication. See the revision history document to follow the structural changes to the database over each data release.

Data Quality:
Note that the following data release is a snapshot of the database at the time of release. Some data quality checks are still being undertaken after the time of release. Also, a large section of this database includes legacy data that if issues arise for cannot be addressed, but nevertheless adds great value to the database. When approaching the following data release, it is strongly suggested to approach the Great Lakes Science Center's researchers for input.

Distribution Liability Statement:
Unless otherwise stated, all data, metadata and related materials are considered to satisfy the quality standards relative to the purpose for which the data were collected. Although these data and associated metadata have been reviewed for accuracy and completeness and approved for release by the U.S. Geological Survey (USGS), no warranty expressed or implied is made regarding the display or utility of the data on any other system or for general or scientific purposes, nor shall the act of distribution constitute any such warranty.

Purpose

The Great Lakes Science Center (GLSC) has historically been the basin-wide leader in fisheries science in deepwater habitats. The data represented here were collected and used in connection with numerous research projects, reports to various organizations on Great Lakes' ecosystem health, and for longitudinal data about environmental conditions and species inhabiting the Great Lakes. Long-term data sets such as this have been used to understand how biotic and abiotic factors drive long-term fish community and population dynamics. As a result, the GLSC is well positioned to be a leading contributor to an emerging interdisciplinary approach to understanding Great Lakes food webs. The GLSC continues to develop ecosystem-level models that improve our understanding of food web structure and function, which also allow managers to explore different "what if" management scenarios.
