Full Citation Examples
These data include temperature and depth (pressure) recorded every minute while deployed on longline gear. They provide information on the depth at which both deep- and shallow-set gear are fishing, as well as ocean temperatures in the fished environment.
The purpose of this dataset is to further our understanding of:
- how longline fishing gear performs in the water column,
- subsurface ocean temperatures,
- the relationships between the physical environment and fisheries catch.
