Oceanographic Study of Conception Bay: Interconnections of Physical, Geological, and Biological Aspects

This study conducted on the ship Anne S. Pierce over 1.5 days focuses on the oceanographic dynamics in Conception Bay. The research analyzes three critical aspects: physical, geological, and biological oceanography. Five fixed stations and two ADCP transects were utilized, along with various equipment such as sonar and bottom grab samplers, to gather data. The primary question addressed is how these three domains interconnect within the bay, offering insights into the ecosystem's health and sustainability.
