OB44B:
Beyond Just Discovery in the Ocean’s Midwater: Novel and Mechanistic Approaches to Understanding Mesopelagic and Bathypelagic Ecosystems III Posters

Session ID#: 85443

Session Description:
There is a long history of exploring the ocean’s midwater realm. However, a recent surge in focus on mesopelagic and bathypelagic ecosystems is leading to advances that are greatly enhancing our understanding of the dynamics, functioning, and importance of this massive region of the world’s oceans. We invite researchers around the globe focusing on any aspect related to the ocean’s midwater regime to come together to share their recent findings and, collectively, elucidate the current and future state of midwater research. Focus can span technological development, physics, biogeochemistry, biology, ecology, conservation, and management. Specific examples of such foci include: biomass and biodiversity measurements through the use of acoustics, optical imaging, genetics, and traditional net sampling; novel tools and technologies to study midwater properties and processes; life history characteristics and behaviors of midwater organisms, including those related to diel vertical migration; the role of midwater organisms in carbon flux; trophic pathways in midwater ecosystems, including the role of surface-water dynamics and the use of deep pelagic ecosystems by oceanic top predators; and implications of harvesting of midwater organisms and potential conservation and management strategies.
