Levels of biodiversity and species ranges remain very poorly characterized across the CCZ, making predictions of the impacts of large-scale mining, for example the likelihood of species extinctions, very problematic. To understand and manage the impacts of nodule mining, it is critically important to survey biological community structure and ecosystem function across the entire CCZ region before mining begins.
However, eDNA approaches have seen limited application and ground-truthing in marine systems. Research proposed here will execute a comprehensive eDNA study across a range of deep abyssal habitats abyssal pelagic, abyssal seafloor, seamounts , encompassing both the eastern and western extremes of the CCZ. Proposed Research. The overarching goal is to test and evaluate the utility of the eDNA approach for biodiversity surveys in the deep sea, and to assemble databases of relevant DNA sequences from diverse deep CCZ habitats and communities in advance of nodule mining.
The specific project objectives are to:.

Exploration of biodiversity and ecosystem structure on seamounts in the western CCZ. Collaborators: Adrian Glover, Thomas Dahlgren.
Investigators: Craig R. Drazen co-PI , M. Church co-PI , A. Sweetman co-PI , A. Glover co-PI , T. Dahlgren co-PI , E. Goetze co-PI , E. Vetter co-PI.
The primary goals of the project are to provide at-sea cruise leadership experiences and training in oceanographic sampling for early career biological and chemical oceanographers. Participants will be involved in the design of the specific science objectives for the cruise, framed within the general context of quantifying biological processes that couple epi- and mesopelagic biogeochemistry and ecology in the oligotrophic North Pacific Subtropical Gyre NPSG.
Overview The most abundant metazoans in the open sea are often the earliest developmental stages of copepods, their nauplii. The study was conducted in northeastern Catalan coast, in La Fonera, also called Palamos, submarine canyon and is the continuation of a previous work where the impact of this method of fishing on the morphology and sedimentary dynamics of this canyon was evaluated.
According to Pere Puig, researcher at the ICM-CSIC who participated in the study, "the dragging of the gear on the seabed lifts and removes fine particles of sediment, yet also resuspends small organisms living in the sediment that constitute the base of the food chain at these depths. The work compares these kinds of impacts of trawling on marine sediments with the loss of fertile soil on land.

The paper concludes by warning about the ecological consequences and effects on ecosystem functioning and biodiversity of deep marine sedimentary environments around the world, where it was believed that the impact caused by this type of fishing were lower. The results of this study, therefore, reinforce the need for immediate action for the sustainable management of trawling in deep marine environments.
