GEOTRACES will help us understand the ocean environment Today’s Video of the Day from the National Science Foundation describes GEOTRACES, an international research project which aims to improve our understanding of complex ocean processes such as nutrient cycling.
Scientists from 36 countries are collaborating to map the global distribution of trace elements and isotopes in the ocean. The goal is to understand how these elements affect marine productivity and climate change.
The data collected for GEOTRACES will help scientists predict the future of the ocean environment based on changes in the past. The concept of cycle describes the pathway by which a chemical element moves through the three major compartments of Earth (such as continents, atmosphere, and ocean). The GEOTRACES Intermediate Data Product consists of two parts: the digital data package and the eGEOTRACES Electronic Atlas.
GEOTRACES will be global in scope, consisting of ocean sections complemented by regional process studies. Sections and process studies will combine fieldwork, laboratory experiments and modelling. GEOTRACES will help us understand the ocean environment as shown above in the video showing you the entire process as well as study of the global marine biogeochemical cycles of trace elements and their isotopes.
