Cycling Through the Food Web: Let's Go on a Research Cruise

Comment on this resource
This site presents an account of a research cruise to investigate how the food webs in different oceanic habitats vary. The scientists wanted to see ocean life in its natural environment and conduct experiments that would not be possible in the laboratory. They looked specifically at three types of ocean habitat: the open ocean, the continental shelf, and an upwelling area. The researchers were hoping to learn the answers to two questions: 'How well do the actual marine food webs match our food chain models for the three habitats?' and 'How does the microbial community in each food web change with depth?'. Students can follow their research and fill out an activity and question checklist as they go along. There is also a page of information for teachers.
