SCMI standard demonstration cruise consist of 4 stations: Water Station, Biological Dredge station, Otter Trawl Station, and the Horizontal Plankton Haul Station. During the water station students are introduced to the use of a Secchi disk to determine turbidity, and the YSI CTD to determine physical properties of the water. The biological dredge station is used to collect benthic organisms and sediment samples. The otter trawl station is used to sample bottom dwelling fish and invertebrates. The horizontal plankton haul station is used to collect plankton samples which can be viewed and identified under the microscopes. These demonstration cruises allow students to experience the ocean processes and examine physical, biological ,and chemical properties of the ocean environment.
