Labs

With the laboratories adjacent to the shore and equipped with running seawater aquaria, it is possible to work with fresh seaweed and phytoplankton samples in ways not possible in inland laboratories. This makes possible the following observations and analyses using live specimens. Some experiments may be carried out in the nearshore habitat using the floating dock or research boats and gear.

• Analysis of Structure: Analysis of the cellular and structural diversity found in phytoplankton and seaweeds and the developmental sequences resulting in their final form is accomplished by microscopical analysis and comparison of the major structural patterns that have evolved in marine algae.
  
  
• Reproduction and Life Histories: The different types of reproductive structures and the reproductive bodies they produce and their role in the life histories of marine algae also requires careful microscopic examination.
  
  
• Seaweed and Phytoplankton Identification: The procedures and resources required for seaweed and phytoplankton identification will be practiced in the lab. With practice, sight identification is possible for many species but some require diligent microscopic examination and knowledge of the literature for correct identification. Examination of sediments for microalgal cysts.
  
  
• Specialized Microscopy Techniques: Inverted microscope methods, phase contrast, Nomarski differential interference contrast, dark field microscopy, specimen preparation for scanning electron microscopy.
  
  
• Image Recording: High resolution video microscopy, conventional photomicroscopy.
  
  
• Photosynthetic and Other Pigment Systems in Marine Algae: Seaweeds and phytoplankton are noteworthy for the diversity of their photosynthetic and photoprotective pigment systems. Techniques for laboratory analysis of suitable samples will be practiced in the laboratory.
  
  
• Photosynthesis, Growth and Productivity Measurements: Practical techniques for measuring photosynthesis, growth and estimating productivity of marine algae in lab and field situations will be demonstrated.
  
• Seaweed and Phytoplankton Culture Methods: An important technique for experimental purposes ranging from basic developmental studies to transplanting clonal cultures in ecological experiments depends on growing algae in lab and field culture situations. Methods and media for doing this will be the subject of lab exercises and students will have an opportunity to initiate cultures of selected species.
