Description of Collections: The LTER samples include zooplankton, phytoplankton, fish scales, Dendys (invertebrates collected with a Hester-Dendy sampler), pelagic invertebrate tows, and macrophyte samples (to search the collection, please click on the respective links below): 

• Zooplankton are wet samples, in formalin or ethanol, in 2 to 8 oz. jars in half-sized records boxes on open shelving.
• Phytoplankton have traditionally been stored wet but, a conversion to microscope slide format (some pooled samples remain in wet storage) has begun. The wet samples are stored on open shelving; the slide samples are stored in one of the metal “Tensco” cabinets.
• Fish scales are stored in small envelopes, organized in card-file boxes. The boxes are organized by lake and year, in one of the metal “Tensco” cabinets.
• Dendys are wet samples, preserved in ethanol, in vials and jars. The samples are organized in records boxes on open shelving.
• Pelagic invertebrate tows (vertical night tows) are wet samples in ethanol stored on open shelving.
• Macrophyte samples are dried and stored in boxes on open shelving.
