The Hourglass Cruise Comprehensive Digitization Project; Specimens, Data, Ships Logs, and Memoirs of the 1960's Gulf of Mexico Sampling Program

Material Description

The 1960's Hourglass Cruise sampling program was one of a kind for its systematic approach; repeated returns to sampling stations in various weather conditions, times of day, month, and year was a inspired approach at the time. Karen Steidinger, a current FWRI biologist researching marine dinoflagellates, was one of the original crew members of the HGC. She is still with FWRI, has provided a letter of support, and will assist with deciphering the data. The field notes to be digitized are the original HGC handwritten sampling notes on “Field Data” forms with information on date, time, and location by station, weather condition, sampling gear, hydrology, depth, specimen notes and remarks. They are completed by project; the data provided changes with the focus of the project. The fish larvae project field notes have ichthyoplankton data. Gonad and otolith data were taken at the lab, this information is compiled in a separate collection of data sheets. The nearly 5000 cataloged vertebrate lots include specimens representing 75 families and 267 species of fish, including bony and cartilaginous (sharks, skates, and rays) groups. These were collected by Robert F. Presley aboard the R/V Hernan Cortez from 1965 to 1967. Samples represent a range of depths and latitudes on the Florida Shelf in the northeastern Gulf of Mexico.
