  1. The Macroalgal Herbarium ConsortiumAccessing 150 Years of Specimen Data to Understand Changes in the Marine/Aquatic Environment Janet Sullivan and Chris Neefus University of New Hampshire Consortium of Northeastern Herbaria meeting Montréal, June 2014

  2. What are Macroalgae? four divisions in two kingdoms Eukaryota Tree of Life (Bauldauf 2003)

  3. What are Macroalgae? Rhodophyta (Red Algae) - 6,300 species in 10 orders Chlorophyta (Green Algae) - 4,300 species in 15 orders Charophyta - 3,500 species in 8 orders Phaeophyta (Brown Algae) - 2,000 species in 18 orders

  4. How are they important? • Foundation of aquatic ecosystems – provide food, shelter and substrate for other organisms • Maintain nutrient balance in aquatic ecosystem and produce oxygen • $7.4 billion industry as human food, phycocolloids, pharmaceuticals • Sensitive indicator of environmental changes in aquatic ecosystems Photographs by Robert Lücking

  5. What is the Macroalgal Herbarium Consortium? • 49 institutions in 26 states and U.S. possessions • 1.2 million specimens in collections ranging from 100 to 200,000 • Project goal is to digitize (image, database, georeference) all of them

  6. Macroalgal Consortium Herbaria Red = 6 PDCs Yellow = 12 DCs Blue = 31 CIs

  7. Workflow – Step 1 • Any pre-digitization curation • Barcode placement

  8. Workflow – Step 2 Skeletal label data captured in Excel or .csv file

  9. Workflow – Step 3 • High-Resolution Image Captured • Lightbox/copystand • 21 to 36 megapixel camera • Camera Control Software • Adobe Lightroom (white balance, tone curve adjustment, .jpg & .dng export) http://macroalgae.unh.edu

  10. Workflow – Step 4 Image and label data uploaded to portal (http://macroalgae.org)

  11. Family classifications and authors from AlgaeBase via WoRMS

  12. Workflow – Step 5 Additional label data transcribed from within the portal

  13. Workflow – Step 6 Specimens are georeferenced from within the portal

  14. Information Sharing Data portal – http://macroalgae.org Consortium Website – http://macroalgae.unh.edu

  15. Broader Impacts of the Project • Undergraduate and Graduate Student Participation • Training in Imaging, Data Transcription, Georeferencing • Research Opportunities • 2. Internships at NY Botanical Garden and Field Museum • 3. Exhibits and Programs • Field Museum (650,000 visitors) • Bishop Museum (450,000 visitors)

  16. Broader Impacts of the Project 4. Research Applications • Systematics • Floristic Diversity and Biogeography • Historical Comparisons • Assessing human impact on coastal environments • Assessing the impact of climate change on species distribution • Tracking introduced and invasive species
