JASON VII
April Expedition
Fish Science Team
- Jim Bohnsack (host researcher)
- NR-1 EATS team: Jon Howland (imaging), Dana Yoerger (navigation), Paul Donaldson (ROV pilot), Ivar Babb (ROV director), Greg Beers (pilot), Nick Worobey (ROV engineer)
- Student and Teacher Argonauts: Week One: Martha Alexander, Kristin Cooper, Manish Kumar; Week Two: Rebecca Carino, Sarah Evans, Heidi Kuglin, William Sarkis Jr.
- Diving Argonauts: Week One: Jude Kesl, Leigh-Ann Shaw, Geoffrey Szymanski; Week Two: Sandra Moffett, Justin Mann, Derek Pettigrew
Locations/Science:
- Molasses reef (back reef)
On Sundays an alpha survey will be conducted on an inside reef. The relative numbers and species will be counted. Different areas within the site will be compared (e.g.. rough terrain, high profile etc., presence/absence of coral).
The key research question is:
- Are all locations within the site the same? (Null hypothesis) If not, why are they different?
- Conch reef (diving argonauts)
During the dive with Dr. Wellington on Conch reef, argonauts located here would also conduct an alpha survey of an outer reef. Different areas within the site could be compared. Information would be forwarded to the fish group for analysis.
The key research question is:
- Are all locations within the site the same? (Null hypothesis) If not, why are they different?
- Wreck
The same alpha survey would be conducted on the wreck using the NR-1 with a student argonaut aboard. This would involve moving the NR-1 in a circle. The ROV could show the NR-1 moving for the survey.
The key question is:
- What species of fish are found here? (This site has never been surveyed before)
- Humps
The same alpha survey with the NR-1 EATS team.
The key question is:
- What species of fish are found here? (This site has never been surveyed before)
For comparison of data between the sites, bar charts and mosaic images will be produced. The following key questions relate to the compilation of data:
- What fish species are found at the different types of reefs and the relative abundance?
- How does this relate to fishing practices or access to the reefs?
- How many herbivores versus predators are present?
- What is the average size of each species found at the different reefs?
- How does an “artificial” reef of the wreck compare with the “natural” reefs?
